Protein powders come in various forms.
The three common ones are whey, soy, and casein protein. “Whey is the most commonly used, because it’s a water-soluble milk protein." It’s also a complete protein, so it’s got all those advantages. (Complete proteins contain all nine of the amino acids necessary for human dietary needs.) People who are vegan may prefer plant based protein
When do you need protein:
1. When you are growing - A teenager needs more protein to fuel his workouts because his body is still growing and uses more protein in general
2. When you are starting a program- If working out is new to you and you’re trying to build muscle, you’ll require more protein than you normally would
3.When you are increasing your workouts- If you normally work out for half an hour a few times a week, but now you’ve decide to train for a half-marathon, your body will need more protein
4.When you are recovering from an injury- Athletes with sports injuries frequently need more protein to help them heal
5.If you are going vegan or are vegan- People who pursue a vegan or vegetarian lifestyle eliminate a number of common protein sources from their diet, including meat, chicken, and fish, and sometimes dairy and eggs as well
