FRS uses a scientifically advanced, patented formula developed by health scientists that features the all-natural antioxidants quercetin and green tea extract, plus seven essential vitamins. These powerful ingredients work together at the cellular level to deliver:

  • Long-lasting, natural energy
  • Improved athletic performance
  • Increased mental function
  • Immune system support

Fueled by nature. Endorsed by science.

The FRS formula was originally developed and tested by health scientists as an effective way to deliver natural, sustained energy to chemotherapy patients. Today, the benefits of FRS are enjoyed by athletes, fitness experts, nutritionists and others wanting to lead a healthy lifestyle.

The benefits are clear as seen through these scientific studies:

Reduction in mental fatigue4
Improvement in concentration4
Increase in endurance3
Increase in physical performance1

What’s inside?

Let’s start with quercetin.

Quercetin (kwur-si-tin) is a revolutionary, all-natural antioxidant found in foods such as blueberries and apples. With over 10,000 scientific studies on the benefits of quercetin, scientists believe it works at the cellular level with your body to produce and sustain your own natural energy. Quercetin mimics the effects of exercise by enhancing the production of mitochondria, the energy-producing units in our cells. Until now, exercise was the only practical way to increase mitochondria in cells. Dr. Mark Davis, Ph.D. University of South Carolina and FRS Scientific Advisor says, "Quercetin could be one of the most important discoveries in nutrition in a very long time."

The grade and purity of an ingredient is as critical as the ingredient itself. FRS uses QU995® (99.5% pure quercetin) which aids the speed and amount of absorption. It is recommended to have 500 - 1000mg of quercetin daily. Each serving of FRS contains 250 – 325mg of quercetin, with two to three servings suggested daily.

Mark Davis is a professor of exercise physiology and nutrition in the Department of Exercise Science, Arnold School of Public Health at the University of South Carolina. He is also a fellow in the American College of Sports Medicine where he was previously on the board of trustees. Dr. Davis's research is primarily focused on the effects of exercise and nutrition on mental and physical fatigue and how dietary components like quercetin appear to work in the brain, immune system and muscle to increase mitochondria, reduce inflammation and fatigue and increase resistance to infection and cancer. As an FRS scientific advisor, Mark says "FRS is unique among energy products in that it contains quercetin which provides energy in a totally different way than the ingredients in other energy drinks: it's a healthy choice for energy."

Another antioxidant powerhouse.

Green Tea Extract, like quercetin, is an all-natural antioxidant. Unlike black or oolong tea, green tea is not fermented and is instead typically created by steaming fresh leaves at high temperatures. Because of this process, the antioxidant properties remain intact and health benefits are maximized. Each serving of FRS contains 20 – 85mg of green tea extract.

Completing the formula.

Vitamins are the third and equally important component of the FRS formula. While critical to any complete nutrition program, vitamins cannot be produced by the body but are found naturally in certain foods. Today, diet alone doesn’t usually provide adequate vitamins so dietary supplements, like FRS, have become staples of a balanced diet. FRS not only contains seven essential vitamins, B1, B2, B3, B6, B12, C and E, but each serving provides over 100% of the Recommended Daily Value.

Take the natural approach to energy

Unlike traditional energy drinks that rely on chemicals, sugar and large doses of caffeine to create energy spikes, FRS creates natural energy the healthy way. Although FRS products contain a small amount of caffeine, it is derived from green tea extract and is a mere 20mg to 48mg, which is the equivalent to 1.5 to 4 ounces of coffee. The caffeine in FRS is not the primary source for improved energy and performance but rather acts as a metabolic enhancer to kick-start the patented FRS formula.

Equally as important is what’s NOT inside our products. FRS does not contain preservatives, flavors or synthetic colors.
