  • Supports healthy mental function

  • Helps maintain cell signaling and integrity in the brain

  • Helps maintain healthy memory and cognitive function

The cells of your brain are sheathed and protected by an outer membrane that is full of an important fatty substance called phosphatidylserine or PS. We don't get PS from food, rather our bodies intuitively make the right amount to keep brain cells healthy—at least during the early to mid- stages of life. Over time production of it declines. PS supplements have been clinically proven to support brain and memory health, and the dosage used in well-documented studies is 300 mg—the precise amount in just one capsule of Swanson Ultra Triple Strength Phosphatidylserine.

Rated 5 out of 5 by from Best Cognitive Supplement Swanson is the only brand that offers Phosphatidylserine in a 300 mg strength that works very effectively for me. With this product my mind works better, I think more clearly, feel less stress, and both my short-term and long-term memory improves. It helps me feel normal again. Thank you!

Rated 5 out of 5 by from I can tell a difference I have been using Swanson's Triple Strength Phosphatidylserine for a long time. I've tried other brands but this one is truly the Only one that has helped my mental clarity.

Rated 5 out of 5 by from Great buy ! Review all the multiple companies recommending this as potential brain health. Check their prices & mg amounts. Then come check out Swanson. It does so help make us olders days much easier. Not perfect yet but better.

Rated 5 out of 5 by from My Preferred Brand This is another Great Quality Supplement from Swanson. I also have to commend Swanson for their easy to "Open and Use" supplement bottles. Most people overlook this important feature in their reviews, but I really appreciate the safety and convenience of the foil seals Swanson uses. With many other brands, it's a royal pain struggling to remove those thick paper seals that leave behind an unsealable ring on the bottle top (which sheds bits of itself with use). Swanson's foil seals are easy to cut out and leave behind a nice clean foil ring that easily seals the bottle again when the top is put back on. I highly recommend this product.

Rated 5 out of 5 by from Really Works! My sister recommended this product because I was having a lot of brain fog. After using this product I was amazed at how much better I felt and how much shaper my memory seemed to be. I ran out once and discovered that felt like I did before taking the supplement. Needless to say I placed an order right away and within three days felt great again. I have recommended this product to many other friends and family. It's terrific!

Rated 2 out of 5 by from Apparently not for me Finishing my 2nd bottle and I haven't noticed any improvement. I never take more than 1 per day and some days I forget, so I could possibly get better results with 2 a day or more, but I just can't afford these caps. Too expensive for me. Don't get me wrong, I am ecstatic with 90% of what I get from Swanson and I order a heck of a lot. I am a super satisfied customer overall.

Rated 5 out of 5 by from Effective I had been taking a 100mg dose of PS from a different supplier but switched to Swanson's 300mg dose because the price was the same for this higher dose as I was paying for the lower one. I'm glad that I made the switch, because I feel like the higher dose imparts even more memory support and mental clarity, and it has a calming effect on my mood.

Rated 2 out of 5 by from Not sure if it did anything Really can't say if this product did real change in mood, mental alertness, etc.

Rated 4 out of 5 by from The only PS worth buying PS usually has distorted marketing that confuses the actual PS content among other lecithin components, but this one is accurately labeled and is currently the most PS you can get at this price. It is still quite expensive at therapeutic dosages, but if you need it, this is the one to get. Also, don't get the gelcap version in MCT/sunflower, it's inferior.

Rated 5 out of 5 by from more focused I heard about PS300 over a year ago and have been taking 1 daily since then. It has helped me to be more focused. My 90 year old mom takes it daily, and i have noticed a big difference in her motivation and memory. I am very satisfied.

Rated 5 out of 5 by from serine without anything else added!!! I was very excited to see this product as it is difficult to find in stores serine alone that is not mixed with other supplements. Moreover, I could not find such a high dose at such a low price anywhere else. Thank you Swansons!!!

Rated 5 out of 5 by from Wonderfully Effective Improved my mother's memory & focus (she's 89). I began taking it, as does my sister & we are in our 60ies. Our memory's & focus have greatly improved. It has also helped with my mood swings. Excellent product. Great service. Competitive pricing.

Rated 2 out of 5 by from Couldn't tell a Difference Maybe I didn't use this long enough or maybe I was expecting too much, but I didn't notice any difference. May try again some time in the future but will probably choose different brand.

Rated 5 out of 5 by from Improved Memory and Productivity My 86 year old Mom has had trouble remembering daily conversations and had a lack of motivation. I started with 100mg twice a day and then increased the dosage to 300mg once a day at breakfast. Her days are more productive and her ability to remember events and conversations has improved immensely. This product has helped make a positive difference in her daily activities.

Rated 5 out of 5 by from PS Awesome supplement! One of my favorite. No side effects . Besides that it increased my memory capability it also improved my overall mood. Perfect for PMS symptoms , since I started to take PS I have very little to mild PMS symptoms and no cramps while menstruating. Highly recommended.

Rated 4 out of 5 by from Remarkable Value This is an excellent price for a supplement that generally sells for much more, like maybe 50% more. Because it does what it does quietly, it is hard to tell just how well it actually does work, but I feel that my mental sharpness and memory is doing better because of this supplement. As a 68 year old, these cognitive capabilities are becoming increasingly important to me.
Date published: 2010-07-03
Rated 5 out of 5 by from Good stuff I started taking this when I had noticed failure to remember things and one too many senior "moments". I actually noted effects with 100mg, but 300 is what the studies mostly show. I could tell a difference in about 4 days. It works. Much better retention and no more big "space-outs" like I had.

Rated 5 out of 5 by from Very Valuable Supplement Since I'm well over 50, I've certainly noticed some memory loss. Phosphatidylserine has helped enormously with achieving better cognitive function and information recall. My mind is sharper and I can remember more details, useful in the office work I do each day. This product provides the recommended dose and is priced lower than any other on the market.

Rated 5 out of 5 by from PS I read a couple of articles lately on PS from a couple different sources so decided I would give it a try. searched a variety of sites to find the product and pricing. Yikes, Swanson had best pricing...dosage and BEST of ALL I think it helps

Rated 4 out of 5 by from Results Up, Price Up, Too Bought this for mother-in-law for memory issues.(600 mg, twice daily) She was sleeping into the afternoon and sometimes the evening. After about 6 weeks, have noticed change in sleeping. She is up before noon many days and seems to have more interest in life activities. UNFORTUNATELY, right after I ordered 10 bottles, the price spiked from 15 to 20 dollars. OUCH. That gets expensive. Hopefully, this will be the last increase for a while.

Rated 5 out of 5 by from Triple-Strength Phosphatidylserine My husband and I have both noticed more effective brain function using this product. We have more energy and are more productive. I can remember small details for longer periods of time and keep a train of thought going.
