What customers say
Customers highly appreciate the calcium plus vitamin D3 supplement for its quality and effectiveness in improving bone health. Many users report noticeable improvements in overall health, increased energy levels, and better digestion after a few weeks of use. The product is praised for its reasonable price, good packaging, and sufficient dosage with each tablet containing 1000 mg of calcium. However, some customers find the tablets large and difficult to swallow, suggesting they might need to be cut in half. Despite this, the supplement is considered an essential part of daily routines for many, with repeat purchases indicating high satisfaction. Users also commend the ease of taking just one pill a day and recommend it for maintaining strong bones.

This is the 1st time I will try this supplement. I'll order again if I see any difference. No taste. Quite big in size.

Well packaged and good for all age groups

The packaging is really nice. I like to take calcium with the vitamin D. The ingredients are good and it's age-appropriate. The quality is amazing and I use it every three days. It is a good supplement for people with deficiency in calcium and D3. The combination is good and I see improvement. It's good for the bones and and the deficiency in calcium.

Essential Calcium: A Foundational Supplement for Women
Verified purchase
In the past year, I learned just how vital calcium supplements are, particularly as we age. This is especially true for women over 30 and those who are pregnant or breastfeeding, as calcium deficiency is surprisingly common in these groups. The quality of this supplement is excellent, and its chief benefit is supporting long-term skeletal health. It is essential to keep your bone structure strong from an early age to greatly reduce the risk of future conditions like osteoporosis. This supplement offers a significant improvement in my daily mineral intake. I am very pleased that this product is formulated as a beneficial combination with Vitamin D, which is crucial as it helps maximize calcium absorption. The ingredients list is clean and focused on this core nutritional benefit.

Good Supplement

I love the value I get out of this bottle! So affordable, I actually can’t believe you get a 3-month’s supply for under $10. I’m not a fan of the added colors such as Blue #2 and Yellow #5, but I can’t complain when the price is so low. The combination of Vitamin D and Calcium helps absorption, so that’s a nice touch.

a good dose of CA!
Verified purchase
This tablet (to which is added the required daily Camille of D3 vitamin) contains some three quarters of the calcium you need each day. Quite big, swallow with water. If you don't eat dairy nor drink milk and don't have tahina on a specific day, go for 2!

Reliable Calcium & D3 Combo for Strong Bones
Verified purchase
This is a great and affordable calcium supplement with added Vitamin D3 to help with absorption and bone support. I take it daily to maintain bone strength and overall health, and I’ve had no issues with digestion or taste. The tablets are a bit large, but manageable, and the ingredient quality feels trustworthy, especially from a well-known brand like 21st Century. It’s a great option for those who want to maintain healthy bones — especially if you’re not getting enough calcium or sun exposure from your daily routine. I’ll definitely be repurchasing!
