From the perspective of calcium supplementation, drinking yogurt at night offers more benefits. Because between 12 PM and 2 AM, the human body's blood calcium level is at its lowest, which is beneficial for the absorption of calcium from food. At the same time, there are fewer factors affecting calcium absorption in the body during this period. Although milk also contains a high amount of calcium, the lactic acid in yogurt combines with calcium, making it more effective in promoting calcium absorption. Generally speaking, the best time to drink yogurt is between 30 minutes and 2 hours after a meal.
When drinking yogurt at night, it is important to remember that certain bacterial cultures and acidic substances in yogurt can be somewhat damaging to teeth. You should brush your teeth promptly after drinking it.
