Mineral Deficiency & Toxicity in the Body - Chapter Summary
Minerals ensure our bodies function properly, but must be consumed appropriately to avoid serious problems. The lessons in this chapter examine the impact of mineral deficiency and toxicity in our bodies. Learn about various types of minerals the body needs, and examine how we're impacted by a mineral imbalance. Once you've completed this chapter, you will be able to:
- Discuss the electrolyte deficiency and toxicity symptoms of sodium, potassium and chloride
- Describe the roles of calcium and phosphorus in the body and symptoms tied to their deficiency and toxicity
- Examine the importance of magnesium and sulfur and how their deficiency and toxicity impact our bodies
- Explain the deficiency and toxicity symptoms of iron, zinc, iodine, copper and selenium
- Detail the roles of chromium, fluoride, manganese and molybdenum in the body and symptoms tied to their deficiency and toxicity
Each lesson in this chapter is available in a video or transcript format. Watch the videos to learn about mineral deficiency and toxicity in the body with help from fun visual effects. Review and print full transcripts if you prefer to read your lessons or want to take additional notes and highlight key details. With each lesson is a short quiz you can use to assess your knowledge of concepts covered. A chapter exam is also available to reinforce lesson concepts.

6. Magnesium Deficiency & Toxicity Symptoms
Magnesium is a major mineral needed by your body for a number of processes. Learn how symptoms such as muscle twitches, depression, fatigue and numbness are related to magnesium deficiency, as well as the effects of magnesium toxicity, in this lesson.
7. Chromium: Deficiency & Toxicity Symptoms
Chromium is a trace mineral that helps maintain normal blood glucose levels in your body. Learn who is at risk of deficiency and how a deficiency can lead to diabetes-like symptoms, as well as the issues, if any, related to chromium toxicity in this lesson.
8. Phosphorus Deficiency & Toxicity Symptoms
Phosphorus is a mineral needed by your body for strong bones and teeth and other body processes. Learn about the functions and sources of this major mineral, as well as what happens to your body if there is too little or too much, in this lesson.
9. Iron: Deficiency & Toxicity Symptoms
Iron is a trace mineral that your body gets from a variety of animal and plant foods. It has many functions, including making hemoglobin. Learn how low iron can lead to iron deficiency anemia and the health consequences associated with iron toxicity.
10. Zinc: Deficiency & Toxicity Symptoms
In this lesson, you'll learn about zinc, which is a trace mineral that is needed for a number of functions in your body. Learn how a zinc deficiency can negatively impact your health and impair your immune function. Also, learn about the signs and symptoms associated with zinc toxicity.
11. Iodine: Deficiency & Toxicity Symptoms
