Iron

The mineral that carries oxygen — essential, and easy to get wrong in either direction

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

Iron is the mineral most people recognise for carrying oxygen in the blood. It is essential, and both deficiency and excess matter for safety and labelling.

This article explains what iron does in the body, the two dietary forms and how absorption differs, recommended intake guidance used in the UK/EU, and how WellsparQ declares iron on its product labels. It also explains why no benefit claim appears on this page.

Iron is the mineral most people can name a job for: it carries oxygen in the blood. It sits at the centre of haemoglobin, the protein in red blood cells that picks up oxygen in the lungs and delivers it around the body. It is genuinely essential, one of the more common dietary shortfalls worldwide, and — unusually among minerals — one where excess is a real hazard as well as deficiency. That double-edged character shapes everything about how it should be used and labelled. This page sets out what iron does, how much is needed and from where, and how WellsparQ declares it, as plain nutrition science, with the reason for the page's restraint at the end.

What iron does

Most of the body's iron is in haemoglobin in red blood cells, with more in myoglobin in muscle and a working reserve stored as ferritin ^¹². Its oxygen-carrying role is why iron shortfall shows up as tiredness and, when severe, as iron-deficiency anaemia ^¹. Iron is also part of enzymes involved in energy metabolism and other processes ^². This is neutral physiology, and on this page it stays background science rather than a product benefit.

Two kinds of dietary iron

Diet supplies iron in two forms, and the difference matters for anyone eating plant-based.

Non-haem iron — the form in plant foods and in most supplements, including the plant-based WellsparQ range — is absorbed less readily, but its uptake is improved by vitamin C eaten in the same meal and reduced by tannins in tea and coffee and by some other compounds ^². This is ordinary nutrition science, and a practical reason plant-based eaters pay attention to iron.

How much, and from where

UK guidance sets iron needs at about 8.7 mg a day for adult men and women over 50, and a higher 14.8 mg a day for women aged 19–50 to cover menstrual losses ^¹. The EU nutrient reference value used for labelling is 14 mg ^³. Good dietary sources include pulses, wholegrains, nuts, dried fruit, fortified breakfast cereals and dark green vegetables, alongside meat and fish ^¹².

The caution at the top end is important and specific. The NHS notes that high doses of iron can cause constipation, nausea and stomach upset, and that very high doses can be fatal, particularly for children — accidental iron overdose is one of the leading causes of poisoning deaths in young children, which is why iron-containing supplements must be kept well out of their reach ^¹².

How WellsparQ declares it

Iron appears in several WellsparQ formulas, stated to the tenth of a milligram, in plant-based (non-haem) form.

Source: WellsparQ Supplements Database. As with the rest of the range, the amounts are stated exactly, and the iron is non-haem and suitable for vegetarians and vegans. Because iron is a mineral where more is not better, the presence of iron across several products is a reason to be mindful of totals for anyone taking more than one.

Why this page carries no benefit line

Iron is an authorised mineral: unlike a botanical, it does have permitted health claims in the retained EU Register — for example the well-known wordings that iron contributes to normal formation of red blood cells and haemoglobin, to normal oxygen transport, and to the reduction of tiredness and fatigue, all assessed by EFSA ^³. In principle an iron product meeting the dose condition can carry one of those authorised lines.

The catch is procedural but strict. A health claim may be used only in its exact authorised wording, and for this batch no iron claim text was supplied in the claims dataset. Rather than paraphrase or reconstruct the permitted wording — either of which risks a non-compliant label — this page states none. The physiology above is background science, not a benefit of any named product. When the exact authorised wording is provided, a compliant benefit line can be added to any SKU that meets the dosing condition; until then, the honest course is to defer.
