Vitamin D3 Supplement in Pet Food

Grade A0 pts deductedNutrients

What It Is

"Synthetic vitamin D3 (cholecalciferol) added to meet AAFCO nutrient profiles."

Health Impact

Dogs and cats can't synthesize enough vitamin D from sunlight the way humans can, so diet is their main source. Like vitamin A, natural D3 is heat-fragile, which is why it's added back as a stabilized supplement after cooking rather than relied on from raw ingredients. Standard and safe at labeled amounts.

Why This Grade
