Vitamins: Small But Mighty Nutrients.
They’re organic compounds — carbon-based substances found in natural, living things — required in tiny amounts for vital functions like immunity, metabolism, nerve signalling, recovery, and more.
They’re needed in far smaller amounts than other nutrients such as energy, protein, or water — and while they don’t directly provide energy or build tissue, they’re deeply involved in keeping every system running.
Their function, and their relationship with minerals and each other, means a consistent daily supply is essential.
The word ‘vitamin’ is often misused to mean ‘nutrient’ — but it’s actually just one class of nutrients. It doesn’t include other essential nutrients such as minerals, protein, fats, water etc.
Some vitamins can be made by the horse — like Vitamin C in the liver or Vitamin D in the skin from sunlight. Others are made by gut microbes — like the B-complex and Vitamin K — though how much is actually absorbed and used by the horse isn’t fully understood.
💡 While the horse’s hindgut has huge potential for vitamin synthesis, factors like stress, gut
health, and modern feeding practices may disrupt this balance.
📉 Vitamin status can be influenced by: -
• Forage quality and freshness
• Sunlight exposure (Vitamin D)
• Gut health and microflora
• Feed processing or storage
• Stress and illness
• Exercise and workload
• Age or life stage
• Medications (like antibiotics)
• Individual metabolic variation
🧠 Some vitamins are stored, some are made by gut microbes, some are synthesised by the body, and some must come from the diet.
Vitamins don’t work in isolation — they work in synergy with each other, with minerals, and within every major system of the body.
✨ Synergy is the biochemical version of mateship — a group of nutrients supporting each other to help the horse thrive.
More isn’t always better. But neither is guessing.
