Minerals Explained: Frequently Asked Questions

Minerals are inorganic elements found in soil and water, which are absorbed by plants or eaten by animals. Your body needs them for bone structure, fluid balance, and nerve transmission.

Macrominerals (Calcium, Potassium, Sodium, Magnesium) are needed in larger amounts. Trace minerals (Iron, Zinc, Iodine, Selenium) are required in very small amounts, but are still vital.

99% of your body's calcium is in your bones and teeth. It keeps them strong. The remaining 1% is crucial for muscle contraction and heart function.

It is necessary for survival (fluid balance, nerve signals). However, modern diets contain excessive processed sodium, which can raise blood pressure. The key is moderation, not elimination, especially for athletes who sweat it out.

Yes. Magnesium plays a role in relaxing the nervous system and muscles. Deficiency is common and can lead to insomnia or restlessness. Supplements are often recommended for sleep support.

A lack of iron impairs hemoglobin's ability to carry oxygen in the blood. Symptoms include extreme fatigue, pale skin, and shortness of breath. Women are more prone to this due to menstruation.

Electrolytes are minerals (Sodium, Potassium, Magnesium, Calcium) that carry an electric charge. They control muscle contractions and hydration. You lose them when you sweat.

Zinc is critical for the development and function of immune cells. Taking zinc during the early stages of a cold may reduce its duration.

Bananas are famous, but potatoes, spinach, avocados, and coconut water often contain even more potassium.

Your thyroid gland uses iodine to make hormones that control metabolism. Deficiency can lead to goiter (enlarged thyroid) and hypothyroidism.

Yes. Cramps are often caused by an imbalance of electrolytes, specifically magnesium, potassium, or sodium dehydration.

Anti-nutrients like phytates (in grains) or oxalates (in spinach) can bind to minerals and reduce absorption. However, vitamin C enhances iron absorption. A varied diet usually balances this out.
