Secondly, plant protein powder is mostly used for health care, which has no obvious effect on fitness and weight gain, especially on weight gain.
You can try to buy whey protein powder, also called muscle protein powder. Choosing more calories will help to gain weight, and the dosage will be more than now. But I don't suggest that the burden on your heart, kidneys and liver is aggravated, which is not conducive to long-term development.
The best way to gain weight is to eat healthily, ensure three meals on time, and improve digestion and absorption function. Protein powder can continue to be used. If you find yourself unwell, you should reduce it (take a lot of whey protein).
