HelloPharmacist Scorecard of Lion's Mane by Om Mushroom Superfood

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 Oct 8, 2026

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 0 of its 2 active ingredients.
  • “Certified Organic Mushroom Powder Blend” is a proprietary blend — the label gives one combined amount (2 Gram(s)) without saying how much of each component you get.

This product contains two active ingredients: Lion's Mane and a certified organic mushroom powder blend. Lion's Mane is the ingredient we hold interaction and safety data for, and the blend is listed as a group whose individual components are not broken out in our data.

The inactive ingredients listed are cellulose and myceliated oats. These are inactive ingredients, not active ones, and their role in the capsule is not described in our data.

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: mental clarity, focus, alertness and cognition support.
  • We looked for evidence on: Cognitive function, Cognitive impairment, Memory, Attention, Alertness, Mental clarity — and 1 related terms.
  • The closest evidence on file: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Cognitive function (Natural Medicines).
  • Also on file: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Cognitive impairment, Memory.

Every effectiveness rating we hold for Lion's Mane is Insufficient Reliable Evidence To Rate. That covers Alzheimer disease, anxiety, athletic performance, cancer, cognitive function, and cognitive impairment.

In other words, reliable evidence for any of these uses is not established in the data we hold.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 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.

Our safety notes advise avoiding this product during pregnancy and while breastfeeding, because there is not enough safety data to say otherwise. Talk with your own doctor or pharmacist about your individual situation.
