The best time of day to take collagen is in the morning when you wake up on an empty stomach and in the evening before you go to bed. Ingesting collagen on an empty stomach facilitates the absorption of collagen. And after collagen enters the body, it is eventually transformed into amino acids through the decomposition of the digestive tract, which can increase the raw materials for protein synthesis in the body to a certain extent, and a small portion may be involved in collagen synthesis to improve the texture of the skin. It is recommended to consume it twice a day, in the morning and evening on an empty stomach, to effectively avoid waste and loss. When taking collagen, it can also be combined with a topical moisturizing cream to enhance the effect. However, collagen is a health food that does not act as a cure and does not differ much from the role of ordinary protein in the diet. So a balanced and healthy diet is more useful than taking health supplements. It is important to note that after ingesting collagen, individuals may have slight diarrhea, which is usually normal, and if the diarrhea symptoms are more serious, it is not recommended to continue eating collagen.
