Great thanks dennis....I really appreciate your response. Not sure what the DMAE is so I will research that one and regarding the yeast I am very apprehensive as we (family of 5) have all suffered badly from candida overgrowth at various stages. I've used the oils when my son was younger but will definitely resume them! Does evening primrose oil have these three?? My other son, daughter and myself function very well on EPO.But will definitely try all (except yeast). This is a very helpful forum!
