What is Vitamin D?
Vitamin D, also known as the “sunshine vitamin,” is a fat-soluble vitamin. It’s unique because your skin synthesises it in response to sunlight exposure. It also exists in certain foods and supplements. It is unique because the body can produce it when the skin is exposed to sunlight. However, it can also be obtained through certain foods and supplements. Vitamin D is vital for several bodily functions, including bone health, immune function, and overall cell growth.
Where do you get Vitamin D from?
- Sunlight: Your body produces vitamin D naturally when it’s directly exposed to sunlight. The amount of vitamin D your skin makes depends on many factors, including the time of day, season, latitude, and skin pigmentation.
- Food: Very few foods in nature contain vitamin D. The flesh of fatty fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources. Small amounts of vitamin D are found in beef liver, cheese, and egg yolks. Some mushrooms also provide vitamin D, but in a form that humans can’t absorb as effectively.
- Fortified Foods and Supplements: In many countries, foods like milk, orange juice, yoghurt, and cereals are fortified with vitamin D. Also, vitamin D supplements are widely available and can be a good way to ensure you’re getting enough, particularly if you’re at risk of deficiency.

Key Functions of Vitamin D
Bone Health
Vitamin D helps the body absorb calcium and phosphorus, two minerals that are essential for the development and maintenance of strong bones and teeth. It helps prevent bone-related conditions like osteoporosis and rickets, which can cause bones to become weak or deformed.Immune System Support
Vitamin D is crucial for the proper functioning of the immune system. It helps activate immune cells, such as T-cells, which are important for defending the body against infections and diseases. Adequate Vitamin D levels may help reduce the risk of chronic conditions like autoimmune diseases and infections.Mood Regulation and Mental Health
Vitamin D is thought to play a role in regulating mood and warding off conditions like depression. Low levels of Vitamin D have been linked to mood disorders, and some studies suggest that increasing Vitamin D intake may help improve symptoms of depression and anxiety.Muscle Function
Vitamin D supports the function of muscles, as it plays a role in muscle contraction. It is especially important for maintaining muscle strength, particularly in older adults, to prevent falls and injuries.Cell Growth and Repair
Vitamin D is involved in the regulation of cell growth and repair, which is essential for overall body health. It helps regulate the cell cycle, and sufficient Vitamin D levels are important for the maintenance and regeneration of cells throughout the body.
Deficiency and Its Effects
A Vitamin D deficiency can lead to a variety of health problems, including:
- Rickets: A condition in children characterised by soft and weak bones, leading to deformities.
- Osteoporosis and Osteomalacia: In adults, a lack of Vitamin D can lead to weakened bones, increasing the risk of fractures and pain.
- Weakened Immune System: A deficiency can impair the body’s ability to fight infections.
- Muscle Weakness and Pain: Low Vitamin D levels are linked to muscle weakness, cramps, and fatigue.
What are Vitamin injections, and when should a patient consider them?
Vitamin D injections are a method of delivering a concentrated dose of vitamin D directly into the bloodstream. They are typically recommended when a patient has a severe deficiency in vitamin D. Injections are considered when oral supplements are not effective or when rapid correction of vitamin D levels is necessary, as they can provide a more immediate and efficient way to raise vitamin D levels in the body. It’s important to consult with a healthcare professional to determine if vitamin D injections are appropriate for a specific patient’s needs. Please note, that Vitamin D injections are not suitable for those who are pregnant or for those actively trying to conceive.
What are the benefits of Vitamin D injections?
It can help in maintaining healthy bones and teeth, supporting the immune system, brain, and nervous system. It can regulate insulin levels and support diabetes management. It’s also beneficial for lung function and cardiovascular health.
How often should you get Vitamin D injections?
Typically given every 3-6 months, blood levels between injections including your vitamin D level and calcium may be needed to monitor response to the injection.
What are the side effects of Vitamin D injections?
Side effects are generally rare but can include nausea, fatigue, and irritability. In more serious cases, it can cause high calcium levels in the blood. Always consult your healthcare provider if you experience side effects.
Who should consider Vitamin D injections?
People with Vitamin D deficiency or those who have difficulty absorbing Vitamin D through diet or sunlight, such as older adults or those with certain medical conditions like coeliac disease, should consider Vitamin injections.
Can Vitamin D injections help with bone health?
Yes, Vitamin D helps the body absorb calcium and phosphorus, which are essential for bone health. Thus, Vitamin injections can support bone health and prevent conditions like osteoporosis.
What is the difference between Vitamin D injections and oral supplements?
Vitamin injections ensure direct absorption into the bloodstream, which may be beneficial for individuals with malabsorption issues. Oral supplements, on the other hand, are easy to take but their effectiveness can depend on individual absorption capabilities.
How long does it take for a Vitamin D injection to work?
The time for a Vitamin D injection to take effect can vary based on individual factors, but generally, the effects can be noticed within a few weeks of regular injections.

Common Q&A about Vitamin D
Vitamin D is a fat-soluble vitamin that plays a crucial role in maintaining bone health by aiding in the absorption of calcium. It also supports immune function, reduces inflammation, and may help prevent certain chronic diseases.
Vitamin D can be obtained through sunlight exposure, dietary sources (like fatty fish, fortified foods, and egg yolks), and supplements. Your body naturally produces vitamin D when your skin is exposed to sunlight.
Common symptoms of vitamin D deficiency include fatigue, bone pain, muscle weakness, and mood changes like depression. Severe deficiency can lead to rickets in children and osteomalacia or osteoporosis in adults.
The recommended daily intake varies by age and health status. Generally:
- Infants (0–12 months): 400 IU (10 mcg)
- Children and Adults (1–70 years): 600 IU (15 mcg)
- Adults over 70 years: 800 IU (20 mcg)
- Pregnant or breastfeeding women: 600 IU (15 mcg)
Yes, excessive intake of vitamin D, especially through supplements, can lead to toxicity. This may result in hypercalcemia (high calcium levels), causing nausea, vomiting, weakness, and kidney damage.
People at higher risk include those with limited sun exposure, darker skin tones, older adults, people with certain medical conditions (like Crohn’s or celiac disease), and individuals who are overweight or obese.
A blood test measuring the level of 25-hydroxyvitamin D is the most accurate way to assess vitamin D deficiency. A level below 20 ng/mL typically indicates deficiency, while 20–50 ng/mL is considered adequate for most people.
Yes, vitamin D plays an essential role in supporting immune function. Studies suggest it may help reduce the risk of infections like colds, flu, and respiratory illnesses, particularly in those who are deficient.
If you are at risk for deficiency or have limited sun exposure, you might benefit from supplements. However, it’s best to consult a healthcare provider for advice, as vitamin D needs can vary based on individual health factors.
While generally safe, some individuals may experience mild side effects such as soreness at the injection site, dizziness, or allergic reactions. Severe side effects are rare, but it’s essential to monitor your body’s response and communicate with your healthcare provider.
