Introduction:

Creatine (/ˈkriːətiːn/ or /ˈkriːətɪn/) is an organic compound with the nominal formula (H2N)(HN)CN(CH3)CH2CO2H. It exists in various modifications (tautomers) in solution. Creatine is found in vertebrates where it facilitates recycling of adenosine triphosphate (ATP), primarily in muscle and brain tissue. Creatine is naturally produced, primarily in the kidney and completed in the liver. The three amino acids used in this process are glycine, arginine, and methionine. These amino acids are converted into creatine phosphate and phosphocreatine which is then stored in the skeletal muscles and then used for energy. Creatine is stored in the skeletal muscle of the body and is used during physical activity. Creatine helps to maintain a continuous supply of energy to working muscles by keep production in working muscles '. 'Recycling is achieved by converting adenosine diphosphate (ADP) back to ATP via donation of phosphate groups. Creatine also acts as a buffer.

ALS

Amyotrophic lateral sclerosis (ALS) is marked by the loss of voluntary muscle control from the progressive degeneration of motor neurons with subsequent neuronal loss resulting in paralysis and the cause is still unknown. Researchers have found that creatine benefits in protecting neurons from insufficient energy production. And, when administered it was observed that creatine protected neurons from oxidative damage. The most successful on-going trial of creatine and ALS is the Northeast Amyotrophic Lateral Sclerosis Consortium (NEALS) trial in which they have observed that short-term, creatine may only provide subtle reliefs, however, there may be more beneficial effects through the long term use of creatine in patients with ALS.

Huntington’s Disease

Huntington’s disease possess genetically inherited mutations in the number of cytosine-adenine-guanine (CAG) repeats in the huntingtin gene responsible for producing the huntingtin protein. The huntingtin protein is expressed throughout the central and peripheral nervous systems. It has been observed, there is a reduction in the phosphocreatine and inorganic phosphate ratio in Huntington’s disease patients’ muscle tissue, which may indicate the Huntington mutation’s involvement in dysregulating the phosphocreatine/creatine ratio. Creatine supplementation in trials have been shown to improve motor performance, reduced atrophy of neurons, and Huntington protein aggregates .The most successful on-going trail has been then CREST-E (Creatine Safety, Tolerability, and Efficacy) clinical trial. In this trial, they observed a reduction in brain deterioration rate when patients were supplemented with creatine and that creatine kinase is a potential biomarker for HD.
