  • Features Sharp-PS® soybean phospholipid complex

  • Supports cognitive health

  • Triple-strength, high-potency formula

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.

Customer Ratings & Reviews

Rated 4.5 out of 5 by 37 reviewers.
Rated 5 out of 5 by Helping sleep It is a great part of the sleep study that I am patterning after & it is working for me. July 24, 2016
Rated 5 out of 5 by 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! July 16, 2016
Rated 5 out of 5 by Great for the brain and sleep This is great for memory and cognition. It also helps you fall asleep. Swanson's Triple-Strength Phosphatidylserine is super high quality. May 15, 2016
Rated 5 out of 5 by 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. February 13, 2016
Rated 5 out of 5 by 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. August 18, 2014
Rated 5 out of 5 by 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. July 10, 2014
Rated 5 out of 5 by 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! July 6, 2014
Rated 2 out of 5 by 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. January 5, 2014
Rated 5 out of 5 by 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. November 8, 2013
Rated 5 out of 5 by Returning customer Haven't found another product like it. Love the ultra strength and taking only one! Has helped with mental clarity and stress relief. October 28, 2013
Rated 2 out of 5 by Not sure if it did anything Really can't say if this product did real change in mood, mental alertness, etc. July 13, 2013
Rated 4 out of 5 by 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. April 28, 2013
Rated 5 out of 5 by 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. April 24, 2013
Rated 5 out of 5 by 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!!! April 18, 2013
Rated 5 out of 5 by Love this product Really works for me, memory much better, word recall, name recall ,just easier now. April 2, 2013
Rated 5 out of 5 by works for me This product helps me with name and word recall. It's a little pricey, but I feel it's worth it. March 16, 2013
Rated 5 out of 5 by 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. February 14, 2013
Rated 2 out of 5 by 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. January 2, 2013
Rated 5 out of 5 by Great for my family's attention span. PS helped my daughter and I to become more organized and use our time more wisely. September 30, 2012
Rated 5 out of 5 by phosphatidyl-serine I 'm using to help my memory. Seems to be working just fine. September 15, 2012
Rated 5 out of 5 by 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. June 6, 2012
Rated 5 out of 5 by Memory Boost I noticed an improvement in my memory for remembering numbers I was working with several days after I started using Triple Strength Phosphatidylserine. April 12, 2012
Rated 5 out of 5 by PS 300mg PS helps with my memory having reached the age of frequent "senior moments". March 15, 2012
Rated 5 out of 5 by 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. February 21, 2012
Rated 4 out of 5 by Like this a lot Also tried the 100 mg,but think this works better for me October 9, 2011
