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, a compound your body makes naturally and uses in cells to protect against damage and support immune function. Wonder Laboratories delivers 250 mg per capsule in an oral form.
The capsule also contains inactive ingredients (vegetable cellulose, gelatin, silica, vegetable magnesium stearate, and vanilla) that help hold and deliver the glutathione.
Does it work?
Moderate evidence
The evidence for L-glutathione is mixed. It's rated possibly effective for reducing nerve damage caused by the chemotherapy drug cisplatin, but for other uses — nonalcoholic fatty liver disease, Alzheimer disease, athletic performance, and cataracts — the data we hold shows insufficient reliable evidence to rate it.
That means we don't have enough solid proof one way or the other.
How safe is it?
Well-documented data
Oral L-glutathione appears generally well tolerated in the short term, though long-term safety hasn't been firmly established. One important note: if you have asthma, you should know that inhaled (nebulized) glutathione can narrow airways and cause shortness of breath and cough — but this product is oral, not inhaled, so that risk doesn't apply here.
For pregnancy and breastfeeding, there isn't enough reliable safety information. The safety data advises against use during pregnancy unless your doctor advises otherwise, and caution or avoidance is advised during breastfeeding.
Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or breastfeeding.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. Use the search tool on this page to verify your specific medications, and confirm with your own doctor or pharmacist before starting.
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 to support your body's natural antioxidant system, especially if you're dealing with cisplatin-induced nerve damage and your doctor thinks it might help. No interactions are documented for this ingredient, but check your exact medications with the search tool before you start, and talk with your doctor or pharmacist — they'll help you decide if it's a fit for you.
