Rapid weight loss takes
a hidden toll on your bones.

When mechanical load on the skeleton drops faster than bone can adapt, density follows. GLP-1 users eating less also absorb less calcium — compounding a risk that won't show up on a scale.

The bone density risk on GLP-1

You're losing weight.
Your bones don't see that as good news.

Bone density is maintained by mechanical stress — the load your skeleton carries. As you lose weight, that load decreases. Combined with lower calcium intake from eating less and impaired fat-soluble vitamin absorption, the conditions for bone density loss are all present on GLP-1.

Vitamin K2 (MK-7) is the critical co-factor that's missing from most calcium supplements. Without it, supplemental calcium can deposit in arteries rather than bone — the opposite of what you want.

The D3 + K2 + Calcium combination is the evidence-based approach to directing calcium to bone and away from cardiovascular tissue.

Full formula

Every ingredient.
Every dose. Every reason.

Calcium (as Carbonate)

500mg

The primary structural mineral of bone. Carbonate form has 40% elemental calcium — the highest of any calcium salt, making it highly efficient per capsule.

Vitamin D3 (Cholecalciferol)

20mcg (800IU)

Required for intestinal calcium absorption. Without adequate D3, most supplemental calcium passes through unabsorbed.

Vitamin K2 (MK-7)

90mcg

Activates osteocalcin — the protein that binds calcium to bone matrix. Critically, K2 also activates MGP, which prevents calcium from depositing in arterial walls.

Magnesium (as Oxide)

150mg

Bone is 60% calcium, 30% phosphorus, and 1% magnesium — but magnesium deficiency impairs PTH signalling, reducing bone mineralisation regardless of calcium intake.

Common questions

Everything you want to know.

Should I be worried about bone density on GLP-1?

It's worth monitoring. The risk is real and often overlooked. A DEXA scan at 12–18 months into GLP-1 use gives you a baseline. Proactive supplementation is the sensible response.

Why K2 and not K1?

K1 is mainly used for blood clotting. K2 (specifically MK-7) is the isoform that activates bone-specific proteins and has the longest half-life in the body.

Can I take this with my GLP-1?

Yes — no known interactions.

What if it doesn't work?
