The biggest reason some studies show supplements work and some don't are as follows: a lot of supplements straight up don't do anything. Sometimes the ones that do are applied in the wrong situations or perhaps before a person's body is healthy enough biochemically to actually use the nutrients. The last one is that because many supplements don't contain what they claim on the label, many studies conducted are simply testing pixie dust and not the actual nutrients themselves.

Both your health AND performance/fitness will take off.
What to do about this? In a nutshell, know what you are taking. Be sure anything you supplement with is third-party tested, lab validated and inspected for quality of sourcing by independent authorities. Inspect what you expect. You wouldn’t eat at a restaurant that wasn’t cleared by the health inspectors. Same concept.
Understanding is power.
