IRONCYCLEN® liquid iron supplement for horses

IRONCYCLEN Liquid contains iron, copper and cobalt to supplement diets which may be deficient in these essential minerals. Racing, training and other forms of hard exercise increases the requirement for iron.

IRONCYCLEN is a specially formulated supplement to maximise haemoglobin and red blood cell production which helps improve the oxygen carrying capacity of the blood for peak performance.

The highly palatable molasses flavoured liquid formulation contains:

  • Three forms of iron for maximum absorption
  • Organic iron aminoates which eliminate gut irritation
  • Co-factors of copper and cobalt essential to incorporate iron into haemoglobin


  • High performance horses – Training and competing are added stresses which increase the demand for iron.
  • Horses who have experienced significant blood loss: e.g. surgery, stomach ulcers, parasite burdens, lung bleeders.
  • Animals in training prone to low blood counts and anaemia


  • Supports improved blood counts – Only 15-18% of the iron in the feedstuffs of the average horse’s diet is absorbed.
  • Formulated for maximum absorption – IRONCYCLEN contains 3 forms of iron which are readily absorbed by the gut and are generally of a higher quality than the regular iron used in many other supplements.
  • Essential balance of co-factors – Copper and cobalt are essential for red blood cell and haemoglobin production. Without these co-factors, even with high levels of iron, the horse will still be unable to produce optimal amounts of red blood cells.
  • Liquid formulation – The unique formulation makes IRONCYCLEN easy to mix into feed or administered as directed by a veterinarian.


Each litre contains:

  • Iron (as ferrous sulfate heptahydrate) 8.2 g
  • Iron (as ferrous bisglycinate HCL) 200 mg
  • Iron (as ferric ammonium citrate) 840 mg
  • Copper (as cupric sulfate pentahydrate) 15.1 mg
  • Cobalt (as cobalt sulfate heptahydrate) 4.0 mg


  • Horses (450 - 500 kg):

    45 - 75 mL daily in feed or as directed by a veterinary surgeon.

  • Performance horses

    • Early Training

      Maximum of 75 mL daily in early training for the first 6 weeks.

    • Hard Training

      Give 45 mL daily in a “3 days on, 3 days off” routine while in hard training, increasing to a maximum of 75 mL daily if required.

      “Booster” courses of FBC BLOODFOOD® at key training times will stimulate the bone marrow so that it can respond to the increased demand for more cells.

    • Breeding horses

      45 – 75 mL daily in a “3 days on, 3 days off” routine.

    • Iron Deficiency Anaemia

      45 – 75 mL daily until anaemia corrected (usually 14 - 28 days) or as per veterinary advice.

Tying-up in Horses

Tying-up in Horses

Muscle cramps and tying up are common in performance horses after exercise. Read on for tips on prevention and treatment.

  • Can I give too much iron?

    Too much iron can cause a degree of gut ache. The forms of iron in IRONCYCLEN are less likely to cause this, however if there is too much iron in the diet the gut simply closes the gate preventing excessive absorption.

  • Why do we use less injectable iron these days?

    Injecting iron carries with it the risk of producing anaphylactic shock (severe allergic reaction) and bypasses the body’s regulatory mechanisms.

  • Does calcium supplementation affect iron absorption?

    High calcium supplementation can cause a reduction in iron absorption and therefore in these circumstances iron supplementation would be beneficial.

  • What is Anaemia?

    Anaemia is a low red blood cell count or a low PCV (packed cell volume) or a low Haemoglobin reading or a low MCHC (mean corpuscular haemoglobin concentration) or low MCH (mean corpuscular haemoglobin). Any of those factors or all of them are termed anaemia.

  • How can I tell if my horse is anaemic?

    A blood sample is the only way to definitively tell if your horse is anaemic but some of the clinical signs are:

    • Decreased performance due to a lowered oxygen carrying ability.
    • Poor recovery from exercise and excessive blowing
    • Lack of stamina, poor finishing ability and general lethargy
    • Swelling of lower legs and a rough dull coat,
    • Pale mucous membranes may also be noticed such as the horse's gums appearing paler than usual.

  • Why doesn’t IRONCYCLEN contain Vitamin C?

    Vitamin C is not absorbed well in horses and iron and copper in solution rapidly destroys it. Horses can make their own vitamin C.
