Branched Chain Amino Acids (BCAAs) consist of the three essential amino acids:
- L-Leucine
- L-Isoleucine
- L-Valine
As dietary supplements, BCAAs are incredibly popular among athletes, bodybuilders, and fitness enthusiasts. For over 35 years, they’ve been recognized for their ability to stimulate muscle protein synthesis1Wolfe RR. Branched-chain amino acids and muscle protein synthesis in humans: myth or reality?. J Int Soc Sports Nutr. 2017;14:30. Published 2017 Aug 22. doi:10.1186/s12970-017-0184-9. While traditionally marketed toward men, research demonstrates that BCAAs also offer significant benefits for women. This article will explore the advantages of BCAAs for women.
Understanding BCAAs
BCAAs are essential amino acids, meaning the human body or other mammals cannot synthesize them, and must be obtained through food or supplements. As fundamental building blocks of life, BCAAs play a critical role in various biological processes. They act as signaling molecules, activating key functions such as protein synthesis and insulin secretion.2Neinast M, Murashige D, Arany Z. Branched Chain Amino Acids. Annu Rev Physiol. 2019;81:139-164. doi:10.1146/annurev-physiol-020518-114455
Research suggests that BCAAs also aid in recovery from high-intensity exercise and promote cognition, focus, and psychomotor function3Raizel R, Coqueiro AY, Bonvini A, Tirapegui J. 1 - Sports and Energy Drinks: Aspects to Consider. In Sports and Energy Drinks. Volume 10: The Science of Beverages. Woodhead Publishing; 2019:1-37.. Studies have shown that BCAA supplementation can significantly reduce skeletal muscle breakdown in active and resting individuals, 4Louard RJ, Barrett EJ, Gelfand RA.

It’s important to understand that BCAAs are not a substitute for protein. Instead, they consist of three key amino acids that are part of the full amino acid profile found in complete proteins. Likewise, BCAAs don’t serve the same functions as creatine, though they can be used as part of a comprehensive program for muscle repair and growth that includes both protein and creatine.
The “Big Three”: Leucine, Isoleucine, and Valine
Leucine, isoleucine, and valine offer various benefits for muscle health when taken collectively or individually. In animal research16Lim CH, Gil JH, Quan H, Viet DH, Kim CK. Effect of 8-week leucine supplementation and resistance exercise training on muscle hypertrophy and satellite cell activation in rats. Physiol Rep. 2018;6(12):e13725. doi:10.14814/phy2.13725, leucine supplementation combined with regular exercise increased skeletal muscle activity and improved muscle quality. In human research17Ispoglou T, White H, Preston T, McElhone S, McKenna J, Hind K. Double-blind, placebo-controlled pilot trial of L-Leucine-enriched amino-acid mixtures on body composition and physical performance in men and women aged 65-75 years. Eur J Clin Nutr. 2016;70(2):182-188. doi:10.1038/ejcn.2015.91, when EAAs (inclusive of BCAAs) were supplemented along with 20% or 40% leucine, there was a significant improvement in lean muscle mass (i.e., muscle). Additional human research18Pathak K, Zhao Y, Calton EK, et al. The impact of leucine supplementation on body composition and glucose tolerance following energy restriction: an 8-week RCT in adults at risk of the metabolic syndrome. Eur J Clin Nutr. 2024;78(2):155-162. doi:10.1038/s41430-023-01360-1 demonstrated that leucine supplementation during caloric restriction led to better preservation of muscle mass.
Isoleucine plays vital roles in growth, immune function, protein and fatty acid metabolism, and glucose transportation. Recent studies suggest that isoleucine may trigger the expression of host defense peptides (such as β-defensins), which help regulate both innate and adaptive immunity19Gu C, Mao X, Chen D, Yu B, Yang Q. Isoleucine Plays an Important Role for Maintaining Immune Function. Curr Protein Pept Sci. 2019;20(7):644-651. doi:10.2174/1389203720666190305163135. Isoleucine also contributes to hemoglobin production, the oxygen-carrying pigment found in red blood cells20Isoleucine. Healthy Encyclopedia. University of Rochester Medical Center. Retrieved August 8, 2024 from https://www.urmc.rochester.edu/encyclopedia/content.aspx?contenttypeid=19&contentid=Isoleucine..
Valine has been shown to increase the expression of genes involved in mitochondrial biogenesis (i.e., making new mitochondria) and dynamics21Sharma S, Zhang X, Azhar G, et al. Valine improves mitochondrial function and protects against oxidative stress. Biosci Biotechnol Biochem. 2024;88(2):168-176. doi:10.1093/bbb/zbad169, which is important since mitochondria are the parts of our cells that make energy (ATP). The more mitochondria you have, the more energy you can make. The same research showed valine reduced oxidative stress in the mitochondria and improved ATP production.
Should Women Take BCAAs?
Absolutely! According to Lionel University, the recommended daily intake of BCAAs for healthy women is at least 9 grams per day. However, it’s safe to supplement with up to 20 grams of BCAAs daily for six weeks.22BCAAs for Women: What You Need to Know. Lionel University. Retrieved October 14, 2024 from https://blog.lionel.edu/bcaas-for-women.
Lionel University has also highlighted several benefits of BCAA use for women:
- First, BCAAs can help protect against muscle loss. Research shows that women begin to lose muscle tissue, or lean body mass, after age 40. Maintaining a low body fat percentage and a high lean body mass offers significant health benefits. Therefore, even if building muscle isn’t a primary goal, women may still benefit from BCAA supplementation. The muscle growth supported by BCAAs can help prevent age-related muscle loss.
- Second, women generally have a slower metabolism than men, partly due to differences in muscle mass and body size. A slower metabolism can make it harder to maintain a healthy weight. However, BCAAs, commonly found in high-protein diets, can help the body more efficiently metabolize fat and glucose, promoting lean muscle mass. This makes BCAA supplements a valuable consideration for women.
- Third, BCAAs support hormonal balance by regulating hormones such as leptin, adiponectin, and glucagon. These hormones play crucial roles in moderating appetite, converting fat cells into energy, and maintaining stable blood sugar levels. Additionally, BCAAs promote the release of hormones essential for a healthy immune response and mental well-being.
Health Benefits of BCAAs for Women
What are BCAA benefits for women? While BCAAs provide the same sports nutrition advantages for women and men, research also points to additional, specific benefits for women.
For instance, a placebo-controlled randomized clinical trial23Novin ZS, Ghavamzadeh S, Mehdizadeh A. The Weight Loss Effects of Branched Chain Amino Acids and Vitamin B6: A Randomized Controlled Trial on Obese and Overweight Women. Int J Vitam Nutr Res. 2018;88(1-2):80-89. doi:10.1024/0300-9831/a000511 involving overweight and obese women on a moderately reduced-calorie diet (-500 calories/day) found that those women who supplemented with BCAAs and vitamin B6 experienced improvements in waist-to-hip ratio and promoted leaner leg mass compared to the placebo group.
In another randomized controlled study24Ikeda T, Matsunaga Y, Kanbara M, et al. Effect of exercise therapy combined with branched-chain amino acid supplementation on muscle strength in elderly women after total hip arthroplasty: a randomized controlled trial. Asia Pac J Clin Nutr. 2019;28(4):720-726. doi:10.6133/apjcn.201912_28(4).0007, elderly women who had undergone hip replacement surgery supplemented with BCAAs, as they often experience a prolonged decline in muscle strength post-surgery. The study found that BCAAs, combined with muscle-strengthening exercises, significantly improved knee and upper arm strength.
Another randomized controlled trial25Mittleman KD, Ricci MR, Bailey SP. Branched-chain amino acids prolong exercise during heat stress in men and women. Med Sci Sports Exerc. 1998;30(1):83-91. doi:10.1097/00005768-199801000-00012 found that BCAA supplementation helped prolong exercise duration under heat stress in both women and men.
Additionally, another study26Chang CK, Chang Chien KM, Chang JH, Huang MH, Liang YC, Liu TH. Branched-chain amino acids and arginine improve performance in two consecutive days of simulated handball games in male and female athletes: a randomized trial. PLoS One. 2015;10(3):e0121866. Published 2015 Mar 24. doi:10.1371/journal.pone.0121866 showed that supplementing with BCAAs and arginine improved performance in intermittent sprints during simulated handball games for well-trained female (and male) athletes, potentially by alleviating central fatigue.

Is BCAA powder for women the best choice? It is certainly a good choice. There are a variety of different delivery forms in which BCAA supplements can be offered. In addition to powders, these include tablets and capsules. Furthermore, BCAAs can be utilized in functional food products as well.
In research, BCAA supplementation was used in various strategies, including pre-load only, at the exercise day only, at pre-load and exercise day, on the exercise day and recovery period, and at pre-load, exercise day, and recovery period. In any case, seven of the studies included supplementation with BCAA at a ratio of 2:1:1 (leucine: isoleucine: valine), although the BCAA ratio was 3:1:2 in two studies.30Khemtong C, Kuo CH, Chen CY, Jaime SJ, Condello G. Does Branched-Chain Amino Acids (BCAAs) Supplementation Attenuate Muscle Damage Markers and Soreness after Resistance Exercise in Trained Males? A Meta-Analysis of Randomized Controlled Trials. Nutrients. 2021;13(6):1880. Published 2021 May 31. doi:10.3390/nu13061880 Whichever ratio you choose, the data indicates that leucine should be the predominant amino acid.
