Learn More
L-theanine is an amino acid found naturally in green tea. Paired with caffeine at a 2:1 ratio, it produces calm, focused attention without the jitters or crash typical of caffeine alone. Widely studied for its effects on attention, working memory, and stress reactivity.
How To Use
Take one capsule with water in the morning. If you drink coffee, take alongside your first cup. Do not exceed two capsules per day. Avoid within six hours of bedtime.
Third Party Lab Testing
Every batch tested by an independent, accredited laboratory for heavy metals, microbial contaminants, and label accuracy. Current batch lab report available on request.
Ingredients
L-Theanine (200mg), Caffeine Anhydrous (100mg), Vegetable Cellulose (capsule shell). No fillers, no binders, no artificial colors.
The Ratio That Actually Works
For most people, coffee alone is a spike followed by a slump. Adding L-theanine changes the shape of the curve entirely, smoothing the peak and dulling the crash. Two hundred milligrams of L-theanine paired with one hundred of caffeine is not the biggest dose on the market. It is the dose that came out of the human studies most cleanly.
Why 2:1
Ratios of 3:1 and 4:1 exist. They are not better. Above 2:1 the additional L-theanine does not appear to add anything the receptor sites can use, and the extra material just gets cleared. Below 2:1, the calm-focus effect degrades and you get closer to plain caffeine.
What it feels like
Not sedating. Not stimulating in the jangly sense. If it works for you (and it will not work for everyone identically), you should be able to sit down and do something demanding without your attention wandering off, for a considerably longer stretch than you can on coffee alone.
