Vitamin D (Cholecalciferol) | D2 vs D3 | Vitamin D Deficiency

We mentioned that vitamin D2 doesnt affect your overall levels of vitamin D as much as D3. But that doesnt always mean vitamin D3 is the better form. While D3 does appear to be more effective than D2 in raising blood serum levels of vitamin D, Hunnes underscores that the best supplement is the one you can stick to taking.

And for most vegans and vegetarians , that makes D2 a more practical method for preventing deficiency. In fact, once either D2 or D3 is converted by your body into the active form of vitamin D, they both benefit your body in the same way.

While D3 is found in some animal products, D2 is found in plant products such as some mushrooms, some plants, and yeast. Vitamin D2 supplements are made from fungus and yeast, not sheeps wool.

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!

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.

Which Form Of Vitamin D Is More Beneficial

Difference Between Vitamin D and Vitamin D3

Form matters when it comes to supplementing with vitamin D. According to Bannan, D3 is the body’s preferred form of vitamin D because it’s produced in the body naturally and is more efficient at increasing blood levels. In fact, D3 is 87% more potent and effective at raising and maintaining serum 25D levels than D2. And since 25D levels are your status biomarker, that’s a majorly impactful difference.

D2 is significantly less effective because of the structural differences that affect the way the body metabolizes the vitamin. Vitamin D2 also has increased catabolism and its metabolites have weaker binding affinity to the vitamin-D-binding protein .

“These two nutrients are not biologically equivalent or interchangeable,” Ashley Jordan Ferira, Ph.D., RDN, mbg’s vice president of scientific affairs, previously wrote for mindbodygreen when dissecting D3’s scientifically proven superiority over D2. “One is effective , and the other is way less effective . Any suggestion that vitamin D3 and D2 are both good options falls into the ‘bad science’ bucket.”

When it comes to bioactivity, vitamin D3 has been shown to raise free 25D levelsan up-and-coming biomarker that may be more sensitive than total 25Dwith greater efficacy than D2. “This is yet one more compelling piece of evidence cementing the superior bioefficacy of D3 over D2,” Ferira concludes.

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.

Is Vitamin D Or D3 More Effective

Vita Sciences Maxasorb Vitamin D3 Cream Initial Impressions Review ...

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. Calcifediol is the precursor to calcitriol, the ultimate active metabolite of vitamins D and D3.

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.

Are Vitamin D And Vitamin D3 The Same Thing

This is a tricky question as, technically, there is no such thing as singular Vitamin D. Vitamin D actually refers to a grouping of compounds which all have similar effects within the body, known as Vitamins D1-5. If youre looking at the nutritional lists on supplements, youll see that the two most common options for Vitamin D are D2 and D3, and D2 is commonly referred to as Vitamin D. So, for the purposes of clarity – whenever we mention Vitamin D in this guide, we are referring to D2. Well always call D3, D3 .

Vitamins D and D3 are both fat soluble vitamins which play roles in keeping our immune system healthy and helping with calcium absorption. Vitamin D is only available from plant sources, such as mushrooms, whilst D3 is usually sourced from animal products.

We can also obtain all of the Vitamin D3 we require via sunlight, but throughout the winter this is harder to achieve with shorter days and more clouds. Even during the summer, it can be difficult to absorb enough through our skin due to the need to protect ourselves against the risk of skin cancer, either by covering up or applying copious amounts of sunscreen.

Where Do We Get Vitamin D

The main source of vitamin D is sunshine. It is produced by the body through sunlight on the skin. However, many people, especially those living in colder climates, are deficient and may require additional supplementation.

Through the winter months in the UK, many of us dont get adequate levels through sunlight exposure so supplementation may be required.

Vitamin D can also be obtained through diet, eating foods that have a high Vitamin D content such as:

  • Oily fish trout, salmon, sardines, herring, and mackerel

Melanin is a pigment in the skin that makes it darker, so black people have high amounts of melanin, giving their skin its characteristic look.

So when it comes to supporting your immune health, vitamin D3 is the best option.
