Nutritional deficiencies can cause a wide range of symptoms, affecting energy levels, skin, hair, nails, cognitive function, and overall health. Below is a detailed table linking specific deficiencies to common symptoms and recommended food sources or supplements.

How to Use This Table:
✅ Match symptoms to a deficiency and check food sources before considering supplements.
✅ Combine vitamins & minerals wisely (e.g., Vitamin D + K2 + Calcium for bone health).
✅ If in doubt, test your levels (blood tests for iron, B12, Vitamin D, etc.).
✅ Choose the right form of supplements (e.g., methylated B12 if you have absorption issues).
