    I read somewhere on the forum that cortisol and prolactin go together often, so do you think that Theanine can help lower prolactin as well?

    Well, given the studies that it raises dopamine, I would expect it to lower prolactin like all other dopaminergic substances.

    Two last question on theanine, if you have any thoughts on them, please...

    1. Is it likely theanine could increase appetite similar to cypro?

    2. Would it be a bad idea to take aspirin with theanine, as it is with cypro?

    Thanks again.

    Just found your statement again on another thread: "Anything that inhibits serotonin will reduce platelet aggregation." from this thread: https://raypeatforum.com/forum/viewtopi ... 54#p103376

    I don't know the answer to these questions, but there is some evidence that theanine may affect platelet aggregation.

    For some reason a lower dose of theanine (200 mg daily) doesn't have the same cypro-type mental boost that higher doses did, like 800+ mg.

    Peata, have you tested Suntheanine? It is supposed to be higher (close to 100%) in L-theanine while regular ones are much lower. I remember Dr. Best brand (others are available) suntheanine to be more effective than Bluebrainboost's regular kind I'm using now. Though it has been several months since I run out of dr. Best and haven't tested them concurrently.

    Would theanine be a bad option for someone dealing with major stress but has low cortisol?

    I don't think low cortisol is a problem. If anything, I think peat prefers it. I have low cortisol and I take about 300 mg theanine per day without any issues.

    Great, I recently started taking Tauring in the afternoon an in the evening along with Niacinimide to help with sleep. Would it be fine to take in the evening with these other 2?

    I'm not sure to be honest. I know people combine taurine and caffeine or niacinamide and caffeine. On second thought, I think it's perfectly fine. If you look at a can of red bull, it has taurine and niacinamide because they probably have synergistic effects.

    Just wanted to include this picture from the second study. Basically, a human dose of about 1.5g theanine daily for 3 weeks eliminated entirely the cortisol response to stress. As you can see the cortisol level of stressed rats given theanine is the same as the cortisol level of non-stressed rats.

    I've been using this for about 9 months, 200mg/2-3 times a week. It's seemed to have stopped working in the last month.

    I thought it may be helpful to note that a low dose of theanine (25mg+-) caused excitatory effects for me. This motivated me to search this out, and I stumbled upon a PubMed abstract stating just that:

    "...the excitatory effects were shown in the rat i.v. administered 1 and 2 micromol/kg (0.174 and 0.348 mg/kg) b.w. of theanine alone. These results suggested two effects of theanine, depending on its concentration."

    Does theanine specifically lower adrenalin, or do we know? I can't find anything...
