Why do vitamins have different values?
The values for converting IU to mcg (or vice versa) are different for each vitamin because the conversion factors depend on the molecular weight and potency of the vitamin.
For example, the conversion factor for Vitamin D is 0.025 mcg per IU, while the conversion factor for Vitamin A varies depending on whether it’s being converted from IU to mcg retinol or mcg beta-carotene. This is because Vitamin D has a lower molecular weight and higher potency than Vitamin A.
Similarly, the conversion factor for Vitamin E is 0.67 mg per IU because it has a higher molecular weight and lower potency compared to Vitamin D.
Overall, the conversion factors are based on the specific characteristics of each vitamin and are determined by scientific studies and regulatory agencies to ensure accurate dosing and safety.

Need help with your pet?
Do you have health issues that you cannot resolve with conventional therapies? Are you looking for a natural approach to help your pet live a long healthy life?
This is possible, and what I do. My approach is to restore the immune system in dogs and cats so they can achieve homeostasis. That is the best protection against pathogens that can lead to diseases.
