What are Branched Chain Amino Acids (BCAAs)?
Before whey protein shakes, creatine, and AAKG ranked supreme as popular bodybuilding supplements, the branched-chain amino acids were the hot ticket for all athletes and bodybuilders. Today, BCAAs are back on the must-have list of supplements. That’s because they work extremely well to enhance muscle growth, strength, energy and even fat loss. If you're not using them, here's a few words about why you should.
How essential are these three aminos?
The three Branched Chain Amino Acids (BCAAs), so named because of their branched chemical structure, are essential because your body can’t make them from food or other compounds. Although there are about 20 amino acids that your muscles use for muscle growth, these three BCAAs make up one-third of the total amino acids in your body's muscles.
How do they work?
What's really special about these three aminos is how your body handles them. When you ingest amino acids as individual aminos or as protein, they travel to your liver, which immediately breaks them down and uses them for fuel if the body needs them for energy rather than for rebuilding muscle and other tissues. Yet, the liver tends to spare BCAAs, sending them directly to the muscles to be used for building muscle or for fuel.
Your muscles can use BCAAs, unlike other aminos, directly for fuel. This gives BCAAs two unique properties.
First, during workouts, muscles readily use BCAAs for fuel.
Second, during rest, such as after your training, BCAAs are used for building muscle.
Pre training muscle fuel
Intense and longer workouts will rob BCAAs from your muscles because your body uses BCAAs as fuel. To counteract this, take a spoonful of BCAA powder right before you train. Because you have made additional BCAAs readily available to the muscle as a direct source of energy, your energy levels will be higher during the workout.
Besides boosting energy levels by providing a direct fuel source, BCAAs also enhance energy through another mechanism, one that involves the brain. French researchers discovered that during exercise, an amino acid metabolite known as 5-hydroxytryptamine (5-HT) signals the brain that the body is fatigued, causing it to reduce muscle strength and endurance. Several research studies have confirmed that taking BCAAs before workouts lowers the amount of tryptophan that gets into the brain, thus lessening 5-HT levels and fatigue. BCAA help prevent you feeling tired during workouts, which will allow you to train harder and longer, encouraging greater muscle growth.
BCAA supplementation can also help to enhance mood and brain function by reducing brain fatigue through this same mechanism.
Post training muscle growth
More energy to workout is important, but the critical BCAA benefit is the ability to drive muscle growth. BCAAs increase growth by directly stimulating muscle protein synthesis, building up your muscle protein (protein synthesis), one amino acid at a time, like building a brick wall.
BCAAs also enhance muscle growth by facilitating growth hormone. A 2001 study from Italian researchers found that athletes taking BCAAs for one month had higher levels of growth hormone and growth hormone binding protein after exercise. GHBP is important because it acts as a carrier for GH in the blood, taking it to the muscles where it triggers growth.
BCAAs also affect the catabolic hormone Cortisol. A 2006 study found that athletes consuming BCAAs had a significant reduction in Cortisol levels during and after exercise as compared to those taking a placebo. This blunting effect on Cortisol is critical because Cortisol is a catabolic hormone that interferes with the anabolic hormone, testosterone, and encourages muscle breakdown. In fact, numerous studies have confirmed that athletes taking BCAAs have significantly less muscle breakdown, delayed muscle soreness after exercise, and enhanced muscle recovery.

There are no additional sweeteners or fillers, just pharmaceutical grade Branched Chain Amino Acids. |
Directions : Serving size
Add one serve – that’s one heaped teaspoon (5g) to 200ml of your protein shake and mix for 15 to 20 seconds using a glass and spoon, or a shaker.
When to take BCAAs :
Knowing when to add BCAAs to your day can make all the difference to the benefits you experience. We recommend about 5-10 grams of BCAAs per serving and at least four doses per day. These four doses should be taken:
• First thing in the morning,
• Within 30 minutes of working out,
• Within 30 minutes after working out; and
• With your last meal of the day. |
