If you’re looking to support your body’s glutathione production and antioxidant defenses, this provides the key building block. At one tablet, you're getting 500 mg of **L-Cysteine** — just below the 600 mg minimum used in clinical research. Following the label's suggestion of 1–3 tablets daily puts you at 500–1,500 mg, comfortably within the studied range for supporting liver health and antioxidant capacity.
You're also getting 60 mg of **Vitamin C** and 10 mg of **Vitamin B6**, both of which play supporting roles in cysteine metabolism and glutathione recycling. These are modest doses — well below their own clinical ranges — so think of them as functional co-factors rather than standalone contributors.
One thing worth knowing: if you're supplementing for glutathione support, most clinical research actually uses NAC (N-Acetyl-L-Cysteine), which is more stable and better studied. Free-form L-Cysteine is less researched as a standalone supplement, so the evidence base here is thinner than the dose alone might suggest.
