How does vitamin D3 work?
Vitamin D is a fat-soluble vitamin that can be found in only a few foods, added to others, and obtained as a dietary supplement. It’s also made naturally by the body when sunlight hit the skin and stimulate vitamin D synthesis.
Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol.
Calcitriol circulates as a hormone in the blood and regulates calcium and phosphate metabolism for bone formation and other physiological functions. Vitamin D sufficiency is achieved when serum 25(OH)D concentrations are ≥30 ng/mL (75 nmol/L).
Most vitamin D is derived from sun exposure; however, the amount of sun exposure required to maintain adequate levels varies by age, skin pigmentation, season, latitude, time of day, clothing habits, and use of sunscreen.
People who have limited sun exposure need to include good sources of vitamin D in their diet or take supplements to achieve and maintain adequate serum 25(OH)D concentrations.
How much vitamin D3 should a person take?
There is no Recommended Dietary Allowance (RDA) for vitamin D. The Institute of Medicine (IOM) recommends a daily intake of 600 IU (15 mcg) of vitamin D for most adults between the ages of 19 and 70 years, including pregnant and lactating women.
The IOM set an Upper Limit (UL) of 4000 IU (100 mcg) per day for adults to avoid the potential risk of adverse health effects associated with excessive vitamin D intake.
Pregnant and lactating women, as well as people over the age of 70 years, are advised to get more than 600 IU/day because they are at increased risk for vitamin D deficiency.
People with dark skin are at increased risk for vitamin D deficiency and may need higher intakes of vitamin D. Some researchers recommend that people with dark skin should get up to 1000-2000 IU (25-50 mcg) of vitamin D per day.
A number of factors can affect how much vitamin D you need, including your age, skin color, and level of sun exposure. Talk to your healthcare provider about how much vitamin D you should take.

Vitamin D’s most important functions include supporting the immune system and improving its function. It stimulates T-cell production and aids in the proper response to viral infections, such as the common cold, influenza, and other community-wide illnesses caused by viruses, bacteria, and fungus.
3. Might Prevent Certain Types of Cancer
Vitamin D3 can assist decrease the chance of developing particular types of cancer. Epidemiological studies have shown that people who reside in southern/equatorial regions and are more exposed to the sun have a lower risk of some malignancies.
Vitamin D has been linked to cancer in numerous studies. Vitamin D aids in the repair and regeneration of cells, which might slow the growth of cancerous tumors, stimulate the death of cells that have been damaged by cancer, and decrease blood vessel formation in tumors.
4. Improve Brain Function
Vitamin D has been linked to a variety of bodily processes, including the brain’s function. Vitamin D receptors may be found in all parts of the brain and spinal cord. Vitamin D helps you by promoting nerve growth and repair as well as stimulating and inhibiting neurotransmitter synthesis.
Vitamin D, it is thought, benefits the brain by lowering inflammation and preserving neurons. Vitamin D has also been shown to protect neurons in animal studies, which may help to explain why it promotes alertness and quick reaction time.
Another study looked at the relationship between Vitamin D levels and performance on mental tests in a group of people. This research revealed that those with lower Vitamin D levels did worse than those with sufficient amounts, suggesting it improves attention.
5. Boosts Your Mood
The diminished sunlight exposure in the winter, as well as the darker months, is advantageous for Vitamin D. A number of studies have shown that low levels of Vitamin D3, linked to insufficient sunshine exposure, are associated with Seasonal Affective Disorder (SAD) symptoms.

Vitamin D3 levels have been shown to decrease, which has been linked to lower levels of serotonin in the brain, a neurotransmitter that controls emotions. You may improve your mood by taking a Vitamin D3 supplement or increasing your sun exposure.

Vitamin D deficiency has been linked to rheumatoid arthritis – a chronic inflammatory disease of the joints. Rheumatoid arthritis is an autoimmune disorder.
The linings of the joints are mistaken by the immune system for foreign materials, resulting in inflammation and stiffness.
A lack of Vitamin D might lead to the development of rheumatoid arthritis since it is required for the immune system’s proper functioning. Raising your Vitamin D levels has the potential to alleviate the severity and incidence of this disease as well as other autoimmune disorders.

If you have diabetes in your family or have been diagnosed with pre-diabetes, you might want to consider taking more Vitamin D. Recent studies have shown a link between Vitamin D deficiency, insulin resistance, and type 2 diabetes. You may be able to prevent the development of type 2 diabetes by overcoming insulin resistance.
The cells in the pancreas that produce insulin have alpha-hydroxylase enzymes and VDRs, which are important in determining glucose tolerance and resistance to insulin.
Vitamin D deficiency can also reduce the secretion of insulin from the pancreas, which might cause insulin resistance and modify how the body responds to glucose. Given these findings, it is a good idea to consult with your doctor to see if taking extra Vitamin D improves your overall health.
9. Lowers Blood Pressure
Low Vitamin D levels have been linked to high blood pressure in several long-term studies.
It was previously unknown whether Vitamin D insufficiency causes hypertension, but a large genotypic research with over 150,000 participants has revealed that low levels of Vitamin D can induce high blood pressure.
Those who had the most vitamin D in this research had lower blood pressure. It was revealed that an increase of 10% in Vitamin D levels resulted in a 10% reduction in high blood pressure. An increase in your Vitamin D levels may help if you have high blood pressure or wish to prevent it from developing.
10. Reduces Risk of Heart Disease
Vitamin D deficiency has been linked to a variety of health problems, including high blood pressure, heart disease, congestive heart failure, peripheral arterial disease, strokes, and heart attack. Vitamin D levels can be elevated to help reduce the chance of developing heart illness and its symptoms.
Furthermore, because it may aid in weight reduction and maintaining healthy body weight, this vitamin might also be able to minimize the negative effects of obesity and excessive body fat on heart disease. To discover more about Vitamin D advantages, consult with your doctor.
11. Vitamin D can fight inflammation
Vitamin D is beneficial to the immune system because it helps regulate the production of cytokines. Cytokines are proteins that are used by the immune system to communicate with other cells, and when they are produced in the wrong amounts or at the wrong time, they can cause inflammation.
Vitamin D can also help reduce the risk of infections by promoting the production of white blood cells and increasing the efficiency of T-cells. A lack of Vitamin D has been linked to an increased susceptibility to infection, so maintaining healthy levels might help keep you from getting sick.
12. Vitamin D can help Strengthen Oral Health
Vitamin D helps our bodies absorb calcium, which is essential for dental health. Vitamin D has been shown to be beneficial for oral health, according to a 2011 analysis published in The Journal of the Tennessee Dental Association.

Vitamin D is essential for strong bones. It helps the body absorb calcium, which is necessary for bone health. A lack of vitamin D can lead to a condition called osteoporosis, which weakens bones and makes them more susceptible to fractures.
14. Supports Proper Lung Function
Vitamin D is essential for proper lung function. It helps the body absorb calcium, which is necessary for healthy lungs. A lack of vitamin D has been linked to a variety of respiratory problems, including asthma and COPD.
15. Supports a Healthy Nervous System
Vitamin D is essential for a healthy nervous system. It helps the body absorb calcium, which is necessary for healthy nerves. A lack of vitamin D has been linked to a variety of neurological problems, including Alzheimer’s disease and dementia.
16. Encourages Healthy Hair Growth
Vitamin D is essential for healthy hair growth. It helps the body absorb calcium, which is necessary for healthy hair follicles. A lack of vitamin D has been linked to a variety of hair problems, including hair loss and alopecia.
17. Improves Cognitive Function and Prevents dementia
Vitamin D is essential for brain development, and a lack of it has been linked to cognitive problems and dementia. A 2017 study published in the journal Neurology found that people with vitamin D deficiency were more likely to experience a decline in cognitive function over a six-year period than those who had sufficient levels of the vitamin.
Should everyone be taking vitamin D3?
There are many benefits of vitamin D, and it’s often called the “sunshine vitamin” because we can produce it when our skin is exposed to sunlight. Vitamin D is important for strong bones and teeth, and it helps our bodies absorb calcium.
It also supports our immune system and may help prevent certain chronic diseases such as cancer.
