Clinical data does not support the benefit claimed regarding the inclusion of free (unesterified) fatty acids in a prostate dietary supplement. Prostavar a product manufactured by Superbalife International and reviewed by Stigwood Reseach Institute contains 106 mg of free fatty acids per capsule. Stigwood Research Institute claims that in the free fatty acid catagory Best Prostate scored 0.661 mg of free fatty acids. Stigwood suggests that more fatty acid content is desired however the literature does not support these claims.
