Smart Supplements: Worth the Investment or Just Hype?

I’ve been looking into some of these so-called “smart” supplements that claim to enhance everything from focus to longevity. With my background in forensic accounting, I tend to question the real value behind flashy marketing. Are these products genuinely backed by solid science, or are we just paying for clever branding? I’m especially curious about the role of nanotechnology in some formulas does it actually improve absorption, or is it more of a buzzword? What’s your take on whether these supplements deliver tangible benefits, or if they’re mostly placebo in a pricey bottle?
