It's protein...don't see why not unless it says to use while preggers.
I use to tke them before i found out i wuz pregnaunt. But thn i stopped because protein shakes aren't good to take while ur pregnaunt cause it might fill u up bt u are nt giving the baby the right foods it need . Whn u tke the shake u cannot eat 1 hr aftr nor before u tke it and that makes u full its like u ate a meal it might be healthy for u but nt for the baby. The doctor told me to hold back on it until i have the baby. So dnt take it dnt do it jst for ur self do it fr the baby.
I was always told just no creatine....
I would also use the whey protein as like a drink with a meal to supplement what I was eating.
If you add fruit or veggies to the protein powder then there's nothing wrong it and you still get nutrients.
