What is BCAA?

The abbreviation BCAA stands for Branched-Chain Amino Acids.

BCAA includes three types of organic compounds - leucine, isoleucine, and valine. Their “task” is to build protein in the body, that is, they contribute to the growth of muscle mass.

Broken down BCAAs bypass the liver and go immediately to the muscles. This is the main feature of the essential amino acids trio. If you take each "aminka" separately, you can be surprised by their work. 

  • Isoleucine - normalizes sugar, increases endurance, and restores muscle tissue
  • Valine - adds muscle growth rate, stops protein breakdown, and accelerates muscle recovery and healing.
  • Leucine - controls blood sugar, enhances growth hormone, and restores skin, bones, and muscles. 

As you can see, together, these amino acids help burn fat, restore muscles, and prevent muscle aging!

Many studies have proven that the use of BCAAs gives the following effects: 

  • prevents the destruction of muscle structures (catabolism); 
  • lowers body fat; 
  • promotes the growth of lean muscle mass; 
  • stimulates the production of insulin
  • accelerates fat burning; 
  • enhances muscular strength
  • increases the effectiveness of other types of sports nutrition by 30-40%. 

We can assume that taking BCAAs will be useful both in fat burning and in gaining muscle mass.

Best BCAA for women

Are you wondering whether it is ok to use the BCAA for women? Our answer is yes, you’ll have no problem with it. Both men and women can take the supplements and pump up their bodies. 

For females with a body weight of 50-65 kg, the initial-intermediate level of fitness (we use this indicator as a correlation with training volume and intensity), 5-7 grams of BCAA a day is a norm.

For bodybuilders

As long as BCAAs are the best amino acids for muscle growth, bodybuilders has a special interest in taking BCAA supplements.

Sometimes sport athlets take BCAAs as a meal replacement - they dull hunger and preserve muscle. It is convenient to use BCAAs immediately after a workout, especially for those who like to take protein with milk, and milk quickly turns sour in a sports bag.

For weight loss

The 2009 research proved the efficiency of having BCAAs in the diet compared to other supplements. Strength-trained men who took 14 grams of BCAAs per day shed 1% more body fat and gained 4.4 pounds more muscle mass than the men who were eating whey protein.

If you want to get rid of extra pounds, BCAA supplements will be a great help for this. Take a BCAA drink (or mixed BCAA powder/pills) 3 times a day: in the morning, before training, and after it. 

If there are no workouts scheduled on this day, you can take the supplement in a reduced volume (2 times less) and only in the morning.

For the first time, take 5-8 g of the supplement - it will be a kickstarter.

Are BCAAs safe?

This is perhaps the eternal question that worries beginner athletes who have little experience in taking sports nutrition. 

Once again, it is worth emphasizing that BCAAs are amino acids obtained by special processing of proteins of natural origin. Therefore, these nutritional supplements are not at all dangerous but are necessary for athletes.

These substances have an amino build function and cannot harm your body.

Of course, there are contraindications for BCAAs: individual intolerance to the supplement's components. But in general, BCAAs are completely safe.

How to take BCAAs

You need to know how to take supplements to get the maximum profit from aminoacidos BCAA. The scheme depends on daily loads.

Drink the first portion of BCAA before going to the gym. How much depends on the form of release.

Don’t forget to give BCAAs time for absorption

  • For dissolved powder and liquid - 5-10 minutes is enough.
  • For capsules - you’ll need up to half an hour.

The second dose is immediately after the end of the workout. If it lasts more than an hour, you can take a few grams between sets.

If we talk about the daily dose of BCAAs, it will be up to 50 g per day. However, keep in mind that these measurements are not absolute and may vary.

The minimum dose of BCAA you should take is about 1 g of BCAA per 10 kg of body weight, which means that a person weighing 70 kg should take 7 g of branched-chain amino acids.


Are BCAAs safe to take every day?

BCAAs are amino acids found in animal proteins. They are harmless to the human body. This means that it is safe to take them every day.

Who needs aminoacidos BCAA?

BCAAs are vital for athletes and people who play sports long and hard. They may also be essential for those who follow a strict diet that does not include natural sources of BCAAs. The destruction of muscle tissue also may be the reason.

How to take BCAA powder?

Mix a serving of BCAAs with water as directed on the product label. Powder mixtures sometimes have a bitter taste and do not dissolve well. Another way is to take the required dose from a spoon and drink plenty of water.

Remember that the supplement is also available in capsules/pills, BCAA powder, and liquid/drinks. Capsules are the most effective form for absorption. But choose the best option for you!

Summing up

  • BCAAs are the best amino acids for muscle growth. It’s a complex of three amino acids necessary for the body, which come with food.
  • The supplement increases productivity during the day and endurance during training.
  • BCAAs prevent muscle breakdown and promote muscle growth.
  • The amino acid complex can be diluted in water, swallowed and washed down, or mixed with an isotonic drink. 

So, choose the form and dosage that suits you and pump your body! And don't be scared of the word “supplement." BCAAs are entirely safe.
