For muscle building, several supplements have shown varying levels of effectiveness based on scientific research:

1. Creatine: Widely recognized for its role in enhancing muscle mass and strength, especially when coupled with resistance training. Creatine works by increasing ATP production, which fuels muscle contractions¹²³.

2. Protein Supplements: Including whey, casein, and plant-based proteins. These help meet the increased protein demands necessary for muscle repair and growth. Consuming protein around workout times (pre- or post-exercise) can be particularly beneficial⁴⁵.

3. Branched-Chain Amino Acids (BCAAs): These include leucine, isoleucine, and valine. BCAAs help to reduce muscle soreness, enhance muscle protein synthesis, and prevent muscle breakdown⁶⁷.

4. Beta-Alanine: Helps to buffer acid in muscles during high-intensity exercise, which can improve performance and delay fatigue⁸⁹.

5. HMB (Beta-Hydroxy Beta-Methylbutyrate): This compound may help reduce muscle protein breakdown, leading to increased muscle mass over time¹⁰¹¹.

6. Caffeine: Known for its ergogenic effects, it can enhance exercise performance by increasing focus, reducing the perception of effort, and improving endurance¹²¹³.

7. Citrulline Malate: May improve blood flow, reduce muscle soreness, and enhance ATP production, which can boost exercise performance¹⁴¹⁵.

8. Nitrate: Usually derived from beetroot juice, it can improve muscle efficiency and endurance through enhanced nitric oxide production¹⁶¹⁷.
