A Complete Guide to Symptoms, Causes, and How to Restore Balance Naturally
Minerals are essential nutrients your body needs in small but powerful amounts. They support everything from bone strength and heart rhythm to oxygen transport, nerve function, and immune defense.
The problem? Mineral deficiencies often develop slowly and show up as subtle symptoms — fatigue, mood changes, muscle cramps, or brittle nails — that are easy to ignore.
This comprehensive guide explains the warning signs of vital mineral deficiencies, who is at risk, and how to restore healthy levels safely.
