Lets say a person, take me for example, eats every 2 hours. In this meal I eat about 50 grams of complete protein from an animal source (poultry or beef ect…). As I go to work out, my body is still digesting and breaking down the peptide bonds of the protein in my last meal. Theres sufficient amounts of all the aminos present. Digestion of a meal takes some time and often we’re still digesting our last one when we go on to our next.
With this steady supply of protein in the G.I, I’m not sure if adding any more would help. Especially considering it would have to “cut the line” and get absorbed way ahead of all the other food thats working its way through my gut.
I guess what I’m trying to word out is… I’m not sure if supplementing your diet with BCAA’s or Leucine is worth it if you are eating quality proteins in high amounts, frequently. On a cut, I may have different views.[/quote]
An interesting point!
But there are two things we should remember:
the body’s demand for protein and carbs increases exponentially during/after a workout and there’s lots of evidence to suggest that a protein/carb drink is very beneficial under those circumstances.
Leucine might possess a nutrient-partitioning effect in that it preferentially shuttles nutrients into muscle tissue rather than fat tissue.
And finally, I think there’s an instant gratification factor involved. For me, a great example was Myoblast. I personally saw a gradual but pronounced effect from taking Myoblast, but most people said “it didn’t do anything”, because when they read the article about it and started taking it, they expected to turn into Arnold in the next 2-3 months. When nothing like that happened (and they didn’t “feel” the supplement working), the common “diagnosis” was that the supplement was useless - it didn’t produce an effect quickly enough. Had you been taking it continuously for a year, however… But who has the patience for that, right? The l-leucine is a very similar story. If you take it with food, you won’t gain 5 lbs a month. But it might help you gain 5 lbs of extra muscle mass a year. Big deal, right? You wouldn’t even notice gaining those 5 pounds, not in 12 months. But that might mean 20-25 pounds of extra muscle in 5 years and that’s certainly something to write home about.
