HelloPharmacist Scorecard of Pregnenolone 50 mg by Emerald Labs

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 Oct 1, 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 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: pregnenolone and tocotrienol complex. Pregnenolone is a hormone precursor — your body can convert it into other steroid hormones like estrogen, progesterone, and testosterone.

Tocotrienols are a form of vitamin E with antioxidant properties. The capsule itself is made from vegetable material.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: memory and cognitive support with stress management.
  • We looked for evidence on: Age-related cognitive decline, Memory, Stress, cognitive aging, hormonal support, adrenal function.
  • The closest evidence on file: Pregnenolone is rated "Insufficient Reliable Evidence To Rate" for Memory (Natural Medicines).
  • Also on file: Pregnenolone is rated "Insufficient Reliable Evidence To Rate" for Stress, Aging.
  • Also on file: Tocotrienols is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline, Aging.

The data we hold shows insufficient evidence to rate pregnenolone for the conditions listed — including Alzheimer disease, autism spectrum disorder, back pain, bipolar disorder, and alcohol use disorder. For the tocotrienol complex, the evidence suggests it may be possibly effective for diabetes management, though the data on cholesterol lowering rates it as possibly ineffective.

The evidence on other uses — hair loss and breast cancer — isn't established in our data.

The evidence, ingredient by ingredient Pregnenolone Tocotrienols

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.

Pregnenolone is generally well tolerated when taken by mouth, but it's a hormone with limited human safety data, so it 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.

Some people have experienced skin rashes, depressive symptoms, or changes in appetite. Tocotrienols appear well tolerated in studies, though long-term safety at supplement doses isn't well established.

The safety data advises against pregnenolone during pregnancy due to unknown risks, and it should be avoided while breastfeeding. For tocotrienols, there isn't enough safety information during pregnancy or breastfeeding — talk with your doctor or pharmacist about whether it's right for you if you're 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?
  • 2 of the 2 matched ingredients can interact with medications — Pregnenolone, Tocotrienols.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 204 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 use estrogens, progestins, progesterone, testosterone, benzodiazepines (sedatives like diazepam), or blood thinners and antiplatelet drugs — all carry documented interactions with ingredients in this product. Pregnenolone may enhance hormone effects or reduce how well sedatives work; blood thinners may carry a higher bleeding risk when combined with the tocotrienol complex.

The bottom line

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

Pregnenolone is a hormone precursor best approached with caution and professional oversight, especially if you're on any hormone medications or sedatives. The tocotrienol complex is a secondary ingredient here and appears well tolerated.

This isn't a casual supplement — discuss it with your doctor or pharmacist before starting, particularly if you take birth control, hormone replacement therapy, blood thinners, or benzodiazepines.

Label statements
These statements are the manufacturer’s wording, reproduced from the product label — the label is saying it, not HelloPharmacist. We don’t verify or endorse them.
Formula

Pregnenolone is naturally produced in the body by the adrenal glands. Pregnenolone is often called the "The Master Hormone" because it can be converted into many other steroidal hormones. Because production levels slow with age, supplementation may help to support more youthful Pregnenolone levels.

Tocotriene Complex1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Concomitant use of tocotrienols with anticoagulant or antiplatelet agents might increase the risk of bleeding. However, this has not been reported in humans.
Taking tocotrienols orally inhibits experimentally-induced platelet aggregation in humans. Theoretically tocotrienols might increase the risk of bleeding if taken with antiplatelet or anticoagulant drugs. However, tocotrienols 400-800 mg daily have been used with aspirin and/or clopidogrel for 1 year with no clear cumulative antiplatelet effects and no reports of bleeding.

Likelihood Unlikely Evidence B
Tocotriene Complex full monograph & interactions

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.
