⸻ 💇‍♀️ Is it good for hair? 👉 Minor direct effect • Calcium does not directly promote hair growth • But if there is not enough of it in the body → hair may become weak 📌 More important for hair: • Vitamin D3 • Omega-3 • Iron, biotin ⸻ 🦵 Benefits for legs (bones): 👉 Yes, very important • Strengthens bones • Good for joints, teeth, nails • Helps with pain or weakness in the legs

I took 21st Century Calcium Citrate Maximum + D3 (120 tablets) for several months and liked the combination of easily absorbed calcium citrate and vitamin D3. The quality is truly noticeable, providing bone support and overall well-being. The tablets are easy to add to your daily diet, absorb well, and don't cause any stomach discomfort. An excellent option for maintaining bone and joint health at an affordable price.

The main ingredients are only calcium citrate and vitamin D3, and it does not contain high doses of the mineral magnesium...

Verified Purchase

Calcium maintains bone health, magnesium relaxes muscles, and vitamin D3 promotes calcium absorption and regulates immunity. While this product is named "Calcium Citrate Magnesium + D3," its "main active ingredients" are only calcium citrate and vitamin D3, omitting magnesium, a key nutrient. Although often translated as "Calcium Citrate Magnesium" in Taiwan, it lacks high-dose magnesium because the "Other Ingredients" section on the back of the product list contains trace amounts of magnesium silicate and magnesium stearate for tablet shaping and manufacturing. The amount of magnesium in these tablets is extremely small and insufficient to provide any magnesium supplementation, muscle relaxation, or sleep aid benefits. However, this extra-large calcium citrate + D3 tablet is primarily designed for efficient calcium supplementation, maintaining bone strength and dental health; it is less likely to cause gastrointestinal discomfort, can be taken on an empty stomach (no stomach acid required), and has a high absorption rate. This is purely my personal sharing of my experience using this "Calcium Magnesium Citrate + D3" product. The ingredients are suitable for all ages, and I hope it will be helpful to everyone… If you've read this review, please don't hesitate to give it a like to encourage me! ^^

very good!

Verified Purchase

I've tried 4-5 different calcium supplements, and this is the only one I'm still using. It doesn't cause stomach upset, and the tablets aren't too big to swallow.

I recommend it

Verified Purchase

21st Century Calcium Citrate + D3 Maximum is a good calcium supplement. I liked that it contains calcium citrate, which is usually better absorbed. The tablets last a long time, and the vitamin D3 in the composition is a big plus. I took it comfortably, without any unpleasant sensations from the stomach.
