3. Additional Ingredients
Some vitamin D supplements may include additional nutrients, such as calcium or magnesium, which can enhance vitamin D’s effectiveness.
4. Absorption
Consider supplements that improve absorption, such as soft gels or liquid formulations, especially for individuals with digestive issues.
