BulkSupplements.com Phosphatidylserine Powder - Phosphatidylserine Supplement, Sourced from Soy Beans - 300mg per Serving (60mg of Phosphatidylserine), 500g (1.1 lbs) (Pack of 1)

Phosphatidylserine Serine is such a clean effective herb for my brain health. I can think and remember things so much better. I will always order this supplement from this excellent company. Excellent seller. A+

Phosphatidylserine is a phospholipid that protects the cells in your brain. This fatty substance transmits messages in your brain to help your memory and cognitive function. It is is essential for maintaining cognitive function and has been studied for its potential in improving memory, learning, and concentration. Supplementation with Phosphatidylserine have shown promise in enhancing cognitive performance in the elderly and individuals with cognitive decline

This is a light yellow dense and somewhat sticky powder that dissolves in hot drinks and cold with a little extra stirring. The product itself is pure, concentrated and available in this very cost effective way. I feel like it goes to work right away, clears the brain fog.

I got this to help with sleep. It seems to work most when not taking it for a while. Then the effect wares off. I'm not sure if I like the soy source of where this comes from but the price was the second point at first.

Took around 2 months to see my short term memory improve. It doesn't dissolve into liquid well, at all and needs to be stored in an extra sealed bag otherwise it'll start to moisten and clump up.

Since according to the label 100mg of this contains 20mg of phosphatidylserine it might better be called phosphatidylserine 20%.According to several sources (wikipedia.com, webmd.com, examine.com) the typical dose is 300mg/day in 3 servings to prevent cognitive decline. For this product that translates to 1500mg/day in 3 servings of 500mg. Likewise the number of 100mg phosphatidylserine servings in 100g of 20% phosphatidylserine is reduced to 250.Note also that the sources mentioned and the Mayo Clinic suggest phosphatidylserine supplementation is of limited effectiveness and more so for plant-derived vs bovine, which appears to be off market due to possibility of prion infection (Mad Cow).I've noticed no effects from taking phosphatidylserine for several years and plan to replace it with soy or sunflower lecithin in tablespoon amounts in shakes since it makes them smoother and better tasting and is high in a spectrum of nutritious phosphatides.

This is a good product just like all the others I have tried. By now I must have used about 15 Bulk Supplement products and am happy with them all. They have no fillers, reasonable cost, and they usually test well on me (by my chiropractor).

Unfortunately didn’t work for me. Soy triggered my allergies.
