Low Energy and Bone Pain? Your Vitamin D Levels Might Be Dropping

Feeling tired all the time or having ongoing bone pain can be frustrating or even hard to accept. One of the most often overlooked contributors to your ongoing fatigue or unexplained bone pain is having a vitamin D deficiency. Vitamin D is essential for your body to have adequate energy and strong bones. The following will outline how low vitamin D can affect you, how you can become vitamin D deficient, and what you can do about it.

What Is Vitamin D and Why Is It Important?

Vitamin D is a fat-soluble vitamin but also acts as a hormone within your body. It is required for hundreds of functions in your body, but it is especially important for your body to absorb calcium and phosphorus, two essential minerals for healthy bones. If your body lacks vitamin D, you may have weak, brittle, or painful bones.

In addition, vitamin D is important for your immune function, muscle function, and even your mood. There is plenty of evidence to suggest that low vitamin D levels contribute to fatigue and contribute to being weak regardless of how much (or little) activity you engage in every day. Having ongoing fatigue or weakness can make daily tasks much harder and leave you feeling tired or depleted.

Signs That Your Vitamin D Might Be Low

If you notice low energy levels and aching in your bones, your vitamin D levels may be dipping. Here are a few more signs to look out for:

  • Muscle aches/cramps
  • Bone tenderness or pain, especially in the lower back, hips, pelvis, or legs
  • Weakness such that it is difficult to get up or climb stairs
  • An increase in mood symptoms such as feeling sad or depressed.
  • Poor wound healing after injury.

Sometimes the symptoms are so mild or are dismissed as a way of getting old or simply being out of shape. Therefore, it is best to speak to a health care provider, especially if you notice certain complaints or issues persistently cropping up.

Why Are Vitamin D Levels Dropping?

Many people are not getting enough vitamin D for a variety of reasons:

1. Limited Sunlight Exposure We call vitamin D the “sunshine vitamin” because your skin is able to make it when you are exposed to sunlight. If you are inside most of the time, if you live in a cloudy climate or a northern climate, or you use a lot of sunscreen, you may be letting this source disappear.

2. Dietary Deficiencies The food supply has very few foods that naturally contain vitamin D. There are fatty fish like salmon, and there are some fortified foods like milk or some breakfast cereals that are fortified, but many people are not eating enough of these foods to get vitamin D on a regular basis.

3. Age and Health Conditions As we age, our skin produces less vitamin D. Some medical conditions, such as kidney or liver conditions, can also impact how your body utilizes and processes vitamin D.

4. Darker Skin Higher levels of melanin reduce the skin's ability to convert sunlight to vitamin D, so individuals with darker skin may be at higher risk for deficiency.

Why Bone Pain and Low Energy Are Connected to Vitamin D

Vitamin D assists your intestines in calcium absorption. Without adequate vitamin D, you may not be able to achieve proper calcium levels, resulting in bone loss or a deficiency of bone density called osteomalacia (softening of the bones which created aching and tenderness).

Additionally, vitamin D deficiency can impact muscle function, which may contribute to pain and fatigue. Your muscles may not feel like they are weak or fatigued but they are if there is inadequate vitamin D.

How to Check Your Vitamin D Levels

The best way to know if you have low vitamin D is a blood test ordered by a medical doctor. The form they frequently check is called 25-hydroxyvitamin D. The levels are commonly measured in nanograms per milliliter (ng/mL):

  • Deficiency: less than 20 ng/mL
  • Insufficiency: 20-30ng/mL
  • Adequate: 30-60ng/mL

If your vitamin D levels are low, your healthcare provider may recommend supplements or lifestyle changes.

Easy Ways to Boost Your Vitamin D

If you suspect you're short on vitamin D or you know you are, here's a few simple suggestions that may help:

  • Spend 10-30 minutes a day outside a few times a week with your arms and legs exposed and avoiding burning (the time will vary based on skin type and geographic location)
  • Eat some more vitamin D-rich foods like fatty fish (salmon, mackerel), egg yolks, fortified dairy or fortified plant milks and cereals
  • Take a vitamin D supplement, with permission of your doctor
  • Eat a balanced diet, with foods rich in calcium, to support healthy bones.

That's the key here, to live in moderation. Too much vitamin D from supplements can also create problems.

When to See a Doctor

Vitamin D supplement, but have no improvement with your tiredness and/or bone pain, or you have worsening symptoms, you should consult your healthcare provider. Sometimes there are other conditions that may affect your ability to perform daily activities, and a healthcare provider is able to help you find the appropriate diagnosis and treatment if necessary.
