Life Extension PS Caps

Our verdict

Life Extension PS Caps works out to $0.36 per serving of phosphatidylserine, at 1serving per serving in capsule form. That puts it around the median of the 31 phosphatidylserine products we can price per dose, where the typical serving costs $0.35, a Value Index of 1.0 where the median product is 1.0. One container lasts 100 days at the label dose of 1 serving a day, about $10.80 a month. We could not verify a third-party certification for Life Extension in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
