Your Daily Dose of Nutrition Truth
Nutrigenomics companies are charging hundreds of dollars to tell you which supplements your DNA 'needs' — but the science behind most of those recommendations is thinner than the cardstock your report gets printed on. We broke down what genetic testing can and can't tell you about your diet, and how to know when you're buying real insight versus expensive guesswork.
You're taking your supplements every morning like clockwork — but some of those pills are running interference on each other before they even make it into your bloodstream. From zinc and copper to green tea and iron, these sneaky nutrient rivalries are more common than you'd expect, and most supplement labels won't breathe a word about them.
That bottle of vitamin C you forgot about isn't necessarily dangerous — but it might not be doing much for you either. The rules around supplement expiration dates are murkier than most people realize, and some manufacturers are quietly using them to keep you buying more.

Tossing all your vitamins into one hand and washing them down with your morning OJ feels efficient — but your body doesn't see it that way.

Here's what the science says about when to take what.
That mid-afternoon wall you keep hitting? Turns out caffeine timing is probably the least of your worries. New research is pointing fingers at blood sugar swings, what you ate for lunch, and your body's own internal clock — and the fixes are simpler than you'd think.
Conventional wisdom says cut off caffeine by noon if you want decent sleep. But newer research on metabolism, genetics, and adenosine biology tells a more complicated — and honestly more hopeful — story. Your afternoon coffee habit might not be the villain you've been told it is.
While the nootropic industry keeps pushing $200 bottles of 14-ingredient blends, a two-supplement combo costing less than a latte has been quietly winning in clinical research for decades.

Here's what the science says and how to actually fix it.
Most people still think creatine is just a locker room staple for guys chasing bigger biceps. But a growing stack of peer-reviewed research says this well-studied compound may be one of the most underrated tools for protecting your brain as you age. Here's what the science actually shows — and why it might be time to rethink your assumptions.
Vitamin D deficiency is genuinely widespread in the US, but the answer isn't just to take more of it.

Here's what your lab results mean and how to find your personal sweet spot.
Magnesium is one of the best-selling sleep supplements in the US, but millions of people are buying the wrong form and wondering why they feel more alert than ever at bedtime.
