Product Information

If you would like the peace of mind of having a fully qualified and insured nurse draw your venous blood sample at a location of your choice, we can organise this for you. Please Note: There are different cell-specific enzymes & concentrations to synthesis the varying steroid hormones & no known mechanism that could transfer pregnenolone between the mitochondria of one cell to another, and especially not between the different zones. The newer figures (graphs) now demonstrate three headings of cholesterol with three lots of pregnenolone converting to all downstream hormones in three separate columns. For normal steroid hormone production, cholesterol is converted into pregnenolone in the adrenal glands. Then several enzymes complete the production of multiple hormones, including:

Although prenenolone is the mother hormone (underneath cholesterol) it splits into three regions within the adrenal cortex: Keeping that in mind, I started out on 1/5th of a cap=20mg every other day. Then slowly, stepped it up to 25mg every day.

Preview

It is too soon to report any long term effects. I used to be prescribed artificial testosterone gel. I liked the good effects, but it also caused me a pretty bad temper (unusual for me), much reduced patience, and a libido that was too strong, because it ended up dominating everything. Helps maintain healthy hormone levels Helps maintain mental focus & memory health Supports a healthy mood.

Pregnenolone is a steroidal hormone produced mainly in the adrenal glands, but it can also be made in the liver, skin, brain, gonads, and even in the retina of the eye. Synthesized from cholesterol, it has been called the “grandmother” of all the other steroidal hormones. From pregnenolone, DHEA, progesterone, testosterone, and estrogens are made. Because of this, a pregnenolone supplement is one of the first possible avenues considered by physicians who understand AFS. Pregnenolone tests are one diagnostic tool doctors use on newborns after the more common causes of CAH have been ruled out. Cai HL, Zhou X, Dougherty GG, et al. Pregnenolone-progesterone-allopregnanolone pathway as a potential therapeutic target in first-episode antipsychotic-naïve patients with schizophrenia. Psychoneuroendocrinol. 2018;90:43-51. doi:10.1016/j.psyneuen.2018.02.004 If both 21- and 11-hydroxylase deficiencies have been ruled out (the most common forms of CAH), then analysis of pregnenolone and tests for other precursors may help establish a diagnosis of 3-beta-hydrosteroid dehydrogenase or 17-alpha-hydroxylase or StAR deficiency. When should I get this test?Pregnenolone is best used only under medical supervision so that blood levels can be assessed and an appropriate dose suggested. Most physicians recommend starting with a low dose of 5mg to 10mg, which may be increased to 20mg or 30 mg (occasionally 50mg) if there is no obvious effect. Once benefit is obtained, a lower maintenance dose of 2 mg to 5 mg per day often suffices and prevents accumulation. Regular breaks in treatment – so called hormone holidays – are also recommended. When oral hormones are taken with food, twice as much is absorbed when digested with meals as when taken on an empty stomach. This comprehensive blood test encompasses all of the necessary blood investigations required to make a preliminary diagnosis of testosterone deficiency. In addition to a full hormone panel, it also looks at other general health parameters to help identify any potential reversible causes of low testosterone, and give you a more complete picture of your overall health. Excess DHEA can have masculinizing effects in women with the development of facial hair and a deeper voice (which is irreversible). This is only usually seen in doses greater than 25 mg a day and is most common at doses above 90mg per day. Some doctors feel women should not take DHEA at all. Others feel it is acceptable to take it over the age of 40 as long as androgen levels are being measured regularly.

In the brain, pregnenolone has a protective function. Fatigue can injure brain cells; pregnenolone supplement protects these cells from this kind of damage. Its calming effects can provide protection from the stress that leads to production of cortisol. Conversion is effected by enzyme availability and concentrations, but also external signals coming from outside the adrenal gland. Think of the HPA Axis and because many steroids such as DHEA are neuro-active, meaning they will activate or inhibit neurotransmitter systems and vice versa, its not just about the usage but also our emotional wellbeing, etc. . Teen boys may have poor and/or delayed development of secondary sexual characteristics, such as facial hair or deep voice. Some doctors may also use a pregnenolone test to help diagnose and determine the effectiveness of treatment for memory and neurologic illnesses. There is limited and conflicting evidence for memory enhancement in humans when pregnenolone is given as a supplement or drug.

With 17-alpha-hydroxylase deficiency, pregnenolone and progesterone may be elevated, along with 11-deoxycorticosterone. Other precursors and steroid hormones, if measured, may be low, including:

Some claim that DHEA may extend life span and hail it as the fountain of youth, although as yet there is no robust evidence to support this. DHEA and sex drive After DHEA is released from the adrenal glands, it is modified in the liver by the addition of a sulphate molecule, so most DHEA circulates in the form of DHEA-sulphate (DHEA-s). DHEA-s is generally considered to be less active than DHEA, but it is usually this level which is measured and used to reflect your DHEA status.
