You may want to read back to our original post on whey protein concentrate, and then check out our post on whey protein types, which contains information on all three whey protein types: concentrate, isolate and hydrosylate.
Whey Protein Concentrate vs Isolate:
As noted in the above articles, concentrate and isolate have a few key differences
and i’ll outline the key pros and cons of each:
Whey Protein Concentrate:
Pros:
- Cheaper than isolate
- Contains carbohydrates, great for energy for a morning shake or longer endurance workout
- Slower release into blood stream so better at appetite suppression for those looking to take advantage of the natural weight loss and fat burning benefits of whey protein powder
- Less processed so generally higher levels of antioxidants and essential amino acids available
Cons:
- Higher caloric content
- Lower protein by weight, ie. contains more carbohydrates and fat
- Much higher levels of lactose
Whey Protein Isolate:
Pros:
- Lower lactose levels, meaning that those are have a low tolerances for milk products or are allergic, it is a much better fit
- Fast release into bloodstream, so for sprinters and bodybuilders, it is fantastic during explosive, lean muscle building workouts
- Much lower caloric content; contains less fat and carbohydrates than concentrate
Cons:
- As a health supplement, contains less antioxidants and amino acids than concentrate
- More expensive
- Due to quick release nature, lose benefit of natural appetite suppression that whey protein concentrate offers.
Isolate vs Concentrate – Summary:
Overall concentrate is a better daily supplement for those looking to maximize the numerous benefits whey protein powder offers. Anyone looking for a daily shake and/or something to supplement endurance activities, whey protein concentrate is your best bet.
Isolate is a better product to choose if you are allergic to lactose, and your workouts are more geared towards fast twitch explosive power over slow twitch endurance.
Both are great supplements, so experiment with both and see which fits your lifestyle and activities better. Ideally if doing both weight training and looking to maximize the health benefits, many companies offer blends of isolate and concentrate to maximize the effects of both types of whey protein powder.
