The short explanation
Caffeine in tea and coffee can slightly increase the amount of calcium lost in urine, but for most people moderate amounts have only a small effect on bones, especially if they get enough calcium from food. Tea with milk also adds a little calcium. Very high caffeine intake, particularly with a low-calcium diet, may matter more for bone health, especially after menopause. If you drink several cups a day, it is reasonable to make sure your diet includes good calcium sources and to talk to your doctor if you have other risk factors for osteoporosis.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Other factors affect bones more than tea alone: age, menopause, family history, low body weight, smoking, heavy alcohol use, long-term steroid use and lack of exercise.
- Tea taken with meals can reduce iron absorption, which is a separate concern for women with anaemia.
- Strong tea or coffee late in the day can also affect sleep.
- If you would like to cut down, you could try replacing one or two cups with buttermilk, which also adds calcium, or having tea between meals rather than with them.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your bones are healthy. That needs a doctor's assessment and possibly a bone density scan.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Does my tea intake affect my bone health?
- Is my calcium intake from food enough?
- Do I need a bone density scan at my age?
- What else can I do to protect my bones?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Get help the same day
- Get care the same day if you fall and have pain in the hip, wrist or back, or cannot bear weight.
Book an appointment soon
- See a doctor within a few days if you notice sudden back pain without injury, loss of height or a stoop developing.
Raise it at a routine appointment
- Book a routine appointment to discuss bone health after menopause, especially if you have a family history of fractures.
