Should I supplement with Vitamin K2?

Vitamin K2 for better bone, brain and heart health is a must-have. Is it though? 

Dr. Greger from NutritionFacts.org says these claims are fraudulent at best. The research studies are conflicting and confusing. There’s no hard evidence that you can avoid hardened arteries or osteoporosis because of all the K2 pills you’re popping. 

• Vitamin K is important for blood clotting (German Koagulation, hence the name) 

• Babies are born with very little, so they are routinely given a one-time shot with the same. 

• Breast milk has some amount of Vitamin K. 

• The commonest forms of Vitamin K are K1- from plant sources; and K2 from animal products  

This begs the question: would non-meat eaters have a deficiency? 
No. Simply because the gut bacteria we possess can easily convert K1 into K2.
Also, fermented foods are a great source of K2. In reality, K1 and K2 have similar effects on the body. 

So, what should you do? 

• Ditch the pills, dip into the highest natural sources of Vitamin K 

• Dark green leafy vegetables 

• Cruciferous vegetables include cauliflower, cabbage, kale, garden cress, bok choy, broccoli, Brussels sprouts, and similar green leaf vegetables. 

Warning: if you are on a blood thinner or anti-coagulant medication; make sure you stay consistent with the amount of dark greens you consume. K2 can interfere with the effect of this medication; so work with your doctor to optimize levels according to the consumption of greens.
