  • Feefo Reviews Reviews

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 capsules 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.

Review Details
Great service
Service rating: Well packed. Good product deliver.
Product: Required vitamin for bone density. Got my money’s worth.
Service rating: They were easy to order, arrived in good time, and they seem like they are good quality supplements.
Product: Nice packaging seems like good quality. It's really hard to find calcium on its own - often it's mixed with things so you can't top up a multivitamin easily - so this was really great to find.
Service rating: Excellent service from ordering to delivery on date specified
Product: Bought for my wife as she needed better tablets than the NHS prescribes
Seamless from ordering to delivery
Service rating: Well packed, quick delivery. Items as described
Product: As described, doctor says the tablets work well
Looks like scam
Feedback Response: Hi, I can assure you that we are not a scam. We appreciate that your order was lost in the post, this is rare and we immediately refunded your order back to you once we were aware.
Service rating: Pretty good service. Reasonable prices for quality products. However the zip close seal on vitamin packs often breaks, the zip fastening sometimes being stonger than the glue sealing it to the pack, which is annoying, meaning you no longer have an airtight seal.
Product: Reasonable price for quality supplement. Easy to swallow
Service rating: Good value and quick delivery.
Product: Only just changed to calcium citrate from carbonate, but no problems at all.
Service rating: Excellent service, excellent product with highly competitive price. I wouldn`t hesitate to recommend Just Vitamins.
Product: Good form of calcium - helps to strengthen bones.
As usual, great!!! I take lots of measures to stay as fit and healthy as I can and these vitamins are part of that routine. The COVID shutdown seriously restricted access to my training facilities (Glasgow Club), a sauna, a swim and the gym and this has cut the legs away from me to a fair degree. Still, thanks to my previous lifestyle, good food, lots of exercise and appropriate vitamins, I am still here (85) to get back into it.
Service rating: Efficient service
Product: Better absorption than calcium carbonate
Service rating: Very good service. Quick and easy to order and fast delivery. I have used this product for a long time and will continue so to do.

Service rating: A great service and at the end of the phone for help and advice.
Quick delivery too.
Product: A few months ago was prescribed and given calcium carbonate as levels was low. Took for couple of weeks but had quite a few side effects including stomach cramps, constipation and feeling queasy.
Decided to purchase calcium citrate from Just Vitamins. Have been taking them for quite a few months now-calcium levels much better and no side effects.
Would definitely recommend.
