Why Vitamin K2 + D3 Extra Strength – 10,000 IU D3 + 120 mcg K... works
A targeted blend of research-studied ingredients, formulated at the doses studies actually used — not the dusted-on amounts found in cheaper formulas. Every milligram is printed on the label so you know exactly what you are taking.
Simple daily routine
Take one capsule daily with a meal that contains healthy fats—such as avocado, olive oil, nuts, or fatty fish—to enhance absorption of these fat-soluble vitamins. Consistency is key: aim to take your capsule at the same time each day to build a reliable routine. If you're new to high-dose D3 or have existing health conditions, consult your healthcare provider before starting. Store in a cool, dry place away from direct sunlight.

Real Reviews From Supplement World Customers
"I've tried at least six D3 products. This is the first with meaningful K2 MK-7 at a dose that actually matches the research. No fillers, no soy, just what I need in one capsule."
"My naturopath specifically recommended a K2/D3 combo with at least 100 mcg MK-7. This formula hits that mark and the 10,000 IU D3 aligns with my bloodwork needs. Very happy with the quality."
"I was taking D3 and K2 separately and constantly running out at different times. This streamlined everything into one daily capsule. The MK-7 form is a nice touch—more bioavailable than cheaper versions."
"The dose is higher than most brands and the K2 is the right form. I dock one star for price, but I'd rather pay more for quality ingredients that are actually research-backed."
"I needed a high-dose D3 with K2 to support my bones as I age. This checks every box: MK-7, no GMOs, gluten-free, and a strength my wellness routine approved. Four months in and very satisfied."
"I'm particular about what I put in my body. This formula is free of the allergens I avoid and the ingredient list is refreshingly short. The capsules are easy to swallow and I feel good about taking them daily."
"D3 alone wasn't enough—I needed K2 to help direct calcium properly. This product pairs them at potent doses and I love that it's just one capsule a day. Makes staying consistent so much easier."
"The ingredient quality is excellent and the MK-7 form is what I wanted. The capsules are a bit big for me, but I can still swallow them with water. Overall very pleased with the results after two months."
