Micro Fine Vitamin A Supplement for Reptiles and Amphibians. Contains Preformed Vitamin A as well as natural ingredients which provide beta carotene. INFORMATION: Preformed Vitamin A (Retinol) is an essential fat soluble vitamin that in nature comes from animal sources only. Plant sources of Vitamin A such as Beta Carotene and other Carotenoids must be converted into this active animal form to be utilized by the body. Carotenoids can be converted into Retinol by some species given optimal conditions but it has been shown that deficiencies can develop if Preformed Vitamin A is not directly provided in the Retinol form. This Supplement provides Preformed Vitamin A in the form of a spray dried water dispersible Retinyl Acetate powder in combination with natural sources of Beta Carotene derived from algae. INGREDIENTS: Calcium Carbonate, Fructose Powder, Cellulose Powder (as carriers), Chlorella Algae, Spirulina Algae, Calcium Propionate, Retinyl Acetate, Rosemary and Mixed Tocopherols (as preservatives).
