Hello Zeromedia, Halo! Vitamin D is essential for strong bones, a healthy immune system, and overall well-being. Unfortunately, many people don’t get enough vitamin D, especially those who live in northern latitudes or spend most of their time indoors. But don’t worry, there are several ways to increase your vitamin D intake. Keep reading to discover them all.
Why Vitamin D Is Important
Vitamin D is a fat-soluble vitamin that functions like a hormone in the body. Its main role is to help the body absorb calcium and phosphorus from food, which is necessary for building and maintaining strong bones. Vitamin D also regulates the immune system, supports cardiovascular health, and may even reduce the risk of certain cancers.
What Causes Vitamin D Deficiency
- Living in areas with little sunlight
- Being housebound or institutionalized
- Wearing clothing that covers most of the skin
- Having dark skin
- Using sunscreen regularly
- Having a condition that impairs fat absorption
- Following a strict vegan or vegetarian diet
- Being overweight or obese
- Smoking
If you have any of these risk factors, you may need to pay extra attention to your vitamin D levels and take steps to increase your intake.
How to Get Vitamin D from Sunlight
The most efficient way to get vitamin D is by exposing your skin to sunlight. When your skin is exposed to UVB radiation from the sun, it converts a cholesterol derivative into vitamin D3, which then circulates in the bloodstream and gets stored in fat tissue for later use. Here are some tips for safe sun exposure:
- Expose your skin to direct sunlight between 10 a.m. and 3 p.m. when the sun is at its highest point.
- Expose as much skin as possible, ideally your arms, legs, back, and abdomen.
- Avoid getting sunburned, which can damage the skin and increase the risk of skin cancer.
- Don’t wear sunscreen all the time, as it can block UVB radiation and reduce vitamin D production. Only use sunscreen on your face, neck, and hands if you’re going to be in direct sunlight for more than 15 minutes.
- Expose your skin to sunlight regularly, at least 3 times a week for 20-30 minutes, to maintain adequate vitamin D levels.
Note: If you have very fair skin, a history of skin cancer, or live in a very sunny climate, you may need to limit your sun exposure or wear protective clothing to avoid harmful UV radiation.
How to Get Vitamin D from Food Sources
Vitamin D is naturally found in very few foods, but some are better sources than others. Here are the top food sources of vitamin D:
| Food Source | Amount of Vitamin D (IU per serving) |
|---|---|
| Fatty fish (salmon, tuna, mackerel) | 400-1000 IU per 3 oz |
| Egg yolks | 44 IU per yolk |
| Cheese | 40 IU per 1 oz |
| Mushrooms (exposed to UV light) | 400-1600 IU per cup |
| Fortified foods (milk, cereal, orange juice) | 100-120 IU per serving |
If you don’t eat fish, eggs, or dairy, you may need to take a vitamin D supplement to meet your daily needs.
How to Get Vitamin D from Supplements
Vitamin D supplements come in two forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is more effective at raising blood levels of vitamin D and is the preferred form for supplementation. Here are some guidelines for taking vitamin D supplements:
- Check with your healthcare provider before starting a vitamin D supplement, especially if you have a medical condition or take medication.
- Choose a high-quality supplement that contains vitamin D3, not D2.
- Take the supplement with a meal that contains fat, as vitamin D is fat-soluble and requires fat for absorption.
- Follow the recommended dosage on the label or as advised by your healthcare provider.
- Get your blood levels of vitamin D checked regularly to ensure you’re not taking too much or too little.
FAQ about Vitamin D
Q: Can you get too much vitamin D?
A: Yes, it’s possible to take too much vitamin D, which can lead to vitamin D toxicity. Symptoms of vitamin D toxicity include nausea, vomiting, constipation, weakness, and confusion. It’s important to get your blood levels of vitamin D checked regularly and not exceed the recommended daily intake.
Q: Can you get vitamin D from tanning beds?
A: Yes, tanning beds emit UV radiation that can stimulate vitamin D production in the skin. However, tanning beds are not recommended as a source of vitamin D because they increase the risk of skin cancer and premature skin aging.
Q: Can you get enough vitamin D from your diet?
A: It’s difficult to get enough vitamin D from diet alone, especially if you’re a vegan or vegetarian. Most people need to supplement with vitamin D or get sun exposure to maintain adequate levels.
Q: Does vitamin D prevent COVID-19?
A: While some studies suggest that vitamin D may have a protective effect against respiratory infections, including COVID-19, more research is needed to confirm this. It’s always important to follow public health guidelines for preventing the spread of COVID-19, including wearing a mask, washing your hands, and social distancing.
