What is Vitamin D3?

Vitamin D3 is the common name for cholecalciferol.Vitamin D3 has two distinct uses. It can be taken as a supplement to improve our overall health or taken to treat osteoporosis. Many people with a vitamin d deficiency are told to include Vitamin D3 supplements in their diet.

Vitamin D3 also assists the kidneys to recycle phosphate back into the blood, helping the blood stay at the right pH.

Sunlight is a natural source of vitamin D3. People who stay inside most of the time (people in nursing homes or bedridden hospital patients) are most likely to be deficient of vitamin D3

Also, the darker your skin, the more sunlight you need to keep vitamin D3 at healthy levels. This is because the extra melanin found in darker skin slows the absorption of vitamin D3.

Best 10 Benefits of Vitamin D3

Vitamin D consists of five forms, including cholecalciferol, or vitamin D3. This fat-soluble nutrient and prohormone is naturally present in only few foods, though additional vitamin D can be obtained through sun exposure. Aversion to the sun can lead to a vitamin D deficiency; also, individuals with darker skin are more prone to this deficiency, as melanin slows the absorption of vitamin D3. This vitamin has many benefits, including treating osteoporosis and depression. Let’s examine these benefits in greater depth.

1. Boosts cognitive function

Research has shown that the brain has numerous vitamin D receptors. Without adequate D3, cognitive function can become impaired, leading to mood disorders, poor memory, anxiety, and depression.

2. Promotes bone health

Women deficient in vitamin D3 are significantly more prone to bone fractures and osteoporosis. This is because the vitamin aids in the absorption of calcium and phosphorus, two nutrients that maintain bone density.

3. Prevents diabetes

A deficiency in vitamin D3 impairs the secretion of insulin and glucose. This vitamin stimulates the pancreas, which is responsible for producing and secreting insulin. By consuming the proper amount of vitamin D3, diabetes becomes much more manageable.

4. Boosts immunity

Vitamin D3 puts cells in the immune system on high alert when pathogens enter the body. This vitamin activates these cells so they can kill toxins that would cause disease. Vitamin D3 also prevents several types of autoimmune disease.

5. Protects vision

Recent studies have shown that a healthy intake of vitamin D3 prevents vision loss and other eye disorders such as dry eye syndrome and age-related macular degeneration.

6. Boosts fertility

Struggling with fertility? You may have low levels of vitamin D3. Proper intake of this vitamin aids in the production of sex hormones. A deficiency can cause polycystic ovary syndrome, PMS, and even infertility.

7. Relieves migraines

Research has shown that men with low vitamin D3 levels face twice the risk of developing chronic migraines than men with adequate levels. This is thought to be due to the vitamins anti-inflammatory properties that reduce inflammation in the brain.

8. Fights breast cancer

Recent research suggests that many cases of breast cancer are caused at least in part by a deficiency of vitamin D3. This vitamin hinders the growth and spread of cancer cells, making it an incredibly valuable supplement for women.

9. Improves sleep

A low intake of vitamin D3 can increase the risk of sleep disorders, while a healthy intake regulates your circadian rhythm and prevents sleep apnea and insomnia.

10. Promotes cardiovascular health

Vitamin D3 supplements can prevent numerous cardiovascular diseases such as stroke, heart attack, hypertension, atherosclerosis, peripheral arterial disease, and many more. It is extremely effective in maintaining a healthy blood pressure and preventing heart enlargement.
