1) Verifiable facts: the 3 common forms of protein shakes are whey, soy and casein protein. Protein shakes are useful when:

Unverified statements or value claim:
This whole part is unverified: So how can you tell if you’re already getting enough protein? Do the math.
Recreational athletes need 0.5-0.75 grams of protein daily for every per pound of body weight
Competitive athletes need 0.6-0.9 grams per pound
Teenage athletes need 0.8-0.9 grams per pound
Athletes building muscle mass need 0.7-0.9 grams per pound
The maximum amount of protein that most adults can use per day is 0.9 grams per pound of body weight.
So if you’re an adult athlete who wants to build muscle mass, and you weigh about 175 pounds, the most protein you would need per day is 157.5 grams. That sounds like a lot, but one 4-ounce hamburger contains 30 grams of protein, 6 ounces of tuna has 40 grams, and a single ounce of cheddar cheese has 7 grams.
Pretty much everything else is statement or quotes from a doctor.
