How are we different?

We source our spirulina and chlorella from a small village in Portugal. Our partner farm is one of the largest European producers of sustainable, innovative microalgae products. The company pays particular attention to ecological, social and industrial sustainability and maintains optimised processes in terms of energy efficiency, resource conservation, employee satisfaction and safety.

The spirulina grows in large, open basins with a special culture medium, under conditions that are as close to nature as possible. Harvesting, which starts in March and continues through November, is conducted with sieving machines which carefully filter the single-celled microalgae out of the water. The concentrated spirulina from the sieve is then spray dried, which is a common process used to achieve a dry powder from liquid raw materials. The result is a concentrated, non-sterilised, nutrient-rich organic spirulina powder with a very fine particle size and a mild taste.

The chlorella is cultivated autotrophically and sustainably with natural light: it grows in a closed system using only sunlight, CO₂ and clear water. No artificial fertilisers are used, so the high organic quality of the algae is preserved. Our partner farm in Portugal is a pioneer in the field of modern and sustainable algae cultivation. Their state-of-the-art green technologies form a unique intersection between innovation and sustainability, and they follow the most stringent quality standards.

Spirulina platensis

Spirulina platensis (Arthrospira platensis) is a cyanobacterium originating in Central and East Africa. Now also widespread in Central America, the algae has been in use for hundreds of years in the cuisine of its countries of origin. It is known for its extraordinary nutrient density; in fact, it even serves as a primary food source for some animals, such as flamingos. Depending on the environment and the water quality, spirulina develops different phenotypes and nutrient densities, and it can multiply rapidly given optimal conditions. While spirulina has been traditionally cultivated in the Pacific, where it benefits from its preferred alkaline and salty water, today it is cultivated worldwide in inland, man-made spirulina farms as well as in freshwater.

Chlorella vulgaris

A type of freshwater microalgae, chlorella is one of the oldest life forms on earth. The unicellular eucaryote, only 5–10μm in size, has a spherical shape and an exceptionally high chlorophyll content. Its particularly strong cell walls contain hemicellulose, which offers the cell stability. Chlorella has an extraordinarily fast reproduction rate, with every cell division taking only 16–20 hours. The chlorella growth factor (CGF) contained in the cell nucleus accounts for this high rate. CGF is a unique complex first isolated in the 1950s by Dr. Fujimaki, consisting of nucleic acids, nutrients, amino acids, peptides and polysaccharides. Chlorella's unique nutrient profile, its high protein content and its valuable secondary phytochemicals make it an interesting superfood.
