Vitamins and minerals can interact in ways that influence how they are absorbed and used in the body. For example, vitamin D3 and vitamin K2 are often paired because they work together in the body, and B vitamins are commonly included as a group due to their complementary roles. Some minerals, like calcium and iron, can interfere with the absorption of other nutrients or require different timing, which is why they are not included in Well Daily. The formula is designed with these interactions in mind to support effective absorption and a more balanced daily approach.
