HelloPharmacist Scorecard of Pantethine Complex 300 mg by The Vitamin Shoppe

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains two active ingredients: pantothenic acid (also called vitamin B5) and pantethine. Pantothenic acid is a B vitamin your body uses to break down food and make energy.

Pantethine is a related compound that may help support healthy cholesterol and fat metabolism. The tablet also contains several inactive ingredients—dicalcium phosphate, microcrystalline cellulose, stearic acid, croscarmellose sodium, magnesium stearate, purified water, hydroxypropyl methylcellulose, polyethylene glycol, and titanium dioxide—which help hold the tablet together and aid in absorption.

Does it work?

Strong 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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Pantothenic acid deficiency — rated "Effective" (Pantothenic Acid) (Natural Medicines).
  • On file: Hyperlipoproteinemia — rated "Possibly Effective" (Pantethine) (Natural Medicines).

Pantothenic acid is effective for treating pantothenic acid deficiency. For other uses like radiation dermatitis, hay fever, and hair loss, the evidence is insufficient or suggests it likely doesn't work.

Pantethine is possibly effective for high cholesterol (hyperlipoproteinemia). For athletic performance and other forms of high cholesterol, there isn't enough reliable evidence to say whether it works.

The evidence, ingredient by ingredient Pantothenic Acid Pantethine

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.

Pantothenic acid is generally well tolerated at typical supplement doses. The main oral side effect reported is diarrhea.

The safety notes advise checking with your doctor before taking high doses, though amounts in food and prenatal vitamins are fine. Pantethine also appears well tolerated in studies, but long-term safety data are limited.

The most common side effects are mild gastrointestinal complaints—nausea, vomiting, diarrhea, bloating, and flatulence—and mild itching is uncommon. For pregnancy, there isn't enough data to know whether pantethine is safe, so talk it over with your doctor or pharmacist.

For breastfeeding, safety hasn't been well studied, and caution is advised.

Side effects, ingredient by ingredient Pantothenic Acid Pantethine

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 2 matched ingredients can interact with medications — Pantethine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 122 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.

If you take any blood thinners (anticoagulants like warfarin) or antiplatelet drugs (like aspirin or clopidogrel), double-check with your doctor or pharmacist before adding this product—pantethine may increase your bleeding risk. No other interactions are documented for pantothenic acid.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

If you're looking to support healthy cholesterol levels, pantethine may be worth considering, though the evidence is modest. If you take blood thinners or antiplatelet medications, check with your doctor or pharmacist before starting this product—pantethine could increase your bleeding risk.

Gastrointestinal side effects like nausea or diarrhea are possible but usually mild.

Pantethine Complex 300 mg by The Vitamin Shoppe: Common Questions

Does Pantethine Complex 300 mg by The Vitamin Shoppe interact with any medications?
Yes. Based on its ingredients, Pantethine Complex 300 mg has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pantethine Complex 300 mg contains 2 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.
Is this safe to take while I'm pregnant or breastfeeding?
Pantothenic acid is likely safe in pregnancy and while breastfeeding at typical dietary levels. Pantethine is different—there isn't enough safety data to know either way. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy or nursing.
What side effects might I experience?
Both ingredients are generally well tolerated. The most likely side effect is mild gastrointestinal discomfort—nausea, diarrhea, bloating, or flatulence. Diarrhea has also been reported with pantothenic acid alone. Mild itching is uncommon but possible.
Does pantethine actually help lower cholesterol?
Pantethine is possibly effective for high cholesterol. The evidence suggests it may help, but it's not a strong or certain effect. Talk with your doctor about whether it makes sense for your situation.
What's the difference between pantothenic acid and pantethine?
Pantothenic acid is a B vitamin your body needs for energy and metabolism. Pantethine is a related compound that may support healthy cholesterol levels. This product contains both.
Is there enough long-term safety data on pantethine?
No—studies show it's well tolerated in the short term, but we don't have enough long-term safety data. If you plan to use this regularly, discuss it with your doctor or pharmacist.
Can I take this if I'm on a blood thinner?
Pantethine may increase bleeding risk with blood thinners and antiplatelet drugs. Do not take this product without checking with your doctor or pharmacist first if you're on any of these medications.
