Our Story
In 2004, a group of health scientists found a way to deliver healthy, sustained energy to chemotherapy patients.
They developed and patented a powerful blend of antioxidants and essential vitamins that optimizes the body’s natural energy production at the cellular level. Because antioxidant molecules neutralize or "scavenge" free radicals to prevent and slow cell damage in the body, they called the formula FRS after these Free Radical Scavengers.
Studies have since shown that the patented FRS® Healthy Energy® formula works with the body to naturally enhance fitness performance, improve cognitive function and support the immune system. At the core of the patented FRS formula is one of the world’s most powerful antioxidants, quercetin (pronounced: kwur-si-tin) found in foods such as blueberries, apples and red grapes. The FRS formula uses the purest form of quercetin (QU995™). Green tea extract, another important antioxidant, works in synergy with quercetin and seven essential vitamins to maximize absorption and effectiveness.
Thanks to this pioneering research, we can all now benefit from energy products packed with healthy, high-quality ingredients instead of chemicals, sugar and large doses of caffeine to create short-lived energy spikes. Today FRS drinks, concentrates, soft chews and powders provide long-lasting natural energy to athletes, fitness buffs and anyone who wants to champion life.
