Jarrow FormulasPS100 Phosphatidylserine 100 mg, Dietary Supplement for Brain Health and Cognition Support, 60 Softgels, 20-60 Day Supply

IMPORTANT NOTE: BUY THE KIND IN THE WHITE BOTTLE, NOT THE BLACK ONE.Amazon recently intermixed the reviews for two different PS (phosphatidylserine) products. Both are made by Jarrow, and Amazon sells both of them. I can see why Amazon was confused, because the labels are virtually identical. However, the products are NOT equally effective. Combining the reviews has confused a lot of people, and has also resulted in some people ordering the wrong product. (I did it myself recently, and had to call Amazon to cancel the mistaken order.) The labels look the same, and the reviews are intermixed, but the product inside is very different.The only way to tell them apart is from the color of the bottle.The Jarrow PS100 in the BLACK BOTTLE is NOT the one I am recommending. It's from genetically modified soybeans. The capsules are large and hard to swallow. They contain a brown powder which is not very effective. I have to take three or four of them to get the same effect as the other product, described below.The Jarrow PS100 in the WHITE BOTTLE is made from sunflowers, not soybeans. It is NOT genetically modified. The gel caps are small and easy to swallow. The product is easy to absorb, and very potent. This is the product I am recommending below.WHY I TAKE PS* I started taking PS a few months ago, when I was dealing with high stress and had high cortisol levels, making it difficult for me to relax and unwind.* Taking it made an almost immediate difference.* Months later, I still find that when I'm stressed, I still find that PS relaxes me. I feel like it calms my mind without sedating me.* When I take it, I feel better; I sleep better, and my short term memory seems better.* When I miss a day or two, I start noticing the same old short term memory problems: I'll go into the kitchen, then forget what I went in there for. When I take it, this seems much more rare. It's not that the PS caused the problems; I was experiencing them before the PS; it's that the PS seems to make my memory sharper and clearer, on days when I take it.* When I take PS at night, I tend to wake up the next morning feeling more refreshed than usual.* It's one of the few supplements I consider essential.WHAT I LIKE ABOUT THIS FORMULA:* This formula (in the blue/gold container) is made from sunflowers, not soy (so, no GM residues.)* It comes in soft gels, not capsules. They are smaller and easier to swallow than capsules.* I feel the effects sooner when I take the soft gels, than when I take Jarrow's other PS formula (or other companies' products) in gelatin capsules.* Because it's so more effective, I need less of it to get a beneficial effect. So the gelcaps are more economical also, in the long run.CAVEATS AND CAUTIONS* On Jarrow's website and elsewhere on the web, it says that this product (in the gel caps) should be kept REFRIGERATED after opening, to prevent it from spoiling. I wish this was made clearer in the Amazon ads. People who buy a bottle and stick it in a warm cupboard for a couple of months are probably taking a lower potency product as a result.* PS (of whatever type or brand) is most effective when taken with a source of DHA. PS was originally found in cows' brains, where it's naturally conjugated with DHA, and the lab studies that showed how much it helped with memory, were done with that type. But then due to fears about mad cow disease, it stopped being sold in that form. Unfortunately, most PS supplements, including this one, do NOT add in the DHA. My recommendation is to take a gelcap of PS with a capsule of fish oil or krill oil, both of which are high in DHA. Or you could take it along with a product like Conjugated Phosphatidylserine with DHA (my second favorite PS product). I like taking the Jarrow and Swanson products together for maximum benefit.• Though normal amounts shouldn't have this effect, taking a large amount of PS may make you sleepy. For a while I got into taking several PS capsules a day... we're talking 7 or 8 caps of PS ... and found myself feeling "dozy" during the daytime hours and needing to lie down a lot. This improved when I cut back on the dose. My current approach (which is working better) is to take a gelcap in the morning with a little fish or krill oil, then take a couple of gelcaps at night (when it may possibly help you get a good night's sleep).IN SUM:Great product, highly recommended. Just make sure that if you're buying Jarrow's PS, that you get the kind in gel caps, not the powdered stuff.

I feel like my memory and focus have improved with using PS100. Brain fog seems to be disappearing! Caps are easy to swallow. I have not had an issue with them sticking together in the bottle, but I store them in a cool, dry cabinet.

After over a year of extremely high stress passed, about 6 months into the "calm," we discovered we were having difficulty thinking clearly, making decisions, remembering short-term, etc. We are only in our 30's and in otherwise good health so this was concerning. A friend had been reading a book about brain fog titled Why Isn't My Brain Working?: A Revolutionary Understanding of Brain Decline and Effective Strategies to Recover Your Brain's Health and recommended this supplement (not by brand, but by type of supplement) for us to take along with high-quality Omega-3 fish oils and stabilizing our blood sugar by omitting sugar, omitting (at least for now) simple carbs like potatoes and white rice, and eating increased amount and frequency of protein. The first time I took them I was extremely relieved as I started thinking almost like normal. I take them 2x a day, morning and afternoon, with 2 fish oil pills each time. I am diligent with dietary changes (never thought I could be that motivated, but when you can't think clearly, it gets your attention!) and have continued to see improvement. These may not work for everyone, as each body is different, but they have been very beneficial for me. I use the Soy-Free, Non-GMO ones that come in the white bottle. The reviews on this product are mixed between people using the same product as I described, and another soy-containing product which is in a black bottle. I haven't tried the black bottle formula.

I bought this Jarrow PS100 supplement for elderly person in February 2025, guess what, bottle expiration date is March 2025.Maybe you could take the gels in one month but for elderly person is high risk to provide old medicines and supplements.Just be careful

Like others my pills arrived in one stuck together glob. I tried peeling them apart, but that really didn’t work. What did work? I put the bottle in the refrigerator for at least one hour. Took it out and shook it up. The result, a nice rattle from individual pills. Needed to encourage a few to separate with little effort. So far they’ve stayed separate.

Firstly, wow. Where do I start... I'll start with an example of what this supplement did for me. As I age, I notice my typing ability falling off when I am word-smithing/composing say an important document like a contract attachment or similar document that has monetary impact. When thinking about what one wants to convey, the last thing one needs is to make erroneous keystrokes on every other word; it's distracting, and it then causes one to refocus on what one is typing rather than the important content one is trying to convey, and worse yet, it's frustrating. After taking this, I noticed immediately that whatever I was thinking came flying off my fingertips with a lot fewer typographical errors and at much greater speed. It seemed like if I thought it, I could compose it instantly without having to type slowly and disect words so I could just type it.This supplement has really sharpened my ability to think, and that transfers to mind-to-finger dexterity, and general motor skill improve in all things I do. This is a great supplement. I will continue to take it; hell, I'm scared not to take it now!
