Thiamine Mononitrate (Vitamin B1) in Pet Food

Grade A0 pts deductedNutrients

What It Is

"A stable, synthetic form of vitamin B1 added to meet AAFCO nutrient profiles."

Health Impact

Thiamine is one of the most heat-fragile vitamins in raw meat and grains — extrusion and canning destroy a significant share of what's naturally present, which is exactly why this stabilized synthetic form exists: it survives processing reliably where the natural vitamin would not. Thiamine deficiency causes serious neurological problems in cats especially, so this is a critical, not cosmetic, addition.
