HelloPharmacist Scorecard of Total Pregnenolone by Nutri-West

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

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 5 active ingredients.
  • “In a base of” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

This product has 5 ingredients, with pregnenolone as the active one. Pregnenolone is a hormone precursor — a natural compound your body makes and uses to build estrogen, progesterone, testosterone, and other steroid hormones.

The other ingredients are xylitol (a sweetener), fructose, maltodextrin (both fillers), and spearmint flavoring. There are no inactive other ingredients beyond those.

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.
  • We looked for evidence on: Memory, Aging, Cognitive function, Brain health.
  • 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 Aging.

The evidence for pregnenolone isn't established in our data. The facts we have show insufficient reliable evidence to rate it for alcohol use disorder, Alzheimer disease, autism spectrum disorder, back pain, and bipolar disorder — meaning we simply don't have enough quality research yet to say whether it works for those uses.

The evidence, ingredient by ingredient Pregnenolone Xylitol

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 use it only under guidance from a healthcare professional. The most common side effects reported are acne, agitation, diarrhea, drowsiness, excitement, hair loss, skin abscesses, and sweating.

Some people have reported skin rashes, possibly linked to light sensitivity, and changes in mood or appetite. Pregnancy and breastfeeding are red flags with this ingredient: the safety data advises against pregnenolone during pregnancy and while breastfeeding due to unknown risks.

Xylitol, also in the product, is generally well tolerated at food amounts but can cause digestive upset at high doses and is highly toxic to dogs.

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 2 matched ingredients 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.

Check with your pharmacist before taking this if you're on estrogens (including birth control pills), benzodiazepines like diazepam (for anxiety or sleep), progestin, testosterone, or progesterone. These are the medication types pregnenolone may interact with at a Moderate level.

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.

Total Pregnenolone by Nutri-West: Common Questions

Does Total Pregnenolone by Nutri-West interact with any medications?
Yes. Based on its ingredients, Total Pregnenolone 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?
Total Pregnenolone contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 is it supposed to do?
Pregnenolone is a hormone precursor — a compound your body naturally makes and uses as a building block for estrogen, progesterone, testosterone, and other steroid hormones. The evidence for its effectiveness isn't established in our data yet, so we can't say what it works for based on research.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advises against pregnenolone during pregnancy and while breastfeeding because the risks are unknown. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before considering any hormone supplement.
What side effects might I experience?
The most commonly reported side effects are acne, agitation, diarrhea, drowsiness, excitement, hair loss, skin abscesses, and sweating. Some people have reported skin rashes that may be light-sensitive. These are generally mild, but if you notice any of these, talk to your healthcare provider.
Why do I need to check my medications with a pharmacist before taking this?
Pregnenolone is a hormone precursor that can theoretically boost the effects of estrogens, progestins, testosterone, and progesterone, and it may weaken benzodiazepines. If you're on any of those types of medications, pregnenolone could change how they work in your body.
Is xylitol in this supplement safe?
Xylitol is generally well tolerated at the amounts typically found in food, though it can cause digestive upset — like gas, bloating, or diarrhea — at higher doses. One important note: xylitol is highly toxic to dogs, so keep this product away from pets.
