Calcium

The body’s most abundant mineral — the accounting, not the advertising

All articles checked for accuracy against the GB NHC Register and all sources have citations with verified links to their relevant studies.

Calcium is the body’s most abundant mineral and the one most people can name a role for. This page explains where calcium lives in the body, how much people commonly need, and how WellsparQ lists it in a product — without making any unauthorised benefit claims.

This article summarises the basic nutrition science of calcium: its distribution in the body, dietary reference levels used in the UK and EU, common food sources and a note on high supplemental intakes. It also shows how WellsparQ declares calcium in its formula and explains why no health-benefit wording appears here.

Calcium is the most abundant mineral in the human body, and one of the very few that most people can name a job for without prompting. It is the mineral we associate with bone and tooth, with milk and leafy greens, with the word "structure". It appears in one WellsparQ formula, declared to the milligram like everything else. This page sets out what calcium is and what it does in the body, told as plain nutrition science — and, deliberately, without dressing any of that up as a product promise. The reason for that restraint is explained at the end.

Where it sits in the body

An adult carries roughly a kilogram or more of calcium, and the overwhelming majority of it — around 99% — is held in the bones and teeth, where, combined with phosphate, it gives the skeleton its hardness and structure ^¹². The small remaining fraction circulates in the blood and soft tissues, where it takes part in ordinary physiological processes. The skeleton also acts as the body's calcium reserve: when blood calcium runs low, the body draws on bone to keep circulating levels steady, which is one reason a lifetime's dietary supply matters ^².

This is neutral physiology — the kind of description you would find in any nutrition textbook or government fact sheet. It is not, and on this page must not become, a claim that a WellsparQ product does any of these things for you.

How much, and from where

In the United Kingdom, the reference figure is straightforward. The NHS advises that adults aged 19 to 64 need 700 mg of calcium a day, and that most people should be able to get all of it from a varied diet ^¹. The European Food Safety Authority, working across the EU, set slightly higher population reference intakes — for example 1,000 mg/day for younger adults still laying down bone, easing to 950 mg/day for older adults — reflecting the different methods the two bodies used ^³. The US Institute of Medicine figures, summarised by the NIH Office of Dietary Supplements, sit in a similar band of 1,000–1,200 mg/day for adults ^². The exact number varies with age, sex and the reference body; the shared message is that calcium is a mineral needed in gram-scale daily amounts.

The richest everyday sources are familiar: dairy such as milk, yoghurt and cheese; fortified plant milks; tofu set with calcium; tinned fish eaten with the soft bones, such as sardines; and some green vegetables including kale and pak choi ^¹². Vitamin D matters alongside it, because the body needs adequate vitamin D to absorb calcium efficiently from food ^¹².

There is an upper end, too. The NHS notes that taking high doses of calcium supplements — more than 1,500 mg a day — could cause stomach pain and diarrhoea, which is a reason to treat supplemental calcium as a top-up to diet rather than a substitute for it ^¹.

How WellsparQ declares it

Calcium appears in a single WellsparQ formula, stated to the tenth of a milligram.

Source: WellsparQ Supplements Database. As with the rest of the range, the formula is built on a plant base in a plant-cellulose capsule and is suitable for vegetarians and vegans, and kosher and halal approved. That 362.6 mg is a little over half the NHS daily reference figure of 700 mg — a meaningful contribution on paper, but one that only makes sense read against the calcium a person already gets from food.

Why this page carries no benefit line

Calcium is unusual among the ingredients in this knowledge base: unlike a botanical or a fatty acid, it is an authorised mineral, and it does have permitted health claims in the retained EU Register of nutrition and health claims — for example the well-known wording that calcium is needed for the maintenance of normal bones, and related claims assessed by EFSA ^³⁴⁵. In principle, a calcium product can carry one of those authorised lines.

The catch is procedural but strict. A health claim may only be used in its exact authorised wording, and for this batch no approved calcium claim text was supplied to us in the claims dataset. Rather than paraphrase, guess, or reconstruct the permitted wording from memory — any of which risks a non-compliant label — this page states none. The physiology above is given as background science, not as a benefit of Workout Recovery Matrix. When the exact authorised wording is provided, a compliant benefit line can be added; until then, the honest and safe course is to defer. That fits the quiet WellsparQ standard anyway: say what is in the capsule, to the milligram, and let the claim wait for its correct words.
