200mg of pure L-theanine per capsule, sourced from green tea. Nothing else in the jar. Find Out More
200mg of pure L-theanine per capsule. Nothing else in the jar.
L-theanine is an amino acid found almost exclusively in the tea plant, Camellia sinensis. It is a non-protein amino acid, which means that unlike the amino acids in meat, eggs or pulses, the body does not use it as a building block for protein.
It also isn't present in meaningful amounts in everyday foods. Outside of tea there is very little dietary source for it at all, which is why it is usually taken as a supplement rather than eaten. A brewed cup of green tea contains only a small fraction of the 200mg in one One Nutrition capsule — and drinking enough tea to reach that figure would also mean a considerable amount of caffeine.
Three things are worth checking on any label before you buy:
Most capsules contain more than the active ingredient. Flow agents stop powder sticking to machinery, bulking agents fill space when the active dose is small, and anti-caking agents keep it loose. They serve the manufacturer, not the person taking the capsule. Pure Fill is One Nutrition's standard for capsules made without them — which is why a 200mg dose here fills a capsule that would elsewhere hold 200mg of active plus several hundred milligrams of everything else.
One capsule per day, with or without food. There is no requirement to take it at a particular time of day — take it whenever fits your routine.
How much L-theanine is in a cup of green tea? Considerably less than a capsule. The exact amount varies with the leaf, the grade and how long it's brewed, but it takes a great many cups to approach 200mg — along with all the caffeine that comes with them.
Is pullulan vegan? Yes. Pullulan is a polysaccharide produced by fermentation and contains no animal material. It is an alternative to gelatine capsules, which are not suitable for vegans or vegetarians.
Should I take it with food? It makes no difference. Take it with or without.
Does it contain caffeine? No. L-theanine is extracted from green tea, but the extract is not the leaf — this is L-theanine on its own.
How long does a jar last? 30 capsules at one per day is a one-month supply.
L-theanine (green tea) extract. Capsule shell: pullulan.
Vegans and vegetarians. Free from gluten, soy and dairy.
