DHEA is usually praised for its anti-aging properties. It can protect the heart and improve brain function. However, there are some drawbacks to DHEA supplements as well. Read more below to learn all you need to know about DHEA and DHEA-sulfate.

DHEA is a very important marker to monitor, especially if you haven’t been leading the best lifestyle or you have chronic health issues. With Lab Test Analyzer you can track DHEA levels and make sure they are always in the optimal range. Why wait until issues get out of hand and interfere with your work and daily life? Lab Test Analyzer has got you covered – it tracks your health and gives you actionable advice on how to improve it.

Introduction to DHEA and DHEA-S

steroid pathway

DHEA is a steroid hormone that is produced in the adrenal gland, gonads, and brains. It is a precursor to other hormones, namely estrogen and testosterone. DHEA levels are highest after birth and continue to lower as you age (R).

DHEA-sulfate (DHEA-S) is a sulfite derivative of DHEA. The body also turns it into androgen hormones. Not a lot of studies have been done on DHEA-S and its long-term effects, so it is not recommended for supplementation (R).  

DHEA Snapshot

When I take DHEA, I get a boost of energy, to a point where I can even get too hyper. It has some similar effects as pregnenolone, except I don’t notice any negative effects on my sleep. I like it.


  • Good for cognitive function
  • Protects the heart by reducing hypertension
  • Reduces inflammation
  • Prevents osteoporosis
  • Increases REM sleep
  • Helps fertility


  • Can contribute to substance abuse
  • Might cause cancer
  • Risk factor for psychotic symptoms
  • Can cause anxiety and hyperactivity for some

Health Benefits of DHEA and DHEA-S

1) DHEA Boosts Hormone Levels

DHEA levels affect testosterone and estrogen levels. They are precursors to hormones, which means that the body converts DHEA into these hormones (R).

Women can take supplements during menopause to increase their level of estrogen (R).

DHEA can be used to help alleviate sexual dysfunctions that are the result of poor hormone levels (R).

2) DHEA Improves Brain Function

DHEA improves memory by stimulating neurons and inhibiting cortisol. DHEA increases as more cognitive tasks were performed and working memory increased (R).

DHEA also enhances the emotional regulation of memory and the connections between the amygdala and hippocampus (memory center) (R).

In the rat model of Alzheimer’s, DHEA supplement reduced symptoms and improved memory (R).

DHEA levels in the brain control visual processing. It is involved with the amygdala-dependent changes of the brain and visual awareness and attention (R).

DHEA has anti-cortisol activity and protects against depression (R).

A meta-analysis (of 22 studies) showed that it improved depressive symptoms in both old and young patients. However, only 3 studies were focused on young patients (R).

3) DHEA Protects the Heart

Low levels of DHEA are associated with heart disease in men (R).

DHEA also reduced high blood pressure and lowered cholesterol (R).

4) DHEA Helps Increase Pregnancy Rate

Ovarian reserve is the capacity for the ovaries to produce a healthy egg that is ready for fertilization. Women taking DHEA with poor ovarian reserve, who also did not respond well to IVF, had a higher rate of pregnancy and higher ovarian reserve than women who did not take DHEA supplements (R).

5) DHEA and DHEA-S Helps With Weight Problems

DHEA-S only had affected the weight of obese men, but not women. DHEA-S supplementation led to weight loss and reduced blood insulin level (R).

Dogs that took DHEA supplement lost more weight than ones that took a placebo. They also had lower cholesterol (R).

DHEA supplementation led to huge weight loss in rats and also increased their energy usage (R).

On the other hand, women treated with 100 mg of DHEA had better improvements from anorexia than those that took placebos. Their weight increased, as well as their moods (R).

6) DHEA Lowers Insulin Resistance

Elderly humans that underwent six months of DHEA replacement therapy had decreased insulin resistance and improved glucose tolerance (R).

In obese rats, DHEA administration combined with exercise helped lower insulin resistance and increased weight loss.  Blood glucose and insulin sensitivity improved (R).

7) DHEA Helps Protect Against Inflammation

DHEA stops inflammation and restored normal colon length. It balanced the immune responses from bowel disease that cause damage (R).

DHEA reduced inflammation due to HIV and prevented neuron degeneration (R).

In the feline model of HIV (called FIV), DHEA also prevented neuron loss (R).

DHEA can prevent symptoms of asthma. It reduces inflammation in the lungs and reduces hyperreactivity of the airways (R).

8) DHEA Improves Sleep

DHEA administration improved sleep in humans. REM sleep increased, which meant better memory storage as well (R).

9) DHEA Improves Bone Health

DHEA increases bone (osteoblast) formation and inhibits bone (osteoblast) cell death. It increases bone volume and bone mineral density. It can also help prevent post-menopausal osteoporosis (R).

In a study done on South Korean men, DHEA was found to have the same positive effect on bone mass and help prevent male osteoporosis (R).

10) DHEA Protects Muscles

DHEA helps protect against muscle dystrophy. It helps protect against cell oxidation and prevents cell death. It increased the effects of antioxidants and stops muscle atrophy (R).

11) DHEA Relieves Problems Resulting from Menopause

After menopause, some women experience vaginal pain during sexual intercourse or severe dryness of the vagina. Intravaginal administration of DHEA administered led to improved vaginal health and lessened pain (R).

12) DHEA May Protect Against Colon Cancer

The spread of cancer to other body organs is a leading cause of cancer-related deaths. DHEA may stop the spreading of cancer by inhibiting certain pathways (R).

13) DHEA Helps with Lupus

DHEA provides a short-term benefit in those with Systemic Lupus Erythematosus (SLE). It lessened symptoms as well as lowered HDL cholesterol in lupus patients (R).


DHEA helps relieve tuberculosis symptoms in patients.  It clears bacteria and prevents tissue damage (R).

Conventional doctors will look at high or low DHEA levels and not mention anything, but these can indicate that certain processes in the body aren’t optimal.

Negative Effects of DHEA

Note: I take DHEA myself, so I’m not concerned about these potential negative effects.

Some side effects of DHEA include acne and excessive hair growth (R).

DHEA-S is not recommended for women because of the lack of studies done on long-term effects (R).

Because DHEA can increase testosterone in the body, it is prohibited in some professional sports (R).

1) Excess Levels of DHEA and DHEA-S May Cause Cancer

Post-menopausal women with higher levels of DHEA and DHEA-S in the blood also had higher incidences of breast cancer (R).

An excessive amount of DHEA (more than 50mg daily) can lead to more cancer cells in the body (R – unreliable study).

An overdose of DHEA leads to high incidence of cancer of the prostate gland, breast, colon, lung, and stomach (R – unreliable study).

2) DHEA Is Related to Mental Disorders

Patients with schizophrenia had higher levels of cortisol and DHEA-S compared to healthy patients, but they also were more likely to respond to antipsychotic treatment (R).

A high level might be a risk factor for psychotic symptoms. It was found that a higher number of patients with high levels was found to have a family history of major depressive disorders or psychotic symptoms (R).

3) DHEA Increases Addiction

DHEA might contribute to substance abuse. By responding to emotional and behavioral circumstances, DHEA increases addiction (R).

4) DHEA Aggravates Stress

Increased production of DHEA during high-stress levels can cause more psychological problems (R).

Technical Information

  • Ed Mule

    My 80 year old father has PS palsy, which is a progressive degenerative neurological condition. Has anyone conducted studies to determine if DHEA supplements help with PS palsy or similar Parkinson-llke symptoms?

  • James

    I think I read a Ben Greenfield post of 1-dhea being better then garden variety like from Amazon.

    My AMH level is very low of 0.4 ..I’m 28 yrs trying for pregnancy…is there any medicine to increase ANY LEVEL…PLEASE HELP

  • Georgina Jancic

    Dear Angela: So glad I found this site and your post. I have had a terrible peri- menopause and menopause and the terrible symptoms have nkt stopped and I am 100% sure it is my next to nothing DHEA which numerous test have shown. I too am in Canada. How do I get Dr.’s to co-operate. Healthcare is free but not always the best. I have seen an Endocronologist who has done nothing for me! I would appreciate any feedback. How did you go about getting prescribed. THANK YOU IN ADVANCE Did your family Dr. Prescribe you and how many mg.

  • Maddy

    Carol, I believe you are right. How much DHEA were you prescribed and taking daily? Tablet?

  • Maddy

    You are correct Bails, prednisone, methylprednisone, hydrocortisone, dexemethisone, and any other cortisol related steroids will put DHEA in the basement. Like to zero with prolonged use, even a few days. They supress ACTH and that is what stimulates the adrenals to make both cortisol and DHEA. If you have been on a long time, you cannot go cold turkey. You have to wean off the steroids or you could have adrenal insufficiency and quite literally that is life threatening.

  • Ofek

    Can I take DHEA on an empty stomach?

    1. Helen

      Hi, we recommend following the instructions on the product as it may vary.


    It would be relevant to know what dosage you and your friends were taking. (You may have listed it in one of your posts but I didn’t see it.) Thank you.

  • carol close

    DHEA can raise the risk of ovarian cysts and cancer because it increases testosterone. “The Association of Plasma DHEA and DHEA Sulfate with Breast Cancer Risk in Predominantly Premenopausal Women.” “Changes in ovarian morphology and serum hormones in the rat after treatment with dehydroepiandrosterone.” “Comparative effects of DHEA vs. testosterone, dihydrotestosterone, and estradiol on proliferation and gene expression in human LNCaP prostate cancer cells.” “PCOS and Adrenal Glands- Hormones.”

    Clomiphene citrate, a drug given to induce ovulation, FSH (follicle stimulating hormone), the progestin only pill or IUD, the drug Tamoxifen, supplemental testosterone or DHEA, can all increase the risk of cysts forming.

  • Stella

    I have been supplementing with DHEA for over 10 years . I have had nothing but positive results I am hdppy to say. No negative side effects as of yet. I believe it contributes to my positive moids, no vaginal dryness, an increased libido and mental clarity I did extensive research before I started taking it & began my therapy with 10mg tablets in my 50’s, now in my 60’s I take 25 mg per day.

  • Apple

    Your so correct Peter 100mg is way to much.

  • Apple

    Dhea have remarkable rewards when taken at 10mg to 25mg a day for women. You had terrible side effects because you were taking 80mg more then doctors recommend for women. Dhea taken in more then 25mg a day for women will cause facial hair, deepen voice, oily skin, unnatural hair growth, and irregular periods. 100mg a day is far to much.

  • Angela

    HI, we can’t buy it over the counter here in Canada either but your doctor can test for it. My lab results came back showing it was low and he prescribed 10 mg for me. That’s the best way to find out if you need it. Not something you really want to just experiment with. But you do have to ask as they don’t normally test for it seems.

    1. Nattha Wannissorn, PhD

      You can import from the US for personal consumption. I have gotten some from Biomatrix. I didn’t do well with it though.

  • Bails

    Hi Joseph, I’ve been really loving your site since hearing you talk on BalancedBites podcast. I’ve recently been tested for DHEAS, and have a serum level of 0.1!! Reference levels are 1 – 10… I have a chronic vasculitis condition for which i take prednisone daily, I read that corticosteriods can suppress DHEA production. I wondered if you could recommend supplements/foods that can boost DHEA production – I live in New Zealand and we can’t buy DHEA over the counter. Many thanks for all the effort you put into the research on this site…

    1. Nattha Wannissorn, PhD

      Hi Bails,
      Thanks for the kind words. I’m not sure if taking DHEA would be good for your condition.
      Joe doesn’t respond to personal health questions on the site, so if you really need advice, can consider getting a consult ( or join VIP ( to get your questions answered.

    Here is a link that DHEA supplementation makes women develop Polycystic Ovary Syndrome 
    Changes in ovarian morphology and serum hormones in the rat after treatment with dehydroepiandrosterone.  
    (Serum androgens, estrogens, and prolactin concentrations are significantly increased in DHEA-treated animals as compared with controls. There was no significant difference in follicle stimulating hormone between those with cysts and rats without cysts after DHEA treatment. After 20 days of DHEA treatment, rats with Corpus Luteals have very high levels of luteinizing hormone. Luteinizing hormone and prolactin levels are significantly higher in rats with cysts than in rats without cysts after 10 days of DHEA treatment. As has been shown in this inquiry, androgens and estradiol levels in rats with cysts after DHEA treatment are higher than those in rats without cysts after DHEA treatment. Therefore, this study suggests that the ovarian cystic condition developed after DHEA treatment in rats, is associated with higher levels of circulating androgens, estradiol, and prolactin.)

    1. Nattha Wannissorn, PhD

      It’s a rat study, but I agree that DHEA acts like an androgen. I myself had trouble with it because it converted to too much testosterone. Some women may do okay with it, though.

      1. carol close

        No, I doubt any woman would be OK on DHEA. We are warning women not to take DHEA! My girlfriends and I believed the hype about DHEA’s anti aging benefits; however, we have personal experience that was extremely detrimental when taking DHEA. One girlfriend had her doctor prescribe DHEA to help her get pregnant which research now shows supplementing with DHEA does the opposite and reduces pregnancy. See the Pubmed research below. This girlfriend never recovered from DHEA’s effects. She lost her boobs, has a deep voice, and looks manly now. I was lucky to just get a couple of whiskers which went away after stopping DHEA as I did not supplement for long. This has happened to many girlfriends taking DHEA- facial hair! Yikes! I am warning every female user of DHEA about what happens to us! You have not read my prior Pubmed research I listed here on this thread. Some information is wrong on this Blog about DHEA and needs to be corrected. DHEA research shows it does NOT improve pregnancy rates! Research suggested it would help in pregnancy, then later research refuted this. DHEA does not decrease weight, but increases weight! BMI decreases in men, but increases in women. and DHEA increases cholesterol levels in women because in women DHEA is potently androgenic! Excess DHEA supplementation causes androgen excess and may cause increased acne, decreased breast size, a deep voice, increased genital size, irregular periods, oily skin, and unnatural hair growth. In women, but not in men, serum androstenedione, testosterone and DHT were increased to levels above gender-specific young adult ranges. SHBG declined and GHBP declined in women even though they were on estrogen replacement therapy at the same time. I wonder what DHEA would be like for women not ovulating or on hormone replacement- It has got to be very scarey to see what they turn into!!

  • carol close “Efficacy of dehydroepiandrosterone to improve ovarian response in women with diminished ovarian reserve: a meta-analysis.” There was no significant difference in the clinical pregnancy rate and miscarriage rates between women pre-treated with DHEA compared to those without DHEA pre-treatment. The number of oocytes retrieved was significantly lower in the DHEA group. In conclusion, based on the limited available evidence from a total of approximately 200 IVF cycles, there are insufficient data to support a beneficial role of DHEA as an adjuvant to controlled ovarian stimulation in IVF cycle. (My girlfriend who was trying to get pregnant was prescribed DHEA by her doctor. Results: she did not get pregnant. Her voice deepened. She became flat chested and muscular. She has not looked the same since the DHEA supplements, even though she stopped taking the supplements! My sister-in-law and I tried DHEA, but stopped because we both sprouted a whisker on our chin! My cholesterol HDL went down 20 and my LDL cholesterol went up 30 and I gained 10 pounds without changing my diet! We are warning women not to take DHEA!)

  • carol close “The effect of six months treatment with a 100 mg daily dose of dehydroepiandrosterone (DHEA) on circulating sex steroids, body composition and muscle strength in age-advanced (50-65 year old) men and women.” A daily oral 100 mg dose of DHEA for 6 months resulted in elevation of circulating DHEA and DS concentrations and the DS/cortisol ratio. Biotransformation to potent androgens near and slightly above the range of their younger counterparts occurred in women with no detectable change in men. Given this hormonal milieu, an increase in serum IGF-I levels was observed in both genders but dimorphic responses were evident in fat body mass and muscle strength in favour of men. These differences in response to DHEA administration may reflect a gender specific response to DHEA and/or the presence of confounding factor(s) in women such as oestrogen replacement therapy.

    1. Peter Rutkiewicz

      DHEA at the rate of 100 mg a day is a lot. Bodybuilders will use it but they are lifting weights which stimulates endocrine response. DHEA supplementation reduces the amount of work that the endocrine (adrenals, mostly) have to provide. I’m a male who lifts occasionally, runs, bikes and practices Yoga. I find 100 mg too much, causing a weight gain with a fat gain while 50 mg gets the lean muscle mass without the fat gain. For women I would recommend 1/2 that amount or 25 mg/day which is in line with Life Extension Foundation recommendations for women 60 and over. If you are a younger woman having trouble with conception. I highly recommend an endocrine workup that touches on all relevant hormones. You will learn how to adjust your diet to optimally support your fertility. Some men have to do this too. From personal experience. adjustments to diet. lifestyle with some supplementation can make a huge difference in your libido and fertility. IMO no woman of child bearing age should take DHEA without an endocrinologist’s advice. Once past menopause and 60 yrs, 25 mg of DHEA can give your energy level a little boost because the endocrine system begins to shut down its output as we age. For many young working women, life stressors and cortisol imterfere with fertility. Yoga is a wonderful life enhancing activity to calm your mind and improve your health.
      Lots of pregnant women do Yoga and I’m quite sure they did Yoga before they got pregnant.

      1. carol close

        Life Extension Foundations recommendations for DHEA supplementation for women are not based on resources, research, and references with sound science evidence based information. Instead of DHEA, women should supplement with pregnenolone, which is the mother of all hormones. Women should not supplement with DHEA which is androgenic in women and causes masculine characteristics -especially if menopausal women are not on Hormone Replacement Therapy (see resources, research and references with sound science evidence noted here in this reply section.) Women who are in menopause should be on hormone replacement therapy with real estradiol in a transdermal patch and micronized progesterone inserted vaginally and both cycled in a monthly fashion as sex hormones are neurosteroids necessary for brain health, activate stem cells for cell regeneration, activate serotonin and dopamine neurons, activate the p53 tumor suppressor gene and inhibit mTOR which synthetic estrogen, estrone, conjugated equine estrogen and synthetic progesterone do not.

    DHEAS, the sulfated version of DHEA is the most abundant steroid in the human circulation. DHEA is a precursor to sex hormones. Women have lower levels of DHEA than men. DHEA levels decrease with age, so women at age 70 have levels of only 20% of what they were at age 20. Benefits of DHEA are stronger bones, stopping vaginal atrophy (applying DHEA in the vagina), and stopping muscle loss with age, but beware- sustained DHEA supplements (even when combined with natural estrogen hormone supplement replacement in menopausal women), raises male hormone levels in women to abnormally high levels- (DHEA supplements in women raise androstenedione, testosterone and dihydrotestosterone levels to abnormally high levels). So, DHEA supplement consumption leads to acne, deepened voices, decreased breast size, increased genital size, oily skin, unnatural hair growth, facial hair and negatively interacts with estrogen levels, increases bad cholesterol and decreases good cholesterol, causes tumors, heart rhythm problems, hair loss and insomnia which are signs of androgen excess. Many molecular causes for androgen excess exist, with one possibility- a failure in the sulfation pathway that converts DHEA to DHEAS, the most abundant steroid in the human circulation. Women with polycystic ovary syndrome have excess androgen levels which vitamin D has a positive effect. “The regulation of steroid action by sulfation.” In women, excess DHEA supplementation causes androgen excess and may cause decreased breast size, a deep voice, increased genital size, irregular periods, oily skin, and unnatural hair growth. “The effect of six months treatment with a 100 mg daily dose of dehydroepiandrosterone (DHEA) on circulating sex steroids, body composition and muscle strength in age-advanced men and women.” In women, but not in men, serum androstenedione, testosterone and DHT were increased to levels above gender-specific young adult ranges. In men, BMI decreased, but BMI increased in women. In women SHBG declined and GHBP declined in women even though they were on estrogen replacement therapy. “The role of vitamin D in polycystic ovary syndrome. “Vitamin D plays a physiologic role in reproduction including ovarian follicular development and luteinization via altering anti-müllerian hormone (AMH) signalling, follicle-stimulating hormone sensitivity and progesterone production in human granulosa cells1. It also affects glucose homeostasis through manifold roles. “The effects of Vitamin D-K-Calcium-Co supplementation on Endocrine, Inflammation, and oxidative stress biomarkers in Vitamin D deficient women with polycystic ovary syndrome: A randomized, double blind, placebo controlled trial.” They found no effect on FSH, prolactin, progesterone, inflammatory markers and glutathione. however, there were improvements in DHEA, testosterone, total antioxidant capacity and malondialdedehyde levels.

    What about 7-keto-DHEA? It supposedly doesn’t get converted into testosterone. Does anyone have therapeutic experience with 7-keto-DHA?

  • GM

    I think you need to clean up the negatives section here. The references look weak. They make DHEA look bad (DHEA is a natural bio-ideological hormone, at physiological doses there’s no reason it should cause cancer etc).

    1. Joseph M. Cohen

      I agree, I don’t necessarily agree with the negatives.

      I take DHEA myself, so I’m not concerned.

      1. Eddie Strike (@EddieStrike)

        You take it daily with pregnenolone too?

        1. Joseph M. Cohen

          Sometimes, but I take a lower dose of preg if I do

  • Paul

    One of the articles you reference, – suggests that a person take DHEA just once a month to once every four months. Do you agree? If not, how often should it be taken?

    1. Joseph M. Cohen


      1. kevin

        Hi, I dont get the answer here Joseph, what do you mean by no? thx

  • Katja Bloigu

    One important thing is missing here. Dhea helps people with autoimmune disease to tolerate the heat. Those who have lack of hormones in adrenal glances. That is why I take it. 25 mg daily, but not on cold season. No side effects.
