What is your vitamin balance? Is there any vitamin deficiencies to pay attention to? Vitamins allow your body to grow and develop. They also play important roles in bodily functions such as metabolism, immunity, and digestion. At Silverberry, we examine your genes to discover whether you have a predisposition for a deficiency in 17 essential vitamins — including vitamins A, C, D, E, K and B vitamins (such as riboflavin and folate). Learn how your genetic variations may influence your body’s processing and absorption of vitamins.
