HelloPharmacist Scorecard of Reduced L-Glutathione 250 mg by Solgar

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 at 250 mg per capsule. Glutathione is a naturally occurring compound made from three amino acids — it's an antioxidant your cells produce on their own, but levels can drop with age and certain health conditions.

The capsules also contain inactive ingredients (microcrystalline cellulose, vegetable cellulose, vegetable magnesium stearate, and silica) that help hold the capsule together.

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?
  • The label markets general wellness (“antioxidant support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • 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 for L-Glutathione is mixed and often limited. It's rated possibly effective for reducing nerve damage (neurotoxicity) caused by the cancer drug cisplatin, but the data for other common uses — fatty liver disease, Alzheimer's disease, athletic performance, and cataracts — is insufficient to say whether it actually works.

If you're considering it for cisplatin-related nerve damage, that's worth discussing with your oncologist; for other uses, 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 the short term, though long-term safety data is limited. The safety notes flag that you should avoid this supplement during pregnancy and breastfeeding unless your doctor says otherwise, because there isn't enough reliable information to know it's safe in those windows.

One caution: if you have asthma and ever encounter inhaled (nebulized) glutathione — a different form — it can narrow airways and cause shortness of breath or cough; this oral capsule doesn't carry that risk.

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 L-Glutathione with any medications. You're clear on the drug-interaction front — but that's not a green light to start without talking to your doctor or pharmacist, especially if you're pregnant, breastfeeding, or have asthma.

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.

If you're looking at glutathione for cisplatin-related nerve damage, this may be worth a conversation with your cancer doctor. For other uses, the evidence isn't strong enough yet to say it'll help.

Since it has no documented drug interactions, it's unlikely to clash with your medications — but run your full medication list past your doctor or pharmacist before you start, and skip it during pregnancy or breastfeeding unless you've checked with them first.

General Statements

Glutathione is a sulfur-containing peptide made up of three amino acids: Glutamic acid, Cysteine and Glycine. It is an important water-soluble antioxidant that plays a role in protecting the body from free radical oxidative stress, which can lead to premature aging of cells. It also acts in amino acid transport pathways.

Reduced L-Glutathione 250 mg by Solgar: Common Questions

Does Reduced L-Glutathione 250 mg by Solgar interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Reduced L-Glutathione 250 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Reduced 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.
Can I take this while I'm pregnant or breastfeeding?
The safety data advises against it — there isn't enough reliable information to know it's safe in pregnancy or while breastfeeding. Talk with your doctor or pharmacist before taking it if you're in either situation; they can help you weigh the pros and cons for your specific case.
What is L-Glutathione and why would I need it?
It's an antioxidant your body makes naturally from three amino acids, and it helps protect your cells from damage. Levels can drop with age or certain health conditions, which is why some people take it as a supplement — though the evidence for most uses is still developing.
Will this help with my athletic performance?
The evidence isn't established enough to say. The data we hold rates it as having insufficient reliable evidence for athletic performance, so whether it actually boosts your workout results isn't clear.
Is this safe to take long-term?
Short-term use appears generally well tolerated, but we don't have solid safety data on long-term use. If you're thinking of taking it regularly for months, check with your doctor or pharmacist first.
Do these capsules have a lot of fillers?
They're kept simple — just L-Glutathione as the active ingredient and four inactive ingredients (cellulose, magnesium stearate, and silica) that help form the capsule. No unnecessary additives.
