“Vitamin K2 should always be taken with vitamin D3,” said Webber. “Vitamin D3 and vitamin K2 we call the perfect pair and that's because vitamin K2 actually makes vitamin D3 work more efficiently and more safely in the body. Higher doses of vitamin D3 can actually be detrimental, but vitamin K2 can kind of prevent those side effects from happening by shuttling that excess calcium to the right places. Not just vitamin D3, does it play nicely, [but also] with bone health, immune health, sports nutrition, women's health—all of those categories. You can also build those formulations out even further by adding things like CoQ10 and omega-3 for heart health, and adding some minerals in for bone health to make a more well-rounded, differentiated supplement. So definitely K2 plays with a lot of other vitamins very well.”
Webber added that while it still flies largely under the radar, more consumers are becoming familiar with K2.
“We have noticed a huge spike in popularity and vitamin K2 lately. I think a lot of what's driving that is there is new immune research, which is so timely on vitamin K2. So I think that getting out into the news, [which] is really supporting the growth. On top of that, since vitamin K2 should always be taken with vitamin D3, people are just taking more vitamin D3 higher doses than ever. So I think that K2 is kind of being pulled along with that trend as well,” she said.
