Caffeine is well known for its stimulating effects and mental boosting properties. L-Theanine is the calming amino acid found in Green Tea, which boosts Alpha brain waves and which users claim put them in the 'zone' were work and learning seems to flow. However, unlike Green Tea, these tablets contain the ideal ratio of caffeine to L-Theanine in a 1:2 ratio, that is 100 mg of caffeine with 200 mg of L-Theanine.
The caffeine / L-Theanine combination is starting to become well recognised on internet boards for its positive effects on reducing the jitters & anxiety associated with caffeine, giving the user a calm, clean focus. Other users have found it ideal for social occasions, making them relaxed, with a improved mood and alertness.
