Glycine propionyl-l-carnitine (GPLC) is a salt of propionyl-L-carnitine and glycine. It is a carnitine derivative, not a glycine supplement. Its structure improves carnitine absorption and delivery to tissues.
GPLC is used for workout recovery. It can reduce muscle soreness and support blood flow by boosting nitric oxide production. It also promotes healthy endothelial function and circulation.
Typical daily doses range from 1 to 3 grams. Take it before exercise or with meals to reduce stomach upset.
Side effects include mild stomach discomfort, especially at higher doses. People with kidney disease, or those who are pregnant or nursing, should consult a doctor before use.
