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.

This supplement contains one active ingredient: pantothenic acid (also called vitamin B5) at 450 mg per capsule. Pantothenic acid is a B vitamin that plays a role in energy production and the metabolism of fats and proteins in your body.

The capsule itself is made from gelatin.

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 Pantothenic Acid's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Supports energy metabolism.
  • We looked for evidence on: Chronic fatigue syndrome (CFS), Athletic performance.
  • The closest evidence on file: Pantothenic Acid is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Pantothenic Acid is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS).

Pantothenic acid is effective for treating pantothenic acid deficiency. For other uses—radiation dermatitis, hay fever, hair loss, and alcoholism—the evidence isn't strong enough for us to rate how well it works.

If you're considering this supplement for one of those conditions, it's worth discussing with your doctor to weigh what evidence does exist.

The evidence, ingredient by ingredient Pantothenic Acid

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.

Pantothenic acid taken by mouth is generally well tolerated, with diarrhea reported as an occasional side effect. The safety data notes that normal dietary amounts and the doses found in prenatal vitamins are appropriate, but if you're considering high-dose supplements, check with your doctor first.

Pantothenic acid is rated likely safe in pregnancy and during breastfeeding at typical doses.
