Glycine
A direct building block of glutathione — your liver's master antioxidant. Part of Shield's triple glutathione strategy (glycine + broccoli seed + selenium).
What glycine does for your liver
Glutathione — your liver's most important antioxidant — is made from three amino acids: cysteine, glutamate, and glycine. In Libertia Lite, we use NAC (which provides cysteine) to build glutathione. In Shield, we use a different approach.
Shield's triple glutathione strategy works like this: glycine provides one of the three direct building blocks, broccoli seed extract switches on your body's own glutathione production pathway (Nrf2), and selenium powers the enzymes that use glutathione.
This alternative approach avoids NAC (reserved for Lite) while still effectively supporting glutathione levels through a complementary pathway. Glycine also has mild calming and liver-protective effects of its own.
Best timing for maximum benefit
Foods that help or hinder absorption
Glycine is found in protein-rich foods (meat, fish, dairy, legumes) and is also produced by your body. Supplementation adds to what you already have.
Medicines to discuss with your doctor
If you take any of these medicines, talk to your doctor first
What you might experience
What you might experience
Glycine at 300–600mg daily is very well tolerated. It's a naturally occurring amino acid present in food. Mild drowsiness has been reported occasionally — which some people consider a benefit rather than a side effect. Stomach discomfort is rare.
Duration of use
Indefinite. Glycine is a natural amino acid safe for long-term daily use.
Situations where this ingredient is not appropriate
On clozapine: Glycine may interact with clozapine. Consult your psychiatrist.
