Vitamin C and D3 are supported by strong evidence for maintaining immune function and respiratory health. B vitamins, including B1, B2, and Niacin, play essential roles in energy metabolism and cellular function. Overall, these ingredients are well-studied, though the specific combination in this formula has limited evidence coverage.

Echinacea Goldenseal Berberine Vitamin C B-Complex Astragalus Mushroom Complex Black currant

Immune Factors is an extremely comprehensive blend of nutrients, botanicals and mushrooms to support a healthy immune system. Immune Factors begins with our high potency B-complex, along with our non-acidic vitamin C - all of which are essential for a healthy immune system. They are also not readily available from the diet and easily depleted by stress and life. We add two standardized extracts of echinacea, along with extracts of goldenseal, berberine, astragalus and black currant. All of these plant-based extracts have been used for centuries to optimize immune system function and modern research has validated their benefits. We also add our unique, proprietary blend of organic immune supportive mushrooms, including turkey tail, reishi, chaga, maitake, shiitake, cordyceps, and agaricus. The combined benefits of all these remarkable ingredients make Immune factors a uniquely powerful opportunity to naturally support immune system function.

Contains no additives or common allergens Contains no milk, soy, yeast, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
