That's how Longevitalis was born: I was sick of marketing-heavy, evidence-light brands, so I built the one I wished existed. Here I write about what actually moves the needle in sleep, longevity and biohacking — no fluff, with the science properly noted.","My obsession started with sleep. I'd been sleeping badly for years, functioning worse, and reading papers at 2 a.m. trying to figure out why. When I started applying protocols that actually had evidence behind them, everything changed: sleep, energy, mood and — yes — even my patience with Monday emails.\n\nWhat I write here is what would have saved me years of trial and error: concrete protocols, supplements that do what they say, and warnings about the ones that don't. If I recommend it, it's because I've tried it myself or there are several serious clinical trials behind it. Often both.\n\nWhen I'm not writing about the vagus nerve or arguing about magnesium doses, you'll find me training, sleeping (a lot, really) or trying to convince my mum that no, melatonin is not for every night of the week.","Spain",[2892],{"label":2893,"url":2894},"Store","https:\u002F\u002Flongevitalis.com",[2896,2897],{"path":869,"lang":860,"title":5},{"path":885,"lang":886,"title":887},1787309714703]
