What Does Vitamin D Do?

It's essential for maintaining bone density and preventing conditions like osteoporosis and rickets. Additionally, vitamin D supports the immune system, helping to fend off illnesses and infections.

Vitamin D is also crucial for brain and nervous system health. It regulates mood and may reduce the risk of depression. Moreover, it assists in regulating insulin levels, supporting diabetes management. Vitamin D with iron is beneficial for those with anemia, enhancing iron absorption.

Lung function and cardiovascular health also benefit from adequate vitamin D levels. According to the Mayo Clinic, vitamin D deficiency can lead to severe health issues, including cardiovascular diseases.

The Importance of Vitamin D to Health

Vitamin D is crucial for overall health. It helps our bodies absorb calcium, promotes bone and teeth health, supports immune function, and regulates mood.

Without adequate vitamin D, we can face various health issues.

Vitamin D Deficiencies

A lack of vitamin D can lead to various health issues. Symptoms of deficiency include fatigue, bone pain, muscle weakness, and mood changes, such as depression. In severe cases, it can cause rickets in children and osteomalacia in adults.

According to Medical News Today, vitamin D deficiency is linked to an increased risk of chronic diseases, including cardiovascular diseases and certain cancers.

Ensuring adequate vitamin D levels is essential, especially for those at higher risk of deficiency. We recommend incorporating high-quality supplements, like our vitamin D capsules and vitamin D2 supplements, to maintain optimal health.

What to Look For in Vitamin D Supplements

Choosing the right vitamin D supplement can have a significant impact your health.

This section will help you understand the key factors to consider when selecting a vitamin D supplement, including the form of vitamin D and the ingredients used.

By understanding these aspects, you can make an informed choice that best suits your needs.

When choosing a vitamin D supplement, consider the form. Vitamin D is available in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol).

The difference between vitamin D and D3 is significant because vitamin D3 is more effective at raising the body's vitamin D levels.

Vitamin D3 is the preferred choice for supplementation because it is more efficient at maintaining adequate levels in the bloodstream.


Look for supplements that contain minimal fillers and artificial ingredients. High-quality supplements should also be free from allergens like gluten and dairy.

Pure, high-quality ingredients ensure better absorption and reduce the risk of adverse reactions.

Our vitamin D supplements are formulated with these principles in mind, offering you the best options for maintaining your health.

Who Needs to Take Vitamin D?

Vitamin D is essential for everyone, but certain groups are at higher risk of deficiency and may benefit more from supplementation.

This section will highlight those who need vitamin D the most, focusing on people at risk of deficiency and providing advice for infants and young children.

People At Risk Of Vitamin D Deficiency

Individuals who are at a higher risk of vitamin D deficiency include those with limited sun exposure, older adults, people with darker skin, and those who are overweight.

Canadians, in particular, are at risk due to the long winters and limited sunlight.

These factors can significantly reduce the body's ability to produce vitamin D naturally. For these individuals, supplements are often necessary to maintain adequate levels and prevent associated health issues.

Advice For Infants And Young Children

Infants and young children require adequate vitamin D for proper growth and development. Health Canada recommends that breastfed infants receive a daily vitamin D supplement of 400 IU to ensure they get enough of this vital nutrient.

This supplementation supports bone health and immune function during the critical stages of early development.

Our range of vitamin D for kids is ideal for ensuring that the youngest members of your family receive the necessary nutrients for healthy growth.

What Are the Benefits of Vitamin D Supplements?

Taking vitamin D supplements can help prevent deficiencies, support bone health, boost the immune system, and improve mood.

It's especially beneficial during the winter months, when sunlight exposure is minimal.

Preventing Deficiencies

Vitamin D supplements are crucial in preventing deficiencies, especially for those with limited sun exposure or dietary intake.

Adequate supplementation can prevent the health issues associated with low vitamin D levels, such as rickets in children and osteomalacia in adults.

Supporting Bone Health

Vitamin D is essential for calcium absorption, which is vital for maintaining strong bones and teeth. It helps prevent osteoporosis and fractures, particularly in older adults.

Supplementation ensures that the body has enough vitamin D to maintain bone density and health.

Boosting The Immune System

Vitamin D plays a key role in supporting the immune system. It helps the body fight off infections and reduces the risk of chronic diseases.

Our research indicates that adequate vitamin D levels are associated with a lower risk of respiratory infections and autoimmune diseases.

Improving Mood

Vitamin D can improve mood and reduce the risk of depression. It regulates the production of neurotransmitters, such as serotonin, which affect mood. This is particularly important during the winter months, when reduced sunlight can lead to seasonal affective disorder (SAD).

How Much Vitamin D Do We Need?

The recommended daily allowance of vitamin D varies by age, but adults generally need around 600 to 800 IU per day. However, some individuals may require higher doses based on their health needs and doctor's recommendations.

Those over the age of 70 are recommended to take up to 800 IU daily, while younger adults typically need around 600 IU. Specific health conditions, lifestyle factors, and geographic location can influence these requirements, making personalized advice essential.

Our selection of vitamin D supplements at Vitamart provides various strengths to meet these diverse needs, ensuring that you can find the right dosage to maintain your health.

Choosing The Right Supplement

When selecting a vitamin D supplement, it's important to consider one that contains vitamin D3 for optimal absorption and effectiveness.

Our range of vitamin D3 supplements is formulated to provide you with the best possible health benefits, ensuring that your vitamin D levels remain at an optimal level year-round.

Different Types of Vitamin D Supplements

Choosing the right type of vitamin D supplement is crucial for maximizing its health benefits. This section will explain the differences between vitamin D2 and D3 supplements, helping you make an informed decision.

Vitamin D2 Supplement

Vitamin D2 (ergocalciferol) is derived from plant sources such as mushrooms and is commonly used in fortified foods. While it can help increase vitamin D levels, studies show it is not as effective as vitamin D3 in maintaining adequate vitamin D levels in the body.

Vitamin D2 is less potent and has a shorter duration of action compared to D3. Despite this, it remains a viable option, especially for those who prefer plant-based supplements.

Vitamin D3 Supplement

Vitamin D3 (cholecalciferol) is derived from animal sources like fish oil or lanolin from sheep's wool. It can also be synthesized from lichen for vegan supplements. Vitamin D3 is more effective at raising and maintaining vitamin D levels in the body.

This makes it the preferred choice for most individuals. Vitamin D3 is almost twice as effective as D2 in boosting the body's vitamin D levels, ensuring better overall health benefits.

For those seeking high-quality options, our range of vitamin D3 supplements offers effective solutions to maintain optimal vitamin D levels.
