Workout Supplement Sure2Endure ™: A Product That Adds Muscle to Your Workout
by William Shoemaker, M.D. and Leslie Jacobs, M.D.
Sure2Endure is a mixture of herbs, vitamins and minerals formulated to enhance physical performance during periods of aerobic and anaerobic activity and to subsequently aid in the restorative process following exercise.
Sure2Endure utilizes the ergogenic herb, Ciwujia, for its many amazing properties that improve exercise performance. The root of this northeastern Chinese plant delays exhaustion and also decreases lactic acid buildup within the body. (Lactic acid is a by-product of prolonged physical activity and is the cause for the aches, pains and cramps associated with muscle fatigue.) Ciwujia also causes a shift in energy usage within muscle cells so that more energy is created from fat than from carbohydrates. Studies have shown the resulting increased metabolism can reach levels as high as 22 percent energy from fat stores] with lower intensity exercise, 30 percent in exercise of longer duration, and up to 43 percent in high-intensity activities.

In conjunction with the amazing properties of Ciwujia, Sure2Endure is formulated with an extensive list of vitamins which benefit the body in many ways during exercise. The B vitamins maximize metabolism and promote energy production. Thiamine (vitamin B1) is required for the metabolism of carbohydrates to produce ATP (the body's source of energy), thereby providing more energy to muscle cells. Riboflavin (vitamin B2) enhances energy production through stimulation of the mitochondria within the muscle cells. Pyridoxine (vitamin B6) stimulates the enzyme glycogen phosphorylase which breaks down muscle glycogen into glucose and is later converted to ATP. Cyanocobalamin (vitamin B12) is especially important in athletes because it promotes proper formation of red blood cells, which in turn transport oxygen to the muscle for aerobic metabolism. Without adequate amounts of these vitamins present in the body, energy production can be dramatically reduced.
Other vitamins are included in Sure2Endure for their protective effect on muscle cells and the body in general. Just as combustion or oxidation of any fuel can produce toxic by-products, the increased amount of oxygen utilized during exercise and the resulting oxidative process produces harmful free radicals in the body. These molecules randomly cause injury to muscle cell walls and also oxidize fatty acids into another type of free radical, peroxylradicals. The result is an inflammatory reaction within the muscles that can cause discomfort for days following an intense workout. Antioxidant vitamins C and E help to neutralize free radicals, which can limit the resulting muscular pain that occurs during and after exercise. Aspartate salts of potassium and magnesium have been included to decrease the level of ammonia, another toxic metabolite produced with exercise that might otherwise contribute to muscle fatigue. Bromelain, glucosamine and Boswellian also aid in recovery through their ability to stabilize and enhance connective tissue.
In addition to the vitamin content of Sure2Endure, three important minerals have been added to specifically meet the needs of an active body. Each is essential for proper metabolic function and is required in higher concentrations in athletes due to excessive losses through perspiration. Magnesium, for instance, is a catalyst for hundreds of chemical reactions within the body. Aiding in the production of ATP from carbohydrates, it is also necessary for proper muscle contraction. Deficiency of this all-important mineral leads to muscle cramps and early fatigue which obviously limit performance. Potassium, likewise, is essential for proper functioning of both the muscles and the nervous system. Chromium, a mineral in which 90 percent of the American population is deficient, has well-documented benefits upon carbohydrate metabolism. Perhaps the most important of which is an increase in lean muscle mass resulting in a subsequent decrease in body fat. Because exercise causes increased excretion of chromium, athletes are at an even greater risk for problems associated with low levels of chromium. Furthermore, insulin works more efficiently in the presence of chromium, which subsequently increases the delivery of glucose to the cells and ultimately leads to increased energy production.
Each packet of Sure2Endure contains three tablets. For best results, adults should take one packet one hour prior to exercise or physical activity. To maximize this effect, take Sure2Endure with BioLean II ® or BioLean Free.
