Niacinamide is included as part of Prebiotic's skin barrier nutrients active ingredients.
Vitamin B3, also known as niacinamide, supports your dog's skin barrier function, coat condition, and cellular energy metabolism. It plays a role in epidermal renewal and helps the skin hold on to moisture and resist irritation, which is why it sits alongside the fibre blend in Prebiotic: one supports the gut, the other supports the skin, and the two are more connected than they look.
