Not for some people! Not for me!

I did not have a good experience using this product. I became sick after using this product. I no longer use the product.

Sam's Club Vitamins.

Best price I could find and it was free shipping with my premium membership. Was delivered within 2 days.

Give them a try

I feel the effect and love these. They were recommended by intermittent fasting group. I am glad I decided to add these my supplement regiment

Tampered product packaging

Seal was still on but wasnt attached, so couldnt tell without removing the cap. Second product in purchases on the same day that was tampered with.

It works for me

I've been using this product for many years for my Charley Horse. It works for me. Talk to a doctor before you try it.

Need magnesium

Most people are lacking in magnesium but don't know it. Keeps everything moving if you know what I mean.
