ENERGYbits® Spirulina Tablets nutrition • recovery • energy • immunity • B vitamins
Struggling with ongoing fatigue, a low intake of quality protein or looking for a simple, natural way to support immunity, recovery and everyday performance? ENERGYbits® Spirulina are 100% pure pressed tablets made from the microalga Arthrospira platensis – a concentrated source of plant protein, B vitamins, minerals and antioxidants. They are suitable for everyone, but are particularly helpful for older adults and active athletes, and are usually taken in the morning or during the day.
Why we chose ENERGYbits® for PraveBio.cz
ENERGYbits® is a US brand specialising in 100% pure spirulina and chlorella tablets, with no fillers or unnecessary additives. The algae are grown in outdoor freshwater tanks in Taiwan, in natural sunlight and with triple-filtered mountain spring water, then gently dried at low temperature and pressed into tablets. Every batch comes with a Certificate of Analysis (COA) for heavy metals and other contaminants, and the supplements are certified organic under USDA Organic and Ecocert. Together this provides a tightly controlled, premium supplement rather than a generic low-grade product.
Pure Spirulina Tablets ENERGYbits®
ENERGYbits Spirulina contains 100% pure pressed tablets of blue-green Arthrospira platensis. Spirulina is among the most comprehensive natural sources of nutrients, offering a high content of proteins, B vitamins (especially B2, B3, and B6), natural iron, magnesium, and a range of antioxidants. Therefore, it is often referred to as one of the best available forms of concentrated nutrition.
It also contains a unique blue pigment phycocyanin, which is studied for its antioxidant and cell-protective properties. Spirulina naturally contributes to normal energy metabolism and mental activity, as it is rich in B-complex vitamins and minerals needed for daily vitality.
It is also valued for its content of essential amino acids, which play a role in tissue regeneration and overall nutritional status. Additionally, spirulina contains an intense mix of carotenoids, chlorophyll, and protective bioactive substances that help neutralize free radicals.
Did you know?
Spirulina and chlorella are among the most researched freshwater microalgae. Their combination provides a broader spectrum of natural nutrients:
- Spirulina – blue-green cyanobacteria with a high content of proteins, B vitamins, and protective pigment phycocyanin.
- Chlorella – green algae with a high content of chlorophyll, fiber, and iron.
- Combination of both – offers a comprehensive profile of vitamins, minerals, amino acids, and antioxidants from natural sources.

BEAUTYbits®
VITALITYbits®
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.
