Yikexin.

1. In terms of quality: The raw materials of Vitamin A and Vitamin D of Yicosin are imported raw materials and are produced by the famous vitamin manufacturer DSM. The capsules are made of high-quality gelatin raw materials produced by Rousselot, France. However, Energy Guard has a lower vitamin content and its raw material sources are not as good as those from major foreign manufacturers.

2. In terms of word-of-mouth: Yikesin is a world-famous vitamin brand with users all over the world and rave reviews, while Energy Guard is an emerging brand and product control is not strict enough, so consumer reviews are good. There are bad and mixed reviews.
