Q: How to measure L-Theanine powder?
A: For accuracy, use a digital milligram scale. A standard dose is 100-200 mg. If you don’t have a scale, a level 1/32 teaspoon (a “smidgen”) is roughly 100 mg. We highly recommend using a scale for precise dosing.
Q: How to take L-Theanine powder?
A: Simply mix your measured dose into any cold or hot beverage like water, tea, coffee, or a smoothie. For a calming effect without drowsiness, take it as needed. For sustained benefits, a common regimen is 100-200 mg, 1-2 times daily.
Q: Does L-Theanine powder have a taste?
A: It has a very mild, slightly sweet or savory (umami) flavor, similar to green tea. It is not bitter and is generally considered easy to take, often enhancing the taste of beverages it’s mixed with.
Q: How to dissolve L-Theanine powder in water? A: L-Theanine dissolves very easily. Simply stir it into your water with a spoon or a frother. It dissolves completely in seconds without leaving any residue, creating a clear solution. No special techniques are required.
It is crucial to consult with a healthcare professional to determine the correct dosage for your specific health status.
