Some over-the-counter antacids, such as Tums and Rolaids, also contain calcium carbonate .suitable for all ages , lake of calcium cause Osteoporosis, which causes weak, fragile bones and increases the risk of fallin.

Highly satisfied with this product. It does not make one feel like he has been running a marathon every day for five years, but regular use of this product was able to help my brain function as well as my body. I am very glad I chose to purchase and try out this supplement.

I’ve been using this for a long time and I’m a breastfeeding mom. Size of the tablet is bigger but understandable. Quality is superb and I love that it’s ingredients are natural. I like that it’s cheaper here than in other stores here in our country. Thank you iherb!!!

As a lactating mum, my doctor suggested consuming additional calcium so that my bones will remain strong while contributing calcium to my baby at the same time. While some brands require consuming 2 or more tablets a day based on the dosage, I found 21st Century's 1000mg tablet to be much more convenient since we just need to consume one a day. It's great that vitamin D has been added to aid absorption too. This way I don’t have to separately consume vitamin D which I was told I'm lacking due to too much cooping up at home.

Value for money! It really helps dry skin, you can consume or use the liquid in a face cream. It absorbs well with FATTY foods so consume with fish, meat, dairy, avocado, etc. Acidic foods also help absorption so some citrus fruit or orange juice with a meal will help. don’t take on a empty stomach as nausea happens. If this review was useful please like :)

A pretty good supplement for improving the quality of life. I used it for a long time, several months, up to 7 weeks. It was not too hard to find it in the supermarket. I do not notice any side effects (minimal but noticeable).

I would like to say how grateful I am for the vitamins that were given to me. They were easy to take and in no time, I noticed a change.
