Brief Description: Don't like gut-loading insects, or want to be certain every vitamin need is met? Use R-Zilla spray-on Vitamin Supplement. It's as easy as a daily misting of a pet's food supply, then waiting fifteen seconds before serving. The mist contains vitamins C, B1, B2, B6, B12, D3, Niacin and folic acid. Vitamin A is included in the form of beta carotene, a natural plant-based supplement that allows a pet to absorb only the amount of the antioxidant it needs.
