Indications
Cobalt Gluconate is a source of the trace element cobalt. It is found in some iron, vitamin and blood tonic combinations used to support red blood cell formation in iron deficiency and nutritional anaemia, alongside iron, folic acid and vitamin B12. It is not used on its own as a treatment.
How It Works
Cobalt is the central part of vitamin B12 (cobalamin), which the body needs to make healthy red blood cells and keep nerves working. The human body cannot make vitamin B12 from free cobalt, so in people the real benefit comes from vitamin B12 itself; cobalt salts were traditionally added to blood tonics to support blood formation. Gluconate is a mild carrier that helps the mineral dissolve and be absorbed.
Dosage and Administration
Cobalt gluconate is present in very small amounts in combination products. Take the product as directed on the label or by your doctor, usually after meals. Do not take more than recommended and do not use separate cobalt supplements.
Interactions
Combination iron products can reduce absorption of some antibiotics (Tetracyclines, Ciprofloxacin and other quinolones), Levothyroxine and bisphosphonates; keep a gap of at least 2 hours. Antacids and tea can lower iron absorption. Avoid taking several mineral supplements together without advice.
Contraindications
Do not use if you are allergic to cobalt or any ingredient. Avoid in conditions with iron overload (haemochromatosis), anaemia not caused by iron or nutritional deficiency unless advised by a doctor, and in people with heart muscle disease or thyroid enlargement.
Side Effects
At the small amounts in tonics, side effects are uncommon. The combination products may cause nausea, stomach upset, constipation, diarrhoea or dark stools (from iron). Excess cobalt over time can cause skin rash, thyroid problems and heart muscle damage.
Get urgent medical help if you have signs of a serious allergic reaction (swelling of face or throat, difficulty breathing), chest pain, a very fast or irregular heartbeat, or severe stomach pain with vomiting.
Pregnancy and Lactation
Iron and vitamin combinations are often used in pregnancy, but use any product containing cobalt only on a doctor’s advice, and do not take extra cobalt supplements during pregnancy or breastfeeding.
Precautions and Warnings
Keep to the dose on the label and do not combine several tonics. Have your anaemia properly diagnosed, as some types need different treatment. Use with caution in kidney disease. Keep iron-containing products away from children, since iron poisoning is dangerous for them.
Overdose
Overdose of a combination tonic is mostly dangerous because of the iron content, especially in children: vomiting, stomach pain, diarrhoea, drowsiness and shock. Too much cobalt can affect the heart, thyroid and nerves. Seek emergency medical help immediately.
Therapeutic Class
Mineral supplement (trace element) in haematinic preparations.
