Overview
Vitamin D is a crucial nutrient for pets, playing a vital role in calcium and phosphorus regulation, which is essential for healthy bones and immune function. While beneficial, it must be administered carefully to avoid toxicity.
How It Works
Vitamin D helps regulate calcium and phosphate balance in the body, supporting bone health and facilitating normal immune system functions. It aids in the absorption of calcium in the intestines and maintains adequate serum calcium and phosphate concentrations for bone mineralization.
Uses & Indications
- Support bone health
- Improve immune function
- Aid in calcium absorption
