BulkSupplements.com Phosphatidylserine Powder - Phosphatidylserine Supplement for Brain Health - Sourced from Soy Beans, Gluten Free - 500mg (100mg of PS), 20 Servings (10 Grams - 0.35 oz)

It was a small package, but always good product

not enough of a trial to recommend its use

I think mine was exposed to air because it was not in a loose powder form when received. I still used it though

This product smelled horrible when opened, and was undated. I am past the return date and hopefully, the manufacturer will see this and either replace or refund. i have bought other things from them and likely may not continue after this, if they don't do something. i will keep you al up to date.

Very high-quality product at a good price. I'll be buying more from them in the future.

It helps me with brain fog. I am very happy with it.

If you want brain support, get this asap!

I have tried quite a few nootropics after looking them up and researching them. This one has the most pronounced effects of any I have tried. The powder sort of resembles and tastes like leftover tiny crumbs from wheat bread. I bought 10 grams and guestimated about 1/100th of it would be what would fit on the end of a thin steak knife. At that dose (can't be more than 300 miligrams) I most definitely notice a mental effect. I also tend to experience anxiety so I was interested in any calming effects. I like the feeling but am not able to objectively say if it has actually decreased anxiety or not, but I do like the feeling. It seems to good to be true that at this can be taken daily, and I am still experimenting with that, but from what I have read it should be relatively harmless. I can power through a lot of software coding with this stuff and reading is especially nice. Highly recommended.
