Equazen is a special, natural food supplement with a mix of high-quality, pure fish oil and evening primrose oil. Equazen contains a smart formula with the essential fatty acids EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and GLA (gamma linolenic acid) in the special ratio of EPA 9 : DHA 3 : GLA 1. It is precisely this specific ratio that plays an important role. Years of experience have taught us that.
