Nutrition for Aging: Vitamin D
Are you getting enough of this important vitamin?
We need many essential nutrients for long, healthy lives. But most adults in the U.S. get less vitamin D than recommended. When you get older, it's really important to have the right amount of vitamin D. It protects your bone, joint, and muscle health.
Learn the risks of not having enough vitamin D, and where to get it.
What can a vitamin D deficiency cause?
If you don’t have enough vitamin D, you could have vitamin D deficiency. That means your body won’t absorb calcium well. It can also lead to illnesses such as osteoporosis or rickets.
What can cause Vitamin D deficiency?
Lack of vitamin D in your diet or problems absorbing vitamin D from food
Not enough sunlight
Problems in liver or kidneys converting vitamin D
Medicines that interfere with absorbing vitamin D
How much is enough?
The amount of vitamin D needed varies for each person. Most adults need 600 IU (international units) each day. But adults aged 71 and over need 800 IU. You might be at risk of vitamin D deficiency if you’re in one of these categories:
People with osteoporosis, liver disease, chronic kidney disease, obesity, Crohn’s disease, hyperparathyroidism, and some types of lymphoma
People with dark skin
People who take certain medicines that impact vitamin D metabolism
Where do you get vitamin D?
Bodies naturally create vitamin D after sunlight exposure. Another way to get more is through your diet. Try these foods to boost your vitamin D:
Fatty fish such as salmon, tuna, and mackerel
Milk (fortified: nonfat, 1% or 2%, 1%, or fat-free)
Remember: Don’t forget to read your food label to ensure your foods have plenty of vitamin D. Vitamin D is considered a “voluntary” nutrient. It is not included on every food label. It is only included when it is “added” to a food.
Ask your doctor for a vitamin D test to learn if you need supplements. Make sure you record any vitamins or supplements you take in My HealtheVet. You can download and share this information with your provider at future appointments.
