It is not good to drink vitamin C effervescent tablets every day. Most of the vitamin C effervescent tablets on the market are single tablets of 1 g. This dose can be soaked in warm water or cold water every day, and it is best not to take it for more than 5 days. Some people think that vitamin C effervescent tablets, like some antibiotics, will achieve better efficacy by doubling the dose for the first time, but it is not necessary. Taking too much will cause waste, increase the burden on the kidneys, and some will accumulate in the body to produce adverse reactions, which are harmful to the body. Don't take vitamin drugs as daily nutrition.
