What does it stand for?
BCAAs stand for Branched Chain Amino Acids. See, that was simple! Now let’s take it up a notch …
What are BCAAs?
There are, in fact, three Branched Chain Amino Acids. These are Leucine, Isoleucine, and Valine. They are 3 incredibly important amino acids that are found in several meats and eggs. What makes them important and “essential” is that your body is unable to make them on its own. As such, you do get them naturally if you consume a well-balanced diet.
However, to access their true benefits, most serious weightlifters take them in supplement form as well. Being aware of them and conscientiously adding them into your diet can allow you to get ahead in your fitness. To help break things down into more simple terms, we should look at what each one of the 3 BCAAs does exactly.
1. Leucine
The primary benefit of leucine is its ability to help reduce muscle soreness and improve recovery times. This is perfect if you are working out each day back-to-back and want to be able to perform at your best. But how does it do this?
Well, it can simultaneously work to prevent muscle protein breakdown and encourage MPS (muscle protein synthesis). This is the process of building new protein within your muscles. And, of course, this is essential to growth.
It also can help stabilise your blood glucose levels and improve your body’s hormone control. As such, Leucine seems to have garnered greater levels of research over the years and is widely considered to be the most important of the 3 BCAAs.
2. Isoleucine
When you consume carbohydrates of any kind, they either do one of two things. They could be transferred into your glycogen stores and then used as energy when you need it. Alternatively, they could be stored as fat.
Well, isoleucine is incredibly beneficial as it improves your body’s ability to use the glucose it has stored up. Most significantly, when you are working out. As such, you benefit from getting more energy during your workouts and hopefully less fat buildup over time.
What you should start to find, when regularly adding isoleucine into your diet, is that your blood sugar levels become more stable than before. Which can then help to prevent noticeably large spikes in your insulin levels.
3. Valine
The third and final essential branched-chain amino acid is valine. The effects valine has on your body are sort of a combination of those of leucine and isoleucine. It can help with:
- Repairing tissue damage
- Regulating blood sugar levels
- Promoting regular growth of muscles
- Giving your body greater levels of energy
- Aiding healthy brain functioning
To gain access to all of the aforementioned qualities, you should consume all 3 BCAAs at the same time. And indeed, it is far easier to get supplements that include all, as opposed to just one.
4 science-backed benefits that BCAAs can offer you
OK, so now that we’ve looked at the sorts of things that each one of the BCAAs can do for you on your own, let’s dig a little deeper into the 4 main health benefits BCAAs offer you. And rather than just taking our word for it, there are links through to the studies that support each claim as well!
1. Improving weight loss efforts
Studies that have taken place have indicated that those who consume 15 grams of BCAAs each day have a 30% lower risk of becoming overweight compared to those consuming 12 grams per day (1). By helping to better regulate how carbohydrates and glucose are used, it is expected that this can help prevent the buildup of fat.
Instead, that glucose gets used for energy, allowing you to work out at higher levels every time. By also helping to reduce recovery times, you can do more exercise in a shorter period. As such, BCAAs play a part in helping you to increase exercise levels and to shed more excess weight.
2. Reducing Delayed Onset Muscle Soreness (DOMS)
DOMS is the feeling you get the day or two after you have a heavy workout. For some, this feeling is great as it’s a sign that the workout went well. However, it can be incredibly annoying if you then want to work out again, but the muscle groups are too sore to do so. Well, BCAAs can protect against the muscle damage that occurs in workouts (2).
One study found that those who received BCAA supplements as opposed to a placebo could perform up to 20% better with the same exercises 24-48 hours after a session (3). It is believed that they can achieve this partly due to their ability to reduce blood levels in the enzymes lactate dehydrogenase and creatine kinase.
3. Reducing tiredness during workouts
BCAAs have been shown to reduce not only physical fatigue during workouts but also mental fatigue. This isn’t to say that your physical performance is necessarily enhanced, but the experiments have shown that individuals are less tired if they consume BCAAs either before or during a workout.
One study found that those who received BCAAs during a trial workout experienced 15% less fatigue than those who were given a placebo (4). Another found that those who received BCAAs during a cycle experiment could keep going for 12% longer than those who received the placebo (5).
4. Increasing your body’s muscle mass
Arguably, the main reason that weightlifters are drawn to BCAAs is their ability to increase muscle mass. This is a big claim and one that has been closely scrutinised for years. However, there is scientific proof to back this statement up. You can access this benefit as it is believed the BCAAs activate enzymes in your body that build muscle mass (6).
This is especially true if the supplement you consume has a higher proportion of leucine as opposed to isoleucine or valine (7). It is important to note, however, that the supplementary form of BCAAs is not necessarily the only way to access this benefit. This study found that taking whole protein supplements (which contain BCAAs naturally) is more effective for muscle growth than taking BCAAs individually (8).
How much BCAAs do you need in your diet?
As with the nutritional intake of anything, there is no hard and fast rule as to how much you should consume each day. However, due to the growing popularity of BCAAs, several studies have taken place into what the ideal amount to consume each day is. These findings range anywhere from 15mg to 65 mg per pound of body weight per day (9, 10).
However, a consensus should find that women need around 9 grams per day, whilst men need around 12 grams. If you do not exercise and eat a healthy, protein-rich diet, then you should not necessarily have any need to take supplements. However, if you work out, then you will benefit much more from taking BCAA supplements.
If this is the case, then you should aim for a supplementary intake of around 10 to 20 grams of BCAAs a day. Again, there is no hard and fast rule to this. And if you carry out a lot of high-intensity training each week, then you could benefit from taking more. That’s why it’s worth trialing different amounts to find a balance that suits your lifestyle best.
How many BCAAs do certain foods contain?
As mentioned throughout, BCAAs are not only found in supplements. They come naturally in eggs and many types of meat. So, if you’re curious as to how much you are already consuming, here’s a breakdown of the typical amounts found in different foods.
- 10g of chicken breast: 0.38g BCAAs
- 10g lean beef: 0.36g BCAAs
- 10g tinned tuna: 0.32g BCAAs
- 10g salmon: 0.35g BCAAs
- 10g beef steak: 0.36g BCAAs
- 1 egg: 1.3g BCAAs
- 10g peanuts (roasted): 0.4g BCAAs
For each of those, perhaps 45% is Leucine, whilst the remaining 55% is made up evenly of Valine and Isoleucine. This isn’t exact, but it is the general proportion. As you can see, if you are looking to consume a high level of BCAAs every day to keep up with your active lifestyle, it can be hard and expensive. As such, most serious weightlifters turn to other, much more convenient ways of buying BCAAs.
