Phosphatidyl serine

Post by johndela1 »

Anyone heard of Phosphatidyl serine? The article says we don't make it in sufficient quantities and we dont' get it from our diet (sounds ridicoulous to me, like we have a defect). Just was curiousl to see if anyone here knows about this.

Its one of many many substances that are claimed to be required in greater amounts than naturally available, for the purpose of making money by selling them as a supplement (phosphatidylserine is sold as a memory enhancer).
Chicken hearts (0.4%), herring (0.4%) and mackerel (0.5%) are high in phosphatidyl serine. (tuna 0.2%, cod 0.02%)

For memory tests in general (in people with moderate cognitive impairment) supplementation with phosphatidylserine did not produce consistent reports, but in recall of wordlists supplementation did produce consistently modest increases.
Then again, what does that mean? For example; in people with decreased bone mineral density supplementary calcium increases bone mineral density on the short term, but eventually the effect appears to be zero (extra calcium cannot cure a single person with osteoporosis) and are lifetime high calcium intakes associated with a high prevalence of osteoporosis.

In other words:
When we experiment with supplements and find a short term positive effect, the long term effect may be the opposite.
If we need dietary phosphatidylserine, we must assume that nature is not stupid and supplied us with all we need in our natural diet.
Many foods contain phosphatidylserine (a phospho-fatty-amino acid).

that makes sense, specially the part about not assuming short term effects (good) mean long term effects will be the same
