Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 stimulates the production of calcium-binding proteins in the gut, enhancing calcium absorption. Vitamin K2 activates matrix GLA protein (MGP) and osteocalcin. MGP helps inhibit calcium deposition in blood vessels, while osteocalcin helps bind calcium to the bone matrix. This coordinated action helps maintain the body’s calcium balance and supports bone density.*

Many people supplement with vitamin D3 alone, but without enough K2, the calcium you absorb may not be optimally utilised. Adding K2 ensures that calcium is directed to the skeleton rather than accumulating in arteries. Bronson’s formula provides an ideal ratio of D3 to K2, with a full 120 mcg of MK-7 to match the high 10,000 IU D3 dose.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 are a synergistic duo that work together to support your body’s calcium metabolism. While vitamin D3 helps your body absorb calcium from the digestive tract, vitamin K2 helps direct that calcium to the bones and teeth where it’s needed most—and away from soft tissues like arteries. Without adequate K2, calcium absorbed thanks to D3 may end up in the wrong places. This powerful combination is essential for maintaining strong bones and a healthy cardiovascular system.*

What to Look for in a D3 + K2 Supplement

• Form of K2: Look for MK-7 (menaquinone-7) rather than MK-4. MK-7 has a longer half-life and requires fewer daily doses.
• Dosage Ratio: A higher D3 dose (like 10,000 IU) should be paired with an adequate amount of K2 (at least 100 mcg MK-7) to support proper calcium routing.
• Quality and Purity: Choose brands that follow GMP (Good Manufacturing Practices) and undergo third-party testing. Bronson’s formula is produced in a GMP registered facility in New York.
• Trusted Brand: Bronson has been a name in vitamins since 1960, consistently recommended by health care professionals for quality and reliability.

Bronson’s Extra Strength K2 + D3 meets all these criteria, offering a potent, well-balanced, and rigorously tested supplement.

Recommended Dosage

As a dietary supplement, take one (1) easy-to-swallow capsule daily with a meal. Each bottle contains 120 capsules, providing a four-month supply. Do not exceed recommended dosage unless directed by a health care professional. Keep out of reach of children.

Frequently Asked Questions

Can I take vitamin D3 and K2 together? Absolutely. In fact, taking them together optimises the benefits of both. D3 increases calcium absorption, and K2 ensures that calcium is properly distributed.

What is the best time to take this supplement? Take with a meal containing fat (such as breakfast or dinner) to enhance absorption of fat-soluble vitamins D3 and K2.

Are there any side effects? Most people tolerate this supplement well. However, very high doses of vitamin D3 may cause hypercalcaemia. Consult your health care provider before starting any new supplement, especially if you are taking blood thinners like warfarin (due to vitamin K interaction).

Can I take this if I’m vegan? Vitamin D3 in this formula is derived from lanolin (sheep’s wool), so it is not vegan. However, the K2 (MK-7) is from natto, which is plant-based. Individuals following a vegan diet may wish to look for a vegan D3 from lichen.
