Other side effects from too much niacin include: Itchy skin Rapid heartbeat Gout Nausea Vomiting Diarrhea Liver damage Vitamin B12 or Cobalmin Reports suggest that vitamin B12 can cause an allergic reaction, with symptoms such as: Itchy skin Hives Skin rash Tongue swelling Difficulty breathing Bloating Painful stomach Vitamin B7 or Biotin Another B vitamin that may cause an allergic reaction is vitamin B7
No claims are made regarding therapeutic, diagnostic, or biological suitability beyond research use
When you eat, your body breaks nutrients down into fuel, but NAD is what allows that fuel to be converted into ATP, the actual energy currency your cells use
A study mentions that examining its presence in equine urine and plasma discovered that it has possibly been administered to create optimal healing and performance conditions for horses [4]
