Phosphatydlserine problem

I starting taking this stuff about 1 1/2 weeks ago,and i am getting cramps in my feet and hands alot.I know that low cortisol levels will cause this but i read that PS won't lower cortisol any lower than natural levels.I haven't been training for a few months now,i was just taking it because i'm not sleeping much.I thought it might be helpful.I won't name the company these tabs are from,but they claim to have 550mg in each tab,of pure PS.I've been taking 2 tabs before bed and 2 when i wake up in the morning.I know it's usually 100mg per tab,of PS,and the rest a PS complex,but they say that all 500mg is 100% PS.Does anyone have an answer for me? THANKS

bump for vets

Looked at PS several years ago and nobody was sure that they worked and also they were expensive as hell. I don't know if the price has come down lately.

You might want to try L-Tryptophan for a sleep aid. Proven to work or do what I do- just eat alot of turkey before bed.

LOL

I'm not taking it for sleep.Thanks anyway
