7 Best Calcium Supplements For Women (Tablets And Powders)
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
Our team has tested and researched dozens of calcium supplements for the cleanest options that absorb well and taste great — these are our top picks for women.
If you grew up seeing Got Milk? ads, you probably remember how vital calcium is 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. That’s why we turn to calcium supplements to help us make sure we’re getting our daily dose in!
How much calcium do women need?
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. Calcium is a mineral that’s crucial for building and maintaining strong and healthy teeth and bones—it also assists in wound healing and preventing muscle cramps. Consuming proper amounts of calcium each day can help reduce the risk of osteoporosis later in life and preeclampsia in pregnant people. Calcium is also best absorbed when paired with vitamin D, as without it, the body only absorbs around 10-15% of calcium.
If you do 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.
Our criteria:
- CLEAN INGREDIENTS | We’ve listed the best calcium supplements made with natural and organic ingredients that are safe and healthy for us to consume.
- ABSORPTION | We’ve made sure to feature supplement brands that include ingredients like vitamin D to help absorb calcium effectively.
- TASTE/FLAVOR | Each of these supplements offer delicious flavors with no off putting aftertaste, making them easy to take on the daily.
In addition to these calcium supplements, check out our guides on clean protein powders and organic multivitamins for helping us keep our bodies healthy and our immune system in top shape.
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.

They come in a tasty flavor (peach mango apricot), are kid-friendly, and don’t contain any gelatin or gluten. The D3 and K2 vitamins help the 100 mg calcium absorb quickly and effectively, and with just one gummy a day, you’ll feel the difference in just a few weeks. Based in Los Angeles, you can purchase online, check out their Find a Store section, or pick up your own gummies at Target, Vitamin Shoppe, or Vitacost.
Mary Ruth Organics Review | “I don’t find a lot of D3 with K2 and Calcium together and certainly not in a gummy. My teenage son is a beginner pill swallower so typically he’d be just fine with small vitamin D pills but these he looks forward to. I’m a POC so with my melanin it’s harder for me to get my proper daily levels so my doctor recommended 2000 IU a day. We take two gummies daily. I have not had my blood work checked again since I’ve been taking them but due to some of my other Mary Ruth’s products that have had more immediate tangible results I trust these products completely and am looking forward to my next doctor visit in confidence.” – Leah P.
