I saw an article you had written and mentioned phosphatidyl serine as a supplement to help memory. I was taking 100 mg. of phosphatidyl serine from the Vitamin Shoppe. After one month I noticed a great difference in my ability to recall information. I decided to try the 300 mg. but this time I purchased from GNC. Not only did the 300 mg. not help any more than the other dose and brand I was taking but it also didn’t seem to help at all! I’m wondering if there are better brands of this nutrient than others? Both brands I took said it was Soy based from lecithin. Is there a brand that you would recommend over another? Also, I was interested in purchasing the progesterone cream but why is the notice printed that it has been known to cause cancer? Should I be worried about that? Is there anything I can read regarding the research or reasoning behind why natural progesterone could cause cancer? Thank you so much for taking the time!
