Vitamin K may not directly support our body’s immune system, but it does counteract the potentiality harmful effects of taking vitamin D by reducing its accumulation in soft tissues and blood vessels, where it can be harmful to health. So please don’t take a Vitamin D supplement that doesn’t also include Vitamin K.
K2 Synergy with Vitamin D3
The following quotes are from a 2021 webinar presentation by Dr Andrew Myers, Chief Scientific Officer at NutraGenetics and co-author of “Simplifying the COVID Puzzle”.
“Vitamin K2 improves the function of vitamin D. It activates proteins induced by vitamin D. This improves efficacy and may mitigate risks associated with high dose intake of vitamin D. While D supports calcium absorption from the gut into the bloodstream, it is K2 that regulates calcium metabolism in the body… K2 prevents calcium build-up in the vascular system, and brings it to our bones instead.”
“Unlike the function of pharmaceutical drugs, nutrients work together within all aspects of our biochemistry. The synergy between Vitamin D and Vitamin K2 is clear and should underscore the need to include both nutrients from a supplemental perspective whether promoting immune activity, cardiovascular function or bone health.”
