L-Theanine is a non-essential amino acid in the practical form of capsules. This substance is found in nature mainly in the leaves of green tea. In supplement form, people take it alone or combine it with caffeine, for example in coffee or a supplement. Thanks to the plant-based formula, the capsules are also suitable for vegans.

    I was advised to take glycine together with magnesium bisglycinate and L-theanine to sleep better. The product seems good to me, but at the moment I don’t notice any effect on my sleep.
