Good for muscle recovery
I didn't really know if this supplement was doing anything for me until I stopped taking it. It does make a difference for me with respect to muscle recovery. I take it every day.

The best ZMA
I have tried other ZMA brands and all of them have produced to me some reactions: Headache, dry mouth....etc. This product is really very good, and it has helped me to sleep and rest. and also to control oily skin. I recommend it !!!

Why are you no longer carrying this product?
A shopper on Apr 18, 2018
BEST ANSWER: To much magnesium in it and where it comes to aspartate it's very absorb able which can induce hypermagnasiyma
Can I take half tablet?
Alex R on Jan 31, 2019
BEST ANSWER: If the question is really, "can I easily cut a tablet in half?" the answer is yes, it has a caulk like consistency & will hold together fairly well.
Is this product additive?
A shopper on Jun 11, 2018
BEST ANSWER: I wouldn't say it's additive, but it does make a difference for me. I stopped taking it & noticed a real difference in muscle recovery.
