First of all, we must establish a correct concept. The purpose of taking dietary supplements is not to treat diseases, but to treat diseases. We need to follow the doctor's advice. The feeling before and after taking this varies from person to person; If your body is in a state of extreme lack of nutrition, you will feel the effects within 7 days, such as probiotics, vitamin B complex (hair loss, skin luster, smoking and drinking) and so on. If your nutritional status is good, it usually takes 1-3 months to feel obvious changes, to maintain balance and to pursue a better physical condition. You can accept my suggestion and continue to ask questions if you don't understand.
