Abstract:
Dehydroepiandrosterone(DHEA), an adrenal androgen, has attracted much attention as an anti-aging hormone as well as a marker for senescence because of its unique change along with aging. DHEA is reported to have beneficial effects such as anti-diabetes, anti-obesity, and anti-atherosclerosis. It is also shown that DHEA has anti-osteoporosis effects to increase bone mineral density in randomized controlled trials(RCTs). As osteoblasts express aromatase which will convert androgen to estrogen, DHEA may act protectively against osteoporosis through its metabolites. Because there is no report on fracture risk by DHEA administration, further studies are required to clarify DHEA effects on human bone metabolism.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
