First of all, tonic is not a necessary choice, but for most office workers and students, it is a wise choice to use tonic because they cannot accurately grasp their daily basic diet. Tonifying can make up for the deficiency of nutrition in diet, and it is relatively convenient to use. At the same time, due to the increasing number of fitness people, more and more brands have entered China, and more and more purchase channels are available.

Personally, I am used to using Saif and Nordic power. The effect and taste are good, and the details vary from person to person.
