Calcium and vitamin D after menopause: how much you need

Calcium needs go up at 51, at the same time as bone loss speeds up. Here are the numbers, the foods that deliver them, and the limits to respect.

Reviewed by Claudia Muresian, health psychologist, fitness coach and healthy nutrition specialist Researched and drafted by the Fit Over 40 editorial team. Last updated November 11, 2026. 6 minute read. How we research and review

The short version

  • Women need 1,000 mg of calcium a day up to age 50 and 1,200 mg a day from 51.
  • After 50, total calcium from food and supplements should stay under 2,000 mg a day.
  • US health guidance suggests 800 to 1,000 IU of vitamin D a day for adults over 50, with an upper limit of 4,000 IU.
  • Food is the preferred source. It is not clear that calcium supplements prevent fractures.
  • Weight-bearing exercise and, for some women, hormone therapy also protect bone.

The daily targets

Why the target rises at 51

Estrogen helps bone hold on to calcium. When estrogen falls at menopause, bone is broken down faster than it is rebuilt. In the United States, about four in every twenty women over 65 have osteoporosis.3 Getting enough calcium and vitamin D will not stop bone loss on its own, but falling short makes it worse.

Calcium in everyday foods

FoodServingCalcium
Plain yogurt1 cupabout 370 mg
Tofu made with calciumhalf a cupabout 250 mg
Cheddar cheese1 oz (28 g)about 200 mg

Source: Bone Health and Osteoporosis Foundation.4 Other useful sources include milk, fortified soy milk, canned sardines and salmon eaten with the bones, kale, bok choy, broccoli and fortified cereals.1,3

A day with a yogurt bowl at breakfast, sardines on toast at lunch and a tofu stir-fry at dinner covers most of the target from food.

Vitamin D

Vitamin D lets your gut absorb calcium. Your skin makes it in sunlight, and a few foods supply it: salmon, tuna and trout, egg yolks, and milk, soy milk, cereals or yogurts with vitamin D added.3 Because food sources are limited, some women need a supplement, especially in winter. Talk to your doctor before starting one.3

What about supplements?

  • Use a supplement to fill a gap, not to replace food.
  • More is not better. Too much calcium or vitamin D can cause problems such as kidney stones.2
  • Studies disagree on whether calcium supplements improve bone density in older adults, and it is not clear that they prevent fractures.1
  • The balance of benefit and harm from these supplements remains uncertain, so decide with your doctor.2

Bones need more than calcium

  • Load them. Bones respond to impact and resistance. The World Health Organization advises muscle-strengthening activity at least twice a week.6 Try our beginner dumbbell workout.
  • Eat enough protein. See how much protein women over 50 need.
  • Do not smoke, and keep alcohol low. Both are linked to weaker bones.2
  • Ask about hormone therapy if you are at risk. It has been shown to prevent bone loss and fracture, and it has its own risks to weigh.5

Common questions

Is it better to take calcium in the morning or at night?

Timing matters less than dose. If you use a supplement, smaller amounts taken with food are the usual advice. Ask your pharmacist about spacing it from thyroid medicine, some antibiotics and iron, because calcium can interfere with their absorption.

Can I get enough calcium without dairy?

Yes. Calcium-set tofu, fortified soy and other plant drinks, canned sardines or salmon with bones, kale, bok choy and fortified cereals all contribute. Check labels, because fortification varies by brand.1,3

Should I have my vitamin D level tested?

That is a decision for you and your doctor. People who get little sun, cover their skin, have darker skin or have a condition that affects absorption are more likely to be low.
