This **Vitamin D3** and **Vitamin K2** pairing delivers 2,000 IU of D3 with 90 mcg of K2 at everyday maintenance doses for ongoing bone and cardiovascular upkeep, with both nutrients sitting inside their clinical ranges. The 2,000 IU of D3 (50 mcg) is a comfortable daily amount that keeps your blood levels topped up rather than correcting a deficiency, and it stays well under the 4,000 IU upper limit, so this is built for steady, long-term use.

The value here is the pairing itself: D3 drives calcium absorption while K2 helps direct that calcium into your bones instead of your arteries. That synergy is real in this product because both vitamins land at effective doses. Your K2 is the MK-7 form, which stays active in your body long enough that a single daily softgel does the job without splitting doses, and the olive oil softgel base helps both fat-soluble vitamins absorb.

At 90 mcg, the K2 sits right at the bottom of the studied 90 to 200 mcg range, which is fine for maintenance but lighter than you'd want if your main goal is moving arterial calcium specifically. One genuine caution: if you take warfarin or another blood thinner, vitamin K can interfere with how that medication works, so check with your doctor before starting this.
