To increase muscle mass, several nutritional supplements have demonstrated efficacy when combined with resistance training (RT):

1. Whey Protein: Whey protein is widely recognized for its benefits in promoting muscle protein synthesis. Studies have shown that whey protein can significantly increase lean body mass when taken in conjunction with RT¹².

2. Creatine: Creatine supplementation is effective for increasing muscle mass and strength, particularly in young, healthy individuals engaged in regular resistance training³.

3. Branched-Chain Amino Acids (BCAAs): While evidence is mixed, BCAAs, which include leucine, isoleucine, and valine, can stimulate muscle protein synthesis and reduce muscle protein breakdown⁴.

4. Polyunsaturated Fatty Acids (PUFAs): These fatty acids have shown to consistently increase or preserve muscle mass and strength over the long term⁵.

5. Beta-Alanine: This amino acid helps buffer acid in muscles, which can delay fatigue and improve exercise performance, indirectly promoting muscle growth⁶.

6. Vitamin D: Supplementing with vitamin D can help improve muscle function and strength, which can support overall muscle mass gains⁷.

7. HMB (Beta-Hydroxy Beta-Methylbutyrate): HMB has been shown to help decrease muscle protein breakdown, thus supporting muscle mass gains⁶.

In summary, combining these supplements with a structured resistance training program can help optimize muscle mass gains.

Would you like me to find specific products for any of these supplements?
