Combination formulas are dietary supplements that blend multiple nutrients—such as vitamins, minerals, amino acids, herbs, or other compounds—into a single product. These formulas are designed to support overall health by targeting specific areas, such as immune function, energy levels, joint health, or cognitive function. By combining complementary ingredients, these supplements can provide more comprehensive benefits than individual nutrients alone. Common examples include multivitamins, joint support blends, or energy-boosting formulas. They offer a convenient way to address multiple health goals with one supplement.
