I asked about ZMA a while back, and I was unsure about taking it because it talks about increasing endo test, but I said I was unsure it it would be ok for me to take it (I’m now 17.) I was suggested valarian root, which I took for about 2 months.
I bought a brand from the vitamin shoppe and when the bottle ran out, I went to the local GNC and bought another bottle. My first bottle worked great for me, I felt better in the morning, remembered my dreams (which I usually dont, so I figured that would be an indication of a deeper, higher quality sleep.)
Anyway, when I take it from this new bottle I dont get the same effect. It takes me longer to fall asleep despite different times taking it in the evening, right before I go to bed, empty or a full stomach. It doesnt work. By the way, both bottles were 1000mg of concentrated valarian root.
Has anyone heard of this happening before? Is it possible to build up a tolerance to it?
My question is, after my long ass story, is would ZMA be ok for me to take?
