Human growth hormone (HGH), produced by the anterior pituitary gland, plays a central role in: Body composition: GH promotes fat breakdown (lipolysis) and supports lean muscle preservation Tissue repair: GH stimulates collagen synthesis, wound healing, and cellular regeneration Sleep quality: GH is primarily released during deep (slow-wave) sleep Bone density: GH works alongside IGF-1 to maintain bone mineral density Immune function: GH supports immune cell proliferation and activity Cognitive function: GH receptors are present throughout the brain Growth hormone production declines approximately 14% per decade after age 30, a process sometimes called somatopause
