Janet, I take the phosphatidylserine every day, I started out on Solaray's brand, it was like magic, it increased concentration and memory. Then when I ran out I purchased Natures Way's brand, the effects were not as dramatic, so I then purchased GNC's brand, well nothing. I went back to Solaray's brand and noticed some of these same advantages, but not like in the beginning. I only take one a day, but even though these supplements are over-priced I would not do without them. It may not be just the Phosphatidylserine, but the combination of other nutrients that Solaray includes, they are: 100 mg. Phosphatidylserine 45 mg. phosphatidylcholine 25 mg. phosphatidylethanolamine 5 mg. phosphatidylinositol fatty acids 85 mg. linoleic acid 10 mg. linolenic acid 15 mg. oleic acid 6 mg. stearic acid 27 mg. Palmitic acid 51 mg. capric acid 120 mg. caprylic acid Minerals 8 mg Phosphorus 3 mg potassium It took two weeks of taking this every day before I noticed anything, but I did see improvements, and I am not as yet suffering from any disease. Perhaps, I was just deficient in one of the above, you think?
