Works superb

Posted by LuckyCharm on Dec 01, 2016

ZMA has been the wonder medicine for me for years now. I use it to speed up recovery after a hard workout, and also to help me get tired in the evening and to help me sleep without waking up several times at night. Use this in combination with Gold Standard 100% Casein from Optimum Nutrition, to get full advantage.

Super Sleep - a must after a hard workout

Posted by MattCHK on Nov 25, 2016

Recommended by my trainer, works like a charm. ZMA is great for anyone working out hard who needs help to switch off at night naturally and have a deep restful sleep to rebuild torn muscles and heal tired achy joints.

I live in England and I was extremely disappointed this morning when I received a txt message from DHL informing me that need to pay an extra £19.00 importation charge on the purchase I made from iherb . I immediately checked on your website to see if I had missed a warning of some sort about this Extra payment. I had not. There is nothing on the website that's informs the customer that they will be charged an extra payment upon delivery, I find this extremely frustrating and wish to make everyone aware so they do not make the same mistake as I have. Had I been aware that I would be held responsible for an extra payment of £19:00 I would NOT have purchased the items in the first place. I feel as though I have been conned by I herb and fully intend on investigating this to see if this is indeed the case. A very disappointed customer who will NOT be purchasing from iherb again CM Lockett
