Is Vitamin D And Vitamin D3 The Same

Should You Take Vitamin D2 Or Vitamin D3

Vitamin D2 vs. D3: VERY DIFFERENT

In your diet, the most commonly found members are vitamin D2 and D3 . While both types help you meet your vitamin D requirements, they differ in a few important ways. Research even suggests that vitamin D2 is less effective than vitamin D3 at raising blood levels of vitamin D. This article sums up the main differences between vitamin D2 and D3.

What Happens When You Take Your Daily Vitamin D3

When you take a Vitamin D supplement, the vitamin passes from your bloodstream into your liver.

From here, it goes to the kidneys where it turns into calcitriol.

It is then released back into your bloodstream and can now enter your bodys cells where it attaches to Vitamin D receptors.

At this point, it can get to work regulating the minerals calcium and phosphorous. Clever stuff!

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.

Common Uses Of Vitamin D3

Vitamin D3 helps support immune health as well as various other important functions in the body. As part of your daily health routine, regular D3 supplementation can help protect you against seasonal and environmental threats. Additionally, by helping support immune cell function and promoting healthy immune responses, D3 can help reduce common oxidative stress.

The role that vitamin D3 plays in supporting bone strength allows it to be an important addition to a daily routine for those looking to maintain strong, healthy bones. As part of a healthy lifestyle, D3 can help achieve optimal peak bone mass to support a healthy musculoskeletal structure at any age.

Finally, vitamin D3 can be used to support heart health. A lack of vitamin D3 in the diet can be associated with high cholesterol, so with regular supplementation, you can promote healthy cholesterol levels to support heart and arterial health.

Coverage And Cost Comparison Of Vitamin D Vs D3

Vitamin D2 in prescription form is commonly covered by most commercial and Medicare insurance plans. The over-the-counter formulations are typically not covered by commercial or Medicare insurance plans. The price can vary greatly depending on dosage. The average cost of the 50,000 IU dose for 12 weeks of therapy is $47.99. With a coupon from SingleCare, this price drops to as low as $11.

Vitamin D3 is over-the-counter, and therefore is typically not covered by insurance plans. The price varies depending on dose. D3 can cost as $40 but if your doctor prescribes the medication you can get it for as low as $20 with a SingleCare discount coupon.

Drug Interaction With Vitamin D2 Vs D3

Both forms of Vitamin D are metabolized by the liver, therefore potential interactions with other drugs are similar for D2 and D3. Vitamin D can increase your levels of aluminum when regularly taken with aluminum hydroxide, a common antacid. Furthermore, thiazide diuretics could dangerously increase the levels of calcium when mixed with Vitamin D supplements.

As always, it’s important to consult a health practitioner for proper medical advice before taking any prescription or supplements ,especially if you have certain health conditions.

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 Vitamin D And Calcium

Vitamin D and calcium are nutrients that sustain healthy bones. They are also needed for:

  • Muscle movement

  • Absorption of calcium and phosphorous

  • Immune system responses

  • Signaling between cells

  • Hormonal secretion

  • Blood vessel flow

Without enough vitamin D or calcium, your parathyroid glands compensate by producing too much of their hormone, a condition called hyperparathyroidism. That can lead to bone weakening and increased fracture risk. Other problems from calcium and vitamin D deficiencies include:

  • Skeletal deformities in children ages 6-24 months

  • Muscle weakness in children and the elderly

Given the crucial role of both nutrients in bone health, The Endocrine Society and the Institute of Medicine recommend certain consumption levels based on age and health. They have not yet found, however, that taking vitamin D provides cardiovascular protection.

However, when vitamin D is absorbed in the body from through the skin, it is not possible for you to overdose. You see, the skin simply stops absorbing the vitamins when there is enough stored in the body. After that, you are just getting exposure to the sun.

When it comes to supplementation, vitamin D supplements are effective. However, the body doesnt absorb as many nutrients from the supplement as it does from the sun.

Whats The Difference Between Vitamin D And Vitamin D3

There are two possible forms of vitamin D in the human body: vitamin D2 and vitamin D3. Both D2 and D3 are simply called âvitamin D,â so thereâs no meaningful difference between vitamin D3 and just vitamin D.

That being said, it can be worth understanding how vitamin D2 and D3 specifically are different from each otherâso hereâs a quick rundown:

  • Vitamin D3 is the form of vitamin D the human body makes when sunlight strikes the skin. The body canât manufacture vitamin D2.

  • Vitamin D3 is found in animal sources of foods, like fatty fish and fish oil, liver, organ meats, and egg yolks.

  • Vitamin D2 primarily comes from plant sources , and forms when certain kinds of plants are exposed to ultraviolet light from the sun.

  • Vitamin D2 is also less expensive to produce, so it is the form most commonly used to fortify foods, like milk, cereal products, and orange juice.

Do I Have A Vitamin D Deficiency

Vitamin D2 vs D3 What’s the difference? #Shorts

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.

The Basics Of Vitamin D

Vitamin D is a unique type of vitamin because it actually acts more like a steroid hormone than a dietary aid and is not readily available in most foods like other vitamins often are because of this, its estimated that nearly 75 percent of people have some kind of deficiency.

Rather, vitamin D is sourced primarily from the sun, which is why its often referred to as the sunshine vitamin. When the skin absorbs sunlight, it synthesizes the UVB rays into vitamin D.

Though you should always limit long exposure to the sun, getting adequate amounts of rays is the first step in ensuring your body has good stores, which is important since vitamin D has a tremendous effect on mood and, over time, can help to ease symptoms of depression. Its also a type of fat-soluble vitamin that plays a major role in the way the body absorbs other nutrients.

But not everywhere in the world is as sunny as California or Florida, which limits access, and because the synthesization process varies from person to person, not everyone has the same capability to intake the proper amounts needed for optimal well-being. This is where supplements come into play.

It Boosts Weight Loss

Raising Vitamin D levels are associated with boosting weight loss. Studies show that those taking D supplements were able to lose more weight than those who took placebo supplementation.

Obese people can also benefit in taking more Vitamin D in preventing the risk of developing heart diseases, which is common among those who are overweight.
