Is vitamin d and d3 the same thing?

If you’re reading this article, then congratulations on taking your first steps towards better health! You’ve probably heard about vitamin D and how it’s essential for healthy bones, teeth, and immune functions. But have you ever wondered what the difference is between vitamin D and vitamin D3? Are they really the same thing or completely different entities? Well, in this article we’ll dive deep into all things shiny (sorry couldn’t help myself there)- I meant “vitamin-D” related!

What is Vitamin D?

Let us start at the beginning of our story: with an introduction to what actually is Vitamin D…

Vitamin-D happens to be a fat-soluble nutrient that helps your body absorb calcium from food or supplements. It assists in maintaining a balance between minerals like phosphorus, magnesium etcetera thereby making sure that your nervous system {string-less puppet} performs seamlessly. This vital hormone does not only support skeletal growth but also helps muscles move better & protects against certain diseases while supporting brain function.

There are two types of Vitamin-D that exist naturally – ergocalciferol (D2) synthesized by plants from ultraviolet irradiation hitting cells surface; while cholecalciferol (D3) produced when sunlight strikes upon skin cells – further metabolized by liver & kidneys- Yep sounds like rocket science right?!

So…what makes it so special again?

Okay now let me give whatever little knowledge I remember soaking up during those chemistry lectures… some may argue even less than little but I digress:
Despite being called a ‘vitamin’, it isn’t an essential dietary component as can be synthesised endogenously on skin exposure {contraction mark}. In addition to sunshine spreading warmth over much-needed cold shivers throughout winters – sunrays release unsightly past acne scars& sweet sweet serotonin stored within multiple layers of skin.
But don’t get too carried away; limited sun exposure can be beneficial & suffice for daily D3 synthesis, however over-exposure of ultraviolet rays does lead to skin cancer – You must have heard the phrase- Too much of everything is bad?

Why There is a Debate About Vitamin D and D3 Not Being The Same Thing

Confused about whether vitamin-D and -D3 are interchangeable or completely different beasts altogether? Have no Fear! So are several researchers who’ve been partaking in ‘vitamin-D&D’ discussions on social media platforms.

Well, the answer isn’t as simple as just disqualifying one as imposters or claiming them to be similar enough in properties that they’re practically twinsies (better believe we went there). Here’s why: when you obtain natural sources of vitamin D from sunlight {potentially harmful damages}, food & supplements, it comes in two forms – ergocalciferol (D2) and cholecalciferol(D3). Though sharing structural similarities they also carry distinct differences for e.g : which organ produces it , how bioavailable it is…yadda yadda

Let’s dive deeper (Metaphorically please)

Chemistry Time!

Now instead of rapping like Megan thee Stallion let us break down some science {looks at camera while adjusting glasses}:
Vitamin-D exists more than five forms each characterised by molecular structure :
Ergosterol OR Provitamin-D2
Synthesized by plants -made into non-toxic topical creams/supplements/showcased frequently by vegans.
Cholecalciferol OR Previtamin–D(5)
Produced mostly through cutaneous excitation/ Fish liver-Oil Supplements /Sun expsoure-displays higher affinity towards proteins responsible for carrying withing your blood streams aka “VD binding protein”
Calcidiol OR 25-hydroxycholecalciferol (the storage form of vitamin D)
Engages liver enzymes to create this intermediate metabolite that acts as a warehouse for Vitamin-D ; So it’s possible to measure natural concentration levels in blood samples (peri) )
Calcitriol OR active Vitamin-D hormone {Don’t go on the name its not an action thriller -not impressive }
It is able/allowed by kidney organs only to activate once calcidiol is converted when your body needs extra calcium Phosphate ;- helpful against Inflammation;
Paricaltrio Or Synthetic derivatives
On their way of approval but aims towards matching structures& binding properties

The difference between Vitamin D and D3

The primary differing element between regular vitamin-D and cholecalciferol (Vitamin-D3), synthetic ergocalciferol arises in preparation; however, these slight deviations can result in significant discrepancies sometimes:

  1. Origins
    One primary difference among various others includes where & how they come into existence:
  2. Ergocalciferol commonly found in plants
  3. Cholecalciferol more often present inside animals people derive from food or sunlits exposure.

  4. Effectiveness level
    Yes, there’s some science behind such statements! Vitamin d3 has greater activeness than Vitd since It reaches-the actual spots including those responsible for VDbinding protein without going through extensive conversion process makes it easier for organ functionality .

Ultimately professionals have decided that both are important components which play roles at specific moments regulating metabolism balance factors interacting body functions – so now we know they aren’t twinsies!

Why take supplements containing vitamin D3 over regular Vitamin-D?

If you’re still confused about whether taking supplements containing one over the other benefits significantly need I remind you of our dear friends Bioavailability & affinity? To better understand this concept let’s look at some numbers:

For every Vitamin D supplement, you take orally (no that doesn’t mean yanking it out of your mouth), only 60 to 80% gets absorbed into the bloodstream. And after that small portion drives through blood vessels, over to almost all cells& systems of our body- Several proteins contend for its interaction like loosely bound DBP or tightly attached Albumin providing movement across cell membranes transporting cargo.

But wait— It Gets even more complicated!

Beyond Bioavailability VitD and VD3 tend to interact with Different Proteins differently depending on situations as well; therefore, the time required varies by each type’s uptake rate ,efficacy/affinity for active forms – which can significantly affect patience levels if no improvements are observed in weeks. long sigh Sometimes a little workaround is necessary 😉(please refer to next point below)

Do I Need Both Types of vitamin D in my diet?

In short yes but also not really… Oh wow how clarifying was THAT?! But hear us out:

Research suggests Cholecalciferol [achieved best via sunlight☀️) has superior bioavailability & higher metabolic response rates than Ergocalciferol; Yet in certain circumstances when sufficient calcium intake alongside low Vitd-binding protein availability -ergocalciferol exhibits superiority! {Equally worth mentioning optimal amounts are still being determined }

Therefore some health practitioners recommend taking both types at once cause sometimes ain’t nobody got the patience- expenses too high etcetera BUT others argue there isn’t enough evidence to suggest supplementation provides added benefits so check with your medical practitioner first ,pretty please!.

Look on bright? side If supplements turn not suitable —taking things back-to-basics means we get sunshine(free variable exposure available ) whole foods containing rich minerals end up spending less especially compared expensive ray-emitting chamber kind-thats… quite something huh (personally wouldn’t know just saying)- Steer clear from ones made of seashells though unless you are an ancient sea creature

Conclusion

In conclusion, we’ve learned that vitamin D and Vitamin D3 aren’t exactly the same thing but do work together in concert to make our bodies tick. While Cholecalciferol is better absorbed than ergocalciferol ingesting too much of either one can have unwanted consequences since toxicity issues exist due to their fat-soluble nature. With so many supplements on the market & advice being bombarded constantly it’s essential always to check with your doctor or medical practitioner before taking any drastic ranges- Also if anyone knows how Myrtle managed writing a potion book about each herb while teaching Herbology lemme know!
