Jarrow Formulas Mastic Gum 100 mg - 60 Veggie Caps - Mastic Gum Capsules Supporting Stomach and Duodenal Health - 60 Servings

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.

Works great for leveling your mood and helping you focus

This is the best value for a quality PS supplement I have ever come across. This version is the softgel form, the most bioavailable way to take the supplement with the best absorption. This supplement is fat soluble, so I recommend taking it with fish oil. This is a lifesaver for me, helps me with chronic high cortisol levels and frequent insomnia. I’m simply not the same or my best self without it. As illustrated by the picture, you cannot tell a difference between jarrow PS and another highly priced PS softgel which I used to previously buy until trying this. Needless to say, ill be sticking with jarrow. I don’t like being ripped off and imagine neither do you. Good luck and best wishes to good health! UPDATE: My body is very reactive to certain things, I know I previously recommended taking it with fish oil, however if insomnia is your issue, try just taking the PS in the morning and no fish oil. I experimented a bit more and found that the fish oil causes some insomnia for me. You can find that insomnia is a common side effect of fish oil online. Best of luck!

I hate to give this a 1-star review, since I've used this for years without issue, but my last shipment arrived as a solid clump the first week of December. Like others have noted, this is most-likely an issue with storage temperature at the Amazon warehouse and this product isn't eligible for return. This is a great product if you can find it elsewhere, but you're rolling the dice if you order from Amazon based on my recent experience and that of other reviewers.

The PS-100 I ordered from Amazon came in two days, just as promised. I've begun taking them, but not sure if they're worth it yet or not. They were much cheaper here though than Whole Foods, especially if you use the Subscribe and Save feature. Add free two-day shipping and I can't imagine a better deal out there. Now let's just hope these little guys help my mommy-brain! 1/9/12: Thinking a bit clearer, but not sure if that's because I'm also drastically cutting the sugar out of my diet simultaneously. Mom is going to be in a BAD mood this week! 1/12/12: Massive headache, but pretty sure it's just the lack of sugar. 1/14/12: Forgot to take it the last few days...not sure that's a good sign of my memory improving ;o). 1/16/12: Taking it again; all is well. My sister says I have too much time on my hands...she's right! Decided it's difficult to tell whether it's helping or not, but I'll continue to take regardless...

I dont say this lightly- this is one of the most effective supplements I have EVER taken. I struggle with OVERTRAINING and these *FIX* that. If your cortisol is high this will SIGNIFICANTLY lower it. I will lie awake at night with a racing heart and mind, pop 2-3 of these, and I’m asleep in less than an hour. You can FEEL it work. I cant comment on any effects other than lowering cortisol but man for that these are the best thing in the world.

The description of benefits for this product is suddenly completely wrong! I've taken this for years, and not for duodenal issues?! Also, headline states it's 1000mg and 120 capsules, whereas it's actually 100 mg and 60 caps. 5 stars for the product, and zero stars for the inaccuracies.

Attention erreur ou arnaque ! Contrairement à ce qui est affiché, ce n'est pas la boite 60 gellules qui est envoyée mais la 120 gellules, qui contient du soja. Syndrome des jambes sans repos et insomnie garantis pour certains (dont moi).

Reduces your cortisol.excellent for relaxing and sleeping.
