Für deine Schlafstörungen empfehle ich noch Tryptophan.
Empfehlungen: Diese Produkte solltest Du probieren
There are plenty of fly-by-night products around(pretty much all of the ones in local stores) that only offer a very subpar purity. Often times such supplements(like ones sold at WalMart) only contain 20 or less HCA- even when they are marked as higher(this was the conclusion of a recent study).
Such low-grade products(like the ones from GNC usually) are basically scams, replete with fillers and additives and dont do much to give you the true benefits of the natural extract.
