HelloPharmacist Scorecard of Tivose by Nutramax Laboratories Consumer Care

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 17, 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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Tivose contains one active ingredient: MaitakeGold 404 Mushroom extract, a concentrated form of maitake mushroom. The capsule also holds inactive ingredients—microcrystalline cellulose (a binder) and hydroxypropylmethylcellulose (a capsule material)—in amounts less than 2% each.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: support immune defenses and healthy immune function.
  • We looked for evidence on: immune response, infection resistance, antimicrobial defense, immune modulation.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for maitake mushroom's effectiveness isn't established for the conditions we've reviewed. The data we hold rates its use for hay fever, chemotherapy-related anemia, laryngeal cancer, chemotherapy-related diarrhea, and chronic fatigue syndrome as having insufficient reliable evidence to rate.

That means the research to prove or disprove it works for these uses isn't there yet.

The evidence, ingredient by ingredient Maitake 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.

Maitake mushroom is generally well tolerated when taken by mouth as a food or supplement, though the full safety profile of concentrated supplements hasn't been completely studied. The most common side effects reported in clinical trials were gastrointestinal—diarrhea and stomach pain (epigastric pain)—and a small number of participants reported nausea.

One person experienced a rash and itching after two doses, which cleared on its own without treatment. The safety data advises against using concentrated maitake supplements during pregnancy or while breastfeeding because there isn't enough data to know either way.

Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or nursing.

MaitakeGold 404 Mushroom extract3 drug types · 260 drugs

Antidiabetes Drugs

Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that maitake mushroom can lower blood pressure.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.
In a case report, a patient previously stabilized on warfarin developed an elevated international normalized ratio (INR) of 5.1 after taking maitake mushroom (Grifron-Pro Maitake D-Fraction) 1 drop/kg daily in three divided doses for one week. The elevated INR resolved after holding warfarin for two days, then reducing the dose by 11%. It is thought that the beta-glucan constituent of maitake mushroom might cause warfarin dissociation from proteins, resulting in increased free warfarin levels and increased warfarin effects.
