Supports bone health and calcium utilization.
K1 is mostly for blood clotting and comes from leafy greens. K2 is for calcium placement and comes from fermented foods or animal products.
It's a very good idea. Vitamin D helps you absorb calcium, and K2 helps direct that calcium to your bones instead of your arteries.
MK-7 is generally better. It stays active in your body for much longer, so you can take it once a day.

The compound effect of consistent dosing.
Check the cautions section if you have a pre-existing condition.
Some ingredients you feel. Others just work in the background.
It's tough unless you eat natto (fermented soybeans) regularly. Cheeses and egg yolks have some, but often not enough.
The evidence is promising. By keeping calcium out of artery walls, it may help maintain flexibility and blood flow over the long term.
Take it with a meal that has some fat in it. K2 is fat-soluble, so this helps your body absorb it.
Most research uses 180.0g daily. Below 90.0g, you're probably wasting money. Above 400.0g, no extra benefit. The curve plateaus. Safe upper limit ~ 1000.0g.
Activates proteins like osteocalcin and matrix GLA protein (MGP), which are involved in bone mineralization and calcium regulation.
There's reasonable evidence supporting Vitamin K2's role in bone health and calcium metabolism, particularly in specific populations. Studies suggest benefits, but the effects can be subtle and require consistent intake over time. It's not a dramatic effect, but a worthwhile contribution, especially when paired with Vitamin D3.
Primarily from bacterial fermentation. The richest source by far is Natto, a Japanese dish of fermented soybeans.
