They do the trick

Posted by healthydoesit on Aug 27, 2016

My zinc levels were low, so I began taking this supplement to help with the situation. I didn't know much about the brand, but they had good reviews and were inexpensive. Less than halfway through the bottle and my levels were already improved, so I will stick with this one. If my review helped you, please check the yes box below.

very good

Posted by Anaterma on Jan 12, 2016

good to balance testosterone, i'm a female and when using this i get less blemishes, less oily skin etc. i don't fancy the dose thou, usually i cut tabs in half. and i kinda seem to be 'addicted' to it, thou in this case it's just a metaphor, since when i stop using it, usually my skin tend to break out more. i wish my hormonal system got more stable without constant intake of any supplement. also this could be smaller with addition of copper, to prevent gray hair, just imo. but all n all this is perfect, quality and price considering.
