Lecithin and Phosphatidylserine

[Gene Haywo]

I supplement with both soy lecithin and phosphatidylserine
(PS) each of which have well known health benefits. I
understand that lecithin contains some PS and was wondering
how much. How many milligrams of PS would be contained in say
100 grams of granulated soy lecithin, for instance? Anybody
have any data on this?

Depends on the variety of soy, but is not more than ~0.5
mg/100mg. Most often expressed as trace, or ignored altogether
in percentile composition breakdowns.

Thanks Larry, but did you mean 0.5 mg per 100 mg or per 100
grams? Obviously it makes a huge difference. If your figures
as stated are correct, it would mean that 100 grams of
lecithin could yield 500 mg of PS (a substantial amount egual
to 2 to 5 days worth of supplementation of PS). Lecithin is
cheap whereas PS in isolated capsule form is expensive.

PS is normally produced by the body as long as there is no
choline deficiency. Lecithin provides phosphatidyl choline
from which PS is made in one step by reaction involving
serine, which is a non-essential amino acid.

I meant the proportion, 0.5% by weight, to be seen as an upper
bound. Some references show 0% phosphatidyl serine. I cannot
conceive of consuming 100 grams of lecithin granules, but to
each his own.

I don't know of a good way to boost PS levels by supplement
intervention without using a PS supplement. As far as I know,
PS supps are synthesized from soya lecithin, which is why they
are expensive. If extraction was possible, I'm sure they'd
just do that.
