Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Phosphatidyl Serine is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from effective, but... At first I was skeptical with all the claims it made about cognitive prowess in regards to memory, recall, and mood. After a week on this stuff I can say that it works! I don't know about other people, though, for me it was like magic. I immediately noticed an improvement in remembering what I read, retained the information longer, and oddly, my mood was more optimistic and calm... consistently. The only con is that it doesn't last for long, so you have to take at least 2 capsules each day to maintain a consistent efficacy, which makes the bottle last about 15 days, since there's only 30 capsules in each bottle. A solution might be to increase the pills to 60 without raising the price too much.

Rated 5 out of 5 by from Memories Like most people who are getting on in age I don't think my memory is what it used to be; but then neither is anything else. And so in the past I have tried a few supplements to hopefully improve my memory, and the only one that has had a noticeable improvement is Phosphatidyl Serine. And it is surprising how much easier life is when you can remember where you left your keys, also it does not bother my sensitive stomach.

Rated 5 out of 5 by from Brain fog gone Love, love, love taking PS, it helps me have more focus and motivation, plus overall I just function and think so much clearer when I take at least 2 a day. Swanson's has the best price for this brand.

Rated 5 out of 5 by from Very effective! These help me relax, quiet my mind, and yet help with memory recall as well. I've already purchased 2 bottles from Swanson and plan to order more. Can't beat the price. Thanks, Swanson!
