HelloPharmacist Scorecard of L-Glutathione 100 mg by Swanson
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 capsule contains one active ingredient: Setria Glutathione, a form of glutathione at 100 mg per dose. Glutathione is a naturally occurring compound your body makes; it functions as an antioxidant—essentially a cleanup crew for harmful molecules called free radicals.
The inactive ingredients are rice flour, gelatin, and calcium laurate, which are there to hold the capsule together and help it work.
Does it work?
Couldn't assess
The evidence for glutathione is mixed. It's rated possibly effective for reducing nerve damage (neurotoxicity) caused by cisplatin, a chemotherapy drug.
For other uses—nonalcoholic fatty liver disease, Alzheimer disease, athletic performance, and cataracts—the evidence we hold is insufficient to say whether it works. If you're considering it for one of those conditions, talking it over with your doctor will help you weigh what the research says so far.
How safe is it?
Well-documented data
Oral glutathione appears generally well tolerated in short-term use, but long-term safety data are limited. If you have asthma, know that inhaled glutathione can narrow your airways and cause shortness of breath or cough, though this capsule is taken by mouth, not inhaled.
During pregnancy, there isn't enough reliable safety information, so it's best avoided unless your doctor advises otherwise. The same applies to breastfeeding—the data aren't there to know either way, so talk with your doctor or pharmacist for personalized advice.
Meds to double-check
No known interactions
No interactions are documented in our data for the medications we checked. Run your own list through the search tool on this page to confirm.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Swanson's L-Glutathione may be worth a conversation if you're dealing with cisplatin side effects or curious about antioxidant support. Because long-term safety isn't well established and pregnancy or breastfeeding data are thin, check in with your doctor or pharmacist before starting—especially if you're in either of those situations or take medications regularly.
