Vitamin B-Complex supplement
Last reviewed July 2026
Who is this for?
This is a Vitamin B-Complex combination containing four important B vitamins: Thiamine (B1), Riboflavin (B2), Pyridoxine (B6), and Niacinamide (B3), which work together to help your body turn food into energy, support your nerves, and keep your skin, eyes, and blood healthy.
Serves as essential coenzymes for carbohydrate, amino acid, and lipid metabolism by activating key enzymatic pathways (thiamine pyrophosphate for pyruvate dehydrogenase; flavin adenine dinucleotide for oxidative phosphorylation; pyridoxal phosphate for transamination reactions; niacinamide for NAD+/NADH-dependent dehydrogenases), thereby restoring cellular energy production and supporting nervous system function, protein synthesis, and tissue repair in deficiency states.
Vitamin B deficiency, tiredness and body weakness, poor appetite, mouth sores and cracked lips, nerve problems like numbness or tingling, general body weakness during illness or recovery, poor nutrition

If you miss a dose, just take it as soon as you remember. If it is almost time for your next dose, skip the missed one and continue as normal. No need to double up since these are vitamins, not antibiotics.
Buy only from reputable pharmacies; avoid buying vitamins from roadside sellers or open markets as they may be expired or fake. Do not take more than the recommended dose thinking it will work faster, as excess vitamins can cause problems. If you are on TB medication, tell your doctor so they can adjust your B-Complex dose properly.
Levodopa (used for Parkinson's disease): Pyridoxine (B6) can reduce its effectiveness. Certain antibiotics like isoniazid (used for TB treatment) can deplete B vitamins, so your doctor may prescribe B-Complex alongside TB drugs. Alcohol reduces your body's ability to absorb B vitamins, so reduce alcohol intake while using this supplement.
