Most companies use “proprietary blends” so they don’t have to tell you the amount of each ingredient in their formulas. It’s a shady and sometimes dangerous practice. At Natural Stacks we proudly publish our innovative formulas in an open source format.

Natural Stacks formulas contain ingredients which are carefully selected solely on the basis of quality and purity. We actively seek out the most bioavailable forms of each ingredient, and avoid the cheap synthetic forms used by the majority of supplement companies.

All Natural Stacks products are manufactured under the guidelines of the United States Pharmacopoeia (U.S.P.) and Current Good Manufacturing Practices (c.G.M.P.) in an FDA registered facility that is licenced by the U.S. Department of Health and Human Services.

If for whatever reason you’re unsatisfied with your purchase, our customer service champions will work with you to make it right. We also regularly provide actionable tips on our blog and support in our community forum. Admittedly we’re a little obsessed with helping you #liveoptimal.
