A jog on a Hawaiian beach was all it took for Jan, a post-menopausal registered nurse, to fracture a bone in her foot. The sand shifted slightly as she took a step, and she felt the pain.
The vacation that Jan and her husband had anticipated for months? Ruined.
Jan always assumed she got enough calcium to keep her bones strong through her healthy diet and didn’t dwell on taking supplements before she entered menopause. Even her nursing training had only briefly touched upon nutrition.
If she had known the full truth, she might have spent more time in Hawaii outside of her hotel room, catching sun rays, instead of in the emergency room, getting x-rays. At Gennev HQ, we'll show why you need calcium, where to get it, and how much is enough.

Minerals like calcium are vital to a healthy body. Your bones and teeth are home to 99% of your body’s calcium, while the remaining 1% helps your blood clot, your nervous system relay information, your muscles and blood vessels contract, and performs many other functions.
Your bones are constantly remodeling, breaking down and rebuilding to repair injuries and the daily wear and tear from normal activities.
During bone remodeling, your bones release calcium into the bloodstream and reabsorb it back. If your body doesn't have enough available calcium, it will use the calcium released into your blood to repair nerves, cells, and muscles instead of reabsorbing it into your skeleton.
In childhood, our bodies build more bone than we lose. This is how we grow. From adolescence until our thirties, our bones are the strongest because they build up and break down at an equal pace.
In our mid-thirties, this changes. We start to lose bone mass faster than we can maintain it.
Bone loss speeds up when your body’s estrogen production decreases during perimenopause and menopause, as estrogen aids calcium absorption from food and reabsorption into bones.
This all can lead to osteoporosis, a condition where bones become porous, brittle, and break easily, and its precursor, osteopenia. Forty percent of post-menopausal women in the US will have an osteoporosis-related fracture at some point in their lives. Some women have even died from osteoporosis hip-fractuces . Our friend Jan is one of these women. If your mother or grandmother had osteoporosis, you are at greater risk of developing it.
The calcium that you consumed as a teen and young adult is what shapes your risk of osteoporosis entering menopause.
‘This is great for my daughter,’ you might say, ‘but how does it help me now?’
You can’t have your teenage body back, including your bones, but keeping adequate levels of calcium in your bloodstream as you enter menopause and beyond can help your bones stay strong.
For more than 20 years, the USDA has defined the recommended daily allowance (RDA) of calcium for American women as 1000mg for women 50 and under and 1200mg for women over 50.
Some nutritionists now suggest that as low as 500mg per day may be enough. However, more research is needed to support this conclusion.
The foods you eat are the most effective sources of calcium. Great sources of dietary calcium include yogurt (310 mg/serving), cheese (up to 210 mg/serving), sardines (325 mg/serving), cow’s milk (300 mg/serving), fortified soy milk or orange juice (300 mg/serving), tofu (205 mg/serving), and leafy greens (up to 360 mg/serving).

You can figure out how much calcium you’re getting from your diet by checking food labels or using a calcium calculator. Note: the “DV” (daily value) for calcium on food labels is based on 1000 mg, so “30% of DV” is 300 mg. If you are over 50, this isn’t 30% of your daily need!
Your doctor may also suggest taking a daily calcium supplement. For best absorption, take calcium supplements in doses smaller than 600mg; if you need more calcium than this, space out your supplement several times throughout the day
Calcium carbonate is the more affordable and available form of calcium supplement. You may already have calcium carbonate in your medicine cabinet as an antacid, like Tums or Rolaids. Take it with food, as stomach acid increases absorption.
Calcium citrate is another form of over-the-counter calcium. You can take it with or without food.
Side effects of calcium supplements may include gas, bloating, and constipation. Calcium carbonate tends to have more side effects than calcium citrate, so if you’re experiencing gastro discomfort, consider making the switch.
The amount of calcium that’s right for you may defer from the norm if…
Getting more than the RDA value of calcium may increase your risk of kidney stones, heart disease from increased calcification in the arteries, and potentially colon cancer, though more evidence is needed to support these claims.
Preliminary research shows that vitamin K2, which plays an important role in calcium metabolization, can help with heart health if this is a concern for you; be sure to talk to your doctor first.
(Did you know that vitamin K is great for your bones, too? Women who get at least 110 micrograms of vitamin K daily are 30% less likely to break a hip than women who don’t!)
Studies suggest that exceeding the RDA of calcium doesn’t actually increase bone health in patients with osteoporosis but meeting your daily needs now and taking preventative measures will reduce your risk of fracture in the future.
If you are 65+ or have risk factors for osteoporosis before entering menopause, get a bone mineral density test (BMD) to evaluate your bone health before you break something.
And remember that calcium is only part of the equation for strong bones: if you want toprevent osteoporosis, exercise, a healthy diet, and refraining from smoking.
Jan now maintains her bone strength by eating calcium-rich foods, doing yoga with her husband, and walking to the grocery store instead of driving. She can focus her attention on her book club and adult children knowing that she’s doing everything she can to prevent another fracture.
