Why ENERGYbits® – and why this bundle?
Spirulina and chlorella are widely available, but their quality depends on far more than price per gram. The water source, growing conditions and testing of each batch all matter. ENERGYbits® uses algae cultivated in controlled freshwater tanks in Taiwan, supplied with triple-filtered mountain spring water. The products carry two separate organic certifications – USDA Organic and Ecocert Organic – and, according to the brand, every batch undergoes testing at three separate stages. These smaller packs allow you to discover both signature products from an American brand that has specialised in spirulina and chlorella for over 15 years, without committing to two large 1,000-tablet packs. NUZBOZ s.r.o., the company behind PraveBio.cz, is the exclusive importer and distributor of ENERGYbits® for the Czech Republic and Slovakia. The bundle saves you 10% compared with buying both products separately.
What exactly is included in the ENERGYbits® + RECOVERYbits® bundle?
This is not a pre-mixed blend. Each product remains in its own original pack, so you can take spirulina and chlorella together, separately or at different times of day. Each tablet weighs 250 mg; ten tablets provide 2.5 g of product.
ENERGYbits® Spirulina – 360 tablets
Small pressed tablets made from 100% spirulina, Arthrospira platensis. Spirulina is a blue-green cyanobacterium commonly described as a microalga in food and nutrition. The brand positions it primarily within a morning and daytime routine.
- 90 g / 360 tablets,
- 250 mg per tablet,
- one ingredient only: spirulina,
- no fillers, binders, added sugar, colourings or caffeine,
- USDA Organic and Ecocert Organic displayed on the current retail pack.
RECOVERYbits® Chlorella – 360 tablets
Small pressed tablets made from 100% chlorella, Chlorella vulgaris. Chlorella is a green freshwater microalga with a firm cell wall. According to the brand, the cell wall used in RECOVERYbits® is mechanically broken without heat.
- 90 g / 360 tablets,
- 250 mg per tablet,
- one ingredient only: chlorella,
- broken cell wall,
- no fillers, binders, added sugar, colourings or caffeine,
- USDA Organic and Ecocert Organic displayed on the current retail pack.
Why do ENERGYbits® cost more than ordinary spirulina and chlorella?
The Czech market offers algae powders and tablets across a wide range of price points. With microalgae, however, price per gram is only part of the story. Algae can concentrate substances from the environment in which they grow, which makes the water source, cultivation site, processing method, certification and laboratory results especially important.
Peace of mind for everyday use: certification, traceable origin and batch testing
The current retail packs of ENERGYbits® and RECOVERYbits® display two separate organic certification marks – USDA Organic and Ecocert Organic. The brand also states that the algae are cultivated in controlled freshwater ponds in Taiwan using triple-filtered mountain spring water, without pesticides, then dried at low temperatures and tested at three stages for each batch.
For the batches documented by PraveBio.cz, Certificates of Analysis identify the relevant batch and report selected microbiological parameters, heavy metals and nutritional markers. That is a tangible reason these products are not simply interchangeable with anonymous algae tablets.
USDA Organic + Ecocert Organic
Two separate organic certifications shown on the current retail packs, providing independent verification of organic cultivation and processing standards.
Taiwan and a controlled water source
The brand describes outdoor freshwater ponds supplied with triple-filtered mountain spring water. For microalgae, the quality of the growing environment is one of the defining features of the finished raw material.
A specialist grower
According to ENERGYbits®, the brand has sourced its algae for more than a decade from the same Taiwanese grower, whose experience spans around fifty years. The brand states that its growing partner holds GMP and ISO 9000 certifications and describes ENERGYbits® Spirulina as Non-GMO Certified.
Low-temperature processing
After harvesting, the algae are slowly dried at low temperatures and pressed into small tablets without added fillers or binders, according to the brand.
Three-stage testing
The brand describes testing after harvest, testing of the finished tablets before they leave Taiwan and further independent testing on arrival in the USA.
Batch-specific Certificates of Analysis
PraveBio.cz publishes available laboratory reports showing the batch number, test date and measured results. Each document applies to the batch identified in the report and not automatically to every future batch.
What does “laboratory tested” actually mean? It is not an absolute claim that a natural raw material can never contain trace levels of monitored elements. It means that a specific batch has been analysed and its results compared with defined specifications. With algae, that degree of transparency is far more meaningful than a broad marketing statement unsupported by an accessible report.
The ENERGYbits® story: specialist expertise born from personal experience
From helping her sister to more than fifteen years devoted to algae
Catharine Arnston began researching spirulina and chlorella after her younger sister was diagnosed with breast cancer. While looking into foods that could form part of her sister’s nutritional routine, she discovered algae and gradually chose to leave her long corporate career behind.
Since 2008, she has focused on algae-based nutrition and built the brand around just two raw materials: spirulina and chlorella. ENERGYbits® was therefore not created as an incidental product within a broad vitamin catalogue, but as a highly specialised brand centred on origin, processing and long-term customer education.
That consistent focus has earned ENERGYbits® a strong following, particularly among US biohacking, longevity and endurance circles. The premium price reflects more than weight alone: it also represents a long-standing specialist supply relationship, two organic certifications, batch testing, transparent documentation and a genuinely convenient format.
Spirulina vs chlorella: what is the difference?
| Feature | ENERGYbits® Spirulina | RECOVERYbits® Chlorella |
|---|---|---|
| Raw material | Arthrospira platensis | Chlorella vulgaris |
| Type of organism | blue-green cyanobacterium commonly described as a microalga | green freshwater microalga |
| Characteristic pigment | phycocyanin and chlorophyll | naturally high chlorophyll content |
| Cell wall | does not have the firm cellulose wall associated with chlorella | mechanically broken cell wall, according to the brand |
| Brand-recommended timing | morning, during the day or before activity | after activity or in the evening |
| Format in this bundle | separate 360-tablet pack | separate 360-tablet pack |
Why two separate packs rather than a 50:50 blend?
- you can introduce each product separately,
- you can use different quantities of spirulina and chlorella,
- the two products can be placed at different points in your day,
- you can assess the flavour and individual tolerance of each raw material more easily,
- when travelling, you can take only the product you are currently using.
For spirulina and chlorella together in a single tablet, see VITALITYbits® Spirulina & Chlorella 50:50.
Who is this bundle for?
This bundle is designed for adults seeking a clean, traceable format of spirulina and chlorella, with the flexibility to build both products into a personal daily routine. Its value lies in the combination of convenience, separate dosing, certified organic status, traceable origin and documented quality control.
For busy professionals and creatives
For people who want spirulina to hand in the morning, at the office or before a long work session, without making a green drink or reaching for a shaker.
For athletes and active adults
For runners, cyclists, gym-goers and recreationally active adults who want to place ENERGYbits® before activity and RECOVERYbits® afterwards or in the evening, in line with the brand’s suggested routine.
For biohackers and people who value precise routines
For customers who pay close attention to provenance, certification and batch data, and prefer a format that can be counted tablet by tablet rather than measured out as a powder.
For vegans, vegetarians and clean-label shoppers
For customers looking for two single-ingredient formulas with no fillers, binders, added sugar, colourings or caffeine.
For those who dislike green powders
The tablets can simply be swallowed with water. There is no mixing required, so you can avoid both the taste and texture of a green drink, as well as the mess that comes with preparing one.
For a first introduction to the brand
The 2 × 360-tablet format is a more accessible starting point than buying two large 1,000-tablet packs at once, while still saving 10% compared with purchasing the smaller packs separately.
How and when should the tablets be taken?
The brand places the two products at different points in the day. ENERGYbits® are recommended mainly in the morning, during the day or before physical activity. RECOVERYbits® are recommended after activity or in the evening. This reflects the brand’s suggested routine; it is not a health claim and does not mean the products must be taken exclusively at these times.
ENERGYbits®: the brand’s suggested daily routine
At least 10 tablets a day. The brand also outlines 20- and 30-tablet routines, depending on individual use.
- swallow with water or chew if preferred,
- take with food or on their own,
- new users may begin with 5–10 tablets and increase gradually,
- if you are sensitive to the flavour, swallow rather than chew.
RECOVERYbits®: the brand’s suggested daily routine
10 tablets a day. The brand also outlines 20- and 30-tablet routines. First-time chlorella users are advised to begin with 5–10 tablets and increase the amount gradually over approximately one week.
- most commonly after activity or in the evening,
- swallow with water or chew if preferred,
- take with food or on their own,
- introduce larger quantities gradually.
Example daily routine
| Time of day | Product | Example |
|---|---|---|
| Morning / daytime | ENERGYbits® Spirulina | 10 tablets in the morning, before work or before physical activity |
| After activity / evening | RECOVERYbits® Chlorella | 10 tablets after activity or in the evening |
At 10 tablets of each product per day, each pack lasts approximately 36 days. You do not need to introduce both products at the same time; when trying them for the first time, it may be more practical to add the second product after a few days.
How long does one 360-tablet pack last?
| Daily amount of one product | Weight of daily amount | Approximate duration |
|---|---|---|
| 10 tablets | 2.5 g | 36 days |
| 20 tablets | 5 g | 18 days |
| 30 tablets | 7.5 g | 12 days |
Important: the routines above are based on the brand’s product guidance. Always follow the directions and warnings on the current local-language label supplied with the individual pack.
What do the published laboratory reports show?
PraveBio.cz publishes available Certificates of Analysis for specific batches. The reports include product and batch identification, test dates, selected nutritional parameters, microbiological testing and heavy-metal analysis.

ENERGYbits® is a global brand focused on pure spirulina and chlorella tablets, founded by Catharine Arnston after a personal family experience; the search for the most nutritious alkaline foods led her to algae as concentrated “bits of food” with zero compromises. The brand’s mission is to offer single-ingredient nutrition with no sugar, fillers, or additives, with an emphasis on transparency and scientific validation.
The portfolio includes ENERGYbits® (spirulina), RECOVERYbits® (chlorella), BEAUTYbits® (spirulina), and VITALITYbits® (50/50 mix)—all grown on outdoor freshwater farms using triple-filtered spring water and independently tested in the U.S. in an FDA-approved laboratory to confirm purity, safety, and nutritional profile. The result is a convenient, traceable, and sustainable source of micronutrients for energy, recovery, and everyday care.
Algae-based products renowned for:
- Distinct cultivation & testing – outdoor freshwater farms with triple-filtered spring water; every batch is independently tested in the U.S. (FDA-approved lab) for purity and safety.
- Single-ingredient formula – 100% spirulina or chlorella, no fillers, sugar, or additives, pressed into mini-tablets (“bits of food”).
- Sustainability – algae as a whole-food with a low resource footprint; cultivation designed for ecology and efficiency.
- Transparency & recognition – long-term sharing of laboratory tests and recommendations from experts and athletes.

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.
Why choose ENERGYbits®: quality, purity, verified safety

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.
