Still feeling tired, weakened resilience, or sluggish despite your efforts to live healthier?
Minerals fuel energy, immunity, bone strength, muscle function, and overall wellness—explore how they fit into our complete Nutrition Guide.
This guide reveals how essential minerals fuel daily vitality to help your body perform at its best.
What Are Minerals?
Minerals are essential nutrients from soil and water that support growth, repair, and everyday body functions through the foods you eat.
NIH highlights that minerals are essential for bone health, heart function, energy production, and immune support.
Why it matters:
Your body relies on essential nutrients to support strong bones and teeth, healthy muscles and nerves, oxygen transport, hormone production, fluid balance, energy metabolism, and immune function.
What works for me:
Minerals help my body build strong bones, healthy muscles and nerves, fluid balance, energy production, and essential body functions.
How to start:
- Eat more whole foods.
- Include vegetables at every meal.
- Choose nuts and seeds for snacks.
- Add legumes several times weekly.
- Limit heavily processed foods.
Understanding Major Minerals vs. Trace Minerals
Major and trace minerals, though needed in different amounts, work together to support energy, immunity, muscles, and overall health, making a varied whole-food diet the best way to get enough.
Major minerals: Nutrients your body requires in greater amounts to function properly.
- Calcium
- Magnesium
- Potassium
- Sodium
- Phosphorus
- Chloride
- Sulfur
Trace minerals: You need these in smaller amounts, but they remain critical.
- Iron
- Zinc
- Copper

I balance both major and trace minerals for stronger bones, healthy muscles, nerve function, energy, and overall wellness.
How to start:
- Eat a variety of foods.
- Rotate fruits and vegetables weekly.
- Include seafood when possible.
