Is Vitamin D2 the Same as Vitamin D3?: Breaking Down The Differences
It sounds like a riddle that even the Sphinx couldn’t crack: Is vitamin D2 the same as vitamin D3?
And just what exactly is vitamin D anyway, and why should we care?
How does it work in our bodies?
With so many questions and a gazillion supplements and multivitamins on the market, it can feel like you’re lost in a vitamin alphabet soup! How can we make sense of all these labels and pick out the best supplements for our bodies?
Don’t worry! In this post, we’re going on a vitamin D deep dive. We’re going to break down all the jargon, answer all your burning questions, and help you navigate the world of supplements like a pro.
Let’s get started!
Let’s Unravel the Vitamin D Mystery!
Not many are aware that Vitamin D is not just one single entity but a family of nutrients. Yep, you heard that right! It includes two primary forms: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol).
Let’s take a closer look.
D2: The Plant-Based Powerhouse
Vitamin D2, also known as ergocalciferol, is the undercover agent of the vitamin D world. It’s a plant-derived form, found in certain mushrooms and foods fortified with vitamin D, like some cereals and orange juice. The reason why vitamin D2 is called ergocalciferol is because of its molecular structure, which is ergosterol that’s been zapped by UV radiation that comes from the sun. Cool, right?
D3: The Sun Seeker
Moving onto vitamin D3, or cholecalciferol, this one is a sun-lover. It’s produced when your skin gets a sun-kissed hello from UV-B rays. Your skin contains a compound called 7-dehydrocholesterol, which is converted into vitamin D3 when it comes in contact with UV-B rays. In fact, vitamin D3, cholecalciferol, gets its name from its molecular structure, which is 7-dehydrocholesterol that, like D2, has been hit by UV radiation.
But, we’re not telling you to ditch sunscreen and go sunbathing just yet! Skin protection is still crucial, and you can always get your vitamin D3 fix from other sources. For example, we can also get it from animal-based foods, like fatty fish, cheese, and egg yolks.
The Making, Absorption, and Bioavailability of D2 and D3
Our liver and kidneys play a big role in converting inactive vitamins D2 and D3 into their active forms, which can then be absorbed by the body.
But, here’s where things get interesting! Both vitamins follow different metabolic pathways once they’re converted to their active forms. Research shows that vitamin D2 has a shorter half-life and is less effective in raising blood levels of vitamin D than vitamin D3.
Also, vitamin D2 has a lower bioavailability rate compared to D3. Bioavailability means how much of the nutrient gets absorbed by your body and stays there for it to use. One study found that D3 causes a higher and longer-lasting increase of up to 87%, in levels of 25(OH)D than D2 – which is a pretty significant difference! This means D3 is more effective in raising and maintaining vitamin D levels in the body.
So while both D2 and D3 are important, if your body had to pick a favorite, it’s likely to go for D3!
The Awesome Perks of Vitamin D
It’s clear that having a good amount of vitamin D is a big deal, but why exactly is that so? Let’s dive into the fantastic health benefits this sunshine vitamin has in store for us. Ready? Let’s go!
1. Boosts Bone Health
Vitamin D plays a significant role in the absorption of calcium and phosphorus, which are the key players in maintaining our bone health. According to a study, a deficiency of this nutrient can lead to bone diseases like osteomalacia in adults or rickets in children. So, if you want to keep your bones healthy and strong, make sure you’re getting enough Vitamin D!
2. Supports Immune System
It turns out that vitamin D is also a big fan of your immune system! Research has shown that vitamin D can help enhance the function of immune cells, which protect your body against pathogens. A study even suggests that vitamin D deficiency is linked with increased susceptibility to infections. So, a little sunshine or D3 supplement can help keep those sniffles at bay!
3. Might Improve Mental Health
Last but not least, getting enough vitamin D might just make you happier! There’s a growing body of research suggesting a link between low levels of vitamin D and depression. So, maintaining adequate levels of this vitamin might be good for your mood! Remember, your mental health is just as important as your physical health. So, don’t forget to take your vitamin D!
How Much Vitamin D3 Do You Need Daily, and What Happens If You Go Overboard?
Okay, let’s talk numbers!
According to the Institute of Medicine, all kids and adults need about 20 mcg per day. But remember, these are just guidelines, and individual needs might vary.
Now, what happens if you get too much of a good thing? Vitamin D toxicity, or hypervitaminosis D, isn’t common but can happen if you take an excess amount over an extended period.
- stomach ulcers
- pancreatitis (inflammation of the pancreas)
- frequent urination
- kidney failure
- and abnormal heart rhythms.
That’s where a multivitamin like First Day comes in. They make sure you get just the right amount of Vitamin D3, without the worry of going overboard. It’s a balancing act, and they’ve done the hard work for you.
