Sometimes a supplement makes sense. Often your plate simply wins.

Magnesium is found in many everyday foods. How much you need according to EFSA, what research says about muscle cramps and where the upper limit for supplements lies.

In a Belgian winter your skin makes almost no vitamin D. What a blood test tells you, how much EFSA considers adequate and where the safe upper limit lies.

Less UV in October, often lower vitamin D status in winter. Literacy around Sciensano and the Superior Health Council — without a milligram prescription from a blog.

Keep creatine monohydrate boring: daily dose, food-first mindset, third-party tested — no TikTok loading.

Omega-3 via fatty fish stays the base; capsules are a backstop at low intake. Quality and dosing without hype or medical promises.

Magnesium and cramps: food first, supplements only with a real reason. Relativise TikTok claims without panic or guru dosing.

Melatonin and sleep blends rarely fix the cause. Caffeine, screens and rhythm first — a box only once the basics hold.
