Common symptoms and the nutrient gaps behind them
By Vita · fact-checked against NIH ODS
Everyday symptoms like tiredness, hair loss, brittle nails or cramps often have a nutritional thread you can act on. Each page below answers the question, names the vitamins and minerals most likely behind it — the same ones the free Vitaminico check looks at first — tells you what to eat, and shows how to confirm it with your clinician. These pages are educational, not a diagnosis.
