In an effort to ensure that our customers receive only top quality and authentic products, we carry stringent quality checks from the time when the products enter our warehouse till the time the products get packed and shipped to you. At Sixteen Inches, we strive to provide 100% authentic products to our customers by maintaining tight quality control during sourcing and distribution of supplements.

We invest an enormous amount of time and effort to ensure we source products directly from the brands or their authorized importers. The chances of fake products increase as one moves towards resellers.
A shocking new study has found many supplements on the market are fake, with researchers determining more than one-third of 44 products tested don’t contain what’s on the label. But one of the nation’s top holistic doctors notes most supplements do not pose a risk and that there are steps consumers can take to protect themselves from bogus products.
