🌱 Homocysteine: The Tiny Molecule With a Big Story
Minerals are inorganic elements absorbed from soil and water, then passed into plants and animals. Unlike vitamins, which are organic, minerals are structural and functional building blocks. Your body cannot produce them, so they must come from food or supplements.
Bone and Teeth Strength: Calcium, phosphorus, and magnesium form the foundation of skeletal health.
Nerve and Muscle Function: Sodium, potassium, and chloride regulate electrical impulses and muscle contractions.
Energy Production: Iron carries oxygen in hemoglobin, while magnesium supports enzyme activity.
Immune Defense: Zinc and selenium boost immunity and help fight oxidative stress.
Hormone Regulation: Iodine is critical for thyroid hormones, while chromium supports insulin function.
Most people can meet mineral needs through a balanced diet rich in plant-based foods:
Leafy greens (spinach, kale) → magnesium, calcium
Legumes and beans → iron, zinc
Nuts and seeds (pumpkin, sesame, almonds) → magnesium, selenium
Whole grains → manganese, chromium
Seaweed and iodized salt → iodine
Fruits (bananas, oranges) → potassium
Cooking methods also matter—using a cast iron skillet can add small amounts of iron to food.
While food should be the first source, supplements can help bridge gaps, especially for vegetarians, vegans, or those with medical conditions. Common options include:
| Mineral | Supplement Form | When Needed |
|---|---|---|
| Calcium | Calcium citrate or carbonate | Low dairy intake, osteoporosis risk |
| Iron | Ferrous sulfate or gluconate | Anemia, heavy menstruation, plant-based diets |
| Magnesium | Magnesium citrate or glycinate | Muscle cramps, stress, poor sleep |
| Zinc | Zinc gluconate or picolinate | Frequent infections, poor wound healing |
| Iodine | Potassium iodide (in multivitamins) | Low iodine diet, thyroid support |
| Selenium | Selenomethionine | Low soil selenium regions |
⚠️ Important: Excess supplementation can be harmful. For example, too much iron can damage organs, and excess calcium may cause kidney stones. Always consult a healthcare professional before starting supplements.
Minerals are the silent powerhouses of health—supporting bones, energy, immunity, and hormones. A varied, plant-rich diet usually covers your needs, but supplements can help if gaps remain. Think of minerals as the body’s “spark plugs”: small but vital for keeping everything running smoothly.
