Cellucor C4 Original 60 Serv. Cosmic Rainbow

One serving of Cellucor C4 Original in the Cosmic Rainbow flavor contains 150 mg of caffeine. One scoop of this variety corresponds to 6.5 g of powder.

Cellucor C4 Original (here in the 60-serving, Cosmic Rainbow version) contains vitamins C, B3, B6, B9 (folic acid), and B12. These contribute to supporting your workout in the following ways:
Vitamin C (ascorbic acid): It contributes to normal energy metabolism and supports the function of the immune system during and after intense physical activity. It also helps protect cells from oxidative stress, which can increase during high levels of physical exertion.
Vitamin B3 (niacin): This vitamin contributes to the reduction of tiredness and fatigue and supports normal energy metabolism. This is crucial for maintaining performance throughout a workout.
Vitamin B6 (pyridoxine): It plays a key role in normal protein and glycogen metabolism. Since glycogen is the storage form of carbohydrates in the muscles, vitamin B6 supports the efficient release of energy during exercise.
Folic acid (vitamin B9): It contributes to normal amino acid synthesis, which is important for the repair and building of muscle tissue, and also helps reduce fatigue.
Vitamin B12 (methylcobalamin): This vitamin contributes to the normal formation of red blood cells, which are responsible for oxygen transport in the body. It also supports normal energy metabolism and the function of the nervous system.
In summary, the vitamin combination in Cellucor C4 Original aims to optimize energy metabolism, delay fatigue, and support the metabolic processes necessary for athletic performance.

The CarnoSyn beta-alanine contained in Cellucor C4 Original plays a key role in improving muscular endurance by increasing the concentration of carnosine in skeletal muscle. Carnosine acts as a buffer against lactic acid, which is produced during intense physical exertion, thus delaying muscle acidification and maintaining performance over a longer period. This allows athletes to complete more repetitions or maintain a high training intensity for longer before fatigue sets in. The often-described tingling sensation under the skin, medically termed paresthesia, is a completely normal and harmless side effect of taking beta-alanine. It is a temporary reaction of the nerve endings that usually occurs shortly after ingestion and subsides after a while without any lasting effects on the body.

Micronized creatine monohydrate supports physical performance by increasing phosphocreatine stores in the muscles, which accelerates the production of ATP (adenosine triphosphate). This enables increased strength and endurance during short, repeated, and high-intensity activities such as sprints or heavy weight training. It also promotes muscle regeneration and can support muscle growth through improved cell hydration and increased training volume.
