9 Best Calcium Supplements & Tablets For Women (2025)
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 – 1,300mg 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 100mg for those who need just a tad more, while others offer upwards of 1200mg 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.

Our Editor’s Review | “After 30 days with the supplement, I felt more energized and less bloated. My digestion has improved (thanks to the pre and probiotics), and I haven’t been sick or experienced my regular seasonal allergies. The addition of gut-supportive probiotics is also crucial for me right now as I’m on some other supplements and medications for fertility treatments, which can wreak havoc on hormones and the digestive system. I truly believe AG1 is why I haven’t noticed any negative impacts. And it keeps me regular, if you know what I mean.” – Kayti Christian, Senior Content Strategist [Read the full review.]

Customer 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.
