Pregnenolone
To produce pregnenolone, thyroid, vitamin A, and cholesterol have to be delivered to the mitochondria in the right proportion and sufficient quantity. Normally, stress is balanced by increased synthesis of pregnenolone, which improves the ability to cope with stress. Lipid peroxidation, resulting from the accumulation of unsaturated fatty acids, iron, and energy deficiency, damages the mitochondrias' ability to produce pregnenolone. When pregnenolone is inadequate, cortisol is over-produced. When progesterone is deficient, estrogen's effect is largely unopposed. […]
Pregnenolone is a lipid produced from cholesterol under the influence of thyroid and Vitamin A, serving as a precursor to progesterone and DHEA . It is the precursor to these hormones and is essential for their production . Pregnenolone inhibits the stress process and blocks the production of cortisol, stabilizing cells .
Pregnenolone is typically produced in sufficient amounts from converting sugar to cholesterol, but when individuals are poisoned with unsaturated oils, heavy metals, or other stressors, supplementing with pregnenolone can be beneficial . This is especially true for individuals with thyroid or Vitamin A deficiencies, as these hormones are necessary for pregnenolone production .
Research has shown that pregnenolone can be effective in treating various conditions, including chronic low back pain, depression, PTSD, and autism . The proposed mechanism for its benefits is the increase in serum levels of neurosteroids like allopregnanolone, which have anesthetic effects .
Pregnenolone has also been shown to be safe and effective in treating chronic low back pain in military veterans, with significant improvements in pain scores and interference scores for work and activity . Additionally, a study found that a single dose of pregnenolone accelerated recovery from intensive physical exertion and delayed fatigue in competitive volleyball players .
It's worth noting that the effectiveness of pregnenolone may depend on individual circumstances, with older individuals potentially experiencing more pronounced effects due to decreased levels of pregnenolone, DHEA, and progesterone with age . A reasonable first dose of pregnenolone is around 0.1 grams, although some individuals may require up to 1 gram per day due to poor absorption .
