## Description

L-Theanine Powder Overview L-theanine powder is a popular dietary supplement ingredient which promotes mood, relaxation, and cognition. Theanine makes for an ideal combination with caffeine supplements or coffee. The optimal ratio of L-theanine to caffeine is 2:1 or 1:1 depending on the individual. Quality This L-theanine is third-party tested in a US lab for guaranteed purity and potency. Freshness guaranteed 2 years from purchase date. L-Theanine Dosage Take either 100 mg or 200 mg as needed. Do not exceed 400 mg daily. The included scoop measures roughly 200 mg.

Review: Reliable seller - Product as described, perfect delivery. Great product
Review: This seems like a very good quality supplement. It has absolutely no smell and very little taste. You can of course taste it a little, as it is a glutamate-derived amino acid. It has a slightly umami taste like MSG, but much less strong and with more earthiness. It dissolves very quickly in water. I typically put it in green tea or dissolve it in a glass of water (in 8 oz, you can't taste it at all). I take 200-400 mg a couple times a day. I lost the scoop pretty much immediately, but I would recommend volumetric dosing anyway: just dissolve a known amount into a known about of water, and take a shot or add it to your drinks. As for whether it works: I dunno. I haven't figured out whether L-theanine is a placebo for me or not, because the effects are subtle, but it does seem to calm me down, or at least make me think I can calm myself down. It works exactly as well as suntheanine capsules have worked for me in the past. I appreciate that this company lab tests (their HPLC results looked good), everything put together it seems very pure and legit.

## Features

- SCOOP INCLUDED: Easily measure the recommended 200mg L theanine powder dosage with the included anti-static 1/8 teaspoon (tsp) scoop.
- MOOD, RELAXATION, COGNITION: L-theanine promotes mood health while enhancing relaxation and cognition. It supports a positive mood, allowing you to enjoy your day to its fullest.
- GOES GREAT WITH CAFFEINE: Eliminate caffeine jitters and increase focus by taking a 2:1 ratio of L-theanine to caffeine. This makes an excellent partner for coffee or caffeine supplements. Add one scoop (theanine 200mg) of theanine supplement to your coffee (about 100mg of caffeine). Or take L-theanine 100 mg with a 50 mg caffeine pill. For caffeine pills, mix a scoop of theanine powder with water or juice, or just have it dry and enjoy its natural slightly sweet, umami taste.
- PURE L-THEANINE: No fillers, additives, artificial colors, or flavors. Just pure L theanine supplement powder packaged in a GMP-compliant facility. FitPowders L-theanine is also gluten-free, non-GMO and vegan.
- SATISFACTION GUARANTEE: Buy with confidence. Contact us if you are unhappy with your order and we will provide a full refund.
