I think the Shute brothers were the first to use this vitamin for heart health and then discovered it to be useful for the sex organs and related structures thereby gaining much publicity for this nutrient. I personally feel sure that the whole complex is better than the fractions, but the Shute brothers got their great results using just the fraction. I think they disagree as to which fraction is the best. Hope I got this right, but it has been years since I read about this. pj
