🦴 Bones and Teeth: Calcium, Phosphorus and Vitamins for Bone Health
Bones are not "rocks" but living tissue that constantly renews
Bones and teeth seem "dead," but they're not. They are living bone tissue that needs calcium, phosphorus, vitamins D3 and K2. Let's look at how it all works together.
How bones build
Bone tissue constantly renews: old cells are replaced by new ones. This needs a steady supply of "building materials."
- Bones are alive.
- Constant renewal.
- Need materials.
- Density matters.
Calcium
Calcium is the main "building block" of bones and teeth. It gives them strength.
- Bone strength.
- Tooth strength.
- "Building block."
- Needed all life.
Phosphorus
Phosphorus works with calcium, forming part of bone tissue. Balance matters — excess phosphorus interferes with calcium.
- Together with calcium.
- Bone composition.
- Balance matters.
- Excess harms.
Vitamin D3
Vitamin D3 helps the body absorb calcium. Without it, calcium "doesn't stay" in bones.
- Calcium absorption.
- Useless without it.
- Sun and food.
- Common deficiency.
Vitamin K2
Vitamin K2 "directs" calcium into bones, not into vessels. It works together with D3.
- Directs calcium.
- Into bones, not vessels.
- Pair with D3.
- Important for absorption.
Food sources
| Substance | Food | Comment |
|---|---|---|
| Calcium | Dairy | Main source |
| Calcium | Leafy greens | Plant |
| D3 | Fatty fish | Fat-soluble |
| K2 | Fermented | Natto |
Practice
- Calcium from food daily.
- Vitamin D3 + K2.
- Bone-loading exercise (walking).
- Limit soda.
- Don't smoke.
- Consult a doctor.
