HelloPharmacist Scorecard of Pregnenolone 50 mg by MRM Nutrition

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 50 mg per capsule. Pregnenolone is a hormone precursor — your body naturally makes small amounts of it, and it can be converted into other hormones like estrogen, progesterone, and testosterone.

The capsule also contains rice flour and a cellulose capsule as inactive ingredients.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Pregnenolone's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: hormonal balance and healthy aging.
  • We looked for evidence on: Aging, Fatigue, Memory, Menopausal symptoms, Stress, cognitive function — and 2 related terms.
  • The closest evidence on file: Pregnenolone is rated "Insufficient Reliable Evidence To Rate" for Fatigue (Natural Medicines).
  • Also on file: Pregnenolone is rated "Insufficient Reliable Evidence To Rate" for Memory, Menopausal symptoms, Stress, Aging.

The data we hold shows insufficient reliable evidence to rate pregnenolone's effectiveness for alcohol use disorder, Alzheimer's disease, autism spectrum disorder, back pain, or bipolar disorder. That means research so far hasn't established whether it works for these uses — not that it doesn't work, but that we don't have strong evidence either way.

If you're considering it for a specific condition, talk with your doctor about what the current evidence actually supports.

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, but it is a hormone with limited human safety data, so it should be used only under guidance from a healthcare professional. The most commonly reported side effects in studies include acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor.

A few people have reported skin rashes with a burning sensation, possibly related to sun sensitivity, though the rash resolved on its own. During pregnancy, hormone supplements should be avoided due to unknown risks.

Breastfeeding is not recommended either, as there isn't enough safety information. If you're pregnant, planning pregnancy, or nursing, talk with your doctor before taking this product.

Side effects, ingredient by ingredient Pregnenolone

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, double-check with your doctor or pharmacist if you take estrogens (including birth control), progestins or progesterone supplements, testosterone therapy, or benzodiazepines (like diazepam or other anti-anxiety/sleep medications). Pregnenolone may enhance the effects of the first three groups and may reduce the effectiveness of benzodiazepines.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Pregnenolone may be worth considering if you're exploring it under a healthcare provider's supervision for a condition they've discussed with you — but the evidence for most uses isn't yet established. Because it interacts with birth control, hormone therapy, and certain sedative medications, you'll need to clear it with your doctor or pharmacist first, especially if you take any of those.

Start that conversation before you begin.

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 50 mg by MRM Nutrition: Common Questions

Does Pregnenolone 50 mg by MRM Nutrition interact with any medications?
Yes. Based on its ingredients, Pregnenolone 50 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 50 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 this if I'm on birth control?
Not without checking first. Pregnenolone can theoretically enhance the effects of estrogens and progestins in birth control, which could change how it works. 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. A few people have reported skin rashes with burning, possibly from sun sensitivity. If you notice any of these, mention it to your healthcare provider.
Is pregnenolone safe to take during pregnancy?
No. Hormone supplements should be avoided during pregnancy because the risks aren't known. If you're pregnant or planning to become pregnant, don't take this without your doctor's explicit guidance.
Will this help my memory or mood?
The evidence we have isn't strong enough to say whether pregnenolone works for Alzheimer's disease, bipolar disorder, or other memory and mood concerns. If you're considering it for one of these, ask your doctor what the current research actually supports.
Is this a natural hormone my body makes?
Yes — your body naturally produces small amounts of pregnenolone, and it serves as a building block for other hormones like estrogen, progesterone, and testosterone. This supplement provides an extra dose, which is why it needs to be used carefully and under professional guidance.
