How it works

Replenishes essential cofactors for haemoglobin synthesis and oxygen transport by providing iron as a substrate for ferritin formation and haeme synthesis, while B vitamins (B12, folate, B6) activate enzymes critical for DNA synthesis and red blood cell maturation. Restores metabolic function and energy production through B-vitamin-dependent enzymatic pathways in the citric acid cycle and amino acid metabolism.

What to watch out for

Buy from reputable pharmacies. Products like Haepler Blood Capsules, Labvite Drops, or Labvite Multivitamin Syrup are trusted Nigerian brands. Do not give iron tablets meant for adults to children, as iron overdose can be life-threatening in small children. If your stool turns dark or black, do not panic: this is a normal effect of iron and not a sign of danger.

Common Side Effects

stomach upset or mild belly pain

Serious Side Effects

Severe stomach pain or vomiting blood: go to the hospital immediately. Allergic reaction such as swelling of the face

Drug Interactions

Avoid taking this supplement with tetracycline or ciprofloxacin antibiotics as iron reduces how well they work, so space them at least 2 hours apart. Tea, coffee, and milk can block iron absorption, so avoid them around the time you take your dose. Antacids like magnesium trisilicate also reduce iron absorption if taken together.
