Is a Low Vitamin D Level Affecting Your Thyroid?

Vitamin D deficiency is when your vitamin D level is too low. Unfortunately, it is very common and affects over a billion people worldwide. Yet, vitamin D levels are not commonly checked. Why is this the case? One barrier, is that most health insurance companies will not cover the cost to check a vitamin D level.
Why is Vitamin D so important?
Vitamin D has many important roles in helping your body function properly!
Vitamin D plays a significant role in several of your immune functions:
- Vitamin D plays a role in numerous effects on your cells within the immune system including lessening the production of inflammation within the body.
- Studies show that vitamin D plays a significant role in reducing the likelihood of autoimmune disease such as Hashimoto’s and Grave’s disease (auto immune thyroid disease) likely due to decreasing the production of inflammation.
Vitamin D is also beneficial for:
- Bone and muscle development
- Calcium absorption
- Boost mood and energy levels
What are some symptoms individuals experience with a Low Vitamin D level?
- Tired or sluggish
- Bone pain
- Muscle weakness, aches or cramps
- Decreased mood or depression
- Symptoms of a Low Thyroid: feeling sluggish, having brain fog, hair loss, trouble losing weight, decreased mood and constipation to name a few.
What exactly is Vitamin D?
It is a fat-soluble vitamin that can be produced endogenously when UV rays from the sunlight strike the skin and can trigger vitamin D synthesis. There are also a few foods that contain some vitamin D such as cod liver oil, trout, salmon and mushrooms. Vitamin D has to be converted to an active form for our bodies to recognize and use it. First, your liver converts the vitamin D to 25-hydroxyvitamin D and then your kidneys change this form of vitamin D to 1,25-dihydroxyvitamin D so that your body can recognize and use it.
How do you know if you are low in Vitamin D?
A blood test can determine if your body is low in vitamin D. Per The National Institute of Health, the best indicator of vitamin D status is to obtain a blood test called a 25-hydroxy vitamin D level. Other labs that may also be helpful are calcium, ionized calcium and parathyroid hormone levels depending on an individual’s health journey.
Every organization has a different idea of the number that defines vitamin D deficiency when interpreting lab results.
From a functional medicine perspective, the goal is to have an optimal level of vitamin D. For most people, the goal is to have a vitamin D level between 50-80 ng/mL.
If you are living at high altitudes in a place that is colder in the winter, your vitamin D level is likely going to be lower in the winter months due to having less sun exposure.
Most people need to supplement with vitamin D. How do you know how much to supplement? First, you need to determine your level with a blood test. You may need less vitamin D supplementation in the summer and more in the winter—depending on where you live.
As with anything, balance is key. Being low in vitamin D is not good, but also having too high of a vitamin D level is not good either. When vitamin D levels are too high, it can cause toxicity! Remember, vitamin D can be stored in the body! If vitamin D levels are too high it can cause many problems. These problems include: weight loss, weakness, poor appetite, nausea, vomiting, not feeling hungry, rhythm issues with the heart that can lead to heart disease. For this reason, it is important to evaluate your vitamin D levels regularly!
If you are concerned about your vitamin D levels, have known thyroid issues or have symptoms of a low thyroid, don’t forget about having your vitamin D level checked.
