What is L-theanine?
Theanine is a non-dietary amino acid present in foods such as green tea and black tea leaves.
Theanine not only provides a great synergy with caffeine, it also stands on its own as a mood supplement.
Start with one 200mg capsule and only increase to two capsules if needed. Do not exceed 2 capsules daily.
Common Stacks and Synergies
L-theanine stacks well with caffeine since it reduces the ‘caffeine jitters’ associated with this stimulant. Some enthusiasts also pair l-theanine with their morning coffee.
