Magnesium

An essential mineral with authorised claims — and several forms across the range

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

Magnesium is an essential mineral with specific authorised claims in Europe. This article explains what those authorised claims are, why elemental dosing matters, and how WellsparQ uses different magnesium salts across its range.

This piece summarises magnesium’s biological roles, the exact authorised claim wording that may be used on labels, key forms of magnesium used in WellsparQ products, and how the brand declares elemental magnesium to meet labelling rules. It also flags where claims can and cannot be made based on serving size.

Magnesium is one of the minerals the body genuinely cannot do without. It is a cofactor for hundreds of enzyme reactions, it sits at the heart of energy metabolism, and it helps nerves and muscles do their work. Unlike most ingredients in the WellsparQ range, magnesium is an authorised nutrient: European food law recognises specific, worded health claims for it, and — where a product provides enough — WellsparQ may use them, in the exact authorised wording. This article is therefore evidence-and-claims-led, as a well-established nutrient warrants.

Why the body needs it

An adult body holds roughly 25 grams of magnesium, most of it in bone, with the rest in soft tissue and a small, tightly-regulated amount in blood ^¹. It acts as a cofactor in a very large number of enzymatic reactions — including those that produce and use ATP, the cell's energy currency — and it contributes to nerve transmission, muscle contraction and normal electrolyte balance ^¹. Dietary sources are plant-rich: wholegrains, nuts, seeds, legumes and green leafy vegetables (magnesium sits at the centre of the chlorophyll molecule), which is why a plant-forward diet is a good foundation ^¹².

The nutrient reference value (NRV) used on UK labels is 375 mg. Surveys in several countries suggest a proportion of adults fall short of recommended intakes, which is part of why magnesium is a common supplement ^¹.

The authorised health claims

Because magnesium is authorised, we can state what the claims register permits — attributed to the nutrient, in exact wording, and only where a serving provides at least 15% of the NRV (56 mg) per day. The claims relevant to the WellsparQ range are:

These are permitted statements of nutritional function under retained EU Regulation 432/2012 — not disease claims, and usable only when the dosage condition is met ^³.

What the wider research examines

Beyond the authorised functions, magnesium is heavily studied. Reviews and meta-analyses have examined supplementation in areas such as muscle performance and post-exercise soreness — for example a 2017 meta-analysis in Magnesium Research on magnesium and muscle fitness, and a 2024 systematic review in the Journal of Translational Medicine on muscle soreness across activity types ^⁴⁵. These are reported here as research context; the on-label position rests on the authorised claims above, not on this exploratory literature.

Forms matter — and WellsparQ uses several

Magnesium is always delivered as a salt (bound to another molecule), and the salt affects the elemental magnesium content and how readily it dissolves. WellsparQ deliberately uses a range of forms, and declares the elemental amount:

Declaring elemental magnesium (the actual magnesium content, not the weight of the whole salt) is the honest way to state a dose, and it is what lets the NRV percentages on the label mean something.

How WellsparQ uses it

Source: WellsparQ Supplements Database. The EveningCalm entry is instructive: at 50 mg (13% NRV) it is deliberately below the claim threshold, and the card says so plainly — "included and declared, with no claim made at this level." That is the standard we hold: the claim appears only where the dose earns it.

Suitability and sensible use

Magnesium salts are mineral, not animal-derived, and suit vegan, vegetarian, kosher and halal diets (check the finished product). The most common effect of higher intakes, especially from oxide, citrate or sulphate/hydroxide forms, is a laxative one — loose stools. UK guidance notes that supplemental magnesium at around 400 mg/day or less is unlikely to cause harm for most adults ^². Anyone with kidney impairment, or taking certain medicines (some antibiotics, bisphosphonates), and anyone pregnant or breastfeeding, should speak to a GP or pharmacist first.
