Vitamin D supplements come in two types, each with unique characteristics and benefits for the body. Understanding these forms allows people to choose the right supplement based on their individual needs and lifestyle. Here are the types:
Vitamin D2
Vitamin D2, or ergocalciferol, is a type of pure vitamin D derived from yeast and some fungi, especially mold. Though not as naturally found in the body, D2 supplements are effective at raising blood levels of vitamin D. This form of vitamin D is commonly used for individuals with dietary restrictions as it is often vegan-friendly. Vitamin D2 is also available in prescription medications for patients with specific health conditions.
Vitamin D3
Vitamin D3, or cholecalciferol, is the most naturally occurring form of vitamin D in the body. Unlike D2, which is derived from yeast and fungi, D3 is usually made from lanolin, a type of sheep wool fat. Vitamin D3 supplements are widely recognized and more commonly used than D2 in over-the-counter products. Numerous studies have demonstrated that D3 is more effective than D2 at elevating and maintaining optimal blood levels of vitamin D.
Vitamin D supplements should be taken regularly and at the right time for optimal absorption and effectiveness. This vitamin works best in combination with others, particularly vitamin C and calcium. Vitamin D3 is more effective than D2 at raising and sustaining blood levels of vitamin D, making it the preferred choice for most people. Here is how to take them properly:
Dosage
For adults, the usual daily dose of vitamin D supplements is between 600 to 800 international units (IU) or 15 to 20 micrograms (mcg). Some people may need more. People who do not get enough sunlight or have health conditions that make it hard for their bodies to absorb the vitamin are advised to take higher doses.
Timing
Vitamin D supplements are best taken during the day, with breakfast or lunch. Taking them at night may interfere with sleep for some people. Multivitamin capsule products containing vitamin D are usually designed to be taken once a day, so users should pick a time that suits them.
Pairing with Other Nutrients
Taking vitamin D supplements with vitamin C and calcium works the best. Multivitamins often contain vitamin C, while calcium is commonly found in other dietary supplements. Users should ensure that their vitamin D supplement is taken alongside breakfast or lunch with foods high in calcium, like dairy products or leafy greens.
Consistency
This vitamin is very important for bone health and the immune system, and it works best when taken consistently. It is essential to take the supplement at the same time each day to create a routine. Vitamin D supplements should be taken regularly. Skipping doses may hinder the body from reaching optimal levels and enjoying the health benefits of this vitamin.
Vitamin D supplements offer numerous benefits that extend beyond just bone health. In fact, this vitamin is crucial for bone health and supports other systems, including the immune and cardiovascular systems. Here are some of the benefits:
Bone Health
The primary benefit of vitamin D supplements is bone health. When combined with calcium, vitamin D helps build and maintain strong bones. It reduces the risk of osteoporosis and fractures in older adults. Vitamin D3, in particular, enhances calcium absorption more effectively than D2.
Immune System Support
This vitamin helps strengthen the immune system and lower the risk of autoimmune diseases. It helps the body fight off infections and may reduce the frequency of common illnesses like colds and the flu. During the COVID-19 pandemic, researchers found that adequate levels of this vitamin could lower the risk of severe infections and complications from the virus.
Mood Regulation
Vitamin D supplements can help people suffering from seasonal affective disorder (SAD) or depression. It positively affects mood and mental well-being, reducing the risk of depression and anxiety. People who get enough sunlight tend to be in better moods than those who do not, and vitamin D is thought to be the reason that. Taking vitamin D supplements regularly may help elevate mood and improve mental clarity.
Chronic Disease Prevention
Vitamin D3 may help prevent chronic diseases like cardiovascular disease, diabetes, and certain types of cancer. Researchers have found that people with higher levels of vitamin D in their blood have a lower risk of developing heart disease. It may also reduce the risk of type 2 diabetes by improving insulin sensitivity and regulating blood sugar levels.
Improved Muscle Function
Users can get stronger muscles and better performance in sports with vitamin D supplements. It aids in muscle contraction and improves athletic performance, especially in older adults who may experience a decline in muscle mass.
Vitamin D supplements should be stored properly in a cool, dry place away from direct sunlight and moisture to maintain their efficacy and extend their shelf life. Here are tips for keeping them fresh:
Keep In Original Container
The packaging is designed to protect the supplements from light and moisture. Users should always keep their vitamin D supplements in the original bottle or blister pack they came in. For people who buy vitamin D in bulk, it's essential to store the supplements in smaller, airtight containers. Exposure to air can cause the supplements to degrade, especially if they are in soft gel form.
Avoid Moisture
Water can be very harmful to vitamin D supplements, especially vitamin D3 soft gels. Moisture causes the soft gels to become sticky and go bad. To avoid this, the supplements should always be kept in a dry environment. Buyers can add desiccant packets to the storage container to absorb any moisture. These packets must be replaced regularly to stay effective.
Maintain a Cool Temperature
Heat destroys vitamin D supplements by breaking down the vitamins and reducing their effectiveness. The ideal temperature for storing vitamin D supplements is between 59°F and 77°F (15°C to 25°C). This range helps maintain the stability and potency of the supplements. Buyers should keep the supplements in a cool place away from direct sunlight. They can even store them in a drawer or a cool cabinet where the temperature remains consistent.
Avoid Extreme Temperatures
Vitamin D supplements should be kept in environments where the temperatures are not extremely high or low. Very high or low temperatures can break down the vitamins and make the supplements less effective. Try to store vitamin D supplements at a consistent temperature to maintain their potency. Avoid leaving them in areas like cars, which can experience extreme heat or cold. Air conditioners and heaters also create temperature fluctuations, so it's best to store the vitamins in a location that stays at a stable temperature, even if the rest of the house is warmer or cooler.
Regularly Check Expiration Dates
To ensure they are taking effective supplements, buyers should always check the expiration dates. Vitamin D supplements are often bad after one or two years, depending on the type and storage conditions. Expired supplements may not have the same potency or give the body the needed boost. Using expired supplements can also lead to decreased effectiveness and may cause mild gastrointestinal discomfort. Users should mark the expiration date on the container when it expires to remind them to check the container.
A1. They are good for improving bone and muscle strength, boosting the immune system, and helping the body absorb more calcium, which prevents osteoporosis and other bone-related diseases. They also boost energy levels, support heart health, and help prevent chronic diseases like diabetes and some cancers.
A2. Many fatty fish types, like salmon, mackerel, tuna, and sardines, have high levels of vitamin D. Fish liver oil, especially cod liver oil, is another rich source of this vitamin. Fortified foods like milk, orange juice, and cereals are also high in omega-3 fish oil and vitamin D.
A3. Yes, there is a difference. Omega3 vitamin D supplements contain both vitamin D and omega-3 fatty acids, usually sourced from fish oil. Regular vitamin D supplements may contain vitamin D2 or D3 alone without any other nutrients. Omega3 vitamin D supplements provide the combined benefits of vitamin D for bone health and omega-3 fatty acids for heart and brain health.
A4. Vitamin D3 (cholecalciferol) is often considered better for weight loss because it boosts the body's metabolism, increasing fat burning. D3 is also better than D2 at keeping levels of this vitamin optimal in the body, improving calcium absorption and maintaining muscle mass, which is crucial for effective weight management.
