Understanding vitamin d
What it does
Vitamin D helps the body absorb calcium and phosphorus, making it essential for building and maintaining strong bones. It also plays a role in muscle function and the immune system. It is unusual among vitamins because the skin can make it from sunlight.
When intake falls short
Low vitamin D is common, since few foods contain much of it and sun exposure varies with season, skin tone and lifestyle. Severe deficiency causes rickets in children and soft, weak bones, called osteomalacia, in adults. Older adults, people with darker skin, those who cover up or stay indoors, and exclusively breastfed infants are at higher risk.
Absorption & pairing
Vitamin D is fat-soluble, so taking it with a meal that contains some fat improves absorption. Because it works hand in hand with calcium, the two are often paired for bone health.
Food-first strategy
Few foods are naturally rich in vitamin D, so lean on fatty fish like salmon, sardines and trout, egg yolks, and fortified foods such as milk, plant milks and cereal. A serving of salmon can supply a full day's 20 mcg, or 800 IU, Daily Value. Sensible sun exposure and, when needed, supplements help fill the gap.
