Vitamin B complex supplements are generally safe when taken in recommended doses. However, excessive intake can cause side effects. High doses of B3 (niacin) may cause flushed skin, while excessive B6 can lead to nerve toxicity. People with certain health conditions, such as liver disease or peptic ulcers, should use caution. It's important to note that Vitamin B complex can interact with certain medications, including chemotherapy drugs and anticonvulsants.
Keep out of reach of children and do not consume if pregnant or breastfeeding.
Food supplements should not be used as a substitute to a healthy diet and lifestyle.
