VC is usually taken once a day, and I take three tablets at a time. And VE is once a day, two tablets at a time. One bottle of collagen drink a day, if it is collagen tablets, it is usually 6 capsules a day. Collagen drink is best to drink after meals, because it contains vitamin C, which is more suitable for eating after meals. In addition, because VC is water-soluble, it can be eaten separately, and the absorption effect is not good if you eat too much at one time.
