Why we added ENERGYbits® to the PraveBio.cz range
Catharine Arnston founded ENERGYbits® in 2010 after her younger sister was diagnosed with breast cancer. While researching nutrition, she began exploring algae.
- The same Taiwanese grower for more than 10 years, with nearly 50 years of experience in algae cultivation.
- Outdoor freshwater ponds supplied with mountain spring water filtered through three stages.
- Low-temperature drying and direct compression with no fillers, binders or anti-caking agents.
- Traceable batch documentation, including the published laboratory report for batch V6419.
Single-ingredient spirulina with clearly documented sourcing and processing. PraveBio.cz is the exclusive importer and distributor of ENERGYbits® for the Czech Republic and Slovakia.
ENERGYbits® Spirulina – origin, processing and batch testing
The spirulina is grown in outdoor freshwater ponds in Taiwan using mountain spring water filtered in three stages. Because spirulina can absorb substances present in the water as it grows, the origin of the raw material, growing conditions, processing methods and batch-specific testing are all important when choosing a product.
The laboratory report for batch V6419 records 68.56% crude protein, 1,078 mg of chlorophyll a, 217 mg of carotenoids and 6,933 mg of phycocyanin per 100 g. The batch met the stated specifications for the microbiological parameters and heavy metals covered by the report. View the laboratory report for batch V6419.
Swallowing the tablets whole limits contact with spirulina’s distinctive taste. In its general guidance for the US market, the manufacturer recommends a minimum of 10 tablets per day; at this intake, the 360-tablet pack lasts approximately 36 days and the 1,000-tablet pack approximately 100 days. The recommended daily amount stated on the current Czech-language label always takes precedence.
Spirulina, chlorella or both?
Spirulina and chlorella are often sold side by side, but they are not the same ingredient. ENERGYbits® is the name of the spirulina range; the brand’s other product lines are named according to the algae they contain:
- ENERGYbits® – 100% spirulina Arthrospira platensis, a blue-green cyanobacterium naturally rich in protein and the pigment phycocyanin. The manufacturer recommends taking it primarily in the morning and during the day.
- RECOVERYbits® – 100% chlorella Chlorella vulgaris with a cracked cell wall. This is the brand’s dedicated chlorella range.
- VITALITYbits® – spirulina and chlorella in a 50:50 ratio for customers who want both spirulina and chlorella in a single tablet.
Documented information on origin and quality
- Certifications and ingredient identification – the current original packaging displays the USDA Organic and Ecocert Organic certifications; the manufacturer also identifies the product as Non-GMO Certified. Czech product documentation identifies the ingredient as Arthrospira platensis; the manufacturer also uses the name Spirulina platensis on its website.
- One long-term growing partner – the spirulina has been sourced from the same Taiwanese grower for more than ten years. The grower has almost 50 years of experience in algae cultivation and operates in accordance with GMP and ISO 9000 standards.
- From pond to pack – cultivation takes place in outdoor freshwater ponds using mountain spring water filtered in three stages. Water purity, pH and nutrient composition are monitored daily. After harvesting, the spirulina is dried at a low temperature, directly compressed without fillers and packed in a UV-protective pouch that is vacuum-sealed during production.
According to the manufacturer’s current information, testing takes place at three stages: at the farm, after the tablets are produced in Taiwan and after arrival in the United States. Bacteria and moulds are tested in every batch, while heavy metals and toxins that may be produced by contaminating organisms are tested annually. An extended nutritional panel is carried out approximately every one to two years. The published laboratory report documents the specific results for batch V6419.
Suitable for
Important information
Before using the product for the first time, check the current Czech-language label on the specific pack:
- Follow the recommended directions for use and all information stated on the current label.
- This food supplement is not a substitute for a varied and balanced diet and a healthy lifestyle.
- Do not exceed the recommended daily amount stated on the current Czech-language label.
- Before giving the product to children or using it during pregnancy or breastfeeding, consult a doctor or another suitably qualified healthcare professional about its suitability and the appropriate intake.
- If you have an allergy to algae, a diagnosed medical condition or regularly take medication, consult a doctor or pharmacist before adding the product to your routine.
- In its general guidance for the US market, the manufacturer suggests that first-time users start with 5–10 tablets per day and gradually increase the amount over approximately one week. This explains the brand’s suggested routine and does not replace the recommended daily amount stated on the current Czech-language label. If you are sensitive to the earthy taste, swallow the tablets whole rather than chewing them.
- Keep out of reach of children and store in a cool, dry place, away from direct sunlight, moisture and sources of heat. Always follow the storage instructions on the current label.

What distinguishes ENERGYbits® from lower-priced spirulina products?
- A specialist brand since 2010 – Catharine Arnston founded ENERGYbits® in 2010 and built the brand around spirulina and chlorella.
- The same grower for more than ten years – the ingredient comes from one Taiwanese partner with almost 50 years of experience.
- Clearly described cultivation conditions – outdoor freshwater tanks, natural sunlight, mountain spring water filtered in three stages and daily monitoring of the growing environment.
- Low-temperature drying and direct compression – slower drying at a low temperature and compression without fillers, binders, anti-caking agents, gelatine capsules or preservatives.
- Three control points – checks at the farm, after processing in Taiwan and after arrival in the United States; the published laboratory report identifies batch V6419.
- Packaging designed to limit exposure to light and air – the UV-protective pouches are vacuum sealed during production.
- Manufacturer-declared sales volume – ENERGYbits® reports sales of more than 200 million algae tablets; this is a figure stated by the brand, not an independently audited statistic.
A higher price does not prove quality, and a lower-priced spirulina is not automatically inferior. The difference lies in the amount of traceable information and the number of documented control steps. ENERGYbits® provides information on the country and cultivation method, water source, certification marks, production process, long-term grower relationship, control system and packaging type; the laboratory report also allows customers to review the results for batch V6419. Customers are therefore paying not only for 250 mg of spirulina per tablet, but also for a more transparent supply chain and more accessible documentation.
Understanding the names ENERGYbits®, RECOVERYbits® and VITALITYbits®
ENERGYbits® is both the name of the American brand and the name of its 100% spirulina product line. We therefore do not use BITS® here as the name of a separate brand; both the brand and its spirulina line use the ENERGYbits® name.
The same brand also offers RECOVERYbits® with 100% chlorella, VITALITYbits® combining spirulina and chlorella, and BEAUTYbits® with spirulina on the US market. The word “bits” refers to the small compressed format, which the manufacturer describes as “bits of food”.
This product contains only 100% spirulina Arthrospira platensis. Each tablet provides 250 mg of spirulina; chlorella, synthetic vitamins and other active blends are not included. The available pack sizes contain 360 tablets / 90 g or 1,000 tablets / 250 g.
The tablets can be swallowed, chewed or blended into a drink. For customers who are sensitive to the earthy taste, swallowing them whole is the most practical option. Unlike chlorella, spirulina does not require the same cell-wall-disruption step before consumption.
ENERGYbits® product lines available from PraveBio.cz
- ENERGYbits® – 100% spirulina Arthrospira platensis.
- RECOVERYbits® – 100% chlorella Chlorella vulgaris with a cell wall cracked using sound vibrations.
- VITALITYbits® – spirulina and chlorella in a 50:50 ratio in a single tablet.

Why choose ENERGYbits®?
The brand and its spirulina line share the same name. ENERGYbits® is the American brand founded by Catharine Arnston and also the name of its original 100% spirulina range. RECOVERYbits®, VITALITYbits® and BEAUTYbits® are other product lines from the same brand, not separate brands.
Catharine Arnston founded ENERGYbits® in 2010 after her younger sister was diagnosed with breast cancer. Her interest in algae began while helping her research nutrition, and she built the brand around spirulina and chlorella.
Its specialist focus is backed by a long-term supply relationship. The ingredient has come from the same Taiwanese grower for more than ten years, and the grower has almost 50 years of experience. ENERGYbits® also reports sales of more than 200 million algae tablets.
The price difference reflects specific, documented steps across the supply chain. These include spring water filtered in three stages, outdoor tanks monitored daily, low-temperature drying, direct compression without fillers, binders or anti-caking agents, checks at several points and light-protective packaging.
Direct import adds local accountability. PraveBio.cz works with original packs, current Czech-language product information and available batch documentation. Customers can therefore raise questions about provenance, labelling or a particular batch report directly with the exclusive importer for the Czech Republic and Slovakia.
Two organic certification marks
Current original retail packs display USDA Organic and Ecocert Organic; the manufacturer also describes the product as Non-GMO Certified.
One grower, long-term continuity

How to read the tables: the laboratory values apply to batch V6419 and do not replace the current product label. Information about cultivation, certification marks and the three-stage control process is based on current manufacturer materials and packs physically verified by PraveBio.cz. For a well-founded assessment, consider the combination of traceable provenance, information on the pack, a batch-specific laboratory report and a straightforward single-ingredient formula.
How to assess the quality of this spirulina
Spirulina (100%)
What it is: single-ingredient Arthrospira platensis spirulina with no chlorella or added active blends.
What can be verified: the laboratory report for batch V6419 records 68.56% crude protein and gives precise values for phycocyanin, chlorophyll a and carotenoids.
Why it matters: customers can assess specific laboratory values rather than relying solely on a broad “rich in nutrients” claim.
Protein and amino acids
What can be verified: the laboratory report for batch V6419 records 68.56% crude protein. The manufacturer's nutritional materials list all nine essential amino acids, although the laboratory report itself does not include an amino-acid profile.
Practical context: 10 tablets provide only 2.5 g of spirulina, so ENERGYbits® are not a substitute for a standard serving of protein powder.
Who it may suit: customers who want to add a small amount of single-ingredient spirulina rather than maximise their protein intake in one serving.
Phycocyanin, chlorophyll and carotenoids
What they are: naturally occurring pigments characteristic of spirulina.
What the laboratory report shows: batch V6419 contained 6,933 mg of phycocyanin, 1,078 mg of chlorophyll a and 217 mg of carotenoids per 100 g.
What this does not prove: the presence of these pigments alone is not evidence of a therapeutic or guaranteed health effect.
Water, certification and testing
Verified on the pack: USDA Organic and Ecocert Organic.
Stated by the manufacturer: Non-GMO Certified, outdoor freshwater tanks in Taiwan, three-stage-filtered spring water, low-temperature drying and three control points.
Documented by PraveBio.cz: a published laboratory report for a specific batch and direct import of original packs.
What does this mean when choosing?
- Start by comparing the species, provenance and laboratory documentation – “100% spirulina” alone does not tell you where or how it was cultivated or which checks the product has undergone.
- Format matters in everyday use – small tablets remove the need to measure out powder and can be swallowed without experiencing the pronounced taste of powdered spirulina.
- A premium price needs concrete reasons – for ENERGYbits®, these include a long-term grower, certification marks, the stated water source, low-temperature processing, three control points, light-protective packaging and accessible batch documentation.
Suggested use
- General manufacturer guidance for the US market: the manufacturer presents 10 tablets per day as its standard routine and also gives model routines of 20 and 30 tablets. For those new to algae supplements, it suggests starting with 5–10 tablets per day and increasing the amount gradually over approximately one week. The tablets may be taken in the morning or during the day, with or without food; the manufacturer also mentions taking them approximately 30 minutes before physical activity. These examples explain the brand’s suggested routine and are not an instruction to exceed the recommended daily amount. If you are sensitive to the earthy taste, swallow the tablets whole rather than chewing them. The directions on the current Czech-language label always take precedence.
Important information
- Store in a cool, dry place, away from direct sunlight, moisture and sources of heat. Always follow the storage instructions on the current label.
- Allergens: according to the current label, the product may contain traces of nuts and sesame. If you have an allergy, always check the specific pack.
- For children, during pregnancy or breastfeeding, or if you have a diagnosed medical condition or take medication regularly, consult a suitably qualified healthcare professional about suitability.
- Do not use the product if the pack is damaged or if you notice an unusual change in appearance, aroma or taste. Reseal the pack securely after every use and protect it from moisture.
Customer ratings and practical reasons to choose ENERGYbits®
★ 4.89/5 (916 reviews) — rating displayed on the manufacturer's product page and verified on 23 July 2026 (source). The manufacturer also reports sales of more than 200 million algae tablets; this is a brand-declared figure, not an independently audited statistic.
1. No measuring, no blender and less exposure to the taste
The tablets can simply be swallowed, so there is no need to prepare a green drink or deal with spilled powder. If you are sensitive to the taste, swallowing rather than chewing them is the more practical option.
2. A single-ingredient formula
The formula contains only 100% spirulina Arthrospira platensis. It contains no blend of multiple algae, no synthetic vitamins and no proprietary combination of additional active ingredients.
3. A traceable grower and production process
The brand has worked with the same Taiwanese grower for more than ten years and provides details of the grower’s experience, water source, low-temperature drying and direct-compression process.
4. Quality control described in greater detail
This goes beyond a general “laboratory tested” slogan. The manufacturer describes three control points and different testing frequencies; PraveBio.cz also publishes the laboratory report for batch V6419.
5. Packaging and format designed for a regular routine
The pouch protects the contents from UV light and is vacuum sealed during production, helping to limit exposure to light and air before opening. The small tablets are easy to carry without a scoop and can be taken in the morning, during the day or before activity.
The rating comes from the manufacturer’s website. Individual customer experiences are not presented as proven health effects, and the number of reviews changes over time.
FAQ
Why are ENERGYbits® more expensive than many other spirulina products?
The price reflects more than the weight of the spirulina alone. ENERGYbits® provides information on the precise identification and provenance of the ingredient, its long-term grower, water source, certification marks, low-temperature drying, direct compression without fillers, three control points and light-protective packaging; PraveBio.cz also publishes a laboratory report for a specific batch. A lower-priced spirulina product is not automatically poor quality, but it is worth checking which of these details the brand actually makes available.
How can you recognise high-quality spirulina?
Check the precise spirulina species, country and method of cultivation, water source, certifications, drying method, full tablet composition and availability of laboratory documentation. It is also important to distinguish a general marketing claim from laboratory documentation that identifies a specific batch and shows the actual parameters assessed.
Can spirulina contain heavy metals, toxins, bacteria or pesticide residues?
Yes. Quality can be influenced by the environment in which spirulina is cultivated and by subsequent processing. The ENERGYbits® laboratory report for batch V6419 records compliance with the specifications for the heavy metals and selected microbiological parameters covered by the report. The published one-page laboratory report does not include a separate panel for pesticide residues or toxins produced by contaminating organisms; the manufacturer states that the spirulina is cultivated without pesticides and that these toxins are tested annually within its wider quality-control programme.
Are spirulina tablets better than powder?
When the raw-material quality is comparable, the difference is mainly practical. Powder is easy to add to smoothies and measure in larger amounts, but its taste is more pronounced and it can create mess. Tablets are easier to carry, can be counted individually and swallowed without a blender. Each ENERGYbits® tablet weighs 250 mg, so a higher intake by weight requires a larger number of tablets.
Is spirulina a reliable source of vitamin B12 for vegans?
Conventionally produced spirulina should not be relied upon as the sole source of vitamin B12. Inactive B12 analogues may account for a substantial proportion of the value reported for standard commercial spirulina by some analytical methods. Vegans should therefore use a reliable vitamin B12 source with a clearly stated active form and dose rather than relying on spirulina alone.
What is the difference between spirulina and chlorella?
Spirulina Arthrospira platensis is a cyanobacterium commonly described as a blue-green microalga and naturally contains the pigment phycocyanin. Chlorella Chlorella vulgaris is a green freshwater microalga with a rigid cell wall. For RECOVERYbits®, the manufacturer states that the cell wall is cracked using sound vibrations. ENERGYbits® contain spirulina only, RECOVERYbits® contain chlorella only, and VITALITYbits® combine both ingredients in a 50:50 ratio.
How much spirulina should you take each day, and when?
In its general guidance for the US market, the manufacturer presents 10 tablets per day, equivalent to 2.5 g of spirulina, and also gives model routines of 20 and 30 tablets. New users are advised to begin with 5–10 tablets and increase the amount gradually over approximately one week. The tablets may be taken in the morning or during the day, with or without food. These are manufacturer examples, not an instruction to exceed the recommended daily amount. The current Czech-language label and individual tolerance always take precedence.
Will ENERGYbits® break an intermittent fast?
According to the manufacturer's nutritional information, each tablet provides approximately 1 kcal, so ten tablets do not represent zero energy intake. Whether this fits your approach to intermittent fasting depends on the purpose and rules of your particular routine. During a strict calorie-free fast, it is more accurate to assume that energy is being consumed; we therefore do not present the marketing claim “will not break a fast” as a universal fact.
Can ENERGYbits® replace protein powder or a regular meal?
Not in the usual serving. Spirulina has a high proportion of protein in its dry matter, but 10 tablets provide only 2.5 g of spirulina and approximately 1.7 g of protein based on the value recorded for batch V6419. The product is therefore not a like-for-like replacement for a protein shake or a complete meal. Its advantage is a small amount of single-ingredient spirulina in a portable format.
Who may find spirulina suitable, and who should take extra care?
The product may suit active adults, athletes, fitness enthusiasts, biohackers, frequent travellers and adult vegans who want single-ingredient spirulina in a portable tablet format. These examples describe likely users; they are not claims that the product delivers a particular health or performance effect. For children, during pregnancy or breastfeeding, consult a doctor before use. Professional advice is also appropriate if you have an allergy to algae, a diagnosed medical condition or take medication regularly.
What do USDA Organic, Ecocert Organic and the laboratory report mean?
USDA Organic and Ecocert Organic are two organic certification marks shown on the current packs. A COA, or Certificate of Analysis, is a generic term often used for batch-analysis documentation. The document published for V6419 is specifically titled Laboratory Report; it identifies the batch, parameters, specifications and recorded outcomes. Organic certification and batch documentation complement one another, but neither replaces the other.
How should you choose between the 360- and 1,000-tablet packs?
The 360-tablet pack is the more practical option for a first trial and lasts approximately 36 days at 10 tablets per day. The 1,000-tablet pack is better suited to customers with an established routine and lasts approximately 100 days at the same intake. To compare spirulina and chlorella first, choose the ENERGYbits® + RECOVERYbits® Value Bundle.

Who’s behind the ENERGYbits® brand
ENERGYbits® was founded by Catharine Arnston after her family’s experience with her sister’s breast cancer (2009). While searching for the most alkaline, nutrient-dense foods, she discovered algae (spirulina, chlorella). She built the brand in Boston and developed it from 2010 onward (sources cite 2010–2011). Her mission: to deliver pure, single-ingredient algae in mini-tablets as a convenient source of nutrients for energy, recovery, and longevity.
Arnston holds a BA (Queen’s University) and an MBA (Ivey Business School, Western University); later she returned to study nutrition and gained experience as a health coach focused on algae science, giving talks and appearing on podcasts. At ENERGYbits® she serves as Founder/CEO (often also Chief Scientific Officer) and has long popularized algae as highly concentrated “bits of food.”
Brand Vision
The vision of ENERGYbits® is to make algae a familiar, trusted whole food for everyday energy, recovery, and longevity—helping people feel, look, and live better—naturally.
That’s why the brand focuses on single-ingredient tablets of spirulina and chlorella, along with rigorous transparency and education for both the public and professionals, so the benefits of algae become widely known and easy to use.
The vision also includes safety and sustainability: cultivation in tightly controlled conditions with triple-filtered spring water and two-step testing (first at the grower and then in an independent FDA-approved lab in the U.S.) to verify purity and nutritional profile.
Algae are viewed as a sustainable resource with a low environmental footprint and long-term benefits for people and the planet.
Brand Mission
The mission of ENERGYbits® is to make algae an easy, trustworthy whole food—so it’s “quick and simple” to add safe, clean, nutrient-dense nutrition to everyday life.
The brand wants people to feel, look, and live better—naturally, therefore it emphasizes education, inspiration, and empowerment on how to use algae in practice.
This mission is grounded in integrity and science: single-ingredient algae tablets, free of fillers and additives, grown and processed with a focus on purity, safety, and sustainability—to benefit people and the planet.
ENERGYbits® therefore communicates origin and testing transparently and has long built trust in algae as “bits of whole food.”
What are spirulina and chlorella and what are their benefits
Spirulina is a blue-green cyanobacterium and chlorella is a single-celled green freshwater alga—both are highly nutrient-dense whole-food sources of protein, vitamins, minerals, and pigments (e.g., chlorophyll, phycocyanin) and other bioactive compounds.
Spirulina has traditionally been cultivated and used as a food; its composition (a high proportion of protein and antioxidants) is well described in scientific reviews and FAO materials.
Chlorella is valued especially for its micronutrients and chlorophyll; its effects may be partly influenced by an individual’s gut microbiome.
What benefits can you expect? Scholarly work describes antioxidant and immunomodulatory activity for both spirulina and chlorella and, nutritionally, notable protein along with selected vitamins and minerals. For spirulina, meta-analyses and newer studies examine potential impacts on body composition and certain cardiometabolic markers; results are promising yet overall mixed and require further high-quality research.
For chlorella, studies suggest potential benefits that can vary among individuals (e.g., depending on gut environment). Practically speaking, both algae can serve as easy-to-use, concentrated food/dietary supplements to enrich the diet, but they should not be regarded as medicines.
Differences & safety: Spirulina is a cyanobacterium (often readily digestible in its “natural” form), whereas chlorella has a rigid cell wall that manufacturers typically mechanically disrupt to improve nutrient availability.
For both, quality can be affected by cultivation practices; scientific sources therefore recommend choosing reputable manufacturers and products with independent testing to rule out contamination (e.g., heavy metals, microcystins).
Dietary supplements should be used with regard to individual circumstances and within the European context of supplement safety; when using them or combining them with medications, a professional consultation is advisable.
Certifications and quality at ENERGYbits®
ENERGYbits® certifications and quality are built on batch-by-batch control “from farm to lab report.” The algae are grown outdoors in freshwater tanks fed with triple-filtered spring water by a long-standing grower in Taiwan with international GMP and ISO 9000 quality standards. Each shipment is first tested by the grower and then re-verified in the United States by an independent, FDA-approved laboratory that confirms purity, safety, and nutritional profile; the brand shares these results long-term with physicians and nutrition professionals.
The tablets themselves are single-ingredient (100% spirulina or 100% chlorella, with no fillers, sugar, or additives), and the chlorella’s cell wall is mechanically disrupted using sound vibration—without heat and without the risk of lead contamination associated with the historic “glass bead” method. This enables high safety and preserves bioactive compounds; independent testing for heavy metals and neurotoxins is standard across all product lines.

Natural benefits of spirulina and chlorella (specifics)
Spirulina and chlorella rank among the most concentrated whole-food sources: they naturally deliver complete plant proteins, chlorophyll, vitamins, minerals, and protective antioxidants (for spirulina, especially phycocyanin). ENERGYbits® offers them as single-ingredient mini-tablets (“bits of nutrition”) without fillers, sugar, or additives—purely 100% spirulina or 100% chlorella that the body readily recognizes as food.
What exactly makes a difference in practice
The tablets are grown in outdoor freshwater tanks supplied with triple-filtered mountain spring water, and every batch is independently tested in the U.S. in an FDA-approved laboratory for purity, safety, and nutritional profile.
Chlorella has its cell wall mechanically disrupted by sound vibration (no heat and no lead risk historically linked to bead methods) to improve nutrient availability, while spirulina serves as an easily digestible source of protein and pigments.
For a balanced intake of both sets of benefits, the brand offers VITALITYbits® (50% spirulina / 50% chlorella).
What sets ENERGYbits® algae apart
The key is controlled cultivation and two-step testing. The algae are grown outdoors in carefully monitored tanks fed with triple-filtered spring water, and every batch is then independently verified in an FDA-approved U.S. laboratory—to confirm purity, safety, and the stated nutritional profile.
The long-standing supplier adheres to international GMP and ISO 9000 standards, improving quality consistency across batches.
For chlorella, ENERGYbits uses gentle cell-wall disruption via sound vibration (no heat and no lead risk associated with historical methods) so nutrients are more available while preserving their bioactivity.
Combined with a single-ingredient formula (spirulina only or chlorella only), this is a highly transparent and sustainable approach that has earned the trust of experts and athletes.
