In a market saturated with unsubstantiated claims, Spirulysat® is the only liquid spirulina extract concentrated in phycocyanin whose antioxidant action has been validated by a double-blind, placebo-controlled human clinical study. A world first. Conducted by Algosource.
The real state of evidence in the sector
Phycocyanin extracts are all the rage. This blue pigment concentrated from spirulina is presented by dozens of brands as a revolutionary active ingredient: anti-cancer, anti-inflammatory, antioxidant, anti-aging... Promises accumulate on their liquid extracts, their purified powders, their concentrated capsules. The evidence, however, is lacking. Because product effectiveness is not a matter of opinion. It's a matter of rigor and scientific method.
When a brand claims that its phycocyanin-concentrated extract is "clinically proven" or "scientifically validated," ask yourself a simple question: proven how? On which product, specifically?
Many phycocyanin dietary supplements display spectacular claims — anti-cancer, immunostimulant, anti-inflammatory — without any human clinical studies having been conducted on their own extracts. Data published on phycocyanin in general does not constitute proof for a given extract. This is not science applied to a product. It's marketing dressed up as science.
What Spirulysat® has actually demonstrated
Algosource did not wait for others to provide the evidence for it. Our team initiated a rigorous clinical study on Spirulysat® — our liquid spirulina extract obtained by gentle aqueous extraction, without chemical solvents, concentrated in active phycocyanin. Here's what the study measured.
This clinical study was conducted on 40 adults with metabolic syndrome, i.e., a set of imbalances such as excess abdominal fat, high blood sugar or fat levels, and/or high blood pressure, which can increase the risk of cardiovascular disease and diabetes.
For 12 weeks, participants received either a daily dose of Spirulysat® 20 mg or a placebo, as part of a rigorous scientific protocol (randomized, controlled, double-blind study).
The results observed in people who took Spirulysat® show several positive effects on certain health markers. Researchers noted a decrease in urinary isoprostanes, which are indicators of oxidative stress and cellular aging. This suggests better protection of the body against oxidative aggressions.
The study also highlighted a decrease in plasma triglycerides, i.e., fats circulating in the blood when present in excess. Finally, an increase in HDL cholesterol — often called "good cholesterol" — was observed, which is generally considered favorable for cardiovascular health.
Overall, these results suggest that Spirulysat® could contribute to improving certain parameters related to metabolic balance and cardiovascular health.
This is the only randomized double-blind, placebo-controlled human clinical study ever conducted on a liquid spirulina extract concentrated in phycocyanin. Worldwide. No equivalent.
An in vitro study tells you what happens in a test tube. A human clinical study tells you what happens in a body. These are not the same results. This is not the same level of evidence.
Why this level of proof changes everything
The microalgae extract sector suffers from a structural problem: claims multiply much faster than evidence. It's easy to appropriate scientific data published on phycocyanin in general, apply it to one's own extract, and use it as a commercial argument. This is what most market players do.What Algosource does is fundamentally different. By conducting a study on Spirulysat® itself — on humans, with a double-blind, placebo-controlled protocol — the brand does not appropriate the results of others. It produces its own data, on its own extract. It takes responsibility for the demonstration.
Spirulysat®: an extract for those who demand proof
Today there are many phycocyanin extracts on the market. Some are well formulated, some display impressive concentrations. But only one thing distinguishes Spirulysat® in an absolute and irrefutable way: it has been tested as an extract. On humans. With the most rigorous evaluation protocol available in nutraceuticals.
If you are looking for a phycocyanin extract because you have seen promising advertisements, you have a wealth of choices. If you are looking for an extract whose antioxidant efficacy has been truly demonstrated, the choice is much simpler.
Conclusion
Oxidative stress is one of the best documented mechanisms of cellular aging and modern metabolic imbalances. Faced with this challenge, Spirulysat® provides a scientifically based answer — not a promise on a generic active ingredient, but proof on a specific extract. The only one internationally for a liquid extract of this type.
