But what is the difference between amino acids and BCAAs?

Amino Acids Vs BCAAs

The difference between BCAA and amino energy is that BCAAs are made up of only three essential amino acids, isoleucine, leucine and valine.

These three amino acids have a lot of benefits but mostly they increase endurance, recovery and muscle buildup.

Essential amino acids are made up of 8 essential amino acids: L Tryptopha, L Methionine, L Histidine, L Threonine, L Phenylalanine, L Lysine and the three BCAAs.

The other five are not critical for muscle building, but your body needs them from food since they cannot be produced inside you.

Benefits of BCAAs

The benefits of BCAAs are numerous, and we will explain the important ones.

Keep in mind that the benefits you get from BCAAs depend on the amount.

  • Stimulates Lean Mass Buildup

BCAAs provide a lot of benefits, but the most important is they lead to lean muscle mass development.

Men and women who regularly take BCAA supplements are the ones most likely to have lean muscle mass.

  • Less Belly Fat

A lot of the attention has been focused on what BCAAs can do to build up muscle. What you may not realize is that this is just as effective for getting rid of belly fat.

Not only does it eliminate belly fat, but it also functions as a deterrent for belly fat. It is also effective as a means of keeping body fat to a minimum.

  • Improves Protein Synthesis

Protein synthesis is your body’s way of building up muscles. When you lift weights and do strengthening exercises, your muscle tissues get torn down.

When you rest and recover, protein synthesis begins the repair process. The muscles torn during your weightlifting sessions are repaired and become bigger to accommodate the weights you’re lifting.

That is how protein synthesis works in principle. However its efficiency depends on how much amino acids you have.

By taking BCAA supplements you’ll speed up the process and you’ll end up with harder, bigger muscles.

BCAAs also prevent muscle cells from breaking down so you’ll keep the lean mass you worked hard to build.

  • Provides Other Health Benefits

While fat burning and protein synthesis are for muscle building, you get other health benefits such as insulin sensitivity and glucose uptake.

These supplements are ideal for some diabetics because it enhances metabolic markers.

  • Complements Workout and Diet

As any health nutritionist will tell you, BCAA supplements are no substitutes for working out.

You also need to go on a healthy diet to ensure you get the best possible results.

However, working out and going on a diet is not enough. Only if you take BCAA supplements will you build muscles.

BCAA supplements also play a vital role in energy and muscle production. As your body gets used to the BCAAs and amino acids, your body will reap the benefits and improve your physique.

BCAAs also increase your dietary intake and the amount of nutrients in your body. With the proper amount of nutrients, vitamins and minerals, you’ll avoid health problems and no longer have to take a ton of supplements.

BCAAs also do more than just build muscles however, as it also improves motivation and reduces fatigue.

Amino Acids BCAA

Why BCAAs are Essential for Muscle Building and Improving Health

We have already explained what BCAAs are and how their difference from other amino acids so we will not repeat that here. What we want to point out is that BCAAs make up 40% your body’s amino acid needs.

By making amino acids a part of your daily regimen, you’ll be able to meet your daily requirements more easily.

BCAA Sources: Food vs Supplements

Now the question becomes, which BCAAs are more reliable, those found in foods or supplements?

BCAAs are available in some foods including those that are rich in protein. The best choices are whey protein, eggs, salmon, beef and chicken.

Eating these means you’ll get BCAAs, but while it’s a good idea to include these in your diet, they should not be your only source of BCAAs.

The problem with food based BCAAs is it’s not always possible to eat these foods. You also cannot be certain of how the food was processed and if it still contains the BCAAs your body needs.

There is also no way to be certain if the food has the BCAAs you need to build up muscles.

The fact is it is more practical to get BCAAs from supplements. Whether it is in capsule or powder form, you’re assured of getting the amount of BCAAs you’re going to need for muscle and strength building.

If you’re an athlete who needs to eat specific types of food, you’re going to get more out of your exercises.

For Old and Young

One of the most common misconceptions with BCAA supplements is assuming that it is only for young people. That is not true at all since even older individuals will benefit from it as well.

BCAAs, in particular leucine, is very effective in boosting protein synthesis by up to 145%.

These benefits do not distinguish between young and old people. What matters is that you take BCAAs to augment your regimen. Another common practice is to just take leucine.

The belief is that leucine is all you need for protein synthesis boosting. That is not true as you also need the other BCAAs for maximum effect.

Supplement Side Effects

There should be no side effects when you take amino acids since your body needs them. In fact there is a good chance you will feel weaker if you don’t take them.

However, just like with all health supplements you should take these only as directed. Do not take more than what is recommended because it might cause problems later on.
