The Active Ingredient Is: Soy Protein Isolate

Soy protein isolate is a plant-based protein sourced from soybeans, offering a complete amino acid profile suitable for routine nutritional needs. It is refined to a very high purity level and used as a main protein source in many supplements.

This product uses non-GMO soy protein isolate and utilises a water-based extraction method, with natural minerals and isoflavones found in the soybeans, keeping its whole-food integrity.

What Does Soy Protein Isolate Do?

As a complete protein, it supplies all nine essential amino acids, supporting muscle growth and immune function as part of a balanced diet. It also includes natural isoflavones, which are phytoestrogens in soy.

In nutritional terms, the protein supports normal physiological functions tied to protein turnover and keeping body tissues, in line with EFSA guidance.
