Normal Vitamin D Levels

normal vitamin d levels

Understanding normal vitamin D levels is essential for maintaining good health.

A normal range for vitamin D in the bloodstream is generally considered to be between 20 to 50 nanograms per millilitre (ng/mL). 

If your vitamin D concentrations are within this range, it means that your body likely has enough vitamin D for proper functioning to promote bone robustness, immune system regulation, and mood stabilisation.

In this article, we at Vitamart will explore what constitutes balanced vitamin D quantities by evaluating who should be screened for a potential deficiency and the overall effects of vitamin D on your wellness.

What this article covers:

What Are Normal Vitamin D Levels?

Most healthcare professionals consider levels between 20 to 50 ng/mL to be normal and sufficient for your overall welfare.

Vitamin D volumes are typically measured through a blood test that checks for 25-hydroxyvitamin D, which is the main form of vitamin D in the bloodstream.

How Much Vitamin D Do I Need?

The recommended dietary allowance (RDA) for vitamin D amounts to 600-800 IU for most adults, with higher quantities for older individuals or those at risk of deficiency.

Based on our observations, some people may require higher RDA doses (potentially 2,000-4,000 IU per day or more) to maintain optimal amounts. This is especially critical during winter months or if they have limited sun exposure.

What Happens If I Don't Get Enough Vitamin D?

Being low in vitamin D (often called a vitamin D deficiency) can lead to various medical issues, including:

  • fatigue
  • bone pain
  • muscle weakness
  • an increased possibility of fractures

In severe cases, it can lead to a condition called osteomalacia in adults where bones become soft and weak, or rickets in children, where the bones become distorted and bow-legged.

Insufficient vitamin D levels have also been linked to an increased likelihood of certain cancers, autoimmune diseases, and mood disorders.

Canadians with vitamin D deficiency tend to fall into a range of 21-29 ng/mL, which isn't optimal for physical and mental well-being.

How Do You Increase Your Vitamin D Levels?

There are several ways to boost your vitamin D levels:

  • Sunlight Exposure: Spend 10-30 minutes in the sun a few times a week to naturally boost your vitamin D intake.
  • Diet: Consume foods rich in vitamin D, such as fatty fish (salmon, mackerel and sardines), egg yolks, fortified dairy products, and mushrooms exposed to UV light to lead a healthier lifestyle.
  • Supplements: Consider taking a high-quality vitamin D nutritional aid, especially during winter months to amplify your vitamin quantities.

At Vitamart, we offer a range of affordable vitamin D supplements to suit various needs and preferences.

Can You Take Too Much Vitamin D?

While vitamin D is essential for wellness, it's also possible to have “too much of a good thing”.

Vitamin D excess, also known as vitamin D toxicity, can occur when your blood levels exceed 100 ng/mL. This is typically caused by excessive supplementation rather than your diet or sunlight.

Symptoms of toxicity may include:

  • nausea
  • vomiting
  • frequent urination
  • weakness
  • kidney problems

What Is the Vitamin D Status Of Canadians?

Recent reports undertaken by the Nutrition Research Division found that approximately 33% of Canadians have insufficient vitamin D levels during the winter months.

The highest rates of deficiencies typically occur among certain populations such as older adults and those with darker skin tones.

Who Should Be Screened for Vitamin D Deficiency?

While not everyone needs routine vitamin D testing, the following groups are at greater risk of deficiency and may benefit from screening:

  • older adults
  • people with limited sun exposure
  • those with dark skin
  • individuals with certain medical conditions such as obesity or osteoporosis
  • people taking medications that affect vitamin D metabolism like anti-seizure medicines or calcium channel blockers

If you fall into any of these categories, consider discussing vitamin D testing with your doctor and increasing your intake with vitamin D chewable tablets or a vegan vitamin D option.

What Are Some Effects of Vitamin D on Health?

Not only does vitamin D play a critical role in numerous bodily functions, studies also show its involvement in preventing and alleviating serious medical diseases and disorders.

Bone Health And Osteoporosis

Vitamin D is essential for calcium absorption and bone mineralisation. Adequate levels help prevent osteoporosis and reduce the risk of fractures, especially in older adults.

Cancer

According to the National Cancer Institute, ample vitamin D can potentially assist with inhibiting cancer cell growth and promoting cancer cell death, particularly in individuals living at southern latitudes with more sun exposure.

This is especially true for reducing the possibility of certain cancers, including colorectal cancer.

Heart Disease

Vitamin D may play a role in heart health by regulating blood pressure and lowering inflammation.

In some instances, adequate amounts from vitamin D supplements can potentially minimise the dangers of cardiovascular disease.

Depression

There's growing evidence linking vitamin D and mood.

For instance, our findings show that low vitamin D levels have been associated with an increased risk of depression, particularly Seasonal Affective Disorder (SAD).

Preserving ideal volumes may help support mental health in this regard.

Multiple Sclerosis

Multiple sclerosis is a chronic disease where the immune system attacks the central nervous system, leading to symptoms like fatigue, mobility issues, and cognitive impairment.

The National Multiple Sclerosis Society asserts that ample vitamin D levels may help reduce the chance of developing multiple sclerosis.

It potentially does this by minimising MS relapse rates and disease activity through modulating immune responses and lowering inflammation.

This is particularly true of populations living farther from the equator with limited sunlight.

Type-2 Diabetes

Drawing from our experience, we've found that vitamin D may also play a role in glucose metabolism and preventing diabetes.

Maintaining normal amounts could potentially lower the likelihood of type-2 diabetes by:

  • improving insulin sensitivity
  • enhancing pancreatic beta-cell function
  • reducing inflammation

Weight Loss

While vitamin D itself doesn't lead to weight loss, it may aid the process by:

  • minimising new fat cell formation
  • improving metabolic functions
  • enhancing insulin sensitivity

Additionally, it might regulate appetite and energy balance, potentially supporting overall weight management efforts.

What Else May Be Linked with Blood Levels of Vitamin D?

Several factors can influence vitamin D quantities in the body:

Supplement Use

Regular use of vitamin D vitamins in nutritional aids is one of the most effective ways to sustain ideal levels, especially for those with limited sun exposure or dietary sources.

Many people ask, "Is 10000 IU of vitamin D safe?" While this dose can be taken under strict medical supervision, it's typically higher than what most people need.

However, supplementation exceeding 60,000 IU is highly dangerous and can lead to vitamin D toxicity.

Milk Consumption

In Canada, milk is fortified with vitamin D, making it a significant dietary source.

Regular consumption of fortified milk and other dairy products such as yoghurt can help preserve adequate vitamin D concentrations.

Sun Exposure

While your body naturally produces vitamin D when your skin is exposed to sunlight, factors such as latitude, season, and skin pigmentation can affect this process.

For example, higher latitudes and colder seasons minimise UVB radiation exposure significantly, impacting vitamin D synthesis.

In Canada, it's often difficult to get enough vitamin D from sunlight alone, especially during the colder winter months.

Additionally, higher levels of melanin in darker skin can decrease vitamin D production, resulting in deficiency.

Body Mass Index

People with a high Body Mass Index (BMI) may require more vitamin D to sustain normal blood volumes, as fat tissue can sequester this fat-soluble vitamin.

This sequestration can lead to lower bioavailability of vitamin D in the bloodstream, necessitating higher intake to achieve ample amounts.

Does Vitamin D Interact With Medications Or Other Dietary Supplements?

Vitamin D can interact with certain medications, including steroids and weight loss drugs. It may also enhance the absorption of other fat-soluble vitamins such as vitamins A, D, E, and K.

What Is A 25-Hydroxy Vitamin D Test?

A 25-hydroxy vitamin D test is a blood test that measures the level of vitamin D in your body.

Through our practical knowledge, we've discovered that it's the most accurate way to assess vitamin D status and determine if you have ideal, low, or high quantities.
