The risks of overusing supplements – From B12 to Iron: Vitamin supplements that may do more harm than good, says health expert

Vitamin B12 is essential for maintaining brain function, the nervous system, and red blood cell production. It is typically found in animal-based foods like meat, fish, eggs, and dairy. Dr. Moore, however, warns against using synthetic B12 supplements like cyanocobalamin, as it contains cyanide, which requires detoxification by the body. Instead, he recommends methylcobalamin, a safer and more bioavailable form. While vitamin B12 is generally safe in the right amounts, overuse may cause nausea, dizziness, skin reactions, or even more serious conditions like irregular heartbeats. It’s best to consume vitamin B12 naturally through food or opt for methylcobalamin supplements.
