Bests & Worsts Reviews from Amazon

Just received this product today and it no longer contains Suntheanine. I ordered the same product a month or two ago and it was made with Suntheanine but it seems that they have stopped using it, despite what the product description says. Why this (potentially) matters: Suntheanine is the only L-theanine preparation known to be 100% L-theanine. Other preparations (likely this new formulation) may contain up to 50% D-theanine, a non-psychoactive isomer. Just a heads up from a disappointed customer.
