Double Wood Phosphatidylserine 300mg | Memory, Focus & Cortisol Support, 120 Capsules
Phosphatidylserine (PS) is a phospholipid that makes up a critical part of every brain cell membrane. It plays a central role in cell-to-cell communication, neurotransmitter signaling, and the maintenance of cognitive function as we age. The FDA has recognized a qualified health claim for phosphatidylserine and cognitive dysfunction — one of the very few supplements to receive this distinction. Double Wood Phosphatidylserine delivers the clinically studied 300mg daily dose, making it Amazon's Overall Pick with over 6,100 five-star reviews.
What the Research Shows
Multiple double-blind, placebo-controlled clinical trials have demonstrated that phosphatidylserine supplementation significantly improves memory recall, attention, and processing speed in healthy adults. PS also plays a role in regulating cortisol — the stress hormone that, when chronically elevated, damages the hippocampus and impairs memory formation.
