Product Features

FSI Nutrition produces creatine supplements (Creatine Clear and Creatine Edge), muscle building formulas (Herculin MRF 4), aerobic conditioning formula (VO2 Max and Glutamine Edge), joint health supplements (Flexion), and general health supplements (Multi-Vitamin, Neuro Edge).

Effervescent creatine works like this: it enters the blood stream and circulates to the skeletal muscles and is quickly absorbed into the small intestine. It is more effective than creatine monohydrate, which enters the stomach as a solid, causing stomach discomfort and non-absorption. Effervescent creatine absorbs into the small intestine faster, increasing the amount that is absorbed and less stomach pain. In the skeletal muscles, your muscles get tired when peddling a bike, throwing a ball repeatedly, lifting weights, etc. Creatine combines with ions to form phosphocreatine, allowing ADP (adenosine diphosphate) to be converted back into ATP (adenosine triphosphate). ADP builds up when muscles fatigue. Creatine delays muscle fatigue by building up large amounts of ATP in the muscles. Some studies have shown that creatine reduces the body fat of an athlete.

Prices of FSI products range in cost from $8.79-$34.00. $8.79 will purchase a 60-capsule box of VO2 Max, designed to increase the body’s aerobic capacity. $17.99 will buy 30 servings of Flexion, designed to promote flexibility and joint lubrication. $29.99 will get you 20 packets of Herculin MRF-4, designed to build lean muscle. $31.96 will buy a small box of Creatine Clear. This is good for anyone with a regular workout routine. $34.00 will purchase a small box of Creatine Edge Effervescent.
