I get asked a lot about taking vitamin supplements etc while trying to hit your goals of gaining lean muscle and losing fat. I saw this on a post today and thought it useful to share.

BCAA stands for Branched Chain Amino Acids.

Amino acids are the building blocks of protein. They build up muscle and repair muscle after breakdown. So taking amino acid supplements helps you get those gains, and prevents your muscles from wasting away.

There are 22 amino acids in your body, but 3 major ones that are particularly good for repair. These 3 are the amino acids that make up BCAA supplements:


Leucine is helpful in muscle repair. Have you ever been sore after a workout? (I mean who hasn’t?). Well leucine is an amino acid that can help you repair your muscles and recover quicker. It helps prevent your muscles from being “eaten up” due to calorie deficits, hard workouts, or stress.

Isoleucine helps your body utilize carbs for energy. This helps fuel your workout and it allows your body to use up your carbs rather than store them. Your body will energy from your diet rather than from breaking down your muscles to fuel your workout.

Valine works to build muscle, repair tissue, and boost energy.

Enough science, what do BCAAs actually do for you?

BCAAs Stop Catabolism
What is catabolism? (Not cannibalism, don’t worry).

Catabolism is muscle breakdown.

When you are on a clean meal plan, your body breaks down fat cells to use for energy. That’s what we want, right? But, the bad news is your body also breaks down muscle to use for energy.

That’s the last thing you want when you’re trying to gain lean muscle mass.

If you are trying to lose some fat, but not muscle, BCAAs are very valuable.

A lot of research has been done to show that BCAAs increase the rate of protein synthesis (muscle growth), and decrease the rate of catabolism (muscle breakdown).

So that means you can eat clean, exercise, burn fat, and your muscles will stay nice and lean.

Would You Rather…
Would you rather your body use your carbs or store them as fat?

I think most of us can agree that we’d rather use carbs for energy!

That’s exactly what BCAAs help you with. BCAAs (Isoleucine specifically) increase your body’s ability to use carbs for fuel. This means your body will burn the carbs you eat more efficiently, rather than storing them on your hips!

If you’re already working out and eating healthy, BCAAs can push your fat loss to the next level. They are not a miracle pill, but they are proven to help enhance your body’s ability to use energy rather than store it as fat.
