Calcium & Vitamin D3 Gummies or Calcium Tablets: Which Do You Need?

Have you moved from cows’ milk to an oat or almond drink, and wondered whether the calcium moved with you? It is a fair question, and UK rules give calcium a clear set of sentences, word for word [1]. Calcium is needed for the maintenance of normal bones. Calcium is needed for the maintenance of normal teeth. Calcium contributes to normal muscle function. The NHS names milk, cheese and other dairy foods first among the sources of calcium, so a switch away from cows’ milk can leave less of it in your day [2]. One tablet or two gummies a day give you a measured amount, whatever is in your glass [4].

Wondering which calcium supplement to go for? It’s much simpler once you know what the numbers on the label mean. Our tablet says 400mg and 50%, our gummies say 500mg and 63% with a vitamin D3 line at 500%, and each percentage counts against the labelling reference, not the NHS figure [4]. This guide walks you through what those percentages mean, what each label declares and which of our three calcium products fits your day.

Calcium tablets, calcium gummies or calcium magnesium zinc: which is right for you?

All three carry the same authorised sentences for calcium, because the sentences belong to the mineral, not to the format [1]. They differ in how much calcium, what comes with it and the price for a day.

Calcium tablets 400mg: calcium on its own, one a day, about 5p

Want calcium on its own? Our Calcium Tablets 400mg give 400mg from calcium carbonate in a vegan tablet, one a day, for 180 days at about 5p a day [4]. It is one of the minerals in our range and has no vitamin D in it, so it fits in easily with any vitamin D you may already be taking.

Calcium and vitamin D3 gummies: 500mg with 25µg of vitamin D3

If you would rather chew, and want vitamin D3 in the same serving, our Calcium and Vitamin D3 Gummies give 500mg of calcium and 25µg of vitamin D3 in two gummies, set with pectin, for 30 days at about 33p a day [4].

Calcium magnesium zinc: three minerals and a little vitamin D in one tablet

If you want magnesium and zinc alongside calcium, our Calcium Magnesium Zinc tablets give 450mg of calcium with 250mg of magnesium, 15mg of zinc and 2.5µg of vitamin D3, for 90 days at about 6.7p a day [4].

Taking a calcium supplement with a multivitamin

Already taking a multivitamin? Our MultiVitamin & Minerals gives 200mg of calcium in one tablet and our Women’s Multivitamins give 250mg in two, and both sit in our multivitamins range [4]. The plain tablet and the gummies carry no zinc, so either sits alongside them.

The combined tablet brings 15mg of zinc, and its label asks you not to add another zinc supplement [4]. So if you already take a multivitamin or a zinc capsule, choose either that product or the combined tablet as your zinc for the day.

To help you compare, here are our three calcium labels side by side. Prices are correct at the time of writing.

How much calcium do you need a day? What the NHS says

The NHS gives one figure for adults.

“Adults aged 19 to 64 and over need 700mg of calcium a day.”

NHS

Calcium, nhs.uk [2]

What does calcium do in your body? The authorised sentences quoted in full below give the answer: calcium contributes to normal muscle function and to normal blood clotting [1].

Calcium in food: dairy, fortified drinks, kale and fish with bones

The NHS list is milk, cheese and other dairy foods, green leafy vegetables such as curly kale and okra, soya drinks with added calcium, bread and anything made with fortified flour, and fish where you eat the bones, such as sardines and pilchards [2]. Spinach is the exception: it holds a lot of calcium, but the body cannot digest it all [2]. An oat or almond drink counts only when the carton says calcium was added.

Vitamin D and calcium: the NHS winter advice

When it comes to vitamin D, the NHS offers clear advice in one sentence: “Government advice is that everyone should consider taking a daily vitamin D supplement during the autumn and winter.” [3] Adults need 10 micrograms a day, and between October and early March we do not make enough from sunlight [3]. The gummies give 25µg, the combined tablet 2.5µg, and the plain tablet none [4].

Calcium on the label: 400mg, 50% and why the NHS number is different

The simplest place to begin is our tablet’s panel, which has one line: calcium 400mg at 50% of the nutrient reference value [4]. That percentage counts against 800mg, the reference used on supplement labels, while the NHS figure of 700mg is dietary advice, which is why the same tablet reads 50% on the pouch and 57% against the NHS.

Nutrition information panel of Alpha01 Calcium Tablets 400mg: serving size 1 tablet, 180 servings per container, calcium 400mg, 50% NRV

400mg ÷ 50% = 800mg, the labelling reference on every panel · the NHS figure is 700mg a day, so one tablet is 57% of it, two gummies 71% and the combined tablet 64% · £8.99 ÷ 180 = about 5p a day.

The label maths

Calcium Tablets 400mg, nutrition panel and price, and the NHS calcium figure [4]

Calcium carbonate and tricalcium phosphate: the forms on our labels

The tablet and the combined tablet name calcium carbonate, and the gummies name tricalcium phosphate [4]. Both are recognised forms of the mineral, and the authorised sentences for calcium apply whichever one is used [1].

Calcium gummies: what the ingredients list says besides calcium

The gummies list cane sugar, tapioca syrup and water before the calcium, then pectin as the gelling agent, citric acid and sodium citrate, curcumin for the colour, natural strawberry flavour and vitamin D3 [4]. Pectin is a plant gelling agent, which is why the bottle can say vegan.

Vitamin D3 gummies: 25µg and 1,000 IU on the panel

The panel prints vitamin D3 as 25µg and as 1,000 IU, because 1 microgram of vitamin D is equal to 40 IU [3] [4].

Calcium benefits: the claims UK rules authorise

In the UK a food supplement may carry only the health claims authorised on the Great Britain Nutrition and Health Claims Register [1]. A calcium claim needs 15% of the reference value, which is 120mg, and every product on this page is well above it.

Every health claim on the Great Britain register passed a scientific review: independent scientists examined the research and the evidence behind it before it was authorised [1]. The law itself says that health claims shall be “based on and substantiated by generally accepted scientific evidence” [5].

Calcium and vitamin D on the register: the authorised sentences

Here are eight authorised sentences for calcium, each quoted word for word.

Our gummies and combined tablet also declare vitamin D, which brings seven more authorised sentences [1]:

These sentences describe the everyday work calcium and vitamin D do in the body. The calcium sentences apply in full to all three products, and the vitamin D sentences to the gummies and the combined tablet.

The combined tablet also declares magnesium and zinc, which carry sentences of their own: magnesium contributes to a reduction of tiredness and fatigue, and zinc contributes to the normal function of the immune system [1]. You can find all of them in our calcium magnesium zinc guide.

How to take calcium tablets: one a day with water

The tablet’s directions are one line: take one tablet daily with water [4]. The gummies say chew two gummies daily, and the combined tablet one tablet daily with water.

Six months of calcium tablets

If one vegan tablet a day suits your routine, a pouch of 180 covers six months for £8.99, about 5p a day.

Calcium FAQs

1. What are the benefits of calcium tablets?

Calcium is needed for the maintenance of normal bones and teeth and contributes to normal muscle function, among eight authorised sentences for calcium quoted word for word above [1]. They belong to the calcium, so they are the same whichever product you choose, and the gummies and the combined tablet add seven more for vitamin D.

2. How much calcium a day do adults need?

“Adults aged 19 to 64 and over need 700mg of calcium a day.” [2]

3. Is a calcium 400mg tablet enough on its own?

One tablet gives 400mg, 57% of the NHS figure, alongside the calcium in your food [2] [4]. If you’d like more in one serving, two gummies give 500mg with vitamin D3, and the combined tablet 450mg [4].

4. Can I take too much calcium?

The NHS says that if you take calcium supplements, 1,500mg or less a day is unlikely to cause any harm [2]. One tablet gives 400mg, two gummies 500mg and the combined tablet 450mg, so each sits well within that figure [4]. For vitamin D, the NHS advises no more than 100 micrograms (4,000 IU) a day, while two gummies give 25µg and the combined tablet 2.5µg [3] [4].

5. Calcium gummies or calcium tablets: which gives more calcium?

Two gummies give 500mg and one tablet 400mg, so the gummies give more calcium a day, with 25µg of vitamin D3 beside it, at about 33p a day against about 5p [4].

6. Do calcium tablets need vitamin D with them?

The register authorises the sentence “Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus,” and the NHS advises everyone to consider a daily vitamin D supplement in autumn and winter [1] [3]. Our plain tablet has none, so the gummies, the combined tablet or a separate vitamin D product cover that.

7. Are calcium tablets and calcium gummies vegan?

The tablet front says vegan tablets, its coating is hypromellose, and the gummies front says vegan gummies, set with pectin rather than gelatin [4]. The combined tablet says vegetarian.

8. Can I take calcium every day?

Yes. Each label gives a daily amount, one tablet or two gummies, so they are made for daily use; just don’t take more than the label says [4].

The calcium tablet is not intended for children under the age of 12 years, the gummies are not suitable for children, and the combined tablet is not intended for children or for pregnant or breastfeeding women [4]. All three labels ask you to consult a doctor before use if you have a medical condition or take medication, and the tablet and gummies labels ask the same if you are pregnant or breastfeeding [4].

So, calcium tablets or calcium and vitamin D3 gummies?

If you want calcium alone at the lowest price, choose the Calcium Tablets 400mg at about 5p a day. If you want vitamin D3 in the same serving and would rather chew, choose the Calcium and Vitamin D3 Gummies at about 33p, and if you want magnesium and zinc alongside, the Calcium Magnesium Zinc tablets at about 6.7p. Whichever you pick, every authorised sentence for calcium quoted above comes with it [1].
