Pregnenolone is widely used in the field of medicine and health due to its role as a precursor to various steroid hormones. It is often utilized in hormone replacement therapy to address deficiencies in hormones like progesterone, estrogen, and testosterone. In neurological research, pregnenolone is studied for its potential neuroprotective and cognitive-enhancing effects, particularly in conditions like Alzheimer’s disease and memory impairment. Additionally, it is sometimes included in dietary supplements aimed at improving mood, reducing stress, and enhancing overall vitality. In anti-aging therapies, pregnenolone is valued for its ability to support hormonal balance and combat age-related decline. Its applications also extend to research on inflammation and immune modulation, where its role in steroid hormone synthesis is explored for therapeutic benefits.
