Five supplements that dr. Mike Israetel says are actually worth it

Sports scientist and bodybuilding expert dr. Mike Israetel shares his perspective on supplements that genuinely deliver results. According to him, most supplements are unnecessary, but a handful of exceptions deserve serious attention.

At the top of his list is protein powder, followed by creatine, the supplement with the strongest scientific backing for strength and recovery. He also highlights omega-3 fatty acids, vitamin D3 and fiber as valuable additions to a regular diet.

Israetel emphasizes that these products are not a replacement for a solid nutrition and training routine. They fill the gaps where a daily diet falls short, and that is precisely why he considers them relevant for serious athletes.

For CrossFit and Hyrox athletes, who combine high training volumes with significant recovery demands, creatine and protein powder in particular can be practically useful. Making a deliberate choice for proven supplements saves money and prevents disappointment.
