Most collagen supplements don’t work as well as they could because they’re difficult to use consistently — or they rely on forms the body first has to break down.
Barku is different. It uses hydrolyzed Type I, II, and III collagen peptides in a daily liquid format, combined with hyaluronic acid, glucosamine HCl, and vitamin C to support skin, coat, joints, connective tissue, and everyday comfort.
It’s the kind of formula I’d recommend for owners who want long-term daily support, not just another chew their dog eventually refuses.
