The AI for sodium is 1,500 mg per day for adults up to age 50, 1,300 mg per day

for those between 50 and 70, and 1,200 mg per day for those 70 and older

Consuming excess amounts of vitamin D can cause too much calcium

absorption. Taken over weeks or months, excess vitamin D can lead to unwanted

calcification of the heart, kidneys, and blood vessels in adults and can harden

children’s bones at too early an age. Adult intakes of vitamin D above 100 mcg

(4,000 IU) per day may be helpful in certain cases but aren’t recommended

without medical supervision.

In developing countries where diets are severely limited and centered on breads

or rice, many children and adults become blind due to insufficient vitamin A.
