Nutrient guides
Short educational pages on vitamins and minerals people often under-eat, with food sources and cautious symptom associations. Not a diagnosis.
These guides summarize what public education sources (especially NIH ODS fact sheets) say about common nutrients. Use them to learn food sources and patterns worth noticing, then track what you actually eat.
CalBuddy can surface micronutrient gap glances while you log meals. A gap in the app is a journaling signal, not a blood test.
Primary education source family: NIH Office of Dietary Supplements fact sheets.
