Common Questions

FAQs

We uniquely formulate each supplement using a combination of absorption-enhancing technologies, such as liposomes and advanced nano-delivery systems. We don't rely on a single method. Instead, we select and layer multiple techniques based on the specific ingredient and how the body best absorbs it. This allows us to create pharmaceutical-grade supplements with up to 149× better absorption.
Our Berberine uses FenuMat® technology — a patented delivery system that creates a self-emulsifying hybrid-hydrogel form of berberine. This results in 6.2× more free berberine in your bloodstream compared to standard berberine HCl capsules. It's also gentler on digestion, making it suitable for those who've experienced GI discomfort with other brands.
Yes — our formulas are designed to work synergistically. If you're already taking other supplements, our products are generally safe to stack. We recommend consulting with your healthcare provider if you're on prescription medications, particularly those that affect blood sugar or blood pressure.
Yes. All products are third-party tested by Light Labs (most recently January 2026) and are certified glyphosate residue-free. We test for heavy metals, contaminants, and potency to ensure every batch meets pharmaceutical-grade standards. Our products are also HSA/FSA eligible.
We recommend consulting with your healthcare provider before taking any supplement during pregnancy or while breastfeeding. While our ingredients are high quality and rigorously tested, individual health circumstances vary and professional guidance is always best.
