GB Nutrition and Health Claims Register: Minerals

Compiled and maintained by the Wellgard Scientific Editorial Team · Official register version: 19 May 2026 · Page updated: 17 October 2026 · Sources checked on: 16 October 2026

This resource reproduces the authorised nutrition and health claims recorded in the Great Britain Nutrition and Health Claims Register, including the register's wording, conditions of use and supporting references. Compiled from the Department of Health and Social Care's published register, it is a reference for claims authorised for use in England, Scotland and Wales, subject to the applicable legal requirements.

This is Wellgard's reproduction and explanation of official data. It is not a government website, a product approval, or a substitute for assessing the applicable law and conditions of use. The GOV.UK register is the authoritative source.

Northern Ireland continues to follow the EU register under the Windsor Framework; this resource covers Great Britain only. The summaries under each heading, the notes on labels and the lines beginning "In plain terms" are Wellgard's explanation; the register's own text is reproduced in the tables, word for word after the removal of the source file's own HTML wrapper tags.

At a glance

• Source and version: Department of Health and Social Care, Great Britain nutrition and health claims (NHC) register, release of 19 May 2026.
• Jurisdiction: England, Scotland and Wales. Northern Ireland follows the EU register under the Windsor Framework.
• What is included: the authorised health claims for minerals, with the register's conditions of use and Wellgard's notes on what each threshold means.
• Counts in this release: 267 authorised health claims across 91 register headings, 30 nutrition claims, and 2,082 assessed claims that were not authorised (145 of them, which name a commercial product or carry a trade mark or a branded strain code, are left to the GOV.UK file).
• Authorised: assessed, substantiated and placed on the register by regulation; usable only under its conditions of use.
• Assessed but not authorised: a specific wording that was evaluated and refused, with the register's reason; listed on the companion pages.
• On hold: a transitional status for botanical claims submitted in 2008 and never assessed; neither authorised nor rejected (GOV.UK on-hold list).
• Not listed here: a search result, not a finding. A wording absent from these pages has not been judged by anyone, and its absence says nothing about a substance's benefits.
• Nutrition claim or health claim: a nutrition claim says what a food contains ("source of fibre"); a health claim links a food or nutrient to health ("contributes to the normal function of the immune system"). They have separate lists and separate conditions.

How to read the tables

• Heading: the register's own name for the nutrient, substance, food or food category, in alphabetical order, each with a fixed link (for example #vitamin-c). Under it, a Wellgard summary of the count and thresholds, a note on labels, and a link to the Health Insiders article where one exists.
• Claim wording: the authorised text, verbatim. Each row has its own link, built from the heading and the register entry number.
• Register condition (verbatim): the condition of use exactly as the register states it; this is the legal test. Where a condition goes beyond the standard "source of" rule (a daily amount, an audience, a label warning, a food-type restriction), a line beginning "In plain terms" follows it in the same cell: Wellgard's reading, not register text.
• Regulation and entry: the article of the regulation the claim was authorised under (13(1) general function; 13(5) newly developed evidence or proprietary data; 14(1)(a) disease risk reduction; 14(1)(b) children's development and health), the authorising regulation and the register entry number.
• Assessment: the register's short description of the health relationship assessed, and the scientific opinion reference (EFSA Journal: year; volume(issue): article number; or a link to the UK Nutrition and Health Claims Committee opinion).

Reading the tables: register text in the four columns is reproduced exactly; the "In plain terms" lines and the paragraphs under each heading are Wellgard's explanation. Terms such as "source of", "high in" and "nutrient reference value" are defined in the glossary.

Authorised health claims: minerals

Calcium

What this means: Calcium has ten authorised health claims in Great Britain. A food may carry them at 120 mg or more per 100 g (60 mg per 100 ml for a drink), a supplement at 120 mg or more in its daily dose. "High in" needs twice that: 240 mg per 100 g.

What this means on labels: a compliant pack quotes a register wording, for example "Calcium contributes to normal blood clotting", or a close equivalent that keeps the same meaning for the shopper, such as "Calcium supports normal blood clotting". Phrases that go beyond the register for this heading include "builds strong bones", "prevents osteoporosis" or "stops tooth decay", "builds muscle" or "burns fat", "detoxes", "heals your gut" or "cures IBS", and any reference to preventing or treating a disease. The claim belongs to Calcium at the qualifying amount: a pack cannot transfer it to another ingredient or to the product as a whole, and the general rule that a claim is made about the product as sold still applies. Flexibility of wording is explained in the Department of Health and Social Care guidance.

Calcium and vitamin D

What this means: Calcium and vitamin D has two authorised health claims in Great Britain. Each has its own condition of use, set out in words in the table below.

What this means on labels: a compliant pack quotes a register wording, for example "Calcium and vitamin D are needed for normal growth and development of bone in children", or a close equivalent that keeps the same meaning for the shopper. Phrases that go beyond the register for this heading include "builds strong bones", "prevents osteoporosis" or "stops tooth decay", and any reference to preventing or treating a disease. The claim belongs to Calcium and vitamin D at the qualifying amount: a pack cannot transfer it to another ingredient or to the product as a whole, and the general rule that a claim is made about the product as sold still applies. Flexibility of wording is explained in the Department of Health and Social Care guidance.

Chloride

What this means: Chloride has one authorised health claim in Great Britain. A food may carry them at 120 mg or more per 100 g (60 mg per 100 ml for a drink), a supplement at 120 mg or more in its daily dose. "High in" needs twice that: 240 mg per 100 g.

What this means on labels: a compliant pack quotes a register wording, for example "Chloride contributes to normal digestion by production of hydrochloric acid in the stomach", or a close equivalent that keeps the same meaning for the shopper, such as "Chloride supports normal digestion by production of hydrochloric acid in the stomach". Phrases that go beyond the register for this heading include "detoxes", "heals your gut" or "cures IBS", and any reference to preventing or treating a disease. The claim belongs to Chloride at the qualifying amount: a pack cannot transfer it to another ingredient or to the product as a whole, and the general rule that a claim is made about the product as sold still applies. Flexibility of wording is explained in the Department of Health and Social Care guidance.

Assessed, not authorised

The register also records 2,082 wordings that were assessed and not authorised, with the reason in each case: most often that a cause and effect relationship was not established on the evidence assessed. A refused wording may not be used in Great Britain, and nor may a wording likely to mean the same to the consumer. That is a judgement on a wording, not a finding about a substance; and it is a different status from "on hold" (see the glossary). The refused wordings are listed verbatim, with the register's reason, on six companion pages arranged by the first letter of the register heading: A to B, C to F, G to K, L, M to P, Q to Z.

What is not on these pages

Claims on hold. Around 2,000 claims for botanicals (plant ingredients such as turmeric, ginseng, maca or green tea) were submitted under Article 13 in 2008 but were never assessed, because the European Commission paused the botanical assessments in 2010 and has not resumed them. Great Britain inherited that position. These claims are neither authorised nor rejected; under the transitional rules they may continue to be used in Great Britain under the responsibility of the business, provided they comply with the general requirements of the regulation, until a decision is taken. An on-hold wording is not evidence that a benefit has been proven, and its status is not a verdict against the plant either; it is a statement about where the claim sits in the process. A later phase of this resource will list the on-hold wordings for the botanicals Health Insiders covers. Two articles already explain how the hold works in practice: What are the benefits of turmeric? and What is maca root good for?

Proprietary-data claims. Six authorised claims were authorised on the basis of proprietary data under Article 13(5), which gave the applicant exclusive use for five years. They are marked in the register with an asterisk and listed in its annex with the applicant and the expiry date of the restriction. The claims are included on these pages; the annex's commercial details are not.

How the thresholds are worked out

Most vitamin and mineral claims may be used only for a food that is at least a "source of" the nutrient. The Annex to Regulation (EC) No 1924/2006 defines "source of" a vitamin or mineral as a significant amount, and Annex XIII of Regulation (EU) No 1169/2011 sets that amount at 15% of the nutrient reference value per 100 g or 100 ml, 7.5% per 100 ml for a drink, or 15% per portion where the pack contains a single portion. For a food supplement the significant amount is 15% of the nutrient reference value in the daily dose recommended on the label (Annex XIII, Part A, point 2). "High in" is twice the "source of" amount (Annex to Regulation 1924/2006).

The thresholds in the summary lines are those percentages applied to the nutrient reference values in Annex XIII, Part A, point 1. Where a register heading has no nutrient reference value (fibres, fatty acids, foods and other substances), the condition is quoted in words from the register instead.

Register text comes from the Department of Health and Social Care's spreadsheet as published on GOV.UK (19 May 2026 release), read cell by cell; nothing in a register column is edited. Our explanatory text is checked against the compliance guidance and the guidance on flexibility of wording.

Glossary

Source of

For a vitamin or mineral, a significant amount: 15% of the nutrient reference value per 100 g or 100 ml, 7.5% per 100 ml for a drink, or 15% in the daily dose of a supplement (Regulation 1169/2011, Annex XIII; Regulation 1924/2006, Annex). For fibre, 3 g per 100 g or 1.5 g per 100 kcal. For protein, at least 12% of the food's energy.

High in

Twice the "source of" amount for vitamins and minerals; for fibre, 6 g per 100 g or 3 g per 100 kcal; for protein, at least 20% of the food's energy (Regulation 1924/2006, Annex).

Significant amount

The quantity of a vitamin or mineral that justifies naming it in nutrition labelling, and the quantity "source of" refers to (Regulation 1169/2011, Annex XIII, Part A, point 2).

Per daily portion or daily dose

For a food supplement, amounts are judged against the daily dose recommended on the label, not per 100 g (Annex XIII, Part A, point 2; Regulation 1924/2006, Article 5).

Nutrient reference value (NRV)

The daily reference amounts for vitamins and minerals used on labels and in the "source of" test; for example 80 mg for vitamin C and 800 mg for calcium (Regulation 1169/2011, Annex XIII, Part A, point 1).

"The claim may be used only for food which"

The opening words of most conditions of use: the test is applied to the food as sold, not to an ingredient on its own, and a food that does not meet it cannot carry the claim (Regulation (EU) No 432/2012).

Omega-3 conditions

"Source of omega-3 fatty acids" means at least 0.3 g of ALA per 100 g and per 100 kcal, or at least 40 mg of EPA plus DHA per 100 g and per 100 kcal; "high" doubles those amounts (Regulation (EU) No 116/2010, adding to the Annex of Regulation 1924/2006). Several DHA and EPA claims also require a stated daily intake and, for the risk-reduction claims, a daily amount of 3 g or 2 g with a warning not to exceed 5 g.

Plant sterol and stanol conditions

The cholesterol claims require a daily intake of 1.5 g to 3 g of plant sterols or stanols, information on the effect size, and the labelling set by Regulation (EC) No 608/2004; the conditions were amended by Regulation (EU) No 376/2010 and Regulation (EU) No 686/2014.

Dental and sugar conditions

The tooth mineralisation and blood glucose claims for sugar replacers apply where sugars in a food are replaced by the named sugar replacers so that the food does not lower plaque pH below 5.7, or where the food qualifies as "sugars free"; the chewing gum claims require sugar-free gum chewed for at least 20 minutes after eating or drinking (Regulation 432/2012).

Fibre thresholds

"Source of fibre": 3 g per 100 g or 1.5 g per 100 kcal. "High fibre": 6 g per 100 g or 3 g per 100 kcal (Regulation 1924/2006, Annex). Fibre claims in the register name the fibre and usually require the "high fibre" level from that fibre.

On hold

Botanical claims submitted under Article 13 in 2008 that the European Commission paused in 2010 and that Great Britain inherited unassessed. Neither authorised nor rejected; their continued use is a transitional arrangement under the responsibility of the business, subject to the general requirements of the regulation (GOV.UK on-hold list).

Not listed here

A wording that appears on none of these pages has not been assessed in either direction. It is a search result, not a judgement on the substance.

Frequently asked questions

Can a label say "high in magnesium" and make a magnesium claim?

Yes, if the food meets both conditions: "high in" means twice the "source of" amount (112.5 mg of magnesium per 100 g against 56.25 mg for "source of"), and the health claims may be used for any food that is at least a "source of" magnesium.

Can a multivitamin and mineral make every mineral's claim?

Only for the minerals present at a significant amount in the daily dose, 15% of the nutrient reference value, and only with the register wording for each. A mineral below that level cannot carry its claim however it is described.

Does a calcium claim cover bone density or osteoporosis?

The Article 13 claims cover the maintenance of normal bones and teeth. Osteoporosis is a disease, and only the separate Article 14 risk-reduction claims for calcium, and for calcium with vitamin D, may mention bone mineral loss in post-menopausal women, under their own conditions; they are listed under those headings.

Is "electrolyte balance" an authorised claim?

Yes, for magnesium: "Magnesium contributes to electrolyte balance", at the "source of" level. Carbohydrate-electrolyte solutions have their own claims, listed on the other substances page, with conditions on carbohydrate and sodium content.
