Youthful energy levels – It's a fact: as we age, our cellular energy levels decline—mainly because our mitochondria, the powerhouse of our cells, aren't functioning the way they did when we were younger. L-Carnitine is an amino acid produced in your body that plays an important role in supporting the optimal functioning of your mitochondria—so you can reclaim that youthful energy.
Keep that metabolism going – As we age, levels of carnitine decline in all of our tissues, which affects metabolic activity in addition to our cellular energy. Boosting carnitine levels with L-Carnitine can help you maintain youthful metabolic activity.
Anti-aging must-have – In addition to supporting cellular energy and metabolic activity, L-Carnitine also helps you support already-healthy blood pressure, maintain a healthy body fat composition and promote your brain cell defenses against age-related memory and cognitive decline. It’s the perfect way to show that age really is just a number!
Why our lipoic acid is “super” - Most supplements use a 50/50 ratio of the active “R” form of lipoic acid, which means it’s challenging for your body to absorb it fully. But based on numerous studies, we’ve developed Super R-Lipoic Acid which includes a highly bioavailable form of lipoic acid. The biologically active “R” form of lipoic acid reaches higher blood concentration sooner than standard R-lipoic acid. This gives your body more of this nutrient to use, and more time to use it so that you
Keep the energy flowing - The highly bioavailable “R” form of lipoic acid in Super R-Lipoic Acid has remarkable antioxidant properties.

High bioavailability, rapid intake - Bioavailability is the time it takes for an ingested supplement to reach the bloodstream—as well as how much of it gets absorbed. The more bioavailable a supplement is, the more beneficial it is. Our innovative Super R-Lipoic Acid formula has up to 30 times the bioavailable levels of standard R-lipoic formulas. It’s designed to ensure rapid uptake from the plasma into the tissues—all in an easy-to-swallow capsule.
Ingredients matter - Sourced using only the finest raw ingredients with the purity and potency your body deserves. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.
