Benefits of BCAAs for Women

Written by Kristen Carli, MS, RD

In the quest for achieving their best health, many women are turning to supplements to support their workouts and optimize their health. Among these supplements, BCAAs, or Branched-Chain Amino Acids, are incredibly popular. 

But what exactly are BCAAs, and do they hold benefits specifically tailored to women’s fitness needs? 

Let’s uncover the answers to these questions, and explore the advantages, recommended dosages, potential side effects, and the optimal timing for BCAA supplementation.

What are BCAAs?

There are 20 essential amino acids that the body needs to build and repair muscle. Amino acids also function as neurotransmitters and hormones. Of these 20 amino acids, 9 of them are considered essential because the body cannot make them on their own and they must be consumed through the diet or supplementation. 

BCAAs are a group of essential amino acids that consist of leucine, isoleucine, and valine. BCAAs are unique because they make up a substantial portion of the amino acids in our muscles, playing a crucial role in muscle growth and repair.

Why do Athletes Take BCAAs?

Athletes often supplement with BCAAs to support muscle growth and enhance performance and recovery. These amino acids offer several key benefits:

Muscle Recovery

BCAAs can help reduce post-workout muscle soreness and promote faster recovery. This is particularly beneficial for women who are into intense training or weightlifting.

Muscle Growth

Leucine, one of the BCAAs, is known for its role in stimulating muscle protein synthesis, which can lead to increased muscle mass and strength.

Reduce Fatigue

BCAAs can help support muscular endurance during workouts by reducing the production of serotonin, a neurotransmitter associated with fatigue.

Muscle Preservation

For women who aim to lose weight or cut calories, BCAAs can help preserve lean muscle mass, preventing the breakdown of muscle tissue for energy.

Are BCAAs Beneficial for Women?

Absolutely! While BCAAs have long been used by male bodybuilders, women can also benefit from BCAA supplementation

Whether you’re an avid runner, a dedicated yogi, or a weightlifting enthusiast, BCAAs can support your fitness goals. They offer the same muscle recovery, growth, and fatigue-reducing advantages to women as they do to men.

BCAAs can be particularly beneficial for women who actively resistance train or participate in high-intensity workouts. Additionally, they can be a valuable tool for women pursuing fat loss goals, as they help preserve precious muscle mass during calorie deficits.

How Much BCAAs Should Women Take?

The optimal dosage of BCAAs can vary depending on your goals and workout intensity. As a general guideline, women can start with a daily dosage of 5 to 10 grams of BCAAs. However, it’s important to read the label of your BCAA supplement, as dosages can vary between brands.

Are there Risks of Side Effects With BCAAs?

BCAAs are generally considered safe when taken within recommended doses. However, like any supplement, there are potential risks associated with excessive consumption. These may include digestive issues such as nausea, diarrhea, or stomach cramps.

If you have any medical conditions or are taking medications, ask your healthcare provider before introducing BCAAs or any other supplement into your routine. 

When is the Best Time to Take a BCAA Supplement?

The best time to take your BCAA supplement is before or after a workout. Some research shows that taking BCAAs before exercise decreases muscle soreness and markers of muscle breakdown. Other studies suggest that there is little difference between taking BCAAs before or after a workout. Both resulted in similar increases in strength and body composition.

Ultimately, the best time to take BCAAs depends on your personal preferences and workout routine. Some women find it beneficial to take BCAAs both before and after their workouts to maximize their advantages.

What to Look for in a BCAA Supplement?

When selecting a BCAA supplement, quality matters. Some key factors to consider include ingredients, purity, flavor, and amino acid ratio. 

Opt for a BCAA supplement with minimal additives and artificial ingredients. Ensure the product is free from contaminants by selecting a reputable brand with third-party testing. Look for a supplement with a balanced ratio of leucine, isoleucine, and valine. A common ratio is 2:1:1.

Lastly, choose a flavor that appeals to you, as you’ll be more likely to stick to your supplement regimen.


BCAAs aren’t just for male bodybuilders; they can also be extremely beneficial for women who want to support their fitness goals. Whether you’re aiming to build muscle, lose fat, recover faster, or reduce workout fatigue, BCAAs can play a vital role in helping you achieve your fitness goals.
