Difference Between Vitamin D and Vitamin D3

Its hard to get enough vitamin D from sunshine, but its even harder to get it from foodat least the way most people eat. The best source of dietary D is from fish livers, such as cod liver oil, but now ask yourself when was the last time you ate cod liver oil?

Mackerel, salmon, sardines, swordfish, trout, and tuna all offer D, as do mushrooms and eggs. If you eat them regularly, youll meet the government-recommended requirement, but if youre in the camp that thinks 600 IU is too low, youll need to be more aggressive to hit your D goals. Dairy products and cereals are fortified with vitamin D, which helps, but one review, and Harvard University, determined that supplementation with a multivitamin or concentrated vitamin D capsule provides a better insurance policy.

Of course, you shouldnt completely avoid the sun. According to a report in Alternative Medicine Review, the health benefits accruing from moderate UV irradiation, without erythema or excess tanning, greatly outweigh the health risks, with skin pigmentation providing much of the protection.

Can Vegans Take A Vitamin D Supplement

Vegans can be more susceptible to a vitamin D deficiency. The double whammy of not getting enough sunlight during the winter months and not being able to eat most of the food sources of vitamin D can make it a little more difficult.

However, even with meat, dairy and eggs off the menu, there are still natural vegan sources of vitamin D like mushrooms for vitamin D2 and lichen for vitamin D3.

As these are limited, a vitamin D supplement is recommended. Especially for vitamin D3 as we dont think many vegans will be chowing down on some lichen!

Does Vitamin D3 Give You Energy

Increasing vitamin D intake is thought to improve energy. A clinical trial was done examining fatigue levels in patients who were identified as vitamin D deficient. These patients were given vitamin D3 supplementation to increase blood levels of vitamin D, and the results showed a significant improvement in fatigue levels. Scientists have shown this may be due to vitamin Ds effect at the cellular level where it augments mitochondrial oxidative phosphorylation in skeletal muscle. This decreases muscle fatigue.

Vitamin D3 Is Formed In Your Skin

The 8 Differences Between Vitamins D3 and D2: (by Abazar Habibinia, MD):

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 D3 The Same As Vitamin D

Is Vitamin D2 The Same As Vitamin D3

What is vitamin D2 and D3?

Vitamin D2 and D3 are slightly different. Both forms raise your blood vitamin D levels, and both can treat and prevent rickets from vitamin D deficiency. However, studies have found that vitamin D3 effectively raises blood vitamin D levels for a longer period than vitamin D2.

Additionally, vitamin D2 and D3 are derived from different sources. Vitamin D2 is plant-based. It is made by exposing ergosterol found in yeast to ultraviolet light. Vitamin D2 can also be found in some types of mushrooms. Vitamin D3 is sourced from sheep lanolin. It is made by exposing the lanolin to UV radiation to convert the cholesterol in lanolin to vitamin D3.

Vitamin D supplements can contain either vitamin D2 or D3. However, most over-the-counter preparations contain vitamin D3.

What Is The Difference Between Vitamins D2 And D3

Past studies suggested that vitamin D3 may be more effective than vitamin D2 in establishing normal vitamin D stores. However, a study by Holick and colleagues demonstrated that vitamin D2 and vitamin D3 appear to be equipotent in raising 25D concentrations when they are given in daily doses of 1000 IU.

Vitamin D Can Be Produced In The Skin

When exposed to the radiation from sunlight our skin will start producing vitamin D3 from a compound 7 dehydrocholesterol in the skin. very similar to the act that plants and mushrooms do, though they produce vitamin D2 from a compound called ergosterol.

If you often spend time outdoors with very little or without sunscreen, then you might be getting all the vitamin D that you need. In some hotter climates, spending just 30minutes outside in the midday sun twice a week should be enough. Keep in mind in cooler countries this time will vary.

Anothing thing worth noting is unlike vitamin D from your diet you cant overdose on sunlight vitamin D, your skin will simply produce less once youve had enough.

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.

What Kind Of Vitamin D Is Best

The recommended form of vitamin D is vitamin D3 or cholecalciferol. This is the natural form of vitamin D that your body makes from sunlight. Supplements are made from the fat of lambs’ wool.

However, a clinical study reported in 2008 suggested that vitamin D2 works as well as vitamin D3.

Many supplements contain vitamin D as vitamin D2 or calciferol. It’s derived from irradiated fungus. Because this is not the form of vitamin D naturally made by your body, WebMD nutritionist Kathleen M. Zelman, MPH, RD, recommends using the D3 form for those taking vitamin D supplements.

Because of its potency, different forms of vitamin D are used in prescription medications. If you have a prescription for one of these medications, do not switch to another form of vitamin D without checking with your doctor.

How Much Vitamin D Should I Take

What is the difference between Vitamin D and Vitamin D3 ...

There is some controversy about whether people should take vitamin D as an oral supplement or just improve their level of sun exposure, while still staying sun safe.

An estimated 90% of vitamin D in our bodies is made when our skin is exposed to sunlight, which means our diet only contributes a small amount. However, there are certain groups of people, such as babies, young children, people with mental or physical disabilities, people with malabsorption syndromes, the elderly, and people who cover their skin for religious or cultural reasons that are at high risk of becoming vitamin D deficient.

The recommended daily intake of vitamin D is:

  • Aged birth to 1 year: 400 IU
  • Aged 1-70 years: 600 IU
  • Aged > 70 years: 800 IU

The safe upper limit of vitamin D is 4,000 IU/day for adults. But even though dosages above this amount are not recommended, doctors may still prescribe them for people who are vitamin D deficient. The upper limit for children is 1000IU for infants up to 6 months 2,500IU for toddlers up to 3 years 3,000IU for children aged 4-8 years, and 4,000IU for those aged 9 years and older. Blood levels should be monitored when someone is taking high doses of vitamin D.

Guidelines do not currently differentiate between supplementation with different forms of vitamin D .

  • breastfed
  • formula-fed and are having less than 500ml of infant formula a day, as infant formula is already fortified with vitamin D

Children aged 1 to 4 years old should be given a daily supplement containing 10 micrograms of vitamin D throughout the year.

You can buy vitamin D supplements or vitamin drops containing vitamin D at most pharmacies and supermarkets.

Women and children who qualify for the Healthy Start scheme can get free supplements containing vitamin D.

What Is Vitamin D2 And Is It Better Than Vitamin D3

There are two versions of vitamin D that can be found in supplements:

  • Vitamin D2, also referred to as ergocalciferol

  • Vitamin D3, also referred to as cholecalciferol

They are very similar molecules, and both are easily absorbed by the body.

There was a time when these two forms of vitamin D were thought to be equivalent and interchangeable. But now we know this is not entirely the case. Evidence shows that D2 is actually less effective at raising vitamin D levels, and has a shorter duration of action than its D3 counterpart. So while both can be used as a supplement, D3 seems to be slightly superior to vitamin D2.

Given that D3 seems to be a better option for supplementation, you might be wondering why providers prescribe vitamin D2 instead. The answer lies in the available formulations of the vitamin, which well explore next.
