What to know
Your body makes its own glutathione from three amino acids, and cysteine is the one most likely to run short. Glutathione taken by mouth is partly broken down in digestion, so how much reaches the cells is still debated. That is the reason this formula includes cysteine as well. Check the label for the amount of each ingredient per capsule. Sulfur ingredients have a natural smell, which is normal.
Who should check first
- Asthma: speak to your doctor before taking cysteine or glutathione supplements.
- Kidney stones (cystine type): do not take cysteine without your doctor's advice.
- Pregnant, breastfeeding or on medication: check with your doctor or pharmacist first.
