Vitamin D, also known as “the sunshine vitamin,” is a necessary nutrient for the body. It aids in the regulation of phosphorus and calcium absorption. Furthermore, it is important in preventing inflammation in the body. However, vitamin D can be thought of as a hormone rather than a vitamin.
It is due to our bodies’ ability to produce vitamin D from cholesterol. This process, however, necessitates a daily dose of sunlight. As a result, spending some time in the sun every day can help us meet our daily vitamin D requirements. However, vitamin D deficiency is a major public health concern worldwide, and many people choose to take vitamin D supplements.
It is so common that a large portion of the population requires vitamin D supplements to meet their daily requirements. According to research, over one million people worldwide have low vitamin D levels, and half of the population suffers from vitamin D deficiency. Vitamin D is found in extremely low concentrations in our foods. As a result, it is insufficient to meet our daily needs. As a result, most people require vitamin D supplements to meet their needs.
Vitamin D keeps the body healthy by maintaining and restoring its nutritional levels. People who do not get enough sun exposure, on the other hand, need vitamin D supplements. So, if you’re wondering whether you should take vitamin D supplements, this article will help you get some (better) clarity.
What exactly is Vitamin D?
Vitamin D is a lipid-soluble nutrient. As a result, the body requires an adequate amount of healthy fats to absorb this vitamin. It is required by our bodies to maintain bone health and to absorb calcium and phosphorus from the small intestine.
According to research, people who are deficient in vitamin D can develop brittle, soft, and weak bones. Furthermore, a lack of this vitamin may contribute to the development of rickets in children and osteomalacia in adults.
Vitamin D Varieties
Vitamin D comes in five different forms: D1, D2, D3, D4, and D5. However, the most important forms of vitamin D for the human body are D2 and D3.
Vitamin D2 (Ergocalciferol)
Vitamin D2 is derived from plant-based foods that receive adequate sunlight, such as mushrooms. These foods are the best sources of vitamin D for vegetarians.
Vitamin D3 (Cholecalciferol)
Vitamin D3 is found in foods such as fish. In the presence of sunlight, our skin also produces vitamin D3 from cholesterol in our bodies.
Both vitamins are necessary for the proper functioning of our body. Supplements of both types of Vitamin D, namely Vitamin D2 and Vitamin D3, are available without a prescription and can be purchased over-the-counter.
According to a meta-analysis, vitamin D3 is the best choice for vitamin D supplements. In comparison, it is a more easily absorbed form. Vegetarians, on the other hand, prefer vitamin D2 to vitamin D3.
Requirements for Vitamin D
International Units (IU) or micrograms are the standard units of measurement for vitamin D intake (mcg). 1mcg is equal to 40 IU of vitamin D. Every day, our bodies require vitamin D. According to research, the average vitamin D requirements are:
- Infants: 10 mcg or 400 IU from birth to 12 months
- Children and teenagers aged 1 to 18 years: 15 mcg or 600 IU
- Adults aged 19 to 70 years: 15 mcg or 600 IU
- Adults over the age of 71: 20 mcg or 800 IU
- Women who are pregnant or breastfeeding: 15 mcg or 600 IU
Functions of Vitamin D
When the cholesterol in our bodies converts to vitamin D, it aids in a variety of functions:
- Vitamin D helps to prevent mood disorders like mood swings and depression.
- By regulating calcium and phosphorus levels in our bodies, it reduces the risk of bone fractures and deformations.
- Vitamin D regulates the body’s blood sugar levels.
- It also keeps cholesterol levels in check.
- It controls muscle and nerve function.
Vitamin D Supplements
Vitamin D is primarily obtained from three sources: your skin, your diet, and vitamin D supplements. Supplements are necessary because most of us do not get enough vitamin D from natural sources.
The use of these supplements on a daily basis is more effective than administration on a monthly or weekly basis. These supplements are a dependable and effective way to ensure our bodies’ proper functioning by meeting their vitamin D requirements.
Signs You Might Need Vitamin D Supplements
When you are diagnosed with vitamin D deficiency, you may require vitamin D supplements. However, before taking any supplements, you should consult a doctor and have your blood sugar levels tested. It may be required if you frequently experience the following symptoms:
- Feeling drowsy or tired?

- Hair thinning
- Mood imbalances
Vitamin D Supplements’ Advantages and Applications
Vitamin D supplements are necessary for our bodies to function properly. They contribute to the proper functioning of cells, nerves, and muscles. The following are the uses and benefits of vitamin D supplements:
Bones and muscles are strengthened.

Aids in the development of infants
According to one study, vitamin D helps babies develop strong teeth and bones. Vitamin D supplements can also help prevent rickets in children.
Encourages Mental Health
According to research, low vitamin D levels in our bodies can lead to a variety of mood disorders and depression. As a result, maintaining an optimal vitamin D level through vitamin D supplements can improve mental health and mood regulation.
Vitamin D receptors are found on the surface of our white blood cells. According to one study, it boosts immunity by combating harmful viruses and bacteria. As a result, vitamin D supplements are known to boost an individual’s immunity.
Reduces the Risk of Diabetes
According to research, vitamin D aids in the regulation of insulin levels. Diabetes can be caused by high insulin levels in the body. In addition, vitamin D supplements help to keep the body’s glucose levels in check. As a result, they contribute to a lower risk of diabetes.
These are some precautions to take when taking Vitamin D supplements:

- Vitamin D supplements should be taken with food rather than on an empty stomach.
- If a person is over the age of 50 or has osteoporosis, their daily vitamin D supplement dosage should be between 800 IU and 1000 IU.
Possible Adverse Reactions
When taken in the recommended amounts, vitamin D supplements are generally safe to consume. However, if taken in higher doses for a longer period of time, these supplements may cause side effects due to vitamin D toxicity.
Hypercalcemia is a condition caused by an excess of calcium in the blood. It is caused by an excess of vitamin D consumption.
Vitamin D aids in calcium absorption from the body. However, if your calcium levels exceed a certain level, you may develop hypercalcemia. The cutoff point is 0.104 mg/mL, or 10.4 mg of calcium per deciliter of blood.
High calcium levels in the body can also cause appetite loss, muscle weakness, reduced reflexes, and muscle and joint pain. It can also cause confusion, disorientation, difficulty thinking, irritability, anxiety, and other problems.
Calcium in the blood can combine with phosphate to form crystals that accumulate in the tissues. These tissues have the potential to harm the organs.
Excessive vitamin D intake, for example, can result in calcium deposits in the kidney. Nephrocalcinosis can occur when calcium deposits build up in the tissues of the kidney. It is a condition that can result in kidney failure.
Excess vitamin D can cause extreme hypercalcemia, which can impair the proper functioning of the cells in the heart. As a result, it causes irregular heartbeats, which can lead to a blockage and a heart attack.
Vitamin D deficiency can result in calcium and phosphate deposition in the tissues. These calcium and phosphate deposits can impair lung function. It can cause chest pain, difficulty breathing, and persistent coughing. As a result, a high dose of vitamin D supplements can cause significant lung damage.
Influence on Mental Health
A person’s mental status can be affected by hypercalcemia. Excess vitamin D consumption is the primary cause of hypercalcemia. As a result, a high intake of vitamin D supplements can cause severe mood changes and depression.
Pain and Brittle Bones
When there is an excess of calcium in the body, the minerals in the bones do not effectively bind with the hormones present. As a result, it can cause achy bones, severe joint pain, and a hunched posture. The best way to avoid side effects is to limit your intake of vitamin D supplements.
The Sun: A Natural Source of Vitamin D
Vitamin D is known as the “sunshine vitamin” for a reason. When exposed to sunlight, your skin can produce vitamin D with the help of your body’s cholesterol.
The best times to get sunlight are in the morning between 9:30 a.m. and 10:30 a.m., and in the evening between 4:30 p.m. and 6:30 p.m., when the sun is at its highest point. As a result, the body can efficiently synthesise vitamin D during the midday period.
Melanin is the pigment that gives your skin its colour. Melanin levels are higher in dark-skinned people than in light-skinned people. Vitamin D production is also influenced by the colour of your skin. Dark skin, for example, produces less vitamin D than light skin.
This is due to excess melanin in dark skin, which prevents vitamin D absorption from sunlight. As a result, dark-skinned people must spend more time in the sun than light-skinned people to get the same amount of vitamin D.
People with dark skin and those who live in cold climates do not get enough sun exposure. As a result, they rely on vitamin D foods and supplements to meet their vitamin D requirements.
Vitamin D-Rich Foods
Prolonged sun exposure can cause sunburns and raise the risk of skin cancer. As a result, you cannot meet your needs solely through sunlight. Although food only accounts for 10% of the total vitamin D present in our bodies, we can obtain some vitamin D from it. The rest can be obtained through sunlight and supplements.
Vitamin D can be found in both vegetarian and non-vegetarian foods.

Salmon contains a lot of vitamin D. It also contains high-quality lean protein and is high in omega-3 fatty acids. Cooked salmon contains 447 IU of vitamin D.
Vitamin D, also known as “the sunshine vitamin,” is a nutrient that the body requires. However, because we do not get enough vitamin D from natural sources, taking vitamin D supplements can meet our needs. These supplements aid in the maintenance of optimal vitamin D levels as well as the regulation of calcium and phosphorus in the small intestine.
Excess vitamin D in our bodies, on the other hand, is harmful and can cause hypercalcemia, which can lead to kidney and lung damage. It may also have an effect on your mental health. As a result, if you decide to take supplements, consult a physician first to determine which supplement is best for your body.
With the fats in our bodies, vitamin D is easier to absorb. As a result, it is preferable to take vitamin D supplements after the largest meal of the day. It doesn’t matter if it’s for breakfast, lunch, or dinner. Vitamin D supplements are available in a variety of forms, including liquids, capsules, gummies, and chewable tablets.
