Vitamin D Test: Here’s Why Vitamin D is So Crucial for Your Wellbeing

The human body needs certain vitamins and minerals in order to function properly and stay healthy. These nutrients play a number of important roles, such as boosting immunity, maintaining bone health, and supporting the overall growth of a person. Vitamin D is one of the most essential nutrients that an individual requires for several bodily functions. It helps the body absorb calcium, helping make the bones and teeth stronger. Other than this, vitamin D also helps in keeping the muscles, nerves, and immune system functioning properly.

Importance of Vitamin D

It is important for everyone to have adequate levels of vitamin D in their body. The nutrient’s main task is enabling the body to absorb calcium and supporting bone growth and remodeling. Vitamin D offers benefits like:

  • Strengthening the muscles and bones in the body.
  • Supporting the immune system and fighting inflammation.
  • Supporting oral health.
  • Helping prevent type 1 and type 2 diabetes.
  • Helping in the treatment of hypertension.
  • Supports weight loss.
  • May help battle depression.
  • Reduced risk of multiple sclerosis.
  • Lower chances of heart disease.

There are three ways in which the body gets vitamin D. One is through consuming foods that are rich sources of vitamin D, like dairy products, fatty fish, egg yolks, etc. and another is through vitamin D supplements. The body also produces vitamin D when the bare skin is exposed to sunlight. There are two forms of vitamin D found in the human body – vitamin D2, which comes from plant-based sources and fortified food, and vitamin D3, which is produced in the body and also comes from animal-sourced foods. For both men and women, the benefits of vitamin D3 include:

  • Boosted immunity.
  • Weight management support.
  • Mood regulation.

Vitamin D Deficiency

There are several factors that can affect an individual’s ability to get adequate amounts of vitamin D, leading to a vitamin D deficiency. These may include less exposure to sunlight, high levels of melanin in the skin, regular use of sunscreen, high levels of pollution, or having an unhealthy diet. The deficiency of this nutrient can lead to several symptoms, like fatigue, aches, pains, severe weakness of the muscles and bones, stress fractures, etc.

High Levels of Vitamin D

Excessive consumption of dietary supplements can lead to high levels of vitamin D in the body. This is unlikely to happen through diet or sun exposure, as that form of the vitamin is regulated by the body. Vitamin D toxicity also impacts blood calcium levels and can result in a number of issues like nausea, vomiting, apathy, pain in the abdomen, confusion, dehydration, etc.

The Vitamin D Blood Test

A vitamin D test is a simple blood test used to keep a check on vitamin D levels in the body. As there are two forms of this nutrient – vitamin D2 and vitamin D3, the test detects concentrations of 25-hydroxyvitamin D, which is a by-product formed in the body due to vitamin D assimilation.

The test can help determine if an individual’s vitamin D levels are too high or too low, so the same can be remedied in time with proper treatment and lifestyle changes.

Warning Signs of Vitamin D Deficiency

There are some signs and symptoms that may indicate a vitamin D deficiency. If an individual experiences any of these signs, their doctor may suggest undergoing a vitamin D and B12 test. Symptoms to look out for include:

  • Joint pain
  • Muscle weakness
  • Frequent body aches
  • Soft bones
  • Certain bone deformities
  • Bone weakness, leading to frequent fractures.
  • Low bone density (osteoporosis or osteopenia)

Risk Factors

Not consuming a nutritious diet and not spending enough time in the sun may lead to a vitamin D deficiency. However, there are also certain factors that put one at a higher risk for developing the deficiency, such as:

Other than this, it is also very common for a pregnant female to experience low vitamin D symptoms. This is mostly because pregnancy is a time during which a woman’s body goes through a number of changes, which may lead to several deficiencies, including that of vitamin D.

The price of the vitamin D test is well worth the cost, given the numerous health issues that abnormal levels of the nutrient can lead to.
