NutraBio DHEA

100mg of DHEA (dehydroepiandrosterone) per capsule, 60 capsules. Single ingredient, fully disclosed.

⚠ Read this page before buying. DHEA is a hormone precursor rather than a nutrient, and it is treated differently from most things on our shelf. The cautions below are not boilerplate.

What DHEA actually is

DHEA is a hormone produced by your adrenal glands, and it sits upstream of both testosterone and oestrogen in the steroid hormone pathway. Your body converts it into those hormones as needed.

Two things follow from that, and they matter:

DHEA production peaks in your twenties and declines steadily thereafter. By the seventh decade of life, levels are typically a fraction of their peak. That decline is the reason most people take it
Because it converts to both testosterone and oestrogen, you do not fully control which. The ratio depends on your own enzyme activity, body composition and sex — and aromatase activity, which converts androgens to oestrogen, increases with body fat

That second point is the crucial one. A man taking DHEA hoping for more testosterone may convert a meaningful share of it to oestrogen instead, and there is no way to know without testing.

⚠ Banned in tested sport

DHEA is prohibited by WADA at all times, in and out of competition. It is also banned by the NCAA, the major professional leagues, and most military testing programmes.

If you are tested in any capacity, do not take this. That is not a cautious over-reading — DHEA is an anabolic agent under the WADA code, and it will produce a positive test.

⚠ 100mg is a substantial dose

Worth putting in context, because DHEA is sold at a wide range of strengths.

Much of the research on DHEA in older adults used 25 to 50mg daily. Studies in women frequently used lower amounts still, because women are considerably more sensitive to androgenic effects.

100mg per capsule is at the higher end of what is commonly sold, and it is not a starting dose for most people. If you are new to DHEA, splitting the capsule or sourcing a lower strength is the more sensible route.

Test rather than guess — this is the page where we mean it most

We say this about vitamin D too, but it matters more here.

DHEA is a hormone. Taking a hormone without knowing your baseline is guesswork with real consequences.

What to test: DHEA-S (the sulphated form, which is what labs measure), alongside total and free testosterone, and oestradiol. Retest after eight to twelve weeks of supplementation.

Why it matters: if your DHEA is already in the normal range for your age, supplementing is unlikely to help and may raise oestradiol. If it is genuinely low, you now have a baseline to measure against. Either way you learn something a bottle cannot tell you.

⚠ Side effects worth knowing

These follow directly from it being a hormone precursor.

In men: elevated oestrogen effects, including breast tissue sensitivity, are the most commonly reported concern. Acne and oily skin also occur. DHEA can suppress your own production over time, as with any exogenous hormone.

In women: androgenic effects — acne, facial hair growth, voice changes, menstrual irregularity. Women are considerably more sensitive to DHEA than men, and lower doses are standard.

In anyone: mood changes, sleep disturbance, and effects on cholesterol have all been reported.

Do not take DHEA if you have any hormone-sensitive condition — including breast, ovarian or prostate concerns. Speak to your doctor first if you take any medication, have liver disease, a heart condition, or a history of mood disorders.

Frequently asked questions

What is DHEA?
A hormone made by your adrenal glands that sits upstream of both testosterone and oestrogen. Your body converts it into those hormones.

Will it raise my testosterone?
Possibly, but you do not control the conversion. DHEA converts to both testosterone and oestrogen depending on your own enzyme activity and body composition — which is why bloodwork matters.

Can I take it if I'm drug tested?
No. DHEA is WADA-prohibited at all times and banned by the NCAA, professional leagues and most military testing programmes.

Is 100mg a lot?
It is at the higher end of what is sold. Much of the research in older adults used 25 to 50mg, and studies in women used less again.

Should I get bloodwork first?
Yes. Test DHEA-S, total and free testosterone, and oestradiol, then retest after eight to twelve weeks.

What are the side effects?
In men, oestrogen-related effects and acne. In women, androgenic effects including acne, facial hair and menstrual changes. Mood and sleep changes occur in both.

Should women take DHEA?
Not without medical guidance. Women are considerably more sensitive to it and research doses are much lower.

Is there a better first step?
For most people, yes — sleep, training, bodyweight, and correcting vitamin D, zinc and magnesium status.
