Protein is a huge component of nutrition. There are so many different types of protein – isolate, whey, casein, egg, and plant. Proteins are metabolized differently causing you to get hungrier sooner. For example, an isolate will metabolize faster leaving you hungry quicker.
I am a big fan of Trutein protein powder. I like Trutein is because it contains three different kinds of protein-Whey, Casein, and Egg. The three proteins metabolize at different times leaving you feeling fuller longer.
When I consume protein powder, I am a purist- just the powder and water as opposed to using the powder to make smoothies or combining the protein powder with another liquid (milk, almond milk etc). Consistency and texture is very important to me. Trutein powder when added to water is smooth and upon shaking gets frothy so from a consistency perspective it seems like a smoothie.
As far as flavors, initially I bought the Vanilla because from my experience vanilla protein powders taste pretty good (taste is personal preference). Trutein Vanilla was spot on. Recently, I bought Pumpkin Pie flavor as I needed a change and it really does taste like pumpkin pie or even a chai latte. I highly recommend it.
