DHEA is a steroid precursor to estrogens and androgens, so its use in osteoporosis hinges on its potential to supply the hormones that regulate bone remodeling. In aging and postmenopausal individuals, reduced estrogen accelerates bone loss. DHEA can be converted in peripheral tissues to estrogen and androgen, which can help balance bone formation and resorption, potentially leading to small increases in bone mineral density. Clinical evidence shows only modest and inconsistent benefits, so it remains a proposed, not first-line, option for osteoporosis. It’s not used for conditions like hypertension, pneumonia, or renal calculi because those illnesses aren’t driven by the hormonal pathways that affect bone density.
