Carbonyl Iron 65 mg + Vitamin C 125 mg | 180 Tablets | WeightWorld

Carbonyl Iron 65 mg + Vitamin C 125 mg by WeightWorld is a dietary supplement in a bottle of 180 tablets, pairing an iron form known for gradual release with the vitamin that raises its absorption. One tablet daily covers both doses. It suits anyone who has tried conventional iron salts and found them heavy on the stomach, and anyone wanting iron stores supported through a simple daily routine rather than two separate tablets.

What is carbonyl iron?

Carbonyl iron is a high-purity elemental iron made of fine iron particles rather than an iron salt bound to an acid, as in ferrous sulfate or ferrous fumarate. The name has nothing to do with carbon monoxide gas; it refers to the manufacturing process. Its defining property is that dissolution depends on stomach acid, so iron is released at a gradual rate instead of the bolus release given by iron salts.

Benefits of iron with vitamin C

• Red blood cell production support: iron is a structural element of the oxygen-carrying haemoglobin molecule.
• Reduced tiredness and fatigue: low iron stores are linked to weaker oxygen delivery to tissue.
• Cellular energy support: iron forms part of the electron transport chain enzymes inside mitochondria.
• Immune system support: iron and vitamin C both take part in immune cell function.
• Raised iron absorption: vitamin C converts iron into the form more readily taken up in the small intestine.
• Collagen formation support: vitamin C is a required coenzyme for maturing collagen fibres.
• Mental focus support: iron availability is tied to oxygen reaching brain tissue.

Active ingredients

• Carbonyl iron 65 mg: high-purity elemental iron with acid-dependent release, supplying the raw material for haemoglobin synthesis.
• Vitamin C 125 mg: ascorbic acid, acting as a reducing agent that keeps iron in its absorbable ferrous state.

How it works in the body

Non-haem iron is absorbed through the divalent metal transporter DMT1 in the cells lining the duodenum, and that transporter accepts only the ferrous, divalent form. This is where vitamin C earns its place: as a reducing agent it converts iron from the ferric trivalent state to the ferrous state, and forms a soluble complex with it that keeps it absorbable in the alkaline environment of the intestine. Once inside the cell, iron passes into the blood through the ferroportin protein, binds transferrin for transport, and is then delivered to bone marrow for haemoglobin synthesis or stored as ferritin. The gradual release of carbonyl iron keeps the concentration of free iron in the gut lumen lower at any given moment.

What sets this formula apart

The difference between carbonyl iron and conventional iron salts is the release mechanism. Ferrous sulfate dissociates quickly and raises free iron concentration all at once, which explains why many people find it heavy on the stomach. Carbonyl iron dissolves at a rate governed by stomach acid itself, so release is staged. Including 125 mg of vitamin C in the same tablet removes the need to take citrus juice alongside the dose. The formula is vegan and non-GMO, the tablet is small, and 180 tablets cover 180 days at one a day.

Who is this product for?

• People with persistent tiredness linked to low iron stores following a doctor's assessment.
• Women of reproductive age who lose iron regularly.
• Vegetarians and anyone whose diet is low in red meat.
• People who tried conventional iron salts and found them hard on digestion.
• Regular blood donors and anyone carrying a high endurance training load.

How to use

One tablet daily of the carbonyl iron 65 mg + vitamin C 125 mg formula, swallowed with a glass of water. Avoid taking it at the same time as tea, coffee or dairy products, since tannins and calcium lower iron absorption. Leaving roughly two hours between the dose and those drinks is the practical arrangement.

Frequently asked questions

What is the difference between carbonyl iron and ferrous sulfate?

Carbonyl iron is a fine-particle elemental iron whose dissolution depends on stomach acid, so it releases gradually, while ferrous sulfate is a salt that dissociates quickly and releases iron all at once. That difference in release rate is why carbonyl iron is described as gentler on digestion.

Why is vitamin C added to an iron supplement?

Vitamin C is a reducing agent that converts iron from its trivalent to its divalent form, the only form the intestinal absorption transporter accepts. Having 125 mg of vitamin C in the same tablet builds the absorption step into the dose rather than relying on an outside source.

When should an iron tablet be taken relative to coffee and tea?

Leave roughly two hours between the iron tablet and tea, coffee or dairy products. Tannins in tea and coffee and calcium in milk bind iron in the gut lumen and lower the amount absorbed.
