Every ingredient in a REN formula is selected based on human clinical research not trends, not marketing claims. We use compounds that have demonstrated measurable physiological effects in peer-reviewed studies, at doses shown to be effective in real-world conditions.

All REN products are completely free from added sugars, glucose syrups, maltodextrin, and artificial sweeteners. We formulate without anything that disrupts blood sugar, insulin signalling, or metabolic health because functional nutrition should support your physiology, not work against it.

We don’t use cheap bulking agents, flow enhancers, artificial colours, or flavouring systems that serve no biological purpose. Every component in a REN product has a functional role if it doesn’t contribute to efficacy, stability, or absorption, it doesn’t make the formula.

Most supplements are underdosed. REN formulas are built at clinically relevant, therapeutic levels meaning the quantities used match those shown in studies to produce real biological outcomes, not just label appeal.
