Salt & Minerals

Minerals are basic, but they are not minor. Sodium, potassium, magnesium, calcium, iodine, zinc, selenium, and trace minerals govern hydration, blood pressure, thyroid function, energy production, nerve signalling, and muscle contraction. Blanket low-salt advice can be unhelpful for some people, especially those who train hard, eat low carb, sweat heavily, or feel dizzy and depleted. This chapter rebuilds the mineral conversation from first principles.

6 takeaways from this chapter.

• Why sodium is essential for blood volume, nerve signalling, and performance
• How potassium, magnesium, calcium, and trace minerals work together
• When low-salt advice can backfire and when salt restriction is medically important
• The mineral patterns behind cramps, fatigue, headaches, poor sleep, and cravings
• How diet, hydration, training, and stress change mineral requirements
• How mitochondrial and gut-support strategies depend on basic mineral sufficiency

Anyone dealing with fatigue, cramps, headaches, dizziness, low-carb symptoms, heavy sweating, or confusing blood-pressure advice. It is also for athletes, sauna users, and people who want the basics of mineral status handled properly.
