Some people may consider BCAAs (branched-chain amino acids) to be a waste of money because they believe that they can get enough of these amino acids through their diet. BCAAs are found in protein-rich foods such as meat, fish, eggs, and dairy products, so it is possible to meet your BCAA needs through food alone.
Additionally, some studies have suggested that the benefits of BCAA supplements may be limited, particularly for people who are already consuming adequate amounts of protein. For example, a review of studies published in the Journal of the International Society of Sports Nutrition found that while BCAA supplements may improve muscle protein synthesis and reduce muscle soreness, the benefits are generally small and may not be noticeable in people who are already consuming sufficient protein.
That being said, there are some situations in which BCAA supplements may be beneficial, such as for athletes and bodybuilders who are training intensely and may need higher levels of BCAAs to support their goals. BCAAs may also be helpful for people who are following a low-calorie diet or who are fasting, as they may help preserve muscle mass during periods of restricted calorie intake.
Ultimately, whether or not BCAAs are a waste of money depends on individual circumstances and goals. If you are considering taking BCAAs, it's important to talk to a healthcare professional to determine whether they are appropriate for you and your needs.
