All About Vitamin D3

Vitamin D is so important for your overall health. Most people think that vitamin D is a vitamin, but in reality, the active form of vitamin D is one of the most potent hormones in your body, and regulates more genes and bodily functions than any other hormone yet discovered. Here are 3 important roles that Vitamin D does in our body.

Vitamin D and the Immune System

The immune system consists of an intricate network of antibodies and white blood cells to defeat new and previous invaders including viruses, bacteria, and drugs. Scientific research over the past three decades solidifies the connection between vitamin D and immune responses.

Vitamin D plays a critical role in your immune response and enables your body to produce 200+ antimicrobial peptides, which are necessary for fighting off a huge variety of infections. Adults who have low vitamin D levels are more likely to report having had a recent cough, cold, or upper respiratory tract infection.

So, our immune cell have something called Vitamin D receptors and with adequate amount of Vitamin D in the body it will provide protection. These receptors act as “gate keepers” by signaling and sorting out which external substances, can enter a cell. The receptors must be full with D3 to effectively regulate immunity and attack foreign invaders.

Vitamin D and Your Thyroid

Your thyroid gland is located in the front of your neck. It plays a vital role in a number of functions, including regulation of metabolism and calcium balance. Your thyroid gland produces thyroid hormone from iodine, including T4 and T3. Production and release of thyroid hormone is controlled by another hormone called thyroid stimulating hormone, or TSH. TSH is released into the blood from the pituitary gland and serves as a clinical indicator of thyroid function.

Scientists have known about the relationship between vitamin D and the thyroid for decades. The one thing researchers know for sure is thyroid function isn’t optimal and may not even work if you do not have adequate vitamin D.

For example, Researchers know that: Receptors for vitamin D are found within the thyroid gland.

These discoveries led scientists to explore how vitamin D fits into the overall picture of thyroid health. They found that low levels of vitamin D are linked to Graves’ disease, Hashimoto’s thyroiditis, and thyroid cancer

This doesn’t necessarily conclude that thyroid disease is caused by vitamin D deficiency however, it does suggest that vitamin D plays an important role.

There is a crucial final metabolic step that takes place inside your cells where thyroid hormone actually works. Vitamin D needs to be present at sufficient levels in the cell in order for the thyroid hormone to actually affect that cell or, if your on medication, for thyroid med’s to work properly.

Vitamin D and Bone Health

We have all heard how vitamin D is great for your bones. But did you ever understand why? we are here to tell you. The major biological function of Vitamin D is to keep the serum calcium and phosphorus concentrations within a normal range. This helps to maintain essential cellular functions and to promote mineralization of the skeleton.

The active form of vitamin D also, stimulates the absorption of calcium from your gut and mobilizes calcium in your bones. There is a pretty awesome relationship between Calcium and Vitamin D one of the benefits to having this relationship is Vitamin D will help your kidneys to reabsorb calcium this helping with the prevention of Kidney stones. It is also needed for bone growth and bone remodeling without sufficient vitamin D, bones can become thin, brittle, or misshapen.

 Words For The Wise

If you are curious about what your Vitamin D levels are we suggest to ask your doctor to have them test it. Don’t just self supplement because Vitamin D also has down sides when too much is ingested. Always consult with a nutrient professional and  your doctor to make sure you do not cause more harm to yourself.
