Haematinic (Blood Tonic / Iron and Vitamin Supplement)
Last reviewed June 2026
Who is this for?
This is a blood-building tonic that combines iron (ferric ammonium citrate), folic acid, vitamin B12, and other B vitamins along with zinc and copper to help your body produce healthy red blood cells and fight tiredness caused by low blood levels.
Replenishes iron stores and facilitates haemoglobin synthesis by providing ferric iron as a substrate for haem production, whilst B vitamins (B1, B2, B6, B12, folate, nicotinamide) act as essential cofactors in erythropoiesis, energy metabolism, and DNA synthesis; zinc and copper serve as cofactors for enzymes involved in red blood cell maturation and oxidative processes.

For adults, take 2 to 4 teaspoons (10–20 ml) two to three times daily, or as directed on the product label (e.g. Reventin Blood Tonic). You can take it with or after food to reduce stomach upset. Shake the bottle well before use.
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, just skip the missed one and continue as normal. Do not double up to make up for the missed dose.
Buy only from reputable pharmacies — avoid blood tonics sold by roadside vendors as they may be expired or fake. Do not take more than the recommended dose thinking it will build your blood faster, as too much iron can be harmful. If you have been feeling very tired or weak for a long time, see a doctor for a proper blood test rather than self-treating with tonics alone.
Avoid taking this tonic at the same time as tetracycline or ciprofloxacin antibiotics, as the iron can reduce how well they work — space them at least 2 hours apart. Antacids (drugs for ulcer like aluminium or magnesium-based ones) can also reduce iron absorption if taken together. Tea and coffee can reduce how much iron your body absorbs, so avoid drinking them close to your dose.

Is it safe to take Ferric with your other drugs?
This tonic is generally considered safe and often recommended during pregnancy and breastfeeding to prevent low blood, but always confirm the right dose with your doctor or midwife first.
Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot, so avoid leaving it on window sills or inside hot cars. Keep the bottle tightly closed and out of the reach of children.
