Withdrawal from caffeine addiction leads to headaches and fatigue. Dietspotlight.com explains that increased heart rate and high blood pressure from GAKIC can lead to hospitalization. Typical side effects from this supplement include being awake for several hours after taking the substance.
GAKIC contains amino acids, glycine, arginine and alpha-ketoisocaproic acid. According to MrSupplement, the product works by reducing muscle fatigue after intense workouts, whereas the only negative is that the effects of the supplement do not last longer.
BodyBuilding.com reveals that initial studies done on GAKIC stated the effects of the product worked faster than creatine. GAKIC significantly improved muscle performance over a sugar-based substance used as a control in early experiments. The supplement works when muscles engage in acute, intense anaerobic exercises.
A study published in 2000 in Medicine and Science in Sports and Exercise explains 13 subjects were monitored over 23 days. Those taking the supplement had a 28 percent increase in resistance to fatigue versus those who consumed dissolved sugar. The effects of GAKIC were not present 24 hours after taking the amino acids.Learn more about Side Effects
