What's inside
A clear, evidence-based plan you can act on and take to your physician.

Feed the matrix. The protein, calcium, and magnesium your bones are actually built from.
3
Get the vitamin duo right. How vitamin D and K2 (MK-7) decide where your calcium goes.
4
Remove the bone thieves. The habits and medications quietly weakening bone.
5
Prevent the fall and know your options. Fall-proofing, DEXA and FRAX, and when medication helps.

Frequently asked questions
Is this medical advice?
No. This protocol is for education only. It is built to help you and your physician work together, not to replace a clinician who knows your history. Never start, stop, or change a medication or supplement on your own.
Can I really improve my bones, or only slow the loss?
Both are realistic goals. Loading your skeleton and getting the nutrition right slows loss for nearly everyone, and can improve strength and density, especially when you start early and stay consistent. When risk is high, medication adds further protection.
I take a blood thinner. Can I take vitamin K2?
Not without your doctor. If you are on warfarin (Coumadin), vitamin K and K2 can reduce how well it works. Talk to your prescriber first. Everything else in the protocol still applies to you.
Do I need to give my email?
Yes. Enter your email and I'll send you the PDF right away, along with a weekly research review. It's free, and you can unsubscribe anytime.
