What is Vitamin D?


Vitamin D has been a hot topic in recent years due to its many benefits. If you don’t get enough vitamin D from the sun or foods, it may lead to increased risk of cancer and osteoporosis. To make up for this deficit, doctors recommend taking an extra supplement every day.

Vitamin D is a fat-soluble vitamin that plays an important role in human health. It helps to regulate calcium levels in the body, especially in adults, and it acts as an immune system booster. This is essential to promote bone health and strong teeth.

Vitamin D deficiency can lead to bone pain, muscle weakness, and weight loss. Its deficiencies have also been linked to some types of cancer, heart disease, muscle weakness, and arthritis.

Sources of vitamin D include food such as fish, dairy products, eggs, and fortified cereal or supplements. It can also be produced by our bodies when exposed to sunlight.

Some doctors recommend that people should take 1000IU per day but the recommended dosage depends on your age, skin type, and season. The recommended daily intake for adults is 600IU/day, around 3 cups of milk or 4 ounces of salmon (depending on the person).

The effects of too little or too much Vitamin D3 can be serious. Some sources of this vitamin include eggs, oily fish such as salmon, and vitamin supplements. It can come in the form of capsules or liquids which are sometimes taken orally and other times injected into the body.
