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.
What’s inside
Full disclosure
This product contains one active ingredient: L-glutathione at 250 mg per capsule. L-glutathione is a small protein made naturally in your cells that acts as an antioxidant — it helps protect cells from damage and supports your body's detoxification processes.
The inactive ingredients — vegetable cellulose, gelatin, silica, vegetable magnesium stearate, and vanilla — are fillers and capsule materials that don't contribute to the supplement's active effects.
Does it work?
Moderate evidence
The evidence for L-glutathione is mixed and depends on what you're taking it for. It's rated possibly effective for reducing nerve damage (neurotoxicity) caused by the cancer drug cisplatin.
For nonalcoholic fatty liver disease, Alzheimer disease, athletic performance, and cataracts, the evidence isn't strong enough to rate — we simply don't have reliable data yet to say whether it works for those uses.
How safe is it?
Well-documented data
Oral L-glutathione appears generally well tolerated in the short term, though long-term safety data is limited. One important note: if you have asthma and use inhaled (nebulized) glutathione, it can narrow your airways and cause shortness of breath or cough — but this product is a capsule, so it's taken by mouth, not inhaled.
For pregnancy and breastfeeding, the safety data is too thin to know either way. The facts advise against use during pregnancy unless your doctor specifically recommends it, and caution or avoidance during breastfeeding.
Talk with your doctor or pharmacist about whether this product is right for you in either situation.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, it's always smart to confirm with your doctor or pharmacist that this product won't interfere with your specific medications before you add it to your routine.
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 250 mg is a single-ingredient antioxidant supplement with no documented drug interactions. It may help reduce nerve damage from cisplatin chemotherapy, though evidence for other uses is still unclear.
If you're pregnant, breastfeeding, or taking any medications, check with your doctor or pharmacist before starting.
