I usually put 30 grams of protein into a post-workout protein shake. Anyway, you need 30 grams of white in a smoothie, no matter what time of day you consume it. I think it is enough to consume 1.2 g / kg of protein a day anyway, because if someone eats a lot more protein, it will be effective for a while, but later the body will get used to it and you will be there in the end. It is also worth keeping an eye out that 70% of the intake of protein is good if it comes from a natural nutrient and only the remaining 30% is taken in with food supplements.
