DHEA Supplements and Testosterone: Natural Source of Youthful T-Levels?

DHEA (dehydroepitestosterone) is the most abundant steroid hormone in human circulation. It’s made when the CYP11A1 enzyme converts cholesterol into pregnenolone, which is then converted into DHEA by another enzyme called CYP17. The synthesis of DHEA mainly occurs in the adrenal glands, but also takes place in the gonads and brain.

Once DHEA is made and is “added” to the bodily pool, the body can then convert it into various “more potent” steroid hormones via enzymatic reactions (the two main hormones being testosterone and estrogen).

To make it stupidly simple, DHEA is a precursor hormone that the body converts to more potent sex hormones.

Since DHEA can be converted into testosterone, it would be only natural to assume that DHEA supplements (which are supplements containing synthetic dehydroepitestosterone, aka. the real deal steroid hormone) would also increase testosterone levels…

…But what says the evidence? And how legal/safe is DHEA supplementation anyway?

Should You Take DHEA Supplements?

dhea and testosterone productionDHEA is often sold as “anti-age” supplement, since the natural production of the hormone gradually slows down with rolling years.

NOTE: The age-related decline in natural DHEA synthesis has been theorized to be one of the leading causes of age-related testosterone decline.

Depending on your location, DHEA supplements may or may not be legally obtained. The regulations on the supplements are strict because taking DHEA supplements is basically the same thing as using exogenous steroid hormones – such as testosterone or DHT – even though DHEA has significantly weaker effects than the two and is considered to be virtually risk-free.

More or less you’re still introducing exogenous hormones into the body from an outer source, and partly because of this, many sport leagues have banned the use of DHEA (including WADA).

Enough with the jargon now, what is the evidence behind DHEA supps, do they even work as claimed?

First of, the anti-aging claim. Since DHEA peaks at around 20’s and then starts falling down (commonly being half of what it used to be at peak years when you reach 40, and being only 5% of the peak levels at 80), it’s claimed that adding supplemental DHEA to the regimen of older dudes, would have “youthful” benefits. The science on this is actually promising. In aging animals exogenous DHEA has been shown to significantly increase life-span. And a human study of more than 10,000 men aged over 50 years, it was seen that the lower the subjects DHEA levels, the higher the risk of age-related death was.

When it comes to testosterone, DHEA supplementation may or may not be effective. Even though exogenous DHEA increases serum DHEA levels in both men and women (study, study, study, study), almost all of the science on the ability of supplemental DHEA to increase testosterone comes from studies with menopausal women (study, study, study, study), or middle-aged and older men (study, study, study, study). In younger male subjects, exogenous DHEA is highly unreliable in boosting T and most often does not work at all (study, study, study), this may or may not be caused by the fact that young guys already have very high DHEA levels.

NOTE: There’s evidence that using DHEA supplements can increase serum estrogen levels (study, study, study), this occurrence however, is unreliable and highly dependent on the levels of aromatase enzyme, meaning that it’s more prone to happen in women, and in men who are either obese and/or use a lot of alcohol (both increase aromatase levels).

ALSO NOTE: It’s also worth mentioning that the production of DHEA and the stress hormone cortisol are both triggered by the same hormone (ACTH), and that they are both made from the same “raw material” (cholesterol). Because of this, a person who is under stress and has high cortisol levels, is also likely to have low DHEA, and is likely to be more “reactive” to exogenous DHEA supplementation (which by the way can actually decrease cortisol levels).

Conclusion

DHEA supplementation can increase testosterone levels quite significantly in middle-aged and older men, and in menopausal women. However, these effects are – for some reason – highly unreliable in younger guys.

A person who is under chronic-stress (which likely means that he also has low DHEA levels) is likely to derive more benefits from exogenous DHEA supplementation than a person with less stressful life.

It’s also good to keep in mind that using DHEA supplements means that you’re taking exogenous hormones from an outer source. Whether this causes or won’t cause a drop in the body’s natural production, is debated. Being a hormone many sport leagues have also banned DHEA supplements (it’s in the WADA list for example).

Depending on your location, you may be able to buy pure DHEA over-the-counter (affiliate link), in some countries though, it can be only attained via prescription. For example: here in Finland DHEA is a prescription drug, but in the United States, you can buy micronized DHEA from any normal supplement store.

    Hey man! It has nothing to do with this post but is creatine helpful in building muscle mass? Or what are its benefits? Should a 15 year old take it? Thanks

    • Yeah, it’s one of the better bodybuilding supplements out there, search for creatine and you’ll find my article about it.

      • Jonathan Sagrero

        Yeah I read it already, great posts and site by the way, keep up the good work! But honestly I got kind of confused, I’m looking to build muscle and strength and don’t know whether protein is better or creatine? Sorry for all the questions Thanks

        • Lsweet

          If you’re looking to build muscle protein is obviously important but you can get that all from food. But the right carbs and fats are more important for your testosterone production. As for creatine I would consult a doctor considering your age. You can get real far with the right foods and a solid exercise routine.

    Hi.

    I have a question. I’ve taken the DMAE in tablet form in high school, and had hair loss. I was a little overweight, but do you think my hair loss could be due to DMAE? I might be producing too much testestoron and then DHT?

    Nice article man,

    I’ve been struggling a lot with not feeling like I used to..like something was off, I gradually became a bit worse which made it harder to pinpoint a source of the problem, but my main problems were…trouble sleeping, negative (any many) thoughts, concentration problems, obsessing over small things, apathy and because of (or with) that low self esteem.

    So I realized I still had a bottle of DHEA I’d never used and figured I would try once. Man, within 15 minutes I started to feel so calm, like I had been chilling in the sun in the summer the whole day (rarely feel so chill in the winter anyways). My body warmed up, my usually cold hands became instantly warm, the music sounded and felt fucking awesome, libido back, my long lost concentration back, alive, finally. So after that experience (3 days ago) I’ve taken about 50mg a day and have also been sleeping well again. However since I’m 23 years old, I feel like I shouldn’t be needing it and worried it will hurt me even further eventually…on the other hand I’m exstatic as there’s never been a supplement that comes close to what this does to me. Do you have any idea if taking this supplement for a while will help heal my body or do you think that it will immediately drop if I stop?

    It’s weird, some posts I’ve found lead me to believe my estrogen is too low…especially since I was also feeling much shittier when using DIM, but looking at me you wouldn’t say that at all. My blood results from a while back were a bit weird though:
    Estradiol: 0.06 nmol/l ( < 0.2 )
    SHBG 50 nmol/l (20-55)
    T: 29.4 nmol/l ( 10 – 35)
    FT: 59.1 (30-150)

    You have any advice on this by any chance? 😛
