L Theanine Side Effects

The most common L theanine side effects are similar to other caffeine and stimulant side effects, which are generally mild. Occasionally, people can experience headaches and dizziness. There are also occasional gastrointestinal symptoms like stomach aches or indigestion, but these are quite rare in nature. It is worth noting that the German Federal Institute for Risk Assessment objected using isolated theanine in beverages. However, this seems to tie more to a lack of research than any significant findings of harm or danger.

As far as interactions with other drugs or ingredients, none have been substantially reported. It lacks toxicities and tends to evade the habit-forming qualities of substances such as caffeine. Due to its herbal basis, L theanine is unlikely to cause the kinds of adverse reactions that synthetic or artifical chemicals with similar aims can carry.

For the most part, L theanine is a safe and effective nootropic property that can deliver some real brain benefits. Try it out as a caffeine alternative for energy and see how it works out for you.
