If you grew up seeing Got Milk? ads, you probably remember how calcium is vital for bone health. And while, yes, you can find calcium in dairy, it’s not always easy to get all the calcium you need—especially if you are vegan, have a sensitivity, or experience illnesses like IBD or celiac disease.

Adult women are recommended to have 1,000-1,300 mg of calcium a day, per the Mayo Clinic and the National Institute of Health. If you have a calcium deficiency and can’t solve it through diet alone, consider these calcium supplements below to help close the gap—some start at 100 mg for those who need just a tad more, while others offer upwards of 750 mg in each serving.

And as always since over-ingesting calcium can cause issues, too, we recommend speaking with your primary physician to figure out what serving is right for you.
