Niacin, Riboflavin, Pantothenic Acid, and Overall Cellular Health
The B‑vitamin complex includes several members — such as niacin (B3), riboflavin (B2), and pantothenic acid (B5) — that play crucial, interconnected roles in cellular metabolism, energy production, and general tissue maintenance. In a horse’s body, these vitamins act as cofactors for enzymes responsible for converting carbohydrates, fats, and proteins into usable energy. This metabolic support underlies muscle function, organ maintenance, immune competence, and overall vitality.
Riboflavin is essential as a precursor to coenzymes (FAD and FMN) that power oxidative metabolism — a process critical for delivering energy to tissues during both rest and activity. Pantothenic acid, necessary in forming coenzyme A (CoA), enables pathways responsible for fat metabolism and hormone synthesis. Niacin contributes to the synthesis of NAD/NADP, crucial electron carriers in metabolic reactions that support energy balance, cell maintenance, and even tissue repair.
Given these foundational roles, optimal levels of these vitamins are essential not just for athletic performance but for basic cellular health. While many horses receive adequate amounts via forage and hindgut microbial synthesis, those under heavy workload, frequent training, or metabolic stress (e.g., competition, fluctuating feed intake) may benefit from dietary supplementation to maintain metabolic efficiency. Ensuring the full B‑vitamin complex is available can enhance muscle recovery, support organ function, and help maintain steady energy levels rather than relying solely on carbohydrate/grain load.
