How Do Vitamin D2 And D3 Differ
There are two main kinds of vitamin DD2 and D3 . D2 is found in plant foods, including fungi like mushrooms and yeasts. D3 is only available in animal foods, and its the type of vitamin D your body makes on its own when its exposed to UV light.
D2 is inexpensive to produce, so its often added to foodssuch as milkto boost their vitamin D content. However, D2 is not as well absorbed by the body as D3. Some studies indicate that D3 may be almost twice as effective at raising levels of vitamin D in the blood as D2 . If you supplement with vitamin D to achieve optimal levels, nutrition experts generally recommend choosing vitamin D3 supplements.
According to an American Journal of Clinical Nutritionreport, medical literature regarded D2 and D3 as equivalent and interchangeable for many years, yet this presumption of equivalence is based on studies of rickets prevention in infants conducted 70 years ago
Despite an emerging body of evidence suggesting several plausible explanations for the greater bioefficacy of vitamin D3, the form of vitamin D used in major preparations of prescriptions in North America is vitamin D2.
What Is Vitamin D3 And How Is It Different From Vitamin D
Vitamin D may sound like a singular item, but it’s actually a group of vitamins. Dr. Ungerleider told POPSUGAR that this group of vitamins “shares similar chemical structures that are fat-soluble and help the body absorb calcium, regulate bone growth, and play a role in the function of our immune system.” Vitamin D can also reduce inflammation.
The two major vitamins in this group are vitamin D2 and vitamin D3. Vitamin D2 is produced by plants, while vitamin D3 is made in the epidermis when the skin is exposed to sunlight. That’s why it’s important to make sure you’re getting enough sun, though Dr. Ungerleider noted that you can also get vitamin D3 from eating salmon, mushrooms, and egg yolks.
If you’re struggling to get enough vitamin D naturally, your doctor may recommend a supplement. Research suggests that vitamin D3 is a more effective supplement than vitamin D2, which is why you’ll find it more frequently on store shelves. Just be sure to check the dosage with your doctor and have your levels retested to ensure you’re staying in a healthy range.

What Are The Differences Between Vitamin D And Vitamin D3
Both Vitamin D and Vitamin D3 are processed in the body by the liver to 25-hydroxyvitamin D, which increases 25D levels.
Vitamin D2 referred to as Vitamin D, is largely human-made and derived from plant sources. Vitamin D is produced by plants when theyre exposed to UV light .
Vitamin D2 is commonly found in fortified foods, such as milk and cereal products or in supplement form. While this form is often pressed into a tablet supplement and consumed by people adhering to restricted diets, your body doesnt actually produce this form of vitamin D naturally, making it a poor quality nutrient when it comes to fulfilling your daily requirement of vitamin D .
In food, vitamin D is measured in micrograms with the suggested daily intake of 25-100 micrograms per day is needed to maintain optimal blood levels .
Examples of Foods High in Vitamin D:
- Fatty Fish = 9-17 micrograms per 3oz serving
- Mushrooms = 7.9 micrograms per ½ cup serving
- Whole Milk = 3.2 micrograms per 1 cup serving
- Orange Juice = 2.5 micrograms per 1 cup
- Eggs = 1.1 micrograms per 1 large egg
As you can see from the examples above, even the best food source of vitamin D doesnt contain nearly enough micrograms to provide sufficient delivery and function within the human body. Vitamin D2 is used as an inexpensive, low quality, and less effective option to boost nutrient quality as compared to Vitamin D3 .
What Are The Side Effects Of Taking Too Much Vitamin D
If you take too much vitamin D, you may experience symptoms such as weakness, fatigue, sleepiness, headache, loss of appetite, dry mouth, and dizziness. These side effects are usually mild and go away on their own.

Do I Have A Vitamin D Deficiency
Most people living in first-world countries dont have many vitamin deficiencies. We can get most of the nutrients we need through food alone, and many foods have vitamins added to them to ensure that we get enough. Vitamin D deficiency, however, is still rampant, even among otherwise healthy people.
The main reason why is lack of sun exposure. Contrary to what you might think, just walking around outside on a sunny day usually isnt enough, even if you live on a tropical island. Clouds and shade dramatically cut down on ultraviolet lightthe stuff that your skin needs to produce vitamin Dand window glass blocks it completely. Furthermore, the National Institutes of Health explain that wearing sunscreen with an SPF of eight or more wont allow your body to absorb enough light to make D, although its obviously important to use some anyway to avoid sunburn and long-term skin damage.
Ethnicity also plays a factor. Melanin is a pigment that darkens the skin, but it also reduces the skins ability to absorb vitamin D. African Americans and Hispanics typically have more melanin than white people, so they tend to be more deficient.
Senior citizens are also in jeopardy. A trial in the American Journal of Geriatric Pharmacotherapy stated that elderly subjects had insufficient D levels, despite vitamin D intake consistent with national recommendations.

That means you could equally safely take a supplement of 20 micrograms a day or 500 micrograms once a month.
Common Side Effects Of Vitamin D Vs D3
There are no common side effects to therapy with either vitamin D2 or D3. Side effects related to vitamin D are the result of hypervitaminosis D, an extremely rare condition that occurs when you intake too much vitamin D. This is sometimes seen in patients who take megadoses of vitamin D, leading to vitamin D toxicity. The result is a build up of dangerously high levels of calcium in the blood which can lead to nausea, vomiting, constipation, and frequent urination. If left untreated, irreversible renal failure can occur along with calcification of organs and soft tissues.
The following table lists side effects related to hypervitaminosis D, not normal vitamin D supplementation. More information on vitamin D toxicity may be obtained from your doctor or pharmacist, as this may not be a complete list.

Your Skin Produces Vitamin D3
Another significant difference between D1 and D2 and D3 is that your skin produces Vitamin D3 when exposed to sunlight, which is the primary source of vitamin D for many people. To be more specific, the ultraviolet B radiation in sunlight causes your skin to produce vitamin D3 from naturally occurring 7-dehydrocholesterol compounds in your skin.
In laymans terms, sunlight equals vitamin D, though many people dont get their recommended daily allowances this way because they spend too much time indoors or cover up when outside. If you struggle to get enough sun or are worried about your vitamin D levels during winter, you may need to boost your intake with manufactured supplements.
Vitamin D3 Is Formed In Your Skin
Your skin makes vitamin D3 when its exposed to sunlight.
Specifically, ultraviolet B radiation from sunlight triggers the formation of vitamin D3 from the compound 7-dehydrocholesterol in skin .
A similar process takes place in plants and mushrooms, where UVB light leads to the formation of vitamin D2 from ergosterol, a compound found in plant oils .
If you regularly spend time outdoors, lightly clad and without sunscreen, you may be getting all the vitamin D you need.
In Indian people, an estimated half an hour of midday sun twice a week provides the adequate amount .
Just keep in mind that this duration of exposure does not apply in countries farther away from the equator. In these countries, you may need more time to achieve the same results.
Nevertheless, be careful not to spend too much time in the sun without sunscreen. This is especially important if you have light-colored skin. Sunburns are a major risk factor for skin cancer .
Unlike dietary vitamin D, you cannot overdose on vitamin D3 produced in your skin. If your body already has enough, your skin simply produces less.
That said, many people get very little sun. They either work indoors or live in a country that doesnt get much sunlight during the winter. If this applies to you, make sure to regularly eat plenty of food rich in vitamin D.
Summary Your skin produces vitamin D3 when you spend time in the sun. In contrast, vitamin D2 is produced by plants and mushrooms exposed to sunlight.

Is Vitamin D Or D3 More Effective
Vitamin D2 and D3 are absorbed into the bloodstream where they are metabolized by the liver into 25-hydroxyvitamin D2 and 25-hydroxyvitamin D3, otherwise collectively known as 25D or calcifediol. Calcifediol is the vitamin D complex circulating in your blood, and its levels directly reflect your bodys stores of vitamin D. Calcifediol is commonly referred to as the active form of vitamin D. When your doctor orders lab tests to check your vitamin D levels, they are measuring your calcifediol levels.
There have been several studies comparing whether supplementation with vitamin D2 or D3 produces a higher blood level of calcifediol. A study published by the National Institutes of Health was conducted in elderly, post-menopausal women who had been identified as vitamin D deficient. It compared the effects of receiving a single high dose of vitamin D2 or vitamin D3 on calcifediol levels. The study concluded that vitamin D3 produced about twice the amount of circulating calcifediol in this patient population versus that of vitamin D2.
In a separate clinical trial comparing a 10-week regimen of twice weekly 50,000 IU dosing of both vitamin D2 and vitamin D3 in demographically matched groups, vitamin D3 was also found to be superior in producing higher levels of 25D, or calcifediol.
