Why did you choose this product over others?: This is a high quality and strong dose of L-theanine. The dose is far too strong and potent for me but some people might find that to be a good thing. It is very sedating. If I use it I need to break it in half. It's so strong that I don't use it very often but it's good to have on hand just in case.
