Vitamin B Complex supplement
Last reviewed July 2026
Who is this for?
This is a Vitamin B Complex injection that combines five important B vitamins: Vitamin B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), Nicotinamide (a form of Vitamin B3), and Dexpanthenol (a form of Vitamin B5). These vitamins work together to help your body convert food into energy, support your nervous system, and keep your skin, eyes, and blood healthy.
**Vitamin B1 (Thiamine):** Serves as a coenzyme for thiamine pyrophosphate-dependent enzymes involved in carbohydrate metabolism and nervous system function, facilitating energy production and neurotransmitter synthesis. **Vitamin B2 (Riboflavin):** Functions as a precursor for flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), essential cofactors for oxidative-reduction reactions in cellular energy metabolism and antioxidant defense. **Vitamin B6 (Pyridoxine):** Converts to pyridoxal 5-phosphate
Vitamin B deficiency, tiredness and body weakness, poor appetite, nerve problems like numbness or tingling in hands and feet, mouth sores (angular cheilitis), cracked lips, recovery after illness or surgery, nutritional support for people who are not eating well

If you miss your scheduled injection, go to the clinic as soon as you remember. If it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take a double dose.
Always get this injection from a hospital, clinic, or registered pharmacy; do not buy ampoules from roadside sellers or unregistered shops as they may be fake or poorly stored. Make sure the nurse or doctor uses a new, sterile needle and syringe. If you feel any unusual reaction like itching, rash, or difficulty breathing during or after the injection, tell the healthcare worker immediately.
Levodopa (used for Parkinson's disease): Vitamin B6 can reduce its effectiveness, so inform your doctor if you take it. Phenytoin or phenobarbital (used for seizures/convulsions): B vitamins may affect how these drugs work. Alcohol: heavy drinking reduces the absorption of B vitamins and can worsen deficiency, so avoid excessive alcohol.
