Key Health Benefits

Vitamin D3 and K2 work together to maintain normal bones. Vitamin D contributes to the normal function of the immune system, while vitamin K contributes to normal blood clotting. This supplement provides 1,000 IU of D3 and 45 mcg of K2 (as MK-7) in a single daily capsule. Ideal for those looking to support their bone health and immunity, especially during months with limited sunlight. The formula is vegan, non-GMO, gluten-free, and kosher, making it suitable for a wide range of dietary preferences.

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) enhances calcium absorption in the gut. Vitamin K2 (menaquinone) activates osteocalcin, a protein that binds calcium to the bone matrix, and other proteins involved in calcium utilisation. The form of K2 in this product is MK-7, derived from natto, which has a longer half-life than MK-4, allowing for sustained support with once-daily dosage. By combining these nutrients, the supplement ensures that calcium is effectively directed to the bones, supporting overall bone maintenance.

Why Take Vitamin D3 and K2 Together?

Taking D3 and K2 together makes sense because they complement each other. Vitamin D3 helps your body absorb calcium from food, but without enough K2, that calcium may not be optimally utilised. K2 activates proteins that guide calcium to the bones, where it is needed most. This synergy helps maintain normal bone structure and strength. For many people, a combined supplement simplifies their routine while ensuring both nutrients are taken consistently.

What to Look For in a D3 + K2 Supplement

When choosing a D3 and K2 supplement, consider the form of K2. MK-7 is preferred for its sustained activity. The dosage ratio should provide enough K2 to support calcium direction – typically 45–100 mcg per 1,000–5,000 IU of D3. This product offers 45 mcg MK-7 with 1,000 IU D3, a balanced combination for daily maintenance.

Recommended Dosage

The suggested uses is one capsule daily, providing 1,000 IU (25 mcg) of vitamin D3 and 45 mcg of vitamin K2 (as MK-7). These dosages are appropriate for most adults for general maintenance. Since both vitamins are fat-soluble, taking the supplement with a meal containing fat may enhance absorption. Do not exceed the recommended serving unless advised by a health care professional. If you have specific health concerns, consult your doctor before uses.
