Pregnenolone Unit Converter

Pregnenolone is a steroid hormone synthesized from cholesterol. Often called the "mother hormone," it serves as the precursor to virtually all other steroid hormones in the body, including cortisol, DHEA, progesterone, estrogen, testosterone, and aldosterone.

Beyond its role as a hormone precursor, pregnenolone functions as a neurosteroid in the brain. It is synthesized locally in the central nervous system and plays important roles in memory, learning, and mood regulation.

Pregnenolone levels naturally decline with age, dropping more than 60% after age 30. This decline may contribute to age-related changes in hormonal balance, cognitive function, and overall well-being.

Pregnenolone is produced primarily in the adrenal glands, gonads (testes in men, ovaries in women), and brain. It is synthesized from cholesterol through the action of the enzyme CYP11A1 (cytochrome P450 side-chain cleavage enzyme).
