My Vitamin D & K Combo Solved Bone Strength Issues

I have normally heard of tablets for only Vitamin D supplements. But in recent times, it has been suggested by the doctors to take the supplements having Vitamin D with Vitamin K, otherwise some health issue may arise specially when we are taking Vitamin D with calcium supplements. I bought this product for my mother as she has been suggested to take the calcium supplements to improvise the bone strength. After searching a lot, I found these tablets having Vitamin D + Vitamin K (all three types) and hence, I ordered these for her. And after taking these tablets for 10 days, she is really feeling better with her bone strength. She had made her mind of continuing with these tablets. A nice product for those who are searching for one solution for Vitamin D + Vitamin K supplement.

Vitamin Basics & Tips

Why Vitamin D Needs Vitamin K with Calcium Supplements

Vitamin D aids calcium absorption, but without Vitamin K, excess calcium can accumulate in blood vessels instead of bones. Vitamin K (especially K2) directs calcium to bones and teeth, reducing artery calcification risks. Doctors now recommend combining D3 with K2 for bone and cardiovascular health.

Types of Vitamin K: K1 vs. K2

Vitamin K1 (phylloquinone) is found in leafy greens and supports blood clotting. K2 (menaquinones, like MK-4 and MK-7) is in fermented foods and animal products, guiding calcium to bones. This product includes all three types (likely K1, MK-4, MK-7) for comprehensive benefits.

Bone Strength and Calcium Synergy

Calcium supplements alone can't improve bone density without Vitamin D (for absorption) and K2 (for calcium utilization). This combo prevents deficiencies linked to osteoporosis and fractures, as noted in the user's improved bone strength within 10 days.

Daily Vitamin D Needs and Sources

Adults need 600–800 IU of Vitamin D daily. Sunlight triggers skin production, but supplements help in low-sun regions. Pairing D3 with K2 ensures calcium is used effectively, avoiding risks like kidney stones or hardened arteries.

Common Questions About Vitamin D & K

Q: Can I take Vitamin D alone?
A: Short-term use is safe, but long-term high doses without K2 may increase cardiovascular risks.
Q: Which foods have Vitamin K2?
A: Natto, cheese, and egg yolks. Supplements simplify intake for consistent dosing.
