HelloPharmacist Scorecard of Pregnenolone 50 by Allergy Research Group

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.

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.

Pregnenolone 50 contains a single active ingredient: pregnenolone, a naturally occurring hormone precursor in your body. The tablet also includes several inactive ingredients—microcrystalline cellulose, vegetable oil, vegetable wax, magnesium stearate, vitamin E, and other excipients that help hold the tablet together and aid absorption.

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 we hold does not establish whether pregnenolone works for any of the conditions listed in the product facts. For alcohol use disorder, Alzheimer's disease, autism spectrum disorder, back pain, and bipolar disorder, the data shows insufficient reliable evidence to rate its effectiveness.

If you're considering this supplement for a specific health concern, talk it over with your doctor or pharmacist about what the current research 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 and should only be used under guidance from a healthcare professional. The most common side effects reported include acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor.

A few cases of skin rash with burning sensations on the hands have also been reported, possibly related to sun sensitivity, though these cleared on their own. The safety data advises against use during pregnancy due to unknown risks, and not enough information exists to recommend it while breastfeeding—talk with your doctor or pharmacist before taking pregnenolone if you are pregnant, trying to become pregnant, or nursing.

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 Pregnenolone 50, double-check with your doctor or pharmacist if you take benzodiazepines (like diazepam, used for anxiety or seizures)—pregnenolone may reduce their sedative effects. Also confirm it's okay if you use any estrogen-containing medications, progestin products (like birth control or hormone therapy), testosterone therapy, or progesterone supplements, since pregnenolone may theoretically enhance their effects.

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 50 is a hormone supplement that works as a building block for several sex hormones and may interact with hormonal medications and benzodiazepines. If you take birth control, hormone therapy, testosterone, progesterone, or any sedative medication, check with your own doctor or pharmacist before starting it.

Because it's a hormone with limited safety data, use it only under professional guidance.

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 by Allergy Research Group: Common Questions

Does Pregnenolone 50 by Allergy Research Group interact with any medications?
Yes. Based on its ingredients, Pregnenolone 50 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 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.
Is pregnenolone safe to take during pregnancy?
No—the safety data advises against use during pregnancy due to unknown risks to your baby. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before taking this supplement.
Can I take this while breastfeeding?
There isn't enough safety information to know either way. Because it's a hormone, you should check with your doctor or pharmacist before taking pregnenolone while breastfeeding.
What side effects might I notice?
The most common ones reported are acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor. A few people have reported skin rashes that felt like sun sensitivity, though these cleared on their own. If you notice any new skin changes or mood shifts, let your doctor know.
Does pregnenolone actually work for the conditions listed?
The evidence we hold doesn't establish whether it works for alcohol use disorder, Alzheimer's disease, autism, back pain, or bipolar disorder. The research isn't strong enough yet to rate it as effective for any of these.
Why is this a hormone supplement and not a vitamin?
Pregnenolone is a steroid hormone your body naturally makes—not a vitamin. Because it's a hormone, it can be converted into other hormones like estrogen, progesterone, and testosterone, which is why it may interact with hormonal medications and why it requires professional guidance to use.
