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 product contains one active ingredient: agaricus mushroom extract in a 4:1 concentrated powder form. There are no inactive ingredients listed.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Agaricus Mushroom product and its label doesn't state a use — see Agaricus Mushroom's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for agaricus mushroom doesn't yet support claims for hay fever, osteoporosis, cancer, heart disease, chemotherapy side effects, or Crohn disease — there's simply insufficient reliable evidence to rate how well it works for any of these. If you're considering it for one of these uses, the science isn't established in our data.

The evidence, ingredient by ingredient Agaricus Mushroom

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.

Agaricus mushroom is generally well tolerated when taken by mouth. The most common side effects are mild: abdominal discomfort, diarrhea, and nausea.

Rare serious effects — allergic reactions, liver damage, and lung inflammation — have been reported; three cases of severe liver damage occurred in women with cancer undergoing chemotherapy who also took agaricus supplements, and allergic skin reactions have been documented in individual users. During pregnancy, there isn't enough safety data; the advice is to avoid supplement doses.

The same holds for breastfeeding — avoid it until more is known. Supplement safety and long-term effects overall aren't well established.

Why this rating?

  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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 before taking if you use antidiabetes drugs — oral medications or insulin. The risk of low blood sugar is Moderate but real.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take medication for diabetes, this product needs a careful check with your pharmacist or doctor first — low blood sugar is a real risk. For other uses, the evidence isn't there yet.

If you're pregnant or breastfeeding, skip it until you've talked with your doctor.
