Spotting a good one on the shelf
Look for
- Look for 'Liposomal glutathione' on the label (the liquid one)
Watch out for
- Liposomal products that don't say how much glutathione is in each serving
- Skin-whitening products that promise dramatic results
Check with your provider first if…
- You have asthma. Don't breathe in glutathione (as from a nebulizer), since it has tightened the airways in some people.
- You have cancer or are in cancer treatment. Ask your oncology team first.
- You're pregnant or breastfeeding (not well studied)
- An upset stomach or a sulfur taste are the most common side effects
