    Tryptophan in Protein Supplements and SSRIs e.g Prozac/Citalopram (quick reply pls)

    Hey, I'm taking Citalopram (Celexa) an SSRI (selective serotonin reuptake inhibitor) and I've just noticed on the ingredients list of this Optimum Nutrtion Casein that 1 serving contains over 400mg of Tryptophan.

    Now taking Tryptophan supplements on SSRIs can potentially be fatal, but I also know that Tryptophan is an amino acid that naturally occurs in food.

    So I'm unsure as to whether taking a high amount of it in a protein supplement is going to be dangerous or not. Can anyone please clarify this?

    Tryptophan is an essential amino acid (ie one you need to eat to not die), and you'll find it in all foods, including chicken, turkey, milk, eggs, all kinds of meats, tuna, etc. Protein powder isn't a tryptophan supplement in that it isn't giving you massive doses of it for no good reason, it's just the makeup of whey protein. I'd probably be careful to not take ten shakes a day if I were you though. Best of luck.

    tryptophan is a precurser to serotonin and thus, more tryptophan = more serotonin right? Well not so much. When amino acids enter the blood stream, they all have to compete to get into the brain, so not many actually make it in. Eating a whole source of protein will result in VERY VERY little tryptophan actually crossing the BBB because tryptophan makes up such a small portion of most proteins. I really wouldn't worry about it. The problem is taking an actual tryptophan supplement which will push a huge amount of tryptophan into your brain because there are no other aminos to compete against it


    cliffs:

    whole source(like whey):
    -tryptophan makes up very small quantity
    -all aminos compete, thus very little tryptophan makes its to the brain

    supplement(pure tryptophan):
    -tryptophan makes up entire quantity
    -high amounts of tryptophan enter the brain because there is no competition
