“This multi vitamin supplement is now part of my daily routine. Definitely a “top rated multi” and convenient considering I don’t have to buy 10-20 different products when I can get all the regular vitamins and extra in one product. I order 2-3 boxes of Myovite per time and receive it in AUS with no shipping issues at all. Not to mention Strong Supplement Shop is one of the most reliable online supplement retailers I’ve known about for years and have had numerous experience with other products of theirs in the past. I just made my next purchase and will continue to do so in the future. Keep it up guys and appreciate what you do!”

“If you take two packets it only last 22 days but that being said its ingredients panel is far better than all the other vitamins out there. I also like that it has a focus blend on greens instead of fruit complexes. The amino acids are solid the detox blend is solid and it has glucosamine and msm. I wish it had hyrolonic acid in it also but all in all this is a very good vitamin.”
