Everything You Need to Know About K2
Vitamin K2 is a powerful nutrient that hasn't been mainstream until recently, and it's becoming extremely popular due to the essential role it plays in the body. It can be found in fermented foods like sauerkraut, natto, and animal organs and is mainly taken to improve bone density.
A 2016 study that looked at 452 self-reportedly healthy adults concluded that 97% of them were K2 deficient.1 This has lead to many companies coming out with a K2 supplement, but the problem is many of them add unnecessary fillers or substances that are meant to keep everything stuck together, but actually end up being toxic.
After significant research, we put together this guide to ensure you buy a supplement that works and not one that either wastes your money, or worse, causes you harm.
Why is Vitamin K2 So Important?
Vitamin K2's most important function is guiding calcium away from your arteries and into your bones where it belongs. It also helps protect you from potential Vitamin D toxicity.
The absorption of vitamin D, whether from supplementation or from the sun, increases the production of calcium in your body. Calcium needs Vitamin K2 to tell it where to go or it can end up in your arteries, too much calcium could cause serious ramifications as it creates a blockage and blood can no longer circulate.
This is why Vitamin K2 and Vitamin D3 should be taken together. The combination will make for stronger bones and a reduced build-up of calcium in the blood pathways.
Important Distinctions
The Difference Between K1 and K2
Vitamin K1 comes from dark leafy vegetables and is mostly responsible for blood coagulation. It has no effect on calcium.
Vitamin K2 comes from fermented foods and animal organs, it directs calcium into the bones.
The Two types of K2 supplements
The two main forms of K2 are MK-4 and MK-7. They both perform similar functions but have key differences.
MK-4 supplements are derived synthetically and are less effective because they stay in the bloodstream for approximately 8 hours.
MK-7 supplements are derived from fermented foods and stay in the bloodstream for 24 hours or more.
What to Look for & Avoid in a Vitamin K2 Supplement
- Look For
- Clinically Tested K2 - MenaQ7® (MK-7) is the most bioavailable, longest-lasting, and most bioactive form of Vitamin K.
- Contains Vitamin D3 - D3 raises vitamin D levels more effectively than D2. Look for 3,000-5000 IU of D3.
- Paired with a Fatty Oil - Vitamin K2 is absorbed into the bloodstream most effectively when paired with fat (oil).
- Avoid
- Magnesium Stearate -This additive binds ingredients together. However, recent studies suggest magnesium stearate can be toxic.
- Microcrystalline Cellulose - Is derived from wood pulp that accumulates in our cells over time, causing side-effects like inflammation.
