Ingredient Traceability

Most supplement companies let their manufacturers source the ingredients in their formulas. The manufacturer's incentive is to increase their margins. They do this by using low-cost commodity grade ingredients from unvetted suppliers. Often times the ingredients are synthetically produced to mimic a natural compound and have not been tested for safety or pharmacological activity.

Not Natural Stacks. We source 100% of our ingredients meaning that we control the entire supply chain. Our ingredients are grown with integrity and consistently processed for maximum potency and bioavailability.

This dedication to the highest quality natural ingredients ensures that our products work exactly as they are designed to with full efficacy. Our meticulous sourcing features the World’s most respected ingredients including Magtein™, BioPQQ®, Quatrefolic®, NovaSOL®, and Quali-C®.

Full Label Disclosure

A proprietary blend does not actually mean that a product is special in any way. Companies use proprietary blends to hide the amount of each ingredient in their formulas.

If a particular ingredient has sound research behind it and a strong customer demand, the price will most likely be higher compared to other ingredients. With a proprietary blend, the company might include only a fraction of the actual effective dose of that ingredient so that they can still include it on their label. We call these “pixie dust” ingredients.

Natural Stacks is different. We disclose the exact amount of every single ingredient and use clinically-proven effective doses of every ingredient.
