Vitamin D Deficiency: Symptoms and Solutions by Donna Hayek, RD

Did you know that most Americans are deficient in Vitamin D, even those who get regular sunlight exposure? Vitamin D deficiency is surprisingly common and it can quietly impact many areas of your health.

Why Vitamin D Matters

Vitamin D plays a vital role in supporting brain health, reducing inflammation, boosting immunity, and regulating muscle and bone health. It also works in conjunction with Vitamin K to help the body absorb calcium, which is essential for maintaining strong bones, especially as we age.

Vitamin D is a fat-soluble, essential vitamin. Taking a supplement can be helpful, particularly if your diet is low in Vitamin D-rich foods. A typical maintenance dose ranges from 1,000 to 2,000 IU daily. It’s also a good idea to have your Vitamin D levels checked annually with bloodwork.

How to Check and Correct Your Vitamin D Levels

If your levels are very low, your doctor may recommend a higher dose – such as 50,000 IU weekly for a short period – to quickly bring your levels back to normal. The standard blood level range is 30–60 nmol/L.

When consuming Vitamin D through food or supplements, it’s important to pair it with a meal that includes healthy fats or magnesium-rich foods. This improves absorption and helps your body use Vitamin D more effectively.

Best Foods to Boost Vitamin D Absorption

Sources of Healthy Fats and Magnesium to Pair with Vitamin D:

  • Avocados
  • Olive oil
  • Almonds
  • Peanuts & peanut butter
  • Seeds (like sunflower seeds)
  • Salmon
  • Milk
  • Yogurt
  • Egg yolks
  • Spinach
  • Tofu
  • Keifer
Take Charge of Your Health

Be proactive with your health. Get your Vitamin D levels checked regularly, and ensure you’re getting enough through diet, supplementation, or lifestyle adjustments.
