When living with MTHFR mutations, it’s necessary when choosing supplements that they are easily absorbable, pure, and clean of unnecessary ingredients. Our Pure D3 is a medical grade vitamin D supplement which is highly absorbable and designed to be pure and free of toxic ingredients. A little goes a long way with this product, 1 single drop out of this D3 equals 1,000 units, and there are 1,500 drops in each bottle, making it very easy to find the dosing needed.

Vitamin D is essential for maintaining a healthy gut, and aids in repairing damaged tissues and cells within the body. As Vitamin D levels rise, it begins to function as a vitamin, meaning it starts turning on and off reactions and is critical to many necessary reactions. When living with MTHFR mutations, the immune system needs to be strong due to the buildup of toxins that distract the immune system from other threats. Vitamin D supports the immune system and having Vitamin D3 as an immune modulator, is essential for optimal gut health.

Remember: Vitamin D is a fat-soluble vitamin and needs to be taken with healthy fatty foods (avocados, almonds, olive oil). You’ll get a much better result when this vitamin is taken with fat.

Benefits of Vitamin D3:

  • Support and maintain a healthy immune system
  • Reduce inflammation 
  • Heals gut dysbiosis 
  • Repairs tissues and damages within the gut 
  • Reduce Auto-immunity 
  • Improves brain function 
  • Improves mood and sleep 
  • Supports calcium absorption and healthy bones 
  • Supports heart health and blood pressure regulation 
  • Supports dental health

Okay, let's talk vitamin D. If you are somebody that has MTHFR and you're taking vitamin D, this is probably one of my favorites. It is very, very highly absorbable and very pure. For anybody with MTHFR, those two things become the most important in deciding what kind of supplements that you want to take. So a medical grade vitamin D3. The other thing I like about this is one drop, one single drop, is 1,000 units. So you don't need a lot to go a very long way. It has 1,500 individual drops, so you know when you get this you're going to have it for a while. Again, a really clean, very pure, very good D3. If you want any scientific data on D3, geek out with me after this in the science note.

All right, science nerds, let's talk about vitamin D. So here's the thing. Vitamin D is super-important when it does its most basic function. So, when it's low, it does lots of gut health and repair types of jobs. When it gets a little bit higher, so from a lab standpoint anything from about 35, 40, it starts functioning as a vitamin, meaning it turns on and turns off reactions, and is a critical component to a lot of reactions. Above that number, vitamin D is an immune supporter, right? So as far as general health and immune strengthening, vitamin D plays a critical role in immune modulation. So anybody with MTHFR wants to always keep their immune strong and it's because it's easy to acquire toxins that can tie the immune up, and distract it, so having enough D3 on board becomes essential.

I like this product because it's medical-grade. It's very, very pure from a bioavailability standpoint, so how much of it actually gets in, it's very, very high concentration. Here in the office we've largely moved away from vitamin D as a pill, and we've gone more to these drops, because the absorbability looks to be much higher. That's to say oftentimes we'll do blood tests over here, the things that we were using previously, so vitamin D pills, they may work for some folks, but most people that have any kind of gut dysbiosis, they may not absorb D in the same fashion. So what I like is 1,000 units per drop so it's very easy to find the dosing that you need. And again I like the absorbability of this product.

One thing to note, science to science, is the fact that vitamin D is a fat-soluble vitamin, like A, E, and K. If you take a fat-soluble vitamin, but you don't take it with fat, chances are it's just gonna wind up in your poop. So, as far as whether you take vitamin D eating or not eating, fasting or non-fasting, fat-soluble vitamins always with fat. So if you want to have it with a handful of almonds, if you want to have it with a little bit of olive oil, with an avocado, but if you take your vitamin D with fat you'll get a much better result.
