HelloPharmacist Scorecard of Pregnenolone 50 mg Super Strength by Swanson

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, a hormone precursor your body naturally produces. Pregnenolone can be converted into several steroid hormones, including estrogen, progesterone, testosterone, and DHEA, which is why it's sometimes taken as a supplement for hormone-related concerns.

The inactive ingredients are rice flour, gelatin, and calcium palmitate—common capsule fillers and binders.

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: supports hormone health and memory function.
  • We looked for evidence on: Memory, Stress, Fatigue, Aging, cognitive decline, hormonal balance.
  • 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, Stress, Aging.

The evidence for pregnenolone's effectiveness is insufficient to rate for the conditions studied. Our data covers alcohol use disorder, Alzheimer disease, autism spectrum disorder, back pain, and bipolar disorder, but reliable evidence to support its use for any of these hasn't been established in the data we hold.

If you're considering this supplement for a specific reason, talk with your doctor or pharmacist about whether the current evidence supports that use.

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. The most commonly reported side effects include acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor.

A few people have reported skin abscesses, and one case of a rash with burning on the hands was noted—possibly tied to sun sensitivity—though it cleared on its own. Because pregnenolone is a hormone with limited human safety data, it should only be used under guidance from a healthcare professional.

Pregnancy and breastfeeding safety data aren't established. Hormone supplements should be avoided during pregnancy due to unknown risks, and there isn't enough safety information to recommend it while breastfeeding.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist 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 pregnenolone, double-check with your doctor or pharmacist if you take estrogen medications (including birth control), progestin, progesterone, testosterone, or benzodiazepines. Pregnenolone may enhance estrogen, progestin, progesterone, and testosterone effects, and it may reduce how well benzodiazepines work.

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 is a hormone precursor that interacts with several hormone medications and benzodiazepines. It's generally well tolerated but can cause side effects like acne and agitation, and it's a hormone supplement with limited safety data—so it's not something to take casually.

If you take any hormone medications, anti-anxiety drugs, or have specific health concerns you're hoping to address, discuss this supplement with your own doctor or pharmacist before starting.

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 Super Strength by Swanson: Common Questions

Does Pregnenolone 50 mg Super Strength by Swanson interact with any medications?
Yes. Based on its ingredients, Pregnenolone 50 mg Super Strength 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 Super Strength 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.
What is pregnenolone and what does it do in the body?
Pregnenolone is a hormone your body makes naturally. It acts as a building block for several other hormones, including estrogen, progesterone, testosterone, and DHEA. When you take it as a supplement, it can be converted into these other hormones, which is why people take it for hormone-related concerns.
Can I take this if I'm pregnant or breastfeeding?
No. Hormone supplements should be avoided during pregnancy because the risks aren't known, and there isn't enough safety information to use it while breastfeeding. Talk with your doctor or pharmacist about whether this is right for you if you're pregnant, planning to become pregnant, or nursing.
What side effects might I experience?
The most common are acne, agitation, diarrhea, drowsiness, excitement, hair loss, sweating, and tremor. Some people have reported skin abscesses or a rash. Pregnenolone is generally well tolerated, but because it's a hormone with limited safety data, you should use it only under guidance from a healthcare professional.
Will this help with Alzheimer disease, back pain, or bipolar disorder?
There isn't reliable evidence in the data we hold to support pregnenolone for those conditions. If you're taking it for a specific health concern, talk with your doctor or pharmacist about whether the current research supports that use.
Does this product have any fillers or additives?
Yes. Beyond the active pregnenolone, the capsule contains rice flour, gelatin, and calcium palmitate, which are common inactive ingredients used as binders and fillers.
