Vitamin D3 · K2 (MK-7) · Calcium · 60 capsules
Vitamin D3 helps your body absorb calcium. Vitamin K2 (MK-7) helps direct it to your bones. Together with calcium and BioPerine®, they support strong bones and a healthy heart.*

What it supports
Vitamin D3 helps your body absorb calcium and phosphorus, the minerals your bones are built from. Vitamin K2 then activates osteocalcin, a protein that helps bind that calcium into bone. Each capsule adds 210 mg of calcium to what you get from food.*
Vitamin K2 activates matrix Gla protein (MGP), which helps keep calcium from settling in soft tissues such as artery walls. That is why D3 and K2 work as a pair: D3 helps you absorb calcium, K2 helps send it to your bones. Together they support healthy, flexible arteries and normal circulation.*
Your body needs vitamin K to make prothrombin and other proteins involved in normal blood clotting. It is one of the oldest-known roles of this vitamin.*
Taking a blood thinner such as warfarin? Vitamin K can change how it works. Talk to your doctor before you start.
Vitamin D3 supports normal immune function and may help support a balanced mood, especially in the colder months when there is less sunlight to make it naturally.*

The science
Published studies on single ingredients, not on this formula. Read them as background on what goes inside, not as a promise of results.
Pooling randomized trials, researchers found vitamin K2 improved bone mineral density at the lower spine, especially when combined with vitamin D or calcium. No significant change was seen at the hip.
Healthy postmenopausal women taking MK-7 daily lost less bone density at the lower spine and hip neck than with placebo, with better bone-strength scores. No difference at the total hip.
This review describes how vitamin D works with both the innate and adaptive immune systems, and why the authors recommend keeping blood vitamin D at adequate levels. Trial results on supplementation are mixed.
Across trials in about 3,100 people with normal blood pressure, extra calcium lowered blood pressure slightly (about 1.4 mmHg). The effect was larger at intakes of 1,000 mg a day or more.
A review of vitamin K2 research on bone, cardiovascular and other calcium-related outcomes. The authors call the findings promising and ask for more trials.
Adults with an average age of 69 took a high dose of the MK-4 form. Arterial calcification still progressed; arterial stiffness improved only in those who started with low vitamin K status.
D3 helps your body absorb calcium. K2 activates the proteins that help bind that calcium into bone and keep it out of soft tissues like artery walls. One brings calcium in, the other helps send it where it belongs.*
Each bottle holds 60 capsules. At one capsule twice a day, that’s 30 days.
Vitamin K can interact with anticoagulants such as warfarin (Coumadin). If you take one, talk to your doctor before you start, and don’t change your vitamin K intake without their advice.
Each capsule provides 125 mcg (5,000 IU) of vitamin D3 and 210 mg of calcium. Add up what you get from every supplement and multivitamin, and check the total with your doctor or pharmacist.
Talk to your doctor or pharmacist before you start, especially if you take prescription medication or have a known medical condition. Not for use during pregnancy or while nursing without a physician’s advice.
Only microcrystalline cellulose and a vegetable (hypromellose) capsule. The formula is gluten-free, lactose-free and allergen-free, and manufactured in the USA.
