Protein powder and soybean milk powder are two different products with different components and functions. Protein powder is mainly used to supplement protein, and is usually made from protein of animal origin, such as whey protein or soybean protein. The main function of protein powder is to provide protein needed by the body and support muscle recovery and growth. Suitable for people who engage in high-intensity exercise, fitness or need to take extra protein.

Soy milk powder is mainly processed from soybeans, which is rich in plant protein, dietary fiber and some vitamins and minerals. The main function of soybean milk powder is to provide nutrition and energy, which is suitable as a healthy dietary supplement.

Although soybean milk powder contains a certain amount of protein, protein powder usually provides protein more efficiently than soybean milk powder. Therefore, from the perspective of supplementing protein, soybean milk powder may not completely replace protein powder.

Soymilk powder may be a more economical substitute if you don't do high-intensity exercise, or if you need a lot of extra intake of protein. However, if you are looking for a professional athlete with a higher intake of protein, protein powder may be more suitable for your needs.

Whether you choose protein powder or soybean milk powder, you should pay attention to the correct usage and dosage. If you have special health needs or are worried about dietary supplements, it is recommended to consult a doctor or dietitian.
