Hello, vitamin C is able to enhance the body's immune system, but generally people with a normal diet can get the amount the body needs from food.

Guidance:

The biggest side effect of long-term oral vitamin C is constipation. So if you have a normal diet, you should still try to get it from food.

Hello

Vitamin C can play a role in whitening, but long-term use of vitamin C tablets is somewhat harmful.

Guidance:

Vitamin C can't be absorbed if you eat too much of it. It is recommended that you eat more fruits and foods that contain Vitamin C. I wish you good health and happiness
