Our story

The liquid form, the result of research and the signature of AlgoSource

AlgoSource is an independent French company, founded over 30 years ago on the Guérande peninsula in the Pays de la Loire region. From its inception, the company has been built on a strong scientific conviction: for a natural active ingredient to fully express its biological potential, it must be bio-extracted and preserved as close as possible to its original form. This approach has guided our research on spirulina, an exceptional microalga, and more specifically on phycocyanin, its naturally antioxidant blue pigment involved in supporting the immune system. After many years of research, our teams have shown that not drying phycocyanin and keeping it in liquid form is essential to preserving its native molecular structure, which is directly responsible for its biological activity. This choice is therefore not a marketing ploy: it is the result of in-depth scientific work and is the basis for the clinical benefits observed in our human trials.

Today, the liquid form constitutes the DNA of AlgoSource . Whether it is phycocyanin, magnesium, or formulas combining vitamins (such as B6, B12 or C), type 2 collagen or plant extracts, it reflects the same vision: to make accessible natural, simple solutions whose effectiveness is proven to improve our quality of life.

Our commitments

Acting responsibly, from living beings to humans

Preserving life through a sustainable scientific model

At AlgoSource, responsibility is not an abstract concept: it structures our way of producing, innovating, and planning for the future. We have chosen an industrial and scientific model that respects living organisms, based on the sustainable use of renewable natural resources, such as spirulina and marine magnesium from the Guérande salt marshes.

Our CSR commitment is first and foremost expressed through measured and documented environmental management. AlgoSource is currently the only microalgae company to have conducted and published a complete Life Cycle Assessment (LCA) on a spirulina extract, Spirulysat®. This assessment has allowed us to objectively evaluate its environmental impact at each stage: production, processing, packaging, and use. This approach to transparency is unique in the microalgae-based food supplement market.

Local roots and human responsibility

AlgoSource also acts as a biodiversity ambassador for the Pays de la Loire region, contributing to the preservation of ecosystems and the creation of value within the territory. This responsibility also extends to people : product safety, clear formulations, accessible scientific evidence, and contribution to useful clinical research, including in sensitive areas such as cancer and oncology.

Our vision is simple: to offer natural, effective and responsible nutritional solutions, considering that taking care of health cannot be done without taking care of the environment and people.

R&D and patents

From understanding living organisms to patented innovation

At AlgoSource, research is not about multiplying ingredients, but about gaining a deep understanding of how living organisms function in order to develop simple, natural, and relevant solutions. Our R&D work is based on more than three decades of collaboration with academic laboratories and research centers in France and internationally (GEPEA laboratory and its Algosolis platform, University of Clermont-Ferrand, University of Le Mans, Nantes University Hospital, European Space Agency, Wageningen University & Research, etc.).

This approach has led to the development of patented bio-extraction, stabilization, and formulation technologies, specifically designed to preserve the integrity of sensitive active ingredients such as phycocyanin from spirulina or the
Marine magnesium is naturally present in the waters of the Guérande salt marshes. These innovations are based on gentle processes, without chemical solvents, and are currently unique in Europe in the field of liquid nutritional ingredients of natural origin.

AlgoSource's patents are not an end in themselves: they reflect a rare ability to transform complex natural resources into reliable, reproducible, and scientifically controlled ingredients. This R&D excellence forms the foundation of our entire product range, whether it focuses on immunity, antioxidant activity, metabolism, or joint comfort.

Our clinical trials

Demonstrate rather than promise

AlgoSource distinguishes itself through a scientific commitment based on experimental evidence.

Where the market often limits itself to bibliographic data or marketing promises, our work is based on evaluations conducted according to the standards of scientific and medical research, from in vitro tests to clinical studies in humans.

Research conducted in particular with the Western Human Nutrition Research Centre has made it possible to precisely document the biological mechanisms of our liquid spirulina extract, in particular on oxidative stress, metabolism and certain processes involved in cardiovascular diseases.

AlgoSource is currently the only player to have entered clinical trials on humans using liquid spirulina extracts concentrated in phycocyanin.

The SPIROX clinical trial demonstrated, for the first time in humans, the antioxidant efficacy of our extract, beyond just cellular or animal models, with significant effects on key markers of metabolic syndrome.

The PROPERTY trial, meanwhile, is exploring, for the first time, the potential of a liquid spirulina extract in oncology, particularly for the prevention of chemotherapy-induced neuropathy, a major adverse effect. By combining objective performance comparisons with high-level clinical trials, AlgoSource builds its credibility on measured, published, and reproducible results.

our certificates

Recognized standards for total trust

AlgoSource's scientific rigor is based on recognized industrial and regulatory standards, guaranteeing quality, safety, and traceability at every stage. Our sites and processes are certified:

ISO 9001 and ISO 14001,
apply the HACCP and GMP principles
Some products are certified organic.
a territorial anchoring valued by the Produit en Bretagne label, which recognizes local know-how, controlled production and a sustainable contribution to the regional economic fabric.

Before being placed on the market, each batch undergoes a systematic double quality control check, first carried out internally and then by an independent external laboratory. These certifications concretely reflect our commitment: to offer liquid spirulina and magnesium extracts produced with rigor, transparency, and consistency, enabling informed and confident choices.
