Which Vitamins Are Americans Lacking?

Research from Oregon State University discovered that 96% of Americans are likely not getting enough Vitamin D. Vitamin D is important for bone health and the immune system, and can be acquired through sunlight or by eating foods like fish and beef. Just over half of Americans are deficient in Vitamin A and calcium, and 43% need more Vitamin C. Scurvy, a disease that can cause bleeding gums and loose teeth, is caused by Vitamin C deficiency.
