Wise Nutrients Soul Warrior Clean Energy protein powders are made from bio-fermented, sprouted brown rice. The natural process of bio-fermentation ensures the preservation of phytonutrients, antioxidants and amino acids while providing the added benefit of pre-digested, highly absorbable proteins, minerals, vitamins, enzymes and healthy bacteria. It is the least allergenic form of protein available, compared with soy and whey, minimising immune reaction, intestinal upset and that feeling of heaviness some protein powders can cause.
