HelloPharmacist Scorecard of L-Glutathione 250 mg by Wonder Laboratories

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

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: L-glutathione, a compound your body naturally produces that plays a role in cellular protection and detoxification. The capsule itself is made from vegetable cellulose and gelatin, with silica, vegetable magnesium stearate, and vanilla as inactive ingredients.

Does it work?

Moderate 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

This product doesn't appear to be marketed for a specific use, so we graded Glutathione's overall clinical evidence instead.

Moderate

Some clinical evidence supports Glutathione for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Cisplatin-induced neurotoxicity — rated "Possibly Effective" (Natural Medicines).

The evidence here is mixed. L-glutathione shows possibly effective support for reducing nerve damage (neurotoxicity) from the chemotherapy drug cisplatin.

For everything else in this product—nonalcoholic fatty liver disease, Alzheimer's disease, athletic performance, and cataracts—we don't have enough reliable evidence to rate whether it works. That doesn't mean it doesn't; it means the science isn't settled yet.

The evidence, ingredient by ingredient Glutathione

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.

Oral L-glutathione appears generally well tolerated in short-term use. The long-term safety of oral forms and the safety of inhaled or IV versions are less clear.

One important note: if you have asthma, inhaled glutathione can trigger airway narrowing and shortness of breath—but this product is a capsule, so that risk doesn't apply here. For pregnancy, there isn't enough reliable safety information, so it's best avoided unless your doctor advises otherwise.

The same goes for breastfeeding—the data isn't there to say it's safe, so caution and avoidance are advised. Talk with your doctor or pharmacist about whether it's right for you in these situations.

Side effects, ingredient by ingredient Glutathione

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredient we could check. That said, talk with your doctor or pharmacist before you start, particularly if you take any prescriptions or have plans to get pregnant or breastfeed.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.

L-glutathione may be worth considering if you're looking for support with chemotherapy-related nerve damage and have your doctor's okay. If you're pregnant, breastfeeding, or take any medications, check in with your doctor or pharmacist first—especially since long-term safety data is still limited.

This is one to discuss before starting.

L-Glutathione 250 mg by Wonder Laboratories: Common Questions

Does L-Glutathione 250 mg by Wonder Laboratories interact with any medications?
We do not currently list a known interaction for the mapped ingredients in L-Glutathione 250 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
L-Glutathione 250 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is L-glutathione safe to take long-term?
Short-term oral use appears generally well tolerated, but we don't have clear safety data for long-term use. If you're thinking of taking it regularly for more than a few weeks, it's worth checking in with your doctor or pharmacist about what we do and don't know.
Does this work for liver health?
L-glutathione is studied for nonalcoholic fatty liver disease, but we don't have enough reliable evidence yet to say whether it actually helps. The science on this one isn't settled.
Can I take this while pregnant or breastfeeding?
There isn't enough reliable safety information to know either way, so both pregnancy and breastfeeding are situations where you should talk with your doctor or pharmacist before taking it. They can help you weigh the unknowns for your situation.
What does L-glutathione do in your body?
Your body makes it naturally—it's involved in cellular protection and detoxification. This supplement provides an oral dose, though how much of it your body actually absorbs and uses isn't fully clear.
Is this capsule free of fillers?
The capsule itself is made of vegetable cellulose and gelatin, with silica, vegetable magnesium stearate, and vanilla added as inactive ingredients. So no, it does contain other ingredients besides L-glutathione.
