Broadly, what’s the function of vitamin K?

First, it’s important to know that there are two types of Vitamin K: K1 and K2. K1 is easily taken into our diet from green leafy vegetables like spinach and broccoli.

How does K2 help our bones?

Not all of the calcium we eat gets absorbed without the help of a protein called osteocalcin. And K2 supports osteocalcin.

Are we getting enough K2?

The caveat here is that K2 is produced by bacteria, which we used to get a lot more of as a population when we would ferment foods to preserve them. But now, because we have refrigerators, we eat more fresh food—that can impact our K2 intakes.*

Why did you choose to make K2VITAL in a lab instead of finding a source in nature?

We wanted to make something that was identical to what you’d get from food. It sounds counterintuitive, but the only way of doing that was through organic synthesis. That’s because when you start with a natural source, it still has to go through a lot of changes to get put in a pill. For K2VITAL, we actually start with plant sources and extracts, and then we use synthesis to ensure that we keep the end result entirely identical to the start.*

Anything else that’s unique about your manufacturing?

All K2 vitamins are not the same. K2 is fat-soluble, and when you mix fat-soluble vitamins with minerals (especially calcium and magnesium), you risk rapid deterioration because you introduce alkalinity. But we’ve developed a patented double-coated capsulation process called the delta formulation, designed to circumvent this.
