I notice that when i take one of those two i tend to have a mild headache even on low doses like 100mg of L Theanine or 400mg of Magnesium(Magnesium Oxide, Magnesium Citrate and Magnesium Aspartate) both from Now.

In my research this is not a common side effect at low doses.

nothing?

Odd, I typically use magnesium to treat and theanine to prevent headaches.

My guess is that this may be to do with nitric oxide. Some people are a little sensitive to nitric oxide and can get headaches when blood vessels reconstrict after dilation. In my opinion, you could take this as a sign of health--an indication that you do not need to take these supplements.

Do you take any other medication or supplements?

[ianmarconi]

Only B1 vitamin and fish oil, but the l-theanine was the first that i try and since the first time it give me a mild headache

Theanine has given me slight headaches before. Magnesium has never caused a headache.

I did notice when I get Suntheanine from NOW I never got headaches from it but with regular theanine I would get a headache.

Are you sure your getting headaches from magnesium or is it that you are taking them taking?

[ianmarconi]

I'm sure because the only thing i take before bed its magnesium and i frequently wake up with mild headache
Today i take ALCAR for the first time and i also had a mild headache!

Do you take your L-theanine with or without caffeine? If you take it without coffee or caffeine, try adding some and see if that helps.

I stop with the caffeine, i am extremely anxious and trying to fix it.

Those two are the only supplements that contain rice flour and rice contain gluten that has been linked with headaches and migraines. I am on a elimination diet to found food sensitivities and gluten is one of them. That explain alot.
