HelloPharmacist Scorecard of Glutathione-SR by Thorne
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: glutathione, a compound your body makes naturally and uses to help protect cells from damage. Glutathione-SR is formulated as a sustained-release capsule, designed to release the ingredient gradually.
The inactive ingredients are hydroxypropyl methylcellulose, magnesium citrate, calcium laurate, hypromellose, leucine, and silicon dioxide — standard capsule materials and binders.
Does it work?
Not established
The evidence for glutathione is mixed. It's possibly effective for reducing nerve damage (neurotoxicity) caused by the chemotherapy drug cisplatin.
For nonalcoholic fatty liver disease, Alzheimer disease, athletic performance, and cataracts, the evidence we have isn't strong enough to say whether it works. More research is needed in those areas.
How safe is it?
Well-documented data
Oral glutathione appears generally well tolerated over the short term, but long-term safety data are limited. If you have asthma, be aware that inhaled (nebulized) glutathione can narrow airways and cause shortness of breath or cough — this product is oral, not inhaled, but it's worth knowing if you've had that reaction before.
During pregnancy, the safety data aren't reliable enough to know either way, so the safety notes advise caution and avoidance unless your doctor advises otherwise. The same applies to breastfeeding — there isn't enough information to know if it's safe, so caution and avoidance are advised.
Meds to double-check
No known interactions
No interactions are documented in our data for glutathione. That said, be sure to run this product through the checker on this page with your complete medication list before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
Glutathione-SR may be worth considering if you're undergoing cisplatin chemotherapy and looking to reduce nerve damage, though talk it over with your oncologist first. If you're pregnant or breastfeeding, the data aren't clear enough to say it's safe — check with your doctor or pharmacist before using it.
And because long-term safety isn't well studied, it's worth a conversation with your own healthcare provider about how long you plan to take it.
