Protein Sources

One of the decisions you as the consumer have to make is what types of protein source you want for your protein powder. With so many to choose from it can be slightly overwhelming. But think about your goals and what you want most out of a good powder to really maximize the effects so your gains never falter with many types of protein.

Whey Sources

  • Whey Isolate

A more filtered form of whey, this will limit the amount of carbs and fat so you get little to none. An increased and almost pure source of protein, this is a great kind to keep on that lean muscle while looking to lose weight (4).

  • Whey Concentrate

This form gives you a healthy ratio of macronutrients while still pumping you with a large amount of protein. This is a great choice for those bulking up and looking for an increase in strength and size (5).

Non-Diary Sources

  • Pea Protein

A great plant-based option from yellow peas, pea protein offers a complete profile of essential amino acids (EAAs) and will give you great benefits to lean muscle growth and recovery.

  • Brown Rice Protein

With a high amount of BCAAs, this will really give you a great boost to lean muscle growth and recovery. A source that tends to not have any irritants, it offers a clean source of protein (6).

  • Soy Protein

Another source with a complete profile of amino acids and protein per serving, this source is great for fueling muscle protein synthesis. It does work best when paired with other sources of protein.

Other Non-Dairy Sources

  • Chia Seeds
  • Hemp
  • Sunflower Seed
  • Pumpkin Seed
  • Sprouts
