Notes:

1. It should be emphasized that boiling water must not be used for brewing, because protein is composed of polypeptides. If it encounters high temperature and strong acid, It will expire after a while and complete the loss of nutritional value. Therefore, cold or warm water should be used to brew protein powder.

2. It is not advisable to drink protein powder on an empty stomach. Do not drink too much at one time. Eat less often and try not to drink protein powder in the morning.

3. Control the addition of condiments: Whey protein can be added to a variety of foods. If you like sweet food, you can add sugar, and if you like salty food, you can add salt, but you can't add too much. Because excessive intake of sugar and salt is bad for human health.
