Iron Complex · Biocare | 90 capsules

Why we chose this

Biocare's Iron Complex is provided as iron citrate, an organic form that is significantly better tolerated. It is formulated alongside three co-factors chosen to support its absorption and use: vitamin C — which converts iron from its ferric (Fe³⁺) to its ferrous (Fe²⁺) form, the form the body absorbs — vitamin B2 (riboflavin), which contributes to normal iron metabolism, and malic acid, an organic acid found naturally in fruit that creates a mildly acidic environment in the stomach to support iron solubility. Designed as a simple, streamlined option, it supports a wellness-focused approach with a minimal formula produced to high quality standards.

Who is this formula for?

• Adults who want a daily iron supplement with a gentle, stomach-friendly iron form and co-factors for absorption.
• People who have previously found standard iron sulphate tablets difficult to tolerate due to constipation, nausea or stomach upset.
• Vegetarians and vegans, who consume only non-haem iron from plant sources, which has lower absorption rates than the haem iron found in meat and fish.
• Women of reproductive age, who have higher iron requirements due to menstrual blood loss.
• Adults with low dietary iron intake due to restricted eating patterns, high-fibre diets or avoidance of red meat.

Frequently asked questions

Why is iron citrate gentler than iron sulphate? Iron sulphate is an inorganic iron salt. In the digestive tract, it releases free iron ions that can react with the intestinal lining via Fenton chemistry — producing reactive oxygen species that cause local irritation. This is the mechanism behind the constipation, nausea and stomach cramping that many people experience with standard iron tablets. Iron citrate is an organic salt in which the iron is bound to citrate ions. It is less reactive in the gut, releases iron more gradually, and is substantially better tolerated by most people. It is the preferred form for anyone who has experienced side effects with other iron supplements.

What role does vitamin C play in iron absorption? Including vitamin C in an iron supplement is one of the most evidence-supported strategies for improving non-haem iron uptake. The 100 mg of vitamin C in each capsule provides this benefit as part of the formula's design.

Why is vitamin B2 included in an iron supplement? Including B2 in this formula addresses iron metabolism at a cellular level, not just at the point of intestinal absorption.

What does malic acid do in this formula? Malic acid is an organic acid naturally present in fruit. In this formula it acts as an acidulant — contributing a mildly acidic local environment in the stomach that supports iron solubility before absorption. Iron is significantly more soluble under acidic conditions. This is particularly useful for older adults and others with reduced stomach acid production.

Does iron affect the absorption of other minerals? Yes. Iron competes with certain other divalent minerals — particularly zinc and calcium — for absorption through intestinal transport channels. Taking iron at the same time as a calcium supplement, a zinc supplement, or calcium-rich foods (dairy products) can reduce the amount of each that is absorbed. For best results, take this iron supplement at a separate time of day from other mineral supplements and avoid taking it with dairy or very high-calcium foods. Tea and coffee can also inhibit iron absorption when consumed at the same meal.

Is this product suitable for vegans? Yes. All ingredients are vegan, including the capsule shell (HPMC, vegetable cellulose).

How long does one bottle last? At the recommended dose of 1 capsule per day, one 90-capsule bottle provides 90 days' supply — three months.
