  • New higher-strength, vegetarian capsule
  • Faster absorption vs. Calcium Carbonate
  • Supports bone, teeth & muscle health
  • Stomach-sensitive form of Calcium

Supplement Description

Calcium is the most abundant mineral found in the body, where it plays a number of important roles.

Essential for healthy bones and teeth

Some of the primary roles which calcium plays in the body are:

  • Maintenance of normal bones and teeth
  • Normal muscle function and neurotransmission
  • Regulating muscle contractions, including heartbeat 
  • Ensuring blood clots normally

Highly bioavailable premium formulation

Most Calcium supplements contain Calcium Carbonate, however our Calcium tablets use a citrate form which is more easily absorbed and carries all the same benefits. It may be of particular benefit to those who are sensitive to antacids or who have difficulty producing adequate stomach acid. Whereas Calcium Carbonate carries a risk of the stomach overcompensating by producing more acid, Calcium Citrate has no effect on stomach acid.


Formulated to maximise absorption into the body

The high bioavailability of Calcium Citrate, combined with the ease of absorption makes this form of Calcium particularly suitable for those aged 65 and over. For those on the go, it's a convenient option too, as Citrate can be taken without food, will dissolve quicker and is absorbed faster into the body compared with regular Calcium Carbonate.

Just two of our improved Calcium Citrate capsules contains 1000mg of Citrate, which provides 210mg of elemental Calcium (Ca) in a vegetarian capsule shell.

Review Details
Service Rating: From order to delivery I was very pleased with the fast and efficient service. I like the packaging as it can be put through a letterbox. I’m also very pleased with the product itself.
Product: They are calcium supplements in a product that help if you’ve a sensitive tummy.
Service Rating: Good quality and prompt arrival
Product: Good quality and no side affects
Service Rating: I ordered the capsules by post. The service was perfect, the agent on the phone was efficient, and the order was delivered to my home in good time. Thank you.
Product: I am taking these for osteoporosis. I prefer capsules to tablets. It’s difficult to say if they work but they are easy to swallow and I am doing what I can to avoid broken bones!
I had been looking for the tablets I wanted on the internet and just vitamins came up. I thought I'd try them to see what the experience was like. The website was easy to use. The tablets came quickly. I am very happy and would recommend them to friends
Service Rating: Well designed product, efficiently handled. Particularly applaud the letterbox-friendly packaging
Product: Looking for a low-dose calcium supplement, avoiding the alkalinity of calcium carbonate. This fills that need perfectly.
Well priced product and swift delivery.
Service Rating: Easy and straightforward. Arrived within a few days.
Product: I am taking it because I have osteoporosis. Other calcium supplements have some kind of processed sugar in them - saccharine or glucose - and I have an intolerance of them. They bring on headaches. these capsules do not contain anything that I cannot tolerate and I am really pleased. they also come in a pouch which is much easier to manage and store than a bottle.
Customer service was way beyond my expectation
Very helpful and honest
I’ve been using just vitamins since 2010 and very happy with both the product and service
Arrived promptly, in good condition.
Service Rating: This website is very easy to navigate. The products are fairly priced and the delivery is second to none !
Product: This is the 4th time I have ordered this supplement. I took me a longtime to find this particular combination of calcium, as many other brands use the cheaper form of calcium ie carbonate, which isn’t absorbed as easily. I take this for continued bone health.

Product: Right type of calcium. Take it for bone strength.
Service Rating: Always packaged well and arrive quickly whether I am in UK or Republic of Ireland.
Product: I am a bit concerned the strength may not be as advertised as my calcium levels are still low, this could be due to me having secondary cancer of the bones and not the tablets fault. I have to now double my dose, so probably is due to my body and not the tablet.
Service Rating: Good quality delivered promptly

Your vitamins are good and reasonably priced,but I've been waiting for about 3 weeks for part of my order to arrive and it's still not here.............its out of poor stock keeping!
Just Vitamins had just what I was looking for and provided detailed information about the product and relevant health information, which was what I needed.
