What are the Dangers of Insufficient Vitamin D Levels?

Canadians are disproportionately affected by a lack of vitamin D due to the dark winter months when the UV index is too low to provide any benefits. This puts Canadians at higher risk of certain illnesses and diseases that adequate vitamin D levels would prevent. Vitamin D has long been recognized as an important factor in preventing rickets in children, but recent research has shown many other diseases it helps to defend against. Below are some of the medical issues that vitamin D deficiency contributes to and how you can help prevent them.

What Vitamin D Is And What It Does

Vitamin D helps your body absorb calcium, magnesium, and phosphate. Vitamin D also helps the body to prevent abnormal cells from multiplying in the breasts and colon, helps regulate blood pressure in the kidney, and helps regulate blood sugar levels in the pancreas. There are ways to obtain vitamin D other than through exposure to sunlight, such as by taking supplements or by eating certain vitamin D rich foods like fish oils, egg yolks, and fortified dairy products. Getting enough vitamin D can be particularly difficult for those who are over the age of 70, as the skin does not produce as much vitamin D and that age group tends to spend less time outdoors in the sunlight. Vitamin D is also essential for the growth and health of children.

Illnesses Are Associated With Vitamin D Deficiencies

  • Seasonal Affective Disorder. Seasonal Affective Disorder (SAD) is a type of depression that typically occurs during the fall and winter season. It can make you feel moody, fatigued, disinterested in activities you usually enjoy, or hopeless. Vitamin D and serotonin deficiencies along with a change in your circadian rhythm can lead to higher rates of SAD.
  • Increased Cardiovascular Disease. This encompases many different heart maladies, including coronary heart disease, congestive heart failure, heart attacks, and more. A lack of vitamin D contributes to heart complications.
  • Diabetes. Because vitamin D helps to regulate blood sugar levels within the pancreas, people suffering from type 2 diabetes are likely to benefit from increased vitamin D levels.
  • Osteoporosis. Vitamin D is essential to bone health, as it helps the body absorb calcium. A lack of vitamin D can cause the bones to weaken and be more prone to breaking.
  • Compromised Immune System. A lack of vitamin D can contribute to an overall weakening of the immune system, which makes you more susceptible to colds and flu. This is particularly concerning during the COVID-19 pandemic, as a strong immune system can help fight off the virus as well as fight off other viruses that may leave a person susceptible to COVID-19.

Treatment For Vitamin D.

For Canadians, where getting more sunlight isn’t an option, there are two main ways to get more vitamin D: eat vitamin D rich foods and take supplements. The amount of vitamin D you will need will depend on your age, health conditions, and current vitamin D levels. Vitamin D2 and D3 testing is now available through Ichor Blood Services in partnership with the renowned Mayo Clinic Laboratories for analysis.

Q: What happens when children don’t get enough vitamin D?
A: Children need vitamin D to facilitate bone growth, strengthen muscles, and help develop motor function. Children also need enough vitamin D to help prevent aches and pains, fractures, and rickets, as well  as heart disease, osteoporosis, and some cancers later in life. Children can also suffer from Seasonal Affective Disorder, although it is more common in older teenagers.
