Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: vitamin C and dehydroepiandrosterone (DHEA). Vitamin C is a water-soluble vitamin that plays a role in immune function and collagen formation.

DHEA is a hormone precursor—your body can convert it to estrogen or testosterone. The inactive ingredients are rice bran and gelatin (the capsule material).

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: slows aging, enhances memory, supports energy.
  • We looked for evidence on: Aging, Cognitive function, Athletic performance, Age-related cognitive decline, Fatigue.
  • The strongest evidence on file: Dhea is rated "Possibly Effective" for Aging skin (Natural Medicines).
  • Also on file: Dhea is rated "Possibly Ineffective" for Aging.
  • Also on file: Dhea is rated "Likely Ineffective" for Cognitive function.

For vitamin C, the evidence supports it as effective for vitamin C deficiency. It's rated possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and reducing respiratory infections triggered by exercise.

For DHEA, the evidence shows it's likely effective for vaginal atrophy. It's rated possibly effective for infertility, aging skin, and depression.

The evidence, ingredient by ingredient Vitamin C Dhea

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin C is generally well tolerated at normal doses, but very high doses can cause stomach cramps, diarrhea, heartburn, nausea, and kidney stones (especially in people prone to them). Adverse effects are more likely above 2 grams daily.

DHEA should only be used with medical guidance—it's a hormone and carries hormonal side effects. Common effects include acne, headache, insomnia, mood changes, and nausea.

In women, it can cause voice deepening, irregular periods, increased facial hair, and reduced breast size. In men, aggression and breast tenderness have been reported.

DHEA is not safe in pregnancy and there isn't enough safety data for breastfeeding—avoid both. Vitamin C at normal dietary amounts and from prenatal vitamins is fine, but high-dose supplements in pregnancy should only be taken if your doctor advises it.

Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Dhea, Vitamin C.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; cancer treatments.
  • For scale: 861 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (DHEA increases bleeding risk and vitamin C can reduce warfarin effectiveness), anti-cancer hormone therapies like aromatase inhibitors or tamoxifen, antidepressants, thyroid medication, oral contraceptives or hormone replacement therapy, chemotherapy drugs, sedatives like triazolam, or psychiatric medications. DHEA may also reduce the tuberculosis vaccine's effectiveness.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product combines a common vitamin with a hormone, so it's not one-size-fits-all. If you take any prescription medication—especially blood thinners, hormone therapies, antidepressants, or thyroid medication—check with your doctor or pharmacist before starting.

DHEA in particular requires medical oversight because it affects hormone levels and interacts with cancer therapies and psychiatric drugs.

Dehydroepiandrosterone10 drug types · 776 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, DHEA might increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Human and laboratory research show that DHEA and DHEA-S can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidepressant Drugs

Theoretically, DHEA might increase the risk of psychiatric adverse events when used with antidepressants.
In a human case report, the use of a selective serotonin reuptake inhibitor (SSRI) with DHEA caused a manic episode. Concern for this interaction may be greater in younger individuals with higher baseline DHEA levels.

Likelihood Possible Evidence D
Aromatase Inhibitors

Theoretically, DHEA might interfere with the clinical effects of aromatase inhibitors.
DHEA is a potent estrogen agonist, which may antagonize the anti-estrogen activity of aromatase inhibitors.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, DHEA might increase the levels of drugs metabolized by CYP3A4.
Some preliminary evidence shows that DHEA may inhibit CYP3A4; however, the clinical significance of this potential interaction is not known.

Likelihood Possible Evidence D
Fulvestrant (Faslodex)

Theoretically, DHEA might interfere with the anti-estrogen effects of fulvestrant.
DHEA is a potent estrogen agonist. Some research shows that it can overcome the estrogen receptor antagonist action of fulvestrant in estrogen-receptor positive cancer cells.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, DHEA might interfere with the anti-estrogen effects of tamoxifen.
DHEA is a potent estrogen agonist. Some research shows that it can overcome the estrogen receptor antagonist activity of tamoxifen in estrogen-receptor positive cancer cells.

Likelihood Possible Evidence D
Triazolam (Halcion)

DHEA can increase blood levels of triazolam.
Administration of DHEA 200 mg daily for two weeks was shown to inhibit the cytochrome P450 3A4 (CYP3A4) metabolism of triazolam. This inhibition appears to be due to DHEA-S, rather than DHEA.

Likelihood Probable Evidence D
Tuberculosis Vaccine

DHEA might reduce the effectiveness of the tuberculosis vaccine.
Animal research shows that high doses of DHEA can reduce the efficacy of the Bacillus Calmette-Guérin (BCG) tuberculosis vaccine.

Likelihood Possible Evidence D
Estrogens

Theoretically, DHEA might increase the effects and adverse effects of estrogen therapy.
DHEA is a precursor to estrogen and androgen and is metabolized into those substances. In clinical research, DHEA supplements increase the levels of these hormones. Also, in clinical research, estrogen-progestin oral contraceptives and conjugated estrogens reduce blood levels of DHEA and DHEA-S. The clinical significance of these findings is unclear.

Likelihood Possible Evidence D
Testosterone

Theoretically, DHEA might increase the effects and side effects of testosterone therapy.
DHEA is a precursor to estrogen and androgen and is metabolized into those substances. In clinical research, DHEA supplements increase the levels of these hormones. The clinical significance of these findings is unclear.

Vitamin C13 drug types · 207 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Aluminum

Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.

Likelihood Probable Evidence B
Antitumor Antibiotics

Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Estrogens

Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.

Likelihood Probable Evidence B
Fluphenazine (Prolixin)

Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.

Likelihood Possible Evidence D
Indinavir (Crixivan)

Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.

Likelihood Probable Evidence B
Warfarin (Coumadin)

High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.

Likelihood Probable Evidence B
Aspirin

Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction is not clinically significant.

Likelihood Possible Evidence B
Choline Magnesium Trisalicylate (Trilisate)

Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Niacin

Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Salsalate (Disalcid)

Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

DHEA 25 mg by Bronson Laboratories: Common Questions

Does DHEA 25 mg by Bronson Laboratories interact with any medications?
Yes. Based on its ingredients, DHEA 25 mg has a known interaction with 860 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
DHEA 25 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is it safe to take DHEA while pregnant or breastfeeding?
No—DHEA is rated possibly unsafe in pregnancy and there isn't enough safety data for breastfeeding, so you should avoid it in both. Vitamin C at normal amounts from food and prenatal vitamins is fine, but high-dose supplements should only be taken if your doctor advises it. Talk with your doctor or pharmacist about your specific situation.
What are the most common side effects of DHEA?
Acne (especially in women), headache, insomnia, mood changes, and nausea are the most frequently reported. Women may also experience voice deepening, irregular periods, increased facial hair, and reduced breast size. Men may report aggression and breast tenderness. Most side effects are mild, though acne can sometimes be managed by lowering the dose.
Can high-dose vitamin C cause problems?
Yes—above 2 grams daily, vitamin C can trigger stomach cramps, diarrhea, heartburn, nausea, and kidney stones (if you're prone to them). This product contains a modest amount, but if you're taking other vitamin C supplements or megadoses, check your total daily intake with your pharmacist.
What does DHEA do in the body?
DHEA is a hormone precursor—your body can convert it into estrogen or testosterone. It's rated likely effective for vaginal atrophy and possibly effective for infertility, aging skin, and depression, though the evidence varies.
Will this product affect my birth control or hormone replacement therapy?
Potentially. Vitamin C may increase blood levels of estrogens in oral contraceptives and hormone therapy by up to 55% under some circumstances. DHEA is also an estrogen agonist. Talk with your doctor or pharmacist before adding this to your routine—you may need dose adjustments or closer monitoring.
