Vitamin K2 acts as the body’s traffic controller for calcium—making sure it goes where it’s needed (your bones) and stays away from where it’s not (your arteries).
Considering Supplements?

If you’re thinking about supplementing with K2, here’s what you need to know:
There are two common forms: MK-4 and MK-7.
- MK-4 absorbs quickly but leaves the body faster.
- MK-7 lasts longer in your system and only needs to be taken once per day.
You’ll often see K2 supplements paired with vitamin D3—because these two work together. Be sure to choose D3, not D2, since it’s more effective for your body.
The typical dose for MK-7 ranges from 90 to 200 micrograms per day, depending on your needs.
But remember: real food is still the best source of nutrients. A balanced, nutrient-rich diet beats any supplement.
To recap:

- Vitamin K2 helps prevent calcium buildup in arteries and supports bone health.
- It’s found in fermented and animal foods like natto, cheese, butter, liver, and egg yolks.
- Vitamin D is key for absorbing calcium into bones—but vitamin K2 helps keep it out of your arteries.
- You can supplement with MK-4 or MK-7, but diet is your best long-term strategy.
