PS + Bacopa
Bacopa has small attention trials. PS trials disagree.
Grade B: Some human proof
Small, early or mixed results in people.
The grade is for the use people talk about, not for every use. Filed under: Brain support, over the counter.
How it works
Phosphatidylserine is a fat in brain cell walls. Bacopa is an herb long used in Ayurvedic medicine.
How it was given in studies
By mouth. In the trials people swallowed it as a capsule, tablet, powder or drink.
This is what the studies did. It is not a how-to.
What studies saw
A review of nine Bacopa trials found quicker attention and reaction time in trials lasting 12 weeks or more. Phosphatidylserine trials disagree: a large cow-brain trial run by its maker found memory gains in older patients who already had serious thinking problems, and a soy trial in older adults with memory complaints found none. We found no placebo-controlled trial of the two together.
The trade-off
Bacopa often upsets the stomach. Effects take weeks, not hours.
When it showed up, in studies
Bacopa: quicker attention and reaction time after about 12 weeks.
