Your body's hormone production is far more sophisticated than a simple assembly line. The term "mother hormone" stems from pregnenolone's role as the starting point for this complex hormone cascade. Understanding how hormones work in your body can feel overwhelming, especially when navigating the world of supplements.
DHEA supplementation should be guided by lab testing — supplementing without confirmed deficiency can worsen hormonal balance. Starting doses should be lower — typically 5–10 mg for women versus 25–50 mg for men — and women should monitor for androgenic side effects including acne, oily skin, increased facial hair, and mood irritability. The two conditions share many symptoms — fatigue, sleep disruption, mood changes, irregular cycles, and brain fog — making them difficult to distinguish without lab testing. Breathing exercises that calm the adrenals activate the parasympathetic nervous system within minutes, providing immediate cortisol-lowering effects. Every blood sugar crash triggers a cortisol surge as the body attempts to maintain glucose levels.
Which means if an individual is not feeling good and they have average DHEA/adrenal hormone levels, it’s critical to look elsewhere for the root cause of their problems. From this, people will wrongly conclude that TOT shuts down the production of pregnenolone and DHEA throughout the entire body. Some individuals will require 5 mg of pregnenolone per day and others will require 200 mg  due to factors such as body weight, testosterone dose, root cause of deficiency, etc. "For example, a variation (rs6971) in the gene TSPO can influence internal production of pregnenolone (i.e. decrease production), meaning you may need to take a supplement to elevate pregnenolone levels to normal" If you are considering undergoing TRT and are worried about your precursor hormone levels, adding HCG into the mix will help to keep your pregnenolone, progesterone, and DHEA levels consistent. This leads to a decrease in both DHEA and sex- hormone binding globulin (SHBG), two very important hormones for sexual health and libido.
Supplementing with pregnenolone during TRT can help ensure your body maintains the right balance of sex hormones supporting physical and mental health. While TRT focuses on raising testosterone levels, sometimes it can disrupt the body’s natural production of other hormones, including pregnenolone. Its benefits extend from maintaining hormonal balance and mitigating the effects of aging, to supporting cognitive health and immune function.
When you introduce supplemental pregnenolone, your body may respond by reducing its own natural production. This is why simply adding more of a hormone precursor doesn't always translate to higher levels of downstream hormones. The effectiveness appears to depend heavily on individual factors like age, baseline hormone levels, and overall health status.
The truth is balancing your hormones for both men and women help you lead a healthier life. As with many hormones, pregnenolone production declines with age. However, for some men and women, testosterone levels become abnormally low, leading to serious health concerns.
