Questions about this ingredient

  • QDoes taking a lot of Vitamin C accumulate in the body?

    Ascorbic acid (Vitamin C) is a water-soluble vitamin, so taking more than the necessary amount usually results in excess being excreted in urine. However, consuming a large amount at once can cause stomach discomfort or diarrhea, and if you have a history of kidney stones, please consult a physician before taking high doses.
