Phosphatidyl Serine: Protecting Our Minds and Memories Against the Aging Process


by Nils Osmar – June 6, 2022 – Medical disclaimer

Phosphatidylserine (PS) is a brain nutrient that protects short term memory. It’s also good for mood. You can find PS supplements made from soy, or if you’re avoiding soy, an alternative would be taking one made from sunflower seeds. The brand I take is Jarrow sunflower seed PS.

Taking PS appears to have a protective effect against Alzheimer’s, and to help control and counterbalance spikes in cortisol.

On a personal note, I love phosphatidylserine. I started taking it a few years ago when I was under a lot of stress, and trying to lower cortisol. I was also having some short term memory issues at the time. My memory began improving within a few days of taking it. After several months of taking it, my short term memory issues had been resolved.

How Much to Take

If you decide to take it, how much should you take, and how often?

There’s no one size fits all answer. I can say that when I was having memory issues, I found it helpful to take four 100 mg capsules a day. Those problems cleared up eventually, but I still like taking it daily; I take one 100 mg capsule.

I do find it useful for “repairing” my mind if I’m feeling ragged because I didn’t sleep well the night before. Taking a capsule or two can help me feel and function better in that situation.

When to Take PS

I personally like taking it in the afternoon. If I take it in the morning it tends to make me sleepy because of its cortisol-lowering effects
