Calcium and calcium tablets for menopause
Women aged 51 to 70 need 1,200 mg of calcium a day, up from 1,000 mg before 50, and food is the preferred source. Tablets help if your diet falls short, but in healthy postmenopausal women the USPSTF found that 1,000 mg or less of calcium with 400 IU or less of vitamin D didn't prevent fractures and raised kidney stone risk. Take supplements in doses of 500 mg or less, and pair calcium with enough vitamin D.
Women 51 to 70 need 1,200 mg of calcium a day, ideally from food. When tablets make sense, carbonate vs citrate, 500 mg at a time, kidney stone risk, and vitamin D.
Calcium in menopause: expectation vs reality
What people often expect
“Taking a calcium tablet every day after menopause will prevent osteoporosis”
What the evidence shows
Calcium is necessary for bone, but pills alone haven't been shown to prevent fractures in healthy postmenopausal women. The USPSTF recommends against low-dose calcium and vitamin D for that purpose. A meta-analysis also found calcium supplements linked to more heart attacks (relative risk 1.24). Food calcium, exercise and, when needed, osteoporosis treatment matter more.
Calcium for menopause: how much you need and from where
How much calcium do you need in menopause?
US Dietary Reference Intakes set calcium at 1,000 mg a day for women aged 19 to 50 and 1,200 mg from 51. The Office on Women's Health says women 51 and older should get 1,200 mg a day because after menopause women need more calcium to maintain bone health. The UK sets a lower figure, 700 mg a day for adults, which shows how much guidelines vary.
Calcium-rich foods
Dairy products are the best-absorbed source: milk, yogurt, cheese and buttermilk, and low-fat versions keep the calcium. Other sources include canned salmon and sardines with bones, almonds, tahini, dried beans, broccoli, kale and bok choy, plus fortified soy milk, tofu, orange juice and cereals. Spinach contains calcium but binds much of it, so it isn't a reliable source.

Not at low doses in healthy women. The USPSTF found adequate evidence that 1,000 mg or less of calcium with 400 IU or less of vitamin D daily has no benefit for preventing fractures in community-dwelling postmenopausal women, and recommends against it. Evidence for higher doses was insufficient. This doesn't apply if you have osteoporosis, vitamin D deficiency, a past fracture or a high fall risk.
Learn more →Calcium supplements and heart risk
In a reanalysis of Women's Health Initiative data and a meta-analysis of placebo-controlled trials, calcium with or without vitamin D was linked to more heart attacks (relative risk 1.24). The finding comes from a reanalysis rather than a trial designed to test it, but it's a reason to prefer calcium from food. If you need a supplement, avoid taking more than you need.
Calcium carbonate vs calcium citrate
Calcium carbonate is cheaper and absorbed better with food; it's the calcium in antacids like Tums and Rolaids, which usually provide 200 to 400 mg per chew. Calcium citrate is more expensive but is absorbed well with or without food. Whatever the form, absorption is best in doses of no more than 500 mg at a time, so split larger amounts.
Calcium and vitamin D together
Vitamin D helps your body absorb calcium, which is why milk is fortified with it. Adults need 600 IU of vitamin D a day to age 70 and 800 IU after that. The 2026 International Menopause Society review found moderate-certainty evidence that vitamin D lowers fracture risk and high-certainty evidence that it's safe.
Learn more →Side effects of too much calcium
Higher calcium intake over a long time raises the risk of kidney stones in some people, and the USPSTF confirmed that vitamin D and calcium supplements increase kidney stones. The NHS says more than 1,500 mg a day from supplements can cause stomach pain and diarrhea. Some medicines affect calcium absorption, so tell your provider what you take.
Protecting bones beyond calcium
Bone health after menopause depends on more than calcium: weight-bearing and muscle-strengthening exercise, vitamin D, not smoking and limiting alcohol all matter, and HRT reduces the risk of osteoporosis. The USPSTF recommends bone density screening for women 65 and older and for younger postmenopausal women at higher risk.

How to choose and take a calcium supplement
- Estimate your food calcium first and supplement only the shortfall toward 1,200 mg.
- Check the Supplement Facts panel for the actual calcium amount per tablet.
- Split doses to 500 mg or less, and take carbonate with meals.
- Talk to your doctor if you've had kidney stones or take thyroid or other regular medicines.
When to ask a doctor about calcium in menopause
You've had a fracture from a minor fall
Ask about osteoporosis testing and treatment; calcium alone isn't enough.
You're 65 or older, or younger with risk factors
Ask about bone density screening.
History of kidney stones
Check before taking calcium or vitamin D supplements.
Stomach pain or diarrhea on calcium
Reduce the dose and talk to your doctor.
Calcium supplements in menopause: questions women ask
How much calcium should a menopausal woman take?
Aim for 1,200 mg a day from all sources from age 51, per US guidelines. Get as much as you can from food and supplement only the gap.
Should I take calcium supplements after menopause?
Only if your diet falls short. In healthy postmenopausal women, low-dose calcium with vitamin D didn't prevent fractures and increased kidney stones, and the USPSTF recommends against it for that purpose.
What is the best calcium supplement for menopause?
Calcium citrate is absorbed well with or without food; calcium carbonate is cheaper but should be taken with food. Pick the dose that fills your dietary gap, split into 500 mg or less.
Should I take calcium with vitamin D in menopause?
Vitamin D helps you absorb calcium, and adults need 600 IU a day to 70. Many products combine them, but low-dose combinations didn't prevent fractures in healthy women.
Can calcium supplements cause heart problems?
Possibly. A meta-analysis of placebo-controlled trials linked calcium supplements to more heart attacks (relative risk 1.24). MedlinePlus names calcium-rich foods as the preferred source.
Can I get enough calcium without dairy?
Yes, with fortified soy milk, tofu, orange juice and cereals, canned fish with bones, almonds, tahini, beans and greens like kale and bok choy.
Does calcium help menopause symptoms?
No. Calcium supports bones but hasn't been shown to ease hot flashes or other symptoms. For symptoms, HRT and proven non-hormonal treatments work better.
When is the best time to take calcium tablets?
Take calcium carbonate with meals; calcium citrate can be taken any time. Spread larger amounts through the day in doses of 500 mg or less.
