HelloPharmacist Scorecard of Full Spectrum Japanese Ashitaba 500 mg by Swanson

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 Aug 6, 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.

This product contains one active ingredient: 500 mg of Japanese Ashitaba per capsule. Ashitaba is a plant traditionally used in Asian cuisines and herbal medicine.

The capsule itself is made from gelatin and filled with microcrystalline cellulose, magnesium stearate, and silica—common inactive ingredients that help form and preserve the capsule.

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 Ashitaba product and its label doesn't state a use — see Ashitaba'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 on ashitaba for alcohol-related liver disease is insufficient to rate its effectiveness. We don't yet have reliable research showing whether it works for this purpose, so we can't say whether it would help you.

The evidence, ingredient by ingredient Ashitaba

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 0 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.

Ashitaba is likely safe when eaten as a food, but safety data on concentrated supplements is limited. The safety data we have advises against using ashitaba supplements during pregnancy and while breastfeeding because there isn't enough research to know whether it's safe for your baby.

If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking this product.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Ashitaba.
  • The most serious interaction on file is rated Moderate.
  • For scale: 186 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.

Before taking this ashitaba supplement, check with your doctor or pharmacist if you take any medications that your liver breaks down through the CYP1A2 enzyme—including certain heart, psychiatric, cancer, and pain medications. This interaction hasn't been seen in patients yet, but ashitaba may slow how quickly your body clears these drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Ashitaba is a plant supplement with limited evidence for its health effects. Its main concern is a possible interaction with medications your liver processes through the CYP1A2 enzyme—a fairly large group.

If you take any prescription or over-the-counter drugs, check them against this product before you start, and discuss it with your doctor or pharmacist to make sure it's right for you.

Cytochrome P450 1A2 (Cyp1A2) Substrates

In vitro research shows that ashitaba extract inhibits cytochrome P450 (CYP) 1A2. Theoretically, concomitant use of ashitaba with CYP1A2 substrates might decrease the clearance of these substrates and increase the risk for adverse effects. However, this interaction has yet to be reported in humans. Until more is known, use with caution.
