A properly prepared effervescent tablet or powder can allow a large dose of ingredients to be taken in a single serving. The organic food acid combines with the carbonate source to form potassium, sodium, calcium or magnesium salts of the acid and buffers the solution to a normal pH, so it is easy on the stomach. Clinical studies performed on a variety of effervescent products demonstrates that the ingredients penetrate the blood stream within as little as 15 minutes.
