Protein Isolate vs Protein Concentrate

[dizzel]

I'm aware that Protein Isolate is a more pure compound and carries less fat and lactose per serving but, besides price, is there really a difference when it comes to fueling muscle growth? Anyone have a preference?

yes. isolate digest at a faster rate which is why it's recommended for post work out.

if your planning on having a few shakes a day and your not lactose intolerant i would go with a blend (iso + concentrate) it's more cost effective. Just look at the % of protein per serving. Blends range from 70-80ish% and isolates 90-93ish% so your only losing a few grams of protein per shake. But if your just having one shake per day and it's post training I would use an isolate, this is if your getting the rest of your protein through whole foods.

Would give an answer if was in the right section.

It's not just the percentage of protein that changes. The filtration process is different and using a cold filtered or microfiltration process for whey proteines helps to acheive a greater preservation of the natural BCAA's, glutamine and protein fractions.

Protein fractions are what will separate a higher quality (isolate) from an ordinary whey.

There are 4 major fractions and 4 minor fractions, these increase the BV of the protein, act as precursors to anti-oxidants, increase immune function, stimulate release of glucagon, stimulate release of insulin-like growth factors and so on.

I am guessing with better extraction techniques in the future we will be able to purcahse these fractions on their own, possibly in pill form. For now, use a good isolate imo.
