The Benefits of BCAAs: What Are They?
BCAAs are one of the most popular amino acids found in foods. These three amino acids have been used for centuries as dietary supplements because they provide many health benefits. The main reason why these three amino acids are so effective is due to their structure which consists of two branched chains (L-isoleucine and L-leucine) and a single chain (Isoleucine).
These three amino acids are considered essential fatty acid (EFA), meaning that humans cannot synthesize them. However, it is possible to obtain them through diet or supplementing with these EFA’s.
BCAAs are very beneficial when consumed in large amounts because they help increase muscle protein synthesis and reduce catabolism, both of which aid in weight loss efforts. Furthermore, there is evidence that suggests that bcaa supplementation may improve athletic performance.
In fact, research shows that bcaa supplementation may even enhance recovery after exercise. So if you’re looking to lose fat and build muscle, then taking a BCAA supplement might just be right for you!
How Does BCAAs Work?
There are several mechanisms by which bcaa works. One mechanism involves the release of growth hormone (GH) into the bloodstream. GH stimulates protein synthesis in various tissues including muscles.
The second mechanism involves improved liver function. BCAAs play an important role in liver function because it can prevent liver damage.
Research shows that leucine is the main amino acid responsible for these effects. However, bcaas are most effective when taken in a 2:1:1 or 4:1:1 ratio. In other words, leucine is the main active ingredient, but is most effective when taken alongside isoleucine and valine.
The third mechanism involves the increased activity of a neurotransmitter called GABA. GABA has been shown to relax the body and mind, which can lead to drowsiness. However, it is also shown to improve alertness and reduce stress.
Research shows that bcaa supplementation may reduce anxiety and depression in people with bipolar disorder. GABA also causes the brain to release more dopamine, a neurotransmitter that activates the reward center in your brain.
This is the main reason why people who take BCAA supplements report feeling happier and calmer. All of these mechanisms work together to help improve your mood, increase your happiness, and reduce muscle soreness after a workout.
Researchers are currently studying other potential uses for BCAAs such as improving memory and cognition in elderly patients with Alzheimer’s disease. More research is needed to confirm these findings.
How Do I Take BCAAs?
The most effective way to take a BCAA supplement is to take 5 grams of a 2:1:1 ratio 30-60 minutes before working out. It’s best to take this dose with food because the amino acids can reduce your appetite.
This dose should be increased if you’re doing intensive exercises that last longer than an hour. The maximum amount that you should take in a day is 8 grams. Taking higher than this can increase the chances of developing diarrhea and other side effects.
Other supplements like glutamine should not be taken at the same time as BCAAs because they both compete for entry into the cells. However, there are certain circumstances in which taking both can be very beneficial.
For example, if you are suffering from a serious injury or illness, you should consider taking both glutamine and BCAAs. This is because both increase the rate of muscle protein synthesis and improve recovery after an illness or trauma.
The Benefits of BCAAs
There are several benefits to taking a BCAAs supplement. The most noticeable benefit is that taking BCAAs can increase your strength, endurance, and speed during an intensive workout program. They can be taken before, during, and after a workout.
They can also improve your mood and alleviate mental stress and depression by increasing the release of certain neurotransmitters (chemical messengers) in the brain.
Studies show that leucine, one of the three BCAAs, can increase muscle mass and help you lose weight if you are overweight.
It can also help improve cognition and memory in older people, as well as prevent cognitive impairment and Alzheimers disease.
One of the most common reasons why people take BCAAs is to prevent muscle breakdown and soreness during and after a workout. This is especially true for bodybuilders and athletes who are constantly pushing themselves to the limit.
The Downsides of BCAAs
There are very few side effects to taking BCAAs. Some people have complained of stomach pain and diarrhea. However, this only seems to happen when large amounts (20 grams or more) are taken at a time. It is best to spread out the doses throughout the day rather than taking all the supplements at once.
If you are older than fifty, dont suffer from an eating disorder, or have a medical condition, its not reccomended that you take BCAAs because your body already has a sufficient amount of the amino acids.
If you have an eating disorder (anorexia or bulemia) do not take BCAAs. Studies have shown that athletes with these disorders can develop imbalances in their amino acid levels.
A Word of Caution About BCAAs
There are some products being sold as BCAAs that are nothing more than artificial sweeteners and coloring. Make sure you read the ingredients before purchasing anything.
