Customers say
Customers find this calcium supplement to be a great value and appreciate its quality, noting it contains Calcium Carbonate without Vitamin D. The supplement is easy to swallow and works well, with one customer specifically mentioning it performs better than calcium with Vitamin D3. The size receives mixed feedback – while some find the bottle nice, others say the pills are larger than preferred. The bottle quality is problematic, with multiple customers reporting that the lid broke immediately upon opening.

A rear find
One of very few options of calcium without including vitamin D.
Espanola –
No Vitamin D!
It is quite hard finding calcium tablets with no Vitamin D which are the ones I needed. These are a little large but well coated so easy to swallow.
Roberta Cragun –

Great job 21st Century!
I deal with degenerative arthritis in my spine,clavicle and Vitamin D deficiency hereditary so I go through it. Aches, pains,always worrying about falling because I can break something so easily. I love to dance,sports etc I’m such a tomboy at heart. It sucks always having to be cautious or not able to move around on bad days. On some days that it rains i go through it & i loveeeee the rain how ironic huh? I have been dealing with these issues since my early 20’s on top of scoliosis but I will not get surgery that will be my last option. These help me soooo much! I can’t put emphasis on that statement. *Simply love them.* These along with super collagen powder is a game changer. The price is right,the ingredients seem to be exactly what they state because I can feel the difference. When you have been taking supplements for a long time you know. Found these gems here on Amazon. I felt they wouldn’t do much because of the price but I thought what do I have to lose right? I didn’t lose a thing but gained some comfort and mobility. Will definitely keep in my order list as long as merchant keeps this price point and 21st Century doesn’t change the formula. Sometimes companies can’t leave just right alone,we all have seen it happen. Then you find yourself looking for a replacement & it’s a headache. I know you guys can relate. If you have this in cart or looking at these thinking on that buy now? Go ahead and do it. Best few bucks you can spend.
