NutraBio Caffeine & L-Theanine is a daily energy and focus capsule that pairs 150 mg of caffeine with 200 mg of L-Theanine in a single serving. It is formulated for people who want the alertness caffeine provides without the restlessness, the anxious edge, or the crash that usually follows it.‡
The caffeine comes from two sources for a reason. Caffeine Anhydrous USP provides 75 mg for an immediate lift. Infinergy Di-Caffeine Malate, a patented form bonded to malic acid, provides another 75 mg in a buffered form that releases more gradually and is easier on the stomach. Alongside them, a full 200 mg serving of L-Theanine, the amino acid found naturally in green tea, has been studied for its role in supporting alpha wave activity, the state associated with relaxed and focused attention.‡
What you can expect is energy that comes on evenly rather than all at once, focus that holds through a long block of work or a full training session, and a gradual taper instead of a sharp drop. Take one capsule up to two times daily, with or without food.‡
Every ingredient and every milligram is printed on the label. No proprietary blends, no fillers, no sugar, no artificial colors or sweeteners. Third-party tested with results published at CheckMySupps.com.
