Every Mineral Your Body Needs Explained

Main Ideas

The video explains 16 minerals, their roles in the body, possible signs of deficiency, and common food sources. Its central message is that minerals support essential processes—from carrying oxygen and producing energy to maintaining bones, nerves, muscles, and fluid balance. Both too little and, in some cases, too much can cause problems.

Minerals Covered

• Iron — carries oxygen

  • Iron is part of hemoglobin, which carries oxygen through the blood.
  • Low iron may cause tiredness, weakness, dizziness, feeling cold, and difficulty concentrating.
  • Sources include beef, liver, beans, lentils, spinach, and fortified cereals. Iron from meat is generally absorbed more readily than iron from plants.

• Calcium — supports bones, teeth, and muscle function

  • Most of the body’s calcium is stored in bones and teeth; the rest helps muscles contract and nerves send signals.
  • If dietary calcium is insufficient, the body may draw it from bones, weakening them over time.
  • Sources include dairy products, fortified plant milks, almonds, and leafy greens. Vitamin D helps the body absorb calcium.

• Magnesium — supports many body processes

  • Magnesium is involved in hundreds of enzyme reactions, including energy production, muscle and nerve function, and maintaining a steady heartbeat.
  • Low levels may be associated with cramps, stress, sleep trouble, and fatigue. Severe deficiency can affect heart rhythm.
  • Sources include nuts, seeds, whole grains, dark chocolate, and leafy greens. Magnesium also works with calcium and potassium in muscle function.

• Potassium — helps balance fluids and electrical signals

  • Potassium works with sodium to regulate fluid balance, nerves, muscles, heartbeat, and blood pressure.
  • Low levels may cause weakness, fatigue, cramps, or an abnormal-feeling heartbeat. Severe cases can be dangerous.
  • Sources include bananas, potatoes, beans, oranges, tomatoes, and leafy greens.

• Sodium — supports nerves and fluid balance

  • Sodium helps nerves transmit signals and works with potassium in muscle function and fluid balance.
  • Too much can cause the body to retain water, potentially raising blood pressure and straining the heart. Too little may cause dizziness, confusion, weakness, and muscle twitching.
  • The video’s takeaway is not to eliminate sodium, but to avoid excess, especially from processed and packaged foods.

• Zinc — supports repair and immunity

  • Zinc helps repair cells, heal wounds, support immune function, and maintain taste and smell.
  • Low levels may contribute to slow healing, hair loss, weakened immunity, and reduced taste or smell. Long-term deficiency in children can affect growth.
  • Sources include meat, shellfish, beans, nuts, seeds, and whole grains. The body does not store much zinc, so regular intake matters.

• Iodine — helps the thyroid produce hormones

  • The thyroid uses iodine to make hormones involved in metabolism, energy, temperature regulation, and growth.
  • Deficiency may cause fatigue, weight gain, low body temperature, a puffy face, and brain fog. Severe deficiency can cause goiter.
  • Sources include iodized salt, seaweed, fish, dairy, and eggs. Only a small amount is needed.

• Selenium — helps protect cells

  • Selenium supports antioxidant defenses, the thyroid, and the immune system.
  • Low levels may be associated with fatigue and weakened immunity. Severe deficiency can affect the heart or thyroid, and excess selenium can also be harmful.
  • Sources include Brazil nuts, fish, eggs, whole grains, and meat. One Brazil nut may provide most of a day’s selenium needs.

• Copper — helps the body use iron

  • Copper supports iron use, red blood cell formation, connective tissue, immunity, and brain development.
  • Deficiency may cause anemia, weak bones, or problems with memory or coordination. Too much can be toxic, so the body tightly regulates it.
  • Sources include shellfish, whole grains, nuts, beans, and organ meats. Deficiency is uncommon unless absorption is impaired.

• Phosphorus — supports bones and energy

  • Phosphorus works with calcium in bones and teeth and is used by cells to produce and store energy.
  • Low levels are uncommon but may cause weak muscles, bone pain, or fatigue. Excess, often associated with processed foods and sodas, may disrupt calcium balance.
  • Sources include meat, dairy, nuts, beans, and whole grains.

• Manganese — helps metabolism

  • Manganese assists with processing carbohydrates, proteins, and fats. It also contributes to bone formation and cell protection.
  • Deficiency is rare but may affect bones, growth, or metabolism. Excess—particularly from contaminated water or workplace exposure—can harm the nervous system.
  • Sources include nuts, whole grains, leafy greens, and tea.

• Chromium — assists with blood sugar regulation

  • Chromium helps the body use insulin and helps cells take up glucose for energy.
  • Deficiency is uncommon; low levels may be linked to poor blood sugar control, fatigue, or cravings.
  • Sources include whole grains, broccoli, potatoes, nuts, and meat. The video cautions that chromium supplements are not a fat-loss miracle and that reported effects are small.

• Fluoride — helps protect tooth enamel

  • Fluoride strengthens enamel and helps resist tooth decay.
  • Low intake may contribute to weaker enamel and more cavities. Too much may discolor teeth and, rarely, affect bones.
  • Sources include toothpaste, fluoridated water, tea, and some seafood.

• Molybdenum — supports enzyme activity

  • This trace mineral helps enzymes process certain waste products and substances, including sulfur-related compounds.
  • Deficiency is extremely rare. The video says it can interfere with processing some amino acids and toxins. Excess may cause joint problems.
  • Sources include beans, lentils, whole grains, and nuts.

• Chloride — helps regulate fluids and stomach acidity

  • Chloride works with sodium and potassium to balance body fluids and helps maintain stomach acidity for digestion.
  • Low levels are uncommon but may occur with severe vomiting, dehydration, or certain medications. Possible signs include weakness, dehydration, and dizziness.
  • Sources include table salt, seaweed, tomatoes, celery, and olives. Because chloride often comes with sodium, intake can also be excessive.

• Sulfur — helps build and protect proteins

  • Sulfur contributes to proteins such as keratin, found in hair, skin, and nails, and supports the liver’s processing of waste.
  • Deficiency is rare; the video associates it with weak hair, brittle nails, or slow healing.
  • Sources include meat, fish, eggs, garlic, onions, and legumes. Sulfur is commonly present in protein-rich foods.

Overall Takeaway

A varied diet supplies many of these minerals, but the body’s needs differ: some are required in larger amounts, while others are needed only in trace amounts. The video repeatedly emphasizes balance—deficiency can impair bodily functions, while excess can also be harmful.
