Answer
Hello, VC effervescent tablets are made from vitamin C, citric acid, sodium bicarbonate, and glucose. Long-term oral intake of high doses of vitamin C can bring some side effects, possibly causing nausea and diarrhea. Artificially raising vitamin C levels can also affect the absorption of other vitamins, leading to deficiencies. It is recommended to eat more fresh fruits and vegetables, which is the most natural and healthiest lifestyle. Generally speaking, 30 mg per day is sufficient to meet metabolic needs, 100 mg is already a pharmacological dose, and when taking vitamin C effervescent tablets for a cold, it is best to do so once a day for 3-5 days, and not to take them long-term.
