The products also states that it helps build strength and endurance, improves sleep, increases energy, and reduces pain.

A liquid diet that works while you sleep is ideal for most everyone. However, the scientific proof that these sorts of collagen diets actually work isn’t yet available. This product depends on the user drinking lots of water and negating their caloric intake after dinner. Anyone who reduces their caloric intake to such extremes is bound to lose some weight, with or without nighttime liquid collagen.
