Osteoporosis

Osteoporosis is bone loss: bones become more porous and break more easily. It runs for years without symptoms, until a fracture is the first warning.

Practical use

For whom

Mainly women after menopause, older adults and people with earlier fractures.

Not for whom

Do not wait for a fracture: bone loss is silent, so timely measuring pays off.

In practice

Strength training, enough protein and vitamin D; medication (bisphosphonates) at higher risk.

Key caveats

Calcium and vitamin D alone are often not enough; loading the bones is essential.

"You will notice osteoporosis yourself."
False. It is silent until a fracture; that is why measuring matters.Strong evidence
"Just taking calcium prevents it."
Incomplete. Loading (strength training) and vitamin D matter at least as much.Moderate evidence

Osteoporosis: what's new, and what holds up

We follow the latest research on osteoporosis and listen to leading health podcasts, and we check what they claim. You'll get one email on Thursdays with what matters, and only when there's something new.

You can add more topics later, such as exercise or sleep.
