New research published this week in JAMA indicates that there's been an increase in the amount of vitamin D adults are consuming, and it's much more than what's needed.
Vitamin D is essential in supporting bone health, and the current recommended daily allowance (RDA) for healthy adults is 600 IU. The study indicates, however, that there's been a significant jump in adults consuming more than 1,000 IU of vitamin D, some exceeding 4,000 IU. Additionally, most healthy adults already receive enough vitamin D through their diets and exposure to sunlight. Consuming large amounts of vitamin D can possibly cause negative side effects. The biggest risk being overabsorption of calcium in the system, which can lead to digestive issues and kidney stones.
If you're looking for quick and easy ways to receive vitamin D without overdoing it, getting outside in the sun is a surefire bet. Additionally, foods like fortified orange juice, milk, and cereals can help. Or turn to food sources that naturally contain vitamin D like salmon, eggs, and tuna.
