Some water-soluble vitamins can have negative side effects, some of which can be deadly, when used in excess. Certain water-soluble vitamins, including vitamin K, have no detectable toxicity and no established UL. Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B5 (pantothenic acid), Vitamin B7 (biotin), and Vitamin B12 are some of these vitamins (cobalamin).

Because of this, care should be given when using any nutritional supplements.

  • Vitamin C: Despite having a low level of toxicity, vitamin C can have adverse effects on the digestive system, including diarrhoea, nausea, cramps, and vomiting.
  • Vitamin B3 (niacin): When used in large dosages as nicotinic acid, niacin can cause liver damage, high blood pressure, stomach discomfort, and visual problems.
  • Vitamin B6 (pyridoxine): B6 overconsumption over an extended period of time can result in severe neurological symptoms, skin lesions, light sensitivity, nausea, and heartburn.
  • Vitamin B9 (folate): Too much folic acid or folate in the form of a supplement can compromise immunological function, impair mental function, and conceal a potentially serious vitamin B12 shortage.

A vitamin overdose can have even more severe effects in people with existing medical issues. Vitamin C, for instance, can induce tissue damage and fatal cardiac irregularities in persons with hemochromatosis, an iron storage condition, despite being unlikely to be toxic in healthy individuals.

  • Vitamin A: Although hypervitaminosis A, or vitamin A toxicity, can develop from consuming vitamin A-rich foods, it’s more commonly linked to supplements. An increase in intracranial pressure, nausea, coma, and possibly death are some of the symptoms.
  • Vitamin D: Weight loss, loss of appetite, and irregular pulse are just a few of the severe symptoms that can result from vitamin D toxicity when taken in large levels. Additionally, it may increase blood calcium levels, which may harm internal organs.
