Muscle Supplements for a Six Pack

Developing six pack abs means decreasing your body fat percentage. Everyone has abdominal muscles underneath their skin, says "The Abs Diet" author David Zinczenko. In order to show them the light of day, you need to focus on diet. There are powerful natural supplements than can help you lose body fat faster to define your midsection and boost muscle building at the same time. Add these supplements to your diet to increase fat burning and see your six pack abs.

L-Glutamine

Considered a conditionally essential amino acid, glutamine can boost fat burning in several ways to help you reveal your hidden six pack. Glutamine play a direct role in fat burning and helps the body store carbohydrates as muscle glycogen. By boosting muscle recovery and sparing muscle tissue from catabolism, glutamine also promotes lean muscle retention, says "Good News on Glutamine" by Matthew Kadey. Take 5 to 10g, up to three times daily.

BCAAs

The branched-chain amino acids are L-leucine, L-valine and L-isoleucine; they get the name from their branched molecular structure, which makes them unique among amino acids. According to "Natural Anabolics" author Jerry Brainum, BCAAs fuel muscles directly, bypassing the liver when they absorb into the body. This prevents muscle breakdown, triggers protein synthesis and makes sure that your body uses fat for energy, rather than your own hard-earned muscle. Take 5g before, during and/or after workouts.

Whey and Casein Protein

The combination of whey and casein proteins represents one of the most powerful supplement strategies for gaining muscle and burning fat. Nature's preeminent growth food, milk, contains both whey and casein protein. Whey digests quickly, while casein has a much slower rate of digestion. "Xtreme Lean" author Jonathan Lawson attributes these combined traits to staying full longer, burning more fat and experiencing less muscle loss while dieting. Use a 50/50 whey casein blend between meals or after your workout.

Forskolin Extract

According to "Supplements 101" by Jim Stoppani, forskolin has many fat burning effects that can help you define your abs. By boosting a critical enzyme involved in testosterone production, forskolin helps the body produce more of the fat burning and muscle building hormone. In addition, forskolin may boost thyroid function, though more research is needed on this point. Regardless, forskolin decreased body fat levels in exercising men, says Brainum. Take 25 to 50 mg of forskolin extract three times daily.

L-Arginine

L-Arginine acts as a nitric oxide of NO precursor in the body. NO dilates blood vessels, decreasing blood pressure and allowing for more blood flow to working muscles. During your training sessions, this means better muscle pumps and more energy. More importantly, however, higher NO means that your body burns fat faster and more efficiently, says "Everything You Need to NO" by Jordana Brown. Take up to 3g, three times daily.
