Human Growth Hormone
Human growth hormone or HGH is a form of hormone that plays an important part in cellular regeneration and body growth. Having a high level of this substance is associated with better muscle mass and strength. Many studies have suggested that supplementing the body with melatonin would aid in increasing HGH levels in men. This effect can be partly explained by the role of melatonin in sleep. Good sleep can directly boost the production of HGH. Nevertheless, further research is needed to understand the exact mechanism and examine whether melatonin would change your brain chemistry. [2]
