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. Glutathione is a compound your body makes naturally — it's made up of three amino acids (the building blocks of protein) linked together.
The inactive ingredients are vegetable cellulose, gelatin, silica, vegetable magnesium stearate, and vanilla, which give the capsule its structure and taste.
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 chemotherapy drug cisplatin.
For nonalcoholic fatty liver disease, Alzheimer disease, athletic performance, and cataracts, there isn't enough reliable evidence in our data to say whether it works. Talk with your doctor about what the research shows for your specific reason for considering it.
How safe is it?
Well-documented data
Oral glutathione appears generally well tolerated in the short term, but we don't have solid long-term safety data. During 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. One note: if you have asthma and were ever to use inhaled glutathione, it can narrow airways and cause shortness of breath or cough, but this product is a capsule taken by mouth, so that's not a concern here.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we checked. Still, talk with your pharmacist or doctor before adding this to any medications you take — they know your full health picture and can spot any concerns we might have missed.
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 may be worth considering if you're looking for support with nerve damage from cisplatin chemotherapy, though the evidence is still developing. If you're pregnant, breastfeeding, or take any medications, talk with your doctor or pharmacist before starting — they can help you weigh the limited safety data and check whether it's right for you.
