Benefits of Vitamin D and How to Increase It

Vitamin D, often referred to as the "sunshine vitamin," plays a pivotal role in our overall health and well-being. Despite its importance, Vitamin D deficiency is a surprisingly common issue worldwide, affecting people of all ages. This essential nutrient is not only crucial for maintaining healthy bones but also plays a vital role in immune function, mood regulation, and the prevention of chronic diseases. In this blog post, we'll explore the myriad benefits of Vitamin D and provide practical advice on how to naturally increase your levels to support optimal health.

Benefits of Vitamin D

Bone Health

Vitamin D is fundamental in regulating calcium and maintaining phosphorus levels in the blood, two factors that are extremely important for maintaining healthy bones. Without sufficient Vitamin D, our bodies cannot absorb calcium, leading to softer bones, a condition known as rickets in children and osteomalacia in adults. Moreover, adequate levels of Vitamin D are crucial in preventing osteoporosis and fractures in older adults.

Immune System Support

Vitamin D is a powerful immune system booster. It plays a significant role in immune response and can help protect against illnesses by enhancing the pathogen-fighting effects of monocytes and macrophages — white blood cells that are important parts of your immune defense — and decreasing inflammation.

Mood Regulation and Depression Prevention

Research suggests a link between Vitamin D deficiency and depression. Vitamin D receptors are present in many parts of the brain, influencing the brain's ability to regulate mood and thought processes. Supplementing with Vitamin D has shown promise in reducing the symptoms of depression and supporting overall mental health.

Supporting Diabetes Management and Prevention

Emerging research indicates that Vitamin D may play a role in reducing the risk of type 2 diabetes. Its effect on insulin sensitivity and glucose metabolism could help in the management and prevention of diabetes, highlighting the importance of maintaining adequate levels of this nutrient.

Sources of Vitamin D

Vitamin D is unique among vitamins because it can be synthesized by the body when sunlight hits the skin. However, depending on geographical location, skin color, sunscreen use, and lifestyle, natural synthesis might not be sufficient. Understanding the different sources of Vitamin D is crucial for ensuring adequate levels.


The most natural way to get Vitamin D is by exposing your bare skin to sunlight. When your skin is exposed to UVB rays from the sun, it produces Vitamin D naturally. However, the amount of Vitamin D your skin makes depends on the time of day, season, latitude, and your skin melanin content. Generally, 10 to 30 minutes of midday sun exposure several times a week may suffice for adequate Vitamin D synthesis, but this varies greatly.

Food Sources

While few foods naturally contain Vitamin D, some can be significant sources:

Fatty fish such as salmon, mackerel, and sardines are among the best sources.

Egg yolks from chickens that have been fed Vitamin D-rich feed.

Fortified foods are common and include milk, orange juice, and cereals, which have Vitamin D added to them.


Vitamin D supplements can be an effective way to ensure adequate intake for those with limited sun exposure or dietary restrictions. Vitamin D3 supplements (cholecalciferol) are often recommended over Vitamin D2 (ergocalciferol) because D3 is the form naturally produced by the body in response to sun exposure and may be more effective in raising blood levels.

How to Increase Your Vitamin D Levels

Increasing your Vitamin D levels can be straightforward with the right strategies.

Here are practical ways to boost your intake:

Safe Sun Exposure

Aim for moderate sun exposure, about 10-30 minutes several times a week, depending on your skin’s sensitivity and local UV index. Remember to expose large areas of your skin without sunscreen during this time, but avoid sunburn by not staying out too long.

Dietary Strategies

Incorporate Vitamin D-rich foods into your diet. Consider having fatty fish twice a week, choosing fortified products, and using mushrooms that have been exposed to sunlight. These small dietary adjustments can significantly impact your Vitamin D levels.


Supplements offer a practical solution for those who struggle to get enough Vitamin D through sunlight and diet. It's essential to choose the right dosage, often between 600 to 800 IU per day for most adults, but the tolerable upper level of 4,000 IU may be safe if you're deficient or have higher needs. Always consult with a healthcare provider before starting any supplementation.
