“…It is clear in the current literature that evidence is divided regarding the use of BCAA supplementation in individuals with cancer. Some research supports the benefits of BCAA supplementation, including improved recovery after chemotherapy marked by weight gain and increased energy levels (Deutz et al, 2011; Hachiya et al, 2020; Hassan et al, 2015; Katagiri et al, 2020; Kikuchi et al, 2016; Morihara et al, 2012; Nojiri et al, 2017; Storck et al, 2020; Tada et al, 2015; Yoshiji et al, 2013). On the other hand, other recent studies have reported that BCAA supplementation can be extremely harmful to individuals with cancer because cells can feed off BCAAs and stay alive even in anaerobic environments (Ananieva and Wilkinson, 2018; Ericksen et al, 2019; Lei et al, 2020; Lieu et al, 2020; Peng et al, 2020; Taherizadeh et al, 2021; Wang et al, 2018).…”
