Comments about Nature's Way Phosphatidyl-Serine, 500mg, Softgels, 60 ea:
This is only 100mg P-Serine with 400mg per softgel of other ingredients "complexed" with the P-Serine. When the product arrives you find that 80% of the 500mg per softgel is stabilizer "complexed" with the 20% actual P-Serine. Drugstore.com was previously always trustworthy, but now I learned that one must carefully study every page that may be attached to a product, no more quick, trusting, purchases. If the word "complex" is found anywhere on any page, you don't know what you're getting.
Bottom Line No, I would not recommend this to a friend
