Vitamin D is a fat-soluble vitamin that plays an important role in calcium absorption, bone health, and immunity. Our skin produces vitamin D when exposed to sunlight, but many people avoid the sun or use sunscreen because of the risk of skin cancer, which prevents the body from producing vitamin D. Many types of milk and dairy products contain vitamin D, along with oranges. juice. However, many are deficient in vitamin D and need to take supplements. There are two types of vitamin D supplements: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol), and it is important to know the difference when deciding which vitamin D supplement to take.
Now Foods Vitamin D3
The term vitamin D is a misnomer, because you won’t find anything labeled “vitamin D” in the vitamin aisle of a drugstore. However, your choice is vitamin D2 (What is vitamin D2?) or vitamin D3 (What is vitamin D3?). Usually, when someone says vitamin D, they mean vitamin D2. For the purposes of this article, when referring to vitamin D, it will refer to vitamin D2. The names can be confusing, as patients often look for vitamin D in pharmacies and are surprised to find D2 and D3.
Vitamin D (D2) comes from plants, such as wild mushrooms, and from fortified foods, such as milk or wheat. Strength is usually measured in International Units, abbreviated “IU” on the label. The 50,000 IU capsules are prescription only, while lower strengths are available over the counter. Vitamin D is inexpensive to produce, so it is often found in fortified foods.
Vitamin D3 is usually obtained from animal sources such as fish oil, fatty fish, liver and eggs. When the skin is exposed to the sun, it produces vitamin D3. Therefore, it is sometimes called the sunshine vitamin. Its strength is also measured in international units. All forms of vitamin D3 are available over the counter.
Vitamins D and D3 are ultimately metabolized in inactive metabolites to calcitriol. Calcitriol is the main health effect of vitamin D in the body. Calcitriol improves calcium absorption, increases absorption of calcium and phosphorus in the intestine, and increases calcium from bones to plasma. Calcitriol even inhibits the growth of cancer cells. Vitamins D and D3 ultimately provide the body with an important metabolite, calcitriol.

Prescription vitamin D2 is used to treat hypoparathyroidism (lack of parathyroid hormone secretion), vitamin D-dependent rickets, and hypophosphatemia (low levels of phosphorus in the blood). It is often used for vitamin D deficiency in prescription and over-the-counter products. The FDA does not allow medical claims for over-the-counter vitamin supplements, even though their use is common, but they are considered off-label.
Not all types of vitamin D3 supplements are available over the counter and therefore the FDA does not allow testing. However, vitamin D3 is often used off-label to treat hypoparathyroidism, vitamin D deficiency, and prevent osteoporosis.
In March 2020, the World Health Organization (WHO) declared a global pandemic due to the spread of SARS-CoV-2, commonly known as COVID-19. Due to the lack of clear guidelines for treatment and the waiting time for a vaccine to be available, attention has shifted to strengthening our natural defenses. Vitamin D plays an important role in the fight against COVID-19.
The COVID-19 virus promotes the release of inflammatory cytokines. This activity causes some of the most serious respiratory illnesses, and for some, it can be fatal. Vitamin D is a natural defense against this process because it prevents part of the cytokine release caused by the COVID-19 virus. Unfortunately, many Americans are vitamin D deficient and need supplements to meet recommended levels. Supplements including vitamin D, C and zinc are often recommended to strengthen our ability to fight against COVID-19.

It’s been more than two years since the disease, and we’re starting to have a deeper appreciation for high vitamin D and severe COVID symptoms. A prospective study examined the relationship between vitamin D during infection and symptom severity. A vitamin D level of 30 nanograms per milliliter (ng/ml) of blood or more. There is a correlation between vitamin D below 20 ng/ml and severe COVID symptoms. Although these cases were considered more serious, there was no association with increased mortality based on the 21 eligible studies considered for this analysis.
Based on this information, another group of researchers evaluated the short-term use of vitamin D in Covid patients. The SHADE study showed that this type of vitamin D supplementation was associated with reduced levels of fibrinogen.
For all the data showing a connection between vitamin D and the severity of Covid, there are researchers who show that there is no real connection between vitamin D levels and the problems and severity of Covid. It will take years to understand the complex relationship, but we know that many Americans are deficient in vitamin D. Regardless of covid, vitamin D health plays an important role in our health and immunity. Talk to your healthcare provider to see if vitamin D supplements are right for you.

Vitamins D2 and D3 are absorbed into the bloodstream, where they are metabolized by the liver into 25-hydroxyvitamin D2 and 25-hydroxyvitamin D3, collectively known as 25D or calcifediol. Calcifediol is a vitamin D complex that circulates in the blood, and its levels accurately reflect the body’s vitamin D stores. Calcifediol is often referred to as vitamin D. When your doctor orders a lab test to check your vitamin D level, he measures the level of calcifediol (25D). Calcifediol is the precursor of calcitriol, the most potent metabolite of vitamin D and D3.
Several studies have been conducted to compare whether vitamin D2 or D3 supplementation leads to higher blood calcifediol levels. A study published by the National Institutes of Health looked at older women, especially those who were deficient in vitamin D. The effects of receiving high doses of vitamin D2 or vitamin D3 on calcifediol were compared. The study found that circulating calcifediol was twice as much vitamin D3 as vitamin D2 in this patient population.
In a clinical trial of 50,000 IU doses of vitamin D2 and vitamin D3 twice a week for 10 weeks in equal proportions, vitamin D3 was found to be superior to the production of 25D or calcifediol at high levels.
Based on laboratory tests to measure vitamin D levels, your doctor can determine total 25D or free 25D, or both. There is a debate about which test is best for storing vitamin D in the body, but studies show that vitamin D is better. D3 in a two-part lift.
