USN Cramp Block prevents cramping and buffers lactic acid build-up within the muscles. Cramp block provides your body with the vital minerals Sodium, Magnesium, Calcium and Potassium, which help prevent cramping and general muscle fatigue.
The inclusion of the amino acid Taurine, regulates the absorption of these minerals. Vitamin B6 aids in the maintaining of sodium and potassium balance, as well as promoting red blood cell formation. Cramp Block's advanced formula will improve your body's energy capacity, without the debilitating effects of cramp and lactic acid build up and cramping.

- I used this product during a number of cycling events that I do. I seem to not get any cramps anymore and helps especially during the longer rides or multi day stage events. Although you need to take it for about 3 days prior to the event it is a bit expensive.
