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; Calcium Carbonate carries a risk of the stomach overcompensating by producing more acid while 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.

Product: I'm taking calcium as a post-menopausal woman as advised by the medical profession. Whether they work or not, I honestly can't say. I broke my ankle a couple of years ago but maybe I would have with or without calcium. I'm just hedging my bets here!
Service rating: I like this product for the following reasons:-
1. I prefer calcium citrate as it is more soluble than calcium carbonate, which is usually used in calcium supplements.
2. It is one of the very few calcium supplements which is in capsule form as I struggle with swallowing tablets.
3. It has mo maize or corn filler which is very commonly used and I have a significant food intolerance to corn.
4.There is no plastc container as they come in a thickened paper pouch which is excellent and a much greener way of containing the capsules. The pouch also reseals very well.
5.I think for 45 days supply (90 capsules - two daily) of a product of this quality and which suits me so well that the price is quite reasonable.
Product: Already done. See my previous review.
Service rating: The item I wanted was delivered promptly yes I would recommend to a friend. On their internet site they give a full and detailed information on each product that they handle.
Product: The item was ordered because I have osteoporosis the supplement was just what I wanted.

Product: I need extra calcium in my diet because of a medical condition.
Service rating: The website was easy to use, products seem good and delivery was very quick! Will use again
Product: I've only been taking them for a short time due to calcium deficiency. There's no visible/physical difference to me, but I wasn't expecting one. Unlike the cheaper calcium supplements this hasn't given any constipation like the higher dose prescription from the doctor. This is the highest strength Calcium 'citrate' I could find. Pills are largish but I have no problem swallowing them. Time will tell, but so far it's all positive for this product.
Service rating: Quick delivery,good packaging andreally good quality vitamins.

Product: Good product competitive price
Service rating: Speedy delivery. Excellent product. I shall certainly be ordering again.
Product: As a retired nutritional therapist, I take great care over my choice of supplements. This capsule is so much easier to take than the previous huge tablets I had. At 84, I take Calcium Citrate with other supplements to improve bone density & also to counteract symptoms caused by a build-up of oxalates (muscle & joint aches, urethritis & kidney stones). The Citrate form is well-absorbed & particularly effective at counteracting oxalates.
Service rating: Fast delivery no hassle just great quality service
Product: Great stuff my bones hurt so much and these help
Service rating: Excellent products at good value and fast delivery.

Service rating: quick and courteous service and delivery
Product: Have been taking for many years because i'm vegetarian and need certain supplements
Service rating: Good product, promptly dispatched.
Product: I'm not sure how I can really rate a vitamin because who knows whether it's working or not! It's calcium so it's not as if it's meant to relieve pain where it can be judged as efficient or not.
Service rating: Love that many supplements are available in capsule form. Superfast despatch too. Highly recommend.
Product: Great price for capsules.
Service rating: Excellent service, fast delivery, good prices. They have a wide selection of stock.
Product: Great product easy to swallow
Service rating: Easy and efficient.
Product: Don't know how effective they are but have started taking them due to the fact am on steroids and need to make sure I have enough calcium to help prevent osteoporosis.
Also just calcium without additions which is what I wanted.
Service rating: Very quick -happy to use again. Not sure why bags have to be so big -seems like a waste. Especially if they’re plastic -(are they?)
Product: Can’t say I notice difference but I’ve got osteoporosis so... I take with calcium citrate
Service rating: Very pleased - have used this online retailer before and will definitely use again ;-)
Product: Calcium citrate for bone strength - these tablets are very well tolerated, whereas others I've tried upset my stomach. A win-win!
Service rating: Speedy delivery! Thank you!
Product: Excellent! Well pleased.
Arrived quickly. So far so good. Capsules are easy to swallow. Will you this product again. Probably look at other items next time.

Service rating: Superb service great prices and free delivery
Trying the 4000iu vit d due to low vit d and being diagnosed with an auto immune problem which can be caused due to low vit d. Started at 12000 iu daily felt better after first day more energy and less aches. I will continue with 12000 iu for a month then perhaps reduce to 8000iu for a month then down to 5000 iu maintenance. I take my vit d with omega 3 as you need fat to absorb the vit d and magnesium.
Product: They don't upset my tummy. Taking calcium citrate due to menopause and osteoarthritus.
Service rating: Order came quickly, best price I could find online. Very happy
Product: We take for tooth and bone strength, my teenage daughter doesn't really eat any dairy and so we read up on calcium Deficiency and decided to try a supplement
