It’s a sad fact that about one billion people worldwide have vitamin D deficiency. Roughly 50% of the world’s population has vitamin D insufficiency, and about 35% of adults in the United States are deficient in vitamin D. Now, vitamin D deficiency means that the body doesn’t have enough vitamin D. Failure to address the issue can cause a person to experience problems with bones and muscles.
That leads perfectly into the focal point of this article: osteoporosis. This condition is characterized by bones becoming fragile due to loss of tissue. That usually happens as a result of vitamin D deficiency or calcium deficiency. Osteoporosis affects about 10 million American adults over the age of 50. The likelihood of developing the condition after age 80 increases by 30% in men and 47% in women, according to a 2017 review of studies.
It’s no secret that musculoskeletal health is of major concern as you get older. Keeping muscles, tissues, and bones strong as you age can help you avoid osteoporosis, among other age-related conditions. Keeping up your vitamin D intake can help support your bones in the long run.
The Link Between Osteoporosis And Vitamin D
Vitamin D promotes the absorption of calcium in the gut and helps regulate healthy calcium concentrations within the body. The calcium in the body is used to maintain muscle strength and to mineralize bones, which can help prevent fractures. Because the body loses bone density as it ages, consuming adequate amounts of vitamin D and calcium is essential to support bone integrity.
A 2021 review in the International Journal of Molecular Sciences found that vitamin D deficiency accelerates bone turnover, loss, and fractures. It’s no surprise, then, that vitamin D deficiency is more prevalent in older adults with osteoporosis.
How To Avoid Vitamin D Deficiency As You Age
In order to maintain musculoskeletal health, especially as you age, you have to maintain optimal vitamin D levels. Since older age is a major risk factor for vitamin D deficiency, you have to be mindful of your levels, and those of older friends and loved ones. Health experts explain that the most effective way to maintain healthy vitamin D levels at any age is through quality supplementation. Before choosing a supplement, you must know how much you need. The amount you need each day depends on your age, and the recommended daily intake is listed in micrograms (mcg) and International Units (IU) below:
- Birth to 12 months: 10 mcg (400 IU)
- Children 1-13 years: 15 mcg (600 IU)
- Teens 14-18 years: 15 mcg (600 IU)
- Adults 19-70 years: 20 mcg (800 IU)
- Pregnant and breastfeeding teens and women: 15 mcg (600 IU)
What’s The Difference Between Vitamin D2 and D3?
When choosing a vitamin D supplement, make sure to check the label to determine if it is vitamin D2 or D3. D2 is the plant-based form of the vitamin and is commonly in fortified foods, such as orange juice and cereal. D2 is primarily sourced from fungi and yeast by exposing them to UVB radiation. If you are vegan or vegetarian, D2 is the optimal supplement choice. That said, several studies found that vitamin D3, which comes from fatty fish, is superior at boosting activated vitamin D levels in the blood. If you choose a D2 supplement, you may need a higher dose in order to raise blood levels. Check with your healthcare professional to determine how much you need.
The Takeaway
Now more than ever, take bone integrity and muscle strength seriously, especially if you are climbing the age ladder. Vitamin D deficiency can increase the risk of osteoporosis and other musculoskeletal conditions. In order to maintain healthy bones and muscles with age, supplement with the proper amount, eat fortified foods, and get a little sun exposure when you can. All of these efforts will support the musculoskeletal system!
