Another point to remind everyone is that if a large amount of vitamin C is replenished for a long time, once discontinued, it may actually cause the body to be "forced to lack". Why is Effervescent tablet more risky? The reason why Effervescent tablet can produce refreshing "bubbles" while melting in water is that they contain sodium carbonate, sodium bicarbonate and other disintegrants. From the names of these two disintegrants, you can clearly see the presence of the "sodium" element. And sodium is also the main component of table salt. 1. In fact, the sodium content of many Effervescent tablet on the market is surprisingly high. Although different brands of Effervescent tablet contain different amounts, the total amount is 6000-12000 mg/100g. How to understand this quantity?
