1. If it's just to keep healthy and smooth muscle lines, it's necessary to supplement protein. Good diet plan and exercise can satisfy the body's demand for protein.
If you want to get better results, such as increasing muscle mass or reducing fat content, you may need extra nutritional supplements. These supplements include protein powder, amino acids, vitamins and minerals.
3. For junior trainers, there is usually no need to supplement. Intermediate trainers can use supplements correctly under professional guidance, such as protein powder. Advanced trainers may need to use more supplements to help them achieve higher training goals.
It should be noted that supplements are not always necessary. Some nutrients can be obtained through food. At the same time, the use of supplements also needs to be carried out under the guidance of doctors or professionals to ensure safety and effectiveness. For the use of any fitness supplement, it is necessary to know its function, risk, correct use and other information, and consult professionals.
