Low Vitamin D? How it Affects Older Adults & What You Can Do

Posted by Kendal at Home on January 17, 2019 at 7:30 AM

When older adults don’t get enough vitamin D and calcium, bones can thin and weaken, which means they can fracture or break more easily. Vitamin D also helps to keep muscles strong; when yours aren’t as strong anymore, you’re more vulnerable to falls.

Fortunately, you can get vitamin D in multiple ways, including through:

  • Sun exposurevitamin d
  • Eating fatty fish
  • Eating fortified foods
  • Vitamin D supplements

Sometimes, people refer to this vitamin as the “sunshine vitamin” because your skin can make vitamin D with sun exposure. But, your skin’s ability to create this vitamin declines with age, and this strategy also comes with an increased risk of skin cancer.

You can get vitamin D by eating salmon, swordfish and mackerel, for example, plus milk, juice, yogurt, cereal and more that’s been fortified. As far as a vitamin D supplement, an expert quoted in BetterHealthWhileAging.net recommends a supplement of 1000 IU/day for most older adults.

Reasons why she typically makes this recommendation include the following:

  • The American Geriatrics Society suggests that medical professionals tell their older adult patients to take this amount to help prevent fractures.
  • Because older adults often spend limited time outdoors, they are at risk for deficiency.
  • For the majority of older adults, taking this vitamin D supplement presents little opportunity for harm.
  • Research shows that this amount of supplementation will typically prevent low vitamin D levels.

Another reason why it’s important to avoid deficiencies? Low levels of vitamin D have been connected to “slower information processing” in men who are middle aged and up. This includes “cognitive decline, mood disorders, and altered brain development and function resulting in neurodegenerative diseases and other medical disorders.”

Meanwhile, ScienceDaily.com reports on a December 2018 study that found how, in older adults, “Vitamin D deficiency was associated with a 75% increase in the risk of developing depression by 4 years.”

These findings held true even when controlling for multiple factors and, when excluding people from the study who took anti-depressant medications and vitamin D supplements, findings didn’t change.

Vitamin D Tips for Winter Time

Because this vitamin can be created through sun exposure, deficiencies can be more common in winter – and an article in Health.USNews.com offers tips to maintain vitamin D levels during the darker months.

First, focus on eating the right foods. You might be surprised by how much of this vitamin you can get when you eat strategically. A single serving of canned tuna, the article reveals, provides about one-third of what you need for an entire day. And, during a week’s time, you can eat seven eggs enriched with this vitamin as protection against deficiencies.

When the weather is “slightly warmer,” take a walk. You’ll need to have some skin exposed for this strategy to work, so it wouldn’t be effective or recommended on bitterly cold winter days.

Here’s one more idea. Consider a vitamin D lamp. Most light therapy boxes designed to help with seasonal affective disorder don’t increase levels of this vitamin, but there is one specific type of lamp that’s approved by the Food and Drug Administration for boosted vitamin D: the Sperti. Note that it costs $425, which isn’t cheap, but it is “cheaper than a cross-continental vacation and can be used every day.”

Supplementation: Dissenting Points of View

Not all experts believe that vitamin D supplements are a good idea. Here is information about relevant research and dissenting opinions, including how a 2018 report by the Journal of the American Medical Association showed unimpressive results in preventing falls.
