Pure Blend of Spirulina and Chlorella Tablets VITALITYbits®
VITALITYbits® Spirulina + Chlorella is a comprehensive food based on pure freshwater algae, combining blue-green spirulina and green chlorella in an ideal 50:50 ratio. It is 100% pressed microalgae without fillers and other additives; each batch is laboratory tested for contaminants and heavy metals and is certified with a COA.
The product is intended for anyone looking for a reliable daily foundation to support everyday vitality, energy, immunity, and regular physical and mental performance. Spirulina contributes to normal energy metabolism and performance, while chlorella is valued for digestive comfort and support of natural cleansing processes.
The recommended daily dose for adults is usually 10–30 tablets per day depending on the goal and individual needs. For children and pets, 2–5 tablets per day are commonly used according to weight and age; always adjust the dosage individually. During pregnancy, breastfeeding, or medication use, consult the suitability of use with a doctor.
The combination of spirulina and chlorella in one tablet provides a nutritional spectrum of more than 40 bioactive substances including essential amino acids, omega fatty acids, RNA/DNA, glutathione, and enzymes like superoxide dismutase (SOD).
Scientific studies describe the antioxidant and immunomodulatory effects of spirulina and the binding ability of chlorella to heavy metals, which contributes to its popularity among users focusing on natural body cleansing.
Did you know?
A balanced diet often does not provide all the necessary nutrients. Spirulina and chlorella complement each other:
- Spirulina – a blue-green cyanobacterium high in protein and iron, rich in B vitamins. Traditionally used to support energy and vitality.
- Chlorella – a green algae high in chlorophyll and fiber, studied for its nutritional properties and ability to bind toxic metals. In EnergyBits® brand, its cell wall is mechanically disrupted for better digestibility.
- Combination of both – combines the benefits of spirulina and chlorella, thus complementing the spectrum of vitamins, minerals, and amino acids.
Sources and Literature
- Nutritional profile of spirulina and chlorella – review articles on microalgae in human nutrition confirm that spirulina and chlorella are well-documented sources of plant proteins, B vitamins, minerals, and antioxidants. This is detailed, for example, in a review on chlorella as a dietary supplement (Nutrients, 2020) and in a comprehensive article on spirulina and brain health (Mar. Drugs, 2021).
- Clinical studies with spirulina – a randomized, double-blind, placebo-controlled study in healthy men observed the effect of 3 g/day spirulina on indicators of mental and physical fatigue and energy expenditure (Int. J. Food Sci. Nutr., 2016). Other systematic reviews and meta-analyses evaluate the effects of spirulina on lipid profile and other cardiometabolic indicators in various populations (Diabetes Metab. Syndr. Obes., 2018).
- Immune response and cardiovascular risk factors in chlorella – an 8-week randomized, placebo-controlled study (5 g/day chlorella) in healthy adults recorded changes in NK cell activity and selected cytokines (Nutrition Journal, 2012). Meta-analyses also evaluate the effect of chlorella supplementation on cardiovascular risk factors, such as lipid levels and blood pressure (Clin. Nutr., 2018).
The information provided is based on peer-reviewed scientific literature on spirulina and chlorella and serves to better understand the topic.

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.
Who are the experts at ENERGYbits®
Catharine Arnston – Founder, CEO & Chief Scientific Officer
Founder and principal “scientific voice”
- Leads research and education about algae (spirulina, chlorella), appears on hundreds of podcasts, and authors expert-focused materials (e.g., SOD & mitochondria).
- Education as listed in company materials: BA, MBA, PhD; also a board-certified health coach. Role: product strategy leadership, scientific content, and public education.
Internal Nutritionist (Team Nutritionist)
- ENERGYbits provides access to a team nutrition specialist for partners/affiliates (product guidance, dosing, education).
- This is an internal role delivering professional support and materials.
Collaborating experts (external guests)
- Andrea Donsky — nutritionist & menopause researcher (external collaboration)
- A nutritionist and menopause researcher featured by ENERGYbits in interviews and educational content about spirulina and chlorella (perimenopause/menopause). She is not part of the internal team, but a recurring expert guest and collaborating voice.
- Dr. Steven Gundry — physician and podcaster (external appearance)
- A retired cardiothoracic surgeon and author who hosted an educational episode with ENERGYbits on superfoods and algae. Not an internal advisor, but a prominent expert platform where the brand presented its data and arguments.
- Dave Asprey — “The Human Upgrade” (external appearance)
- The Bulletproof founder and podcast host whose episode with Catharine Arnston covered algae, mitochondrial health, and longevity. Again, publicity and education rather than membership in the internal team.
ENERGYbits® is led by Catharine Arnston; the tablets are single-ingredient (100% spirulina or 100% chlorella) with no fillers, sugar, or additives. The algae are cultivated in Taiwan in outdoor freshwater tanks with triple-filtered spring water, and every batch undergoes two-step testing, including verification in the USA by an FDA-approved laboratory.
For chlorella, a gentle cell-wall disruption via sound vibration is used (no heat/no glass beads) to improve nutrient availability.
The core idea of ENERGYbits® is to provide pure, single-ingredient spirulina and chlorella tablets as an easy-to-use whole food, with transparently laboratory-verified purity and safety.
