Minerals are natural elements found in the earth that the body uses to function properly. Unlike vitamins, minerals aren’t made by plants or animals—they come from soil, rocks, and water, and enter our bodies through food and the environment. Once inside the body, they make energy production possible.
Minerals are often referred to as the “body’s spark plugs.” They help enzymes turn food into energy, allow nerves to send signals, muscles to contract, and hormones secretion. Calcium helps cells fire and muscles move, magnesium allows those signals to relax and reset, sodium and potassium create electrical gradients, and trace minerals fine-tune thousands of tiny reactions happening every second.
Stress, sweating, illness, poor digestion, and highly processed foods all drain mineral reserves over time. When minerals are low or out of balance, the body cannot maintain healthy blood sugar, hormone regulation, and cellular energy.
Minerals:
- Act as essential cofactors for enzymes involved in oxidative metabolism and ATP production
- Regulate cellular hydration, membrane potential, and electrical signaling
- Help stabilize blood sugar by supporting insulin sensitivity and reducing stress-hormone signaling
- Support mitochondrial respiration and efficient energy transfer
- Protect against oxidative damage by activating antioxidant enzymes
- Enable phase I and phase II detoxification pathways, including the metabolism of estrogen, ammonia, and heavy metals
- Maintain tissue oxygenation, circulation, and balanced immune function
Key causes of mineral depletion:
- Chronic stress and elevated cortisol, which increase urinary mineral loss
- High intake of seed oils and polyunsaturated fats, which raise oxidative stress and mineral demand
- Low stomach acid, reducing the absorption of minerals like magnesium, calcium, zinc, and iron
- Poor protein intake, limiting mineral transport, binding, and utilization
- Excessive iron intake or iron overload, which interferes with copper, zinc, and magnesium balance
- Glyphosate and other environmental toxins that bind minerals and disrupt gut absorption
- Overuse of diuretics, proton pump inhibitors (PPIs), and laxatives
- Chronic inflammation and infection, which shift minerals away from circulation and into stress pathways
- Heavy sweating without mineral replacement (heat, exercise, sauna use)
- Gut dysbiosis or intestinal damage, impairing absorption
- Poor sleep and circadian disruption, increasing stress hormone–driven mineral loss
Deficiency can exist even with a “healthy” diet, especially when absorption, retention, or balance is impaired.
MAGNESIUM
Function: Magnesium is essential for energy production, serving as a cofactor in over 300 enzymatic reactions. It binds to ATP to make cellular energy usable, supports nervous system stability, helps regulate blood sugar, promotes muscle relaxation, and plays a role in healthy estrogen metabolism and detoxification.
Deficiency signs: Anxiety, insomnia, muscle cramps, constipation, palpitations, headaches.
Food sources: Fruit, dairy, potatoes, leafy greens, well-cooked vegetables.
Low magnesium increases stress hormones, inflammation, and directly lowers ATP. Cancer patients are frequently deficient.
POTASSIUM
Function: Potassium is essential for maintaining cellular hydration and electrical charge. It regulates nerve signaling and muscle contraction by sustaining the cell’s membrane potential, supports healthy blood pressure through sodium–potassium balance, and plays a key role in glucose utilization by facilitating insulin sensitivity and carbohydrate uptake into cells.
Deficiency signs: Fatigue, weakness, palpitations, anxiety, constipation, poor glucose metabolism and blood sugar imbalances.
Food sources: Fruit, fruit juice, potatoes, coconut water, dairy.
Low potassium promotes cellular dehydration and stress signaling.
SODIUM
Function: Sodium is strongly anti-stress. It maintains blood volume and circulation, supports adrenal output, and prevents excessive adrenaline and cortisol release. Sodium improves glucose delivery to tissues and supports thyroid hormone action by maintaining proper cellular electrical gradients.
Deficiency signs: Dizziness, fatigue, salt cravings, low blood pressure, high stress hormones.
Food sources: Sea salt, salted foods, broth, cheese.
Adequate sodium supports thyroid function and reduces stress hormones.
CALCIUM
Function: Calcium helps lower the stress response by suppressing parathyroid hormone and reducing excess adrenaline and cortisol. It stabilizes nerve signaling, supports restful sleep, and improves metabolic efficiency when paired with adequate magnesium and vitamin D. Proper calcium balance supports thyroid function, glucose regulation, and long-term tissue stability.
Deficiency signs: Muscle spasms, brittle nails, dental issues.
Food sources: Dairy, cheese, yogurt, milk, bone broth, leafy greens, broccoli, mineral water.
Excess calcium without magnesium and vitamin K can promote soft-tissue calcification.
PHOSPHORUS
Function: Phosphorus is a core component of ATP and cell membranes, making it central to energy transfer and carbohydrate metabolism. It supports insulin signaling, and acid–base balance.
Deficiency signs: Weakness, bone pain, poor exercise tolerance.
Food sources: Milk, cheese, meat, fish, grains.
Critical for mitochondrial energy generation.
ZINC
Function: Zinc supports hormone synthesis and receptor sensitivity, including insulin, thyroid hormone, and reproductive hormones. It improves glucose control, immune balance, and antioxidant defense, and is essential for proper stress recovery and tissue repair.
Deficiency signs: Frequent infections, hair loss, poor wound healing, low appetite.
Food sources: Red meat, shellfish, dairy.
Zinc deficiency impairs immune surveillance and tissue repair.
COPPER
Function: Copper supports mitochondrial respiration and oxygen utilization, reducing reliance on stress metabolism. It is required for iron metabolism, thyroid hormone function, nervous system health, and maintaining balanced estrogen levels.
Deficiency signs: Anemia, fatigue, connective tissue weakness.
Food sources: Shellfish, liver, cocoa, potatoes.
Copper must balance zinc. Excess zinc can induce copper deficiency
IRON
Function: Iron is required for oxygen transport, mitochondrial energy production, and thyroid hormone synthesis. In adequate amounts, it supports tissue oxygenation and efficient metabolism. When iron accumulates in excess, however, it increases oxidative stress, interferes with copper and zinc balance, and can amplify inflammation and insulin resistance. Proper iron balance depends on absorption, storage, and regulation—not supplementation alone.
Deficiency signs: Fatigue, cold intolerance, shortness of breath.
Food sources: Red meat, liver, leafy greens, fortified grains.
Excess iron promotes oxidative stress. Supplement only when clearly indicated, and focus on food sources if needed.
IODINE
Function: Iodine is required for thyroid hormone production, which sets metabolic rate, temperature, and carbohydrate utilization. It also supports breast and reproductive tissue health and helps regulate estrogen responsiveness.
Deficiency signs: Cold intolerance, fatigue, breast tenderness.
Food sources: Dairy, seafood, iodized salt.
Adequate iodine supports metabolic rate and tissue differentiation. However, excessive iodine can impair thyroid function via the Wolff-Chaikoff Effect.
SELENIUM
Function: Selenium is essential for converting thyroid hormone T4 into active T3, directly influencing metabolic rate and energy availability. It is a critical component of antioxidant enzymes (including glutathione peroxidases and thioredoxin reductases), which protect mitochondria and cell membranes from oxidative damage. Selenium helps regulate immune activity, limit inflammatory stress, and preserve metabolic function.
Deficiency signs: Fatigue, thyroid dysfunction, poor immunity.
Food sources: Seafood, eggs, dairy.
Supports glutathione activity and cellular defense.
MANGANESE
Function: Manganese activates enzymes involved in glucose metabolism, antioxidant defense, and mitochondrial function. It supports insulin sensitivity and helps protect cells from oxidative stress during energy production.
Deficiency signs: Joint pain, poor wound healing.
Food sources: Blueberries, maple syrup, tea, whole grains, leafy greens, etc.
MOLYBDENUM
Function: Molybdenum supports detoxification enzymes that clear sulfur compounds, aldehydes, and ammonia, reducing metabolic and hormonal stress on the liver.
Deficiency signs: Chemical sensitivity, headaches.
Food sources: Milk, legumes, grains, beef liver.
A few things to know:
- Minerals operate as a network. No mineral works alone.
- High calcium without magnesium stiffens tissues.
- High zinc without copper disrupts iron balance.
- Low sodium increases stress hormones.
- Low potassium impairs glucose metabolism.
- Balanced intake is more beneficial than megadoses.
A few things to do to support healthy mineral balance:
