D Vitamin![]() |
||||
Vitamin D is a fat-soluble vitamin. It is stored in the body and can reach toxic levels if consumed in excess.
Consuming more than four times the Daily Value of vitamin D can produce diarrhea, dermatitis, headaches, nausea, and weakness to irreversible kidney damage, and calcium deposits in soft tissues such as the blood vessels or heart.
Infants, children, and pregnant women are most sensitive to excessive vitamin D intake.
Prolonged exposure to sunlight does not cause toxic levels of vitamin D.
The Daily Value for vitamin D is 400IU.
Dietary intake if vitamin D is not necessary in healthy, young persons frequently exposed to sunlight.
People who rarely go outdoors, wear heavy clothing, or live in smoggy or overcast areas must rely on food for this vitamin.
Sunscreen lotions might block the skin's ability to make vitamin D.
The body is less capable of making vitamin D as people age, so dietary sources become more important to meet daily needs.
