The formula

Biotin & Zinc Coat Chews, and why it is built this way

A micronutrient formula rather than an oil: biotin, zinc chelate, vitamin E and methionine, aimed at the keratin and sebum side of coat condition. Useful where fish oil alone has not moved the needle.

No brewer's yeast (a common itch trigger), no artificial colours.

What it does

Three things you can expect

01

Supports coat regrowth

Biotin and methionine are rate-limiting for keratin synthesis.

02

Zinc in a chelated form

Better absorbed than zinc oxide, and gentler on the stomach.

03

Pairs with omega-3

Works on structure while oil works on the lipid barrier.

Questions

Before you buy

Can too much biotin be harmful?
Biotin is water-soluble and excess is excreted. The bigger risk is zinc oversupplementation — do not stack with another zinc product.
Will it help bald patches?
Only if the cause is nutritional. Hair loss from thyroid disease, mites or allergies needs diagnosis, not supplements.
Is it safe long term?
Yes at the stated dose. We suggest a vet check if you are using it for more than six months.
