  • Product Information

  • Introducing our high-quality Calcium Citrate 800mg tablets, the perfect addition to your daily routine for the maintenance of normal bones, teeth and muscle function. With 6µg of vitamin D for normal absorption/utilisation of calcium, our supplement offers a convenient and effective way to meet your calcium and vitamin D needs in a 3 a day dose.

    Calcium is an essential mineral that has a critical function in preserving strong bones and teeth. It is necessary to consume 700mg of calcium on a daily basis. It is especially important for individuals at risk of calcium deficiency, such as women during the menopause, during pregnancy, older adults and those with limited dairy intake. Our Calcium Citrate supplement provides a high strength dose of 800mg of calcium per 3 a day serving, ensuring you receive the optimal amount to support bone density and strength.

    In addition to calcium, our supplement contains 6µg of vitamin D. Vitamin D is a key nutrient that aids in the absorption and utilisation of calcium and is recommended, especially during the winter months when sunlight exposure is low, or when little time is spent outdoors. Calcium and vitamin D also have a role in the process of cell division. By combining calcium and vitamin D in one formula, our supplement offers comprehensive support for your bone health.

    Our Calcium Citrate 800mg supplement is made from high-quality ingredients, ensuring purity and strength. It’s citrate form facilitates easy absorption by the body, maximising its bioavailability. Simply take 3 tablets daily with a meal or split the dose and have 1 tablet 3 times a day with food.

    When it comes to your health, quality matters. Our formula is made in UK factories working to Good Manufacturing Practice (GMP) to ensure our quality standards are always achieved. It is also free from common allergens, such as gluten, dairy, and artificial additives and vegetarian friendly, making it suitable for a wide range of dietary needs.

  • "Does What They But Very Large Tablets"
    By Karla , 01 Nov 2025
    [I received this product in exchange for my honest review] These are quite large and you have to take 3 with a meal.
    They don't have a taste and are easy to swallow if you take them individually.
    Given how many you have to take they are quite expensive compared to other brands but I have found that I don't feel as lethargic as I am when I didn't take them.
    As a vegetarian who eats limited dairy calcium is very important for me to be healthy.

    Thank you for taking the time to leave a review.

    Calcium citrate is a large compound which does result in the tablets being on the larger side. We do formulate our products to be as small as possible, whilst still providing a relevant level of the nutrients required. For future reference, you can see the size of our tablets / capsules against a ruler on the product pages on our website. If you would prefer a smaller calcium tablet, I would suggest our Chewable Calcium (code 739).

    Whilst we know that we are not always the cheapest, we take great pride in manufacturing supplements to the highest quality. Calcium citrate is a highly absorbable form of calcium, useful for those who have specific health concerns or struggle to absorb other forms of calcium.

    "Easy To Swallow And Digest"
    By Victoria , 29 Oct 2025
    [I received this product in exchange for my honest review] I've been trying out the Calcium Citrate 800mg food supplement vitamins for the last two weeks. They are quite big, but as they are so smooth, they are really easy to swallow. The pot they come in is easy to open and close, making it perfect for people with dexterity problems, and the writing on the label is in plain language that is easy for everyone to understand and can be translated via apps really easily too. I've had no issues since starting these tablets, and the only problem I've had is trying to remember to take them, lol

My skin looks smoother and less “aged” My joints feel a lot better, and I feel more active due to this. Although the tablets are larger the most tablets they are very easy to swallow and digest well.
