HelloPharmacist Scorecard of Pregnenolone 10 mg by Vital Nutrients

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 3, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: pregnenolone 10 mg per capsule. Pregnenolone is a hormone precursor — your body naturally makes it, and it's the raw material from which your brain and body manufacture estrogens, progesterone, testosterone, and other steroid hormones.

The inactive ingredients are rice powder, cellulose, and silica.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Pregnenolone product and its label doesn't state a use — see Pregnenolone's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence on pregnenolone isn't established in the data we hold. Our monograph lists several conditions — alcohol use disorder, Alzheimer's disease, autism spectrum disorder, back pain, and bipolar disorder — but for each one, the rating is insufficient reliable evidence to rate.

That means the research either hasn't been done, is too small or weak, or is simply too mixed to draw a conclusion.

The evidence, ingredient by ingredient Pregnenolone

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pregnenolone is generally well tolerated when taken by mouth. That said, it's a hormone with limited human safety data, so you should use it only under guidance from your own healthcare professional.

Common side effects reported in trials include acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor. Less commonly, skin rashes with burning sensations (possibly light-related) and changes in mood or appetite have been reported.

Don't take pregnenolone during pregnancy — hormone supplements carry unknown risks, and the safety data advises against it. Avoid it while breastfeeding as well; there isn't enough safety information to know either way.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Pregnenolone.
  • The most serious interaction on file is rated Moderate.
  • For scale: 82 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, check with your doctor or pharmacist if you're on estrogens, progestins, testosterone, or progesterone (including birth control and hormone replacement therapy) — pregnenolone may strengthen their effects. Also flag any benzodiazepines you take for anxiety or sleep, as pregnenolone may reduce how well they work.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Pregnenolone is a natural hormone precursor that's generally well tolerated, but it comes with limited human safety data and moderate interactions with birth control, hormone replacement therapy, testosterone therapy, and anxiety medications. If you take any of those, or any other prescription medication, check your exact drugs with the search tool on this page before you start.

Talk it over with your own doctor or pharmacist to make sure it's a fit for you.

Pregnenolone5 drug types · 82 drugs

Benzodiazepines

Concomitant use of pregnenolone may reduce the effects of benzodiazepines.
Very preliminary clinical research shows that chronic use of pregnenolone reduces sedative effects of diazepam when compared with chronic use of placebo. This effect may be related to the activity of pregnenolone at GABAA receptors.

Likelihood Probable Evidence B
Estrogens

Theoretically, taking pregnenolone might enhance the effects of estrogens.
Pregnenolone is a precursor for several steroid hormones, including estrogens.

Likelihood Possible Evidence D
Progesterone

Theoretically, taking pregnenolone might enhance the effects of progesterone.
In humans, some research shows that oral administration of pregnenolone can increase levels of progesterone. However, other research shows no effect on progesterone levels. It is possible the impact of pregnenolone on progesterone levels may be dose dependent.

Likelihood Possible Evidence D
Progestin

Theoretically, taking pregnenolone might enhance the effects of progestin.
Pregnenolone is a precursor for several steroid hormones, including progestin.

Likelihood Possible Evidence D
Testosterone

Theoretically, taking pregnenolone might enhance the effects of testosterone.
Pregnenolone is a precursor for several steroid hormones, including testosterone. However, preliminary clinical research shows that taking pregnenolone 30-500 mg orally daily for up to 8 weeks does not affect testosterone levels.

Pregnenolone 10 mg by Vital Nutrients: Common Questions

Does Pregnenolone 10 mg by Vital Nutrients interact with any medications?
Yes. Based on its ingredients, Pregnenolone 10 mg has a known interaction with 82 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pregnenolone 10 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Can I take pregnenolone if I'm on birth control?
Not without checking first. Pregnenolone can theoretically boost the effects of estrogens and progestins in birth control, which could change how it works or raise your risk of side effects. Talk with your doctor or pharmacist before combining them.
What side effects should I watch for?
The most common ones are acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor. Skin rashes and changes in appetite or mood have also been reported. If any of these bother you or don't go away, let your healthcare provider know.
Is pregnenolone safe during pregnancy?
No. Hormone supplements should be avoided during pregnancy because the risks aren't known. If you're pregnant or planning to be, don't take this product without talking to your doctor.
Can I breastfeed while taking pregnenolone?
There isn't enough safety information to know either way. Talk with your doctor or pharmacist about whether it's okay for you and your baby before you use it.
Does this actually work for the conditions it claims to help?
The evidence isn't established yet. Our data shows insufficient reliable evidence for conditions like Alzheimer's disease, back pain, and bipolar disorder — meaning the research hasn't been done or is too mixed to say whether it helps.
What's pregnenolone and why do I need it?
Pregnenolone is a hormone your body naturally makes. It's a building block your brain and body use to create estrogens, progesterone, testosterone, and other steroid hormones. Whether you need a supplement is an individual question for your doctor.
