Vitamins and minerals are often marketed as coat “boosters,” but they’re also the easiest place to overdo it. A complete and balanced diet already supplies many essentials, and adding multiple overlapping products can create unnecessary excess. More importantly, some vitamin-mineral supplements may not meet minimum nutritional recommendations, meaning you can’t assume a label equals adequacy (RVA, 2021).
For shedding-focused goals, think of micronutrients as supporting cast, not the star. If you want a coat that looks vibrant, choose a formula built for skin-and-coat presentation, then evaluate the visible signals: softness, shine, and reduced flaking. Keep the routine simple enough to maintain.
