We all experiment personally. I make a point of not looking for, or attributing any causality, to any immediate change. Then see how I fair over time. Obviously not a high standard, but reduces bouncing around between different regimens chasing coincidences and placebo effects. After several extended periods of taking multi-minerals and not taking them, I am convinced I get better sleep when I take them. I could add less anxiety and more, but better sleep alone could account for other benefits.
