The Benefits of L-Theanine: - Derived from green tea - Improves blood flow to the brain. - Improves learning and memory. - Promotes relaxation. - Protects us from the negative effects of stress. - Reduces the negative side effects of caffeine. - Protects our brain and neurons as we age. L-Theanine & Caffeine: One of the most popular combinations of nootropic substances is L-Theanine and caffeine. These compounds work astonishingly well together, optimising each of their strengths and minimising their weaknesses. L-theanine stimulates the dilation of the blood vessels to support the negative hypertensive effects of caffeine. It also promotes mental relaxation to directly oppose the jittery effects of caffeine. It does this while maintaining its ability to promote concentration and wakefulness. How much should I take? The recommended dose is 2 capsules per day. This means that this bottle containing 120 capsules will last 2 months of use. To combine these 2 nootropics, simply take your L-Theanine capsules at the same time as your morning cup of coffee, or alongside a caffeine-containing supplement or capsule.
