Understanding Vitamin D3 Supplement Quality
Choosing a high-quality vitamin D3 supplement involves several factors. The form of vitamin D is important. Cholecalciferol (D3) is preferred over ergocalciferol (D2) due to its better bioavailability.
It is also important for the product to be verified by a third party, such as ConsumerLab.com, USP, or NSF. These certifications guarantee the supplement contains the ingredients and dosages listed on the label. Many brands suspend their D3 in an oil base, such as MCT or olive oil, because vitamin D is fat-soluble. Combining D3 with vitamin K2 is a feature in several high-end supplements because K2 helps direct calcium to the bones.
