Critical Nutritional Foundations: Mineral Balance
CRITICAL NUTRITIONAL FOUNDATIONS IV
Mineral Balance 101
by Ani Bajaj (NTP, RHP-1, FBCS)
Minerals are often considered foundational to nutrition therapy because they’re required for many of the body’s most basic processes—and deficiencies can create ripple effects across multiple systems.
“Minerals are like the backstage crew of the body—no one applauds them, but without them the whole show shuts down.”
They help enzymes function, they support structural health, they regulate fluid- balance and nerve signaling and they support hormones.
Modern diets can be lower in minerals due to highly processed foods, lower intake of whole/nutrient-dense foods, soil depletion concerns and digestive issues affecting absorption.
Did you know?
- Minerals make up about 4-5% of our body.
- Humans do not produce minerals; therefore, we must obtain them through our food and/or supplementation.
- Minerals are what remain as ash when plant or animal tissues are burned.
- Out of the 103 known minerals, at least 18 are necessary for good health.
Macrominerals are needed in large amounts while microminerals are needed in trace amounts. The trace amounts that are needed are just as important function-wise.
What are the Macrominerals?
Calcium / Chloride / Magnesium / Phosphorous / Potassium / Sulfur / Sodium
Calcium is the most abundant out of all the minerals in the body!
Most of it is stored in bones and teeth.
Calcium: Mineralizes bone and teeth, especially during times of rapid growth, needed for muscle contraction, as in muscular activity and regulating heartbeat. Influences nerve and cell membranes and the release of neurotransmitters. It is necessary for cell division and essential in blood coagulation.
Note: Folks may get enough calcium (e.g. dairy/leafy greens) in their diet, but they are missing the co-factors that allow the body to use/absorb it!
There are 6 major co-factors that impact the absorption and use of calcium within the body:
- Hormonal Function
- Other Minerals (Magnesium / Phosphorus / Boron / Zinc / Manganese / Copper)
- Fatty Acids
- Hydration (water and electrolytes)
- Vitamins (D and K2)
- Digestion
Let’s look at some of the other Macrominerals!
Magnesium:
Facilitates as many as 300 enzymatic reactions. 60% of magnesium in body is found in the bone, 25% in muscle and the remainder in the fluids and soft tissue. Found in high concentrations in the mitochondria and heart.
Functions are: Structural integrity of teeth and bones / regulates contractility of heart muscle/ relaxes smooth muscle / necessary for essential fatty acid metabolism/ essential for protein synthesis.
Phosphorus:
Second most abundant mineral the body, after calcium. 80% of phosphorus in the body is found in the form of calcium phosphate crystals in the bone and teeth. Phosphorus levels are maintained by parathyroid hormone. A 1:1 intake of calcium to phosphorus is ideal for maximum absorption of calcium.
Functions are: Structural component of teeth and bones, essential part of ATP (body’s main energy molecule produced primarily in the mitochondria), essential component of nucleic acids of DNA and phospholipids that make up cellular membranes.
Potassium:
One of the most major intracellular minerals and electrolytes. Actively transported in and out of the cell. Increasing levels of aldosterone, an adrenal hormone, causes the excretion of potassium from the body.
Functions are: One of the major transport systems in the body via the sodium-potassium pump. Functions to maintain proper cellular fluid levels. Supports acid-base balance in body. Essential for nerve conduction and heart function.
What are the Microminerals?
Boron / Chromium / Cobalt / Copper / Germanium / Iron / Iodine / Lithium / Manganese / Molybdenum / Rubidium / Selenium / Silicon / Vanadium / Zinc
Let’s look at some of the Microminerals!
Zinc: Essential to produce stomach acid, important for the synthesis of cholesterol, fats and proteins, regulates release of vitamin A from the liver. Critical for cell growth and cellular replication of DNA. Essential for skin and bone integrity, necessary for prostate health, required for optimal function of the immune system. Essential co-factor for EFA (Essential Fatty Acid) metabolism and synthesis. Needed for taste perception.
Iodine: Essential for production of thyroid hormones and therefore required for normal thyroid function (thyroxine is 65% iodine). Required for cell respiration and production of energy as ATP. Needed for normal growth and development. Affects nerve and bone formation, and the condition of the skin, hair, nails and teeth.
Iron: Essential in the formation of hemoglobin, which carries oxygen molecules throughout the body, gives us our strength and look of good health! Iron helps power mitochondrial enzymes involved in ATP production, supports enzymes that metabolize amino acids, and plays a critical role in oxygen delivery through hemoglobin. Involved in the formation of tissue collagen and elastin. Helpful in the production of carnitine, an amino acid important for the utilization of fatty acids.
More about the roles of Minerals in the Body:
- Acting as cofactors for enzyme reaction
- Facilitating the transfer of nutrients across cell membranes
- Maintaining proper nerve conduction
- Contracting and relaxing muscles
- Regulating tissue growth
- Providing structural and functional support
Let’s break some of these down.
Enzymes require minerals to activate them: Many enzymes need mineral cofactors (often called cofactors or coenzymes when vitamins are involved) to function properly. Think of enzymes as workers and minerals as the tools that help them do their jobs efficiently. Without the right minerals, enzymes may work poorly—or not at all. For example, Magnesium + ATP enzymes (energy production): Magnesium helps activate enzymes involved in ATP production.
Facilitating the transfer of nutrients across cell membranes: There are mineral pumps within the lipid bi-layer of the cell membrane like the sodium-potassium pump, which is a transport mechanism that moves sodium and potassium ions in and out of the cell.
Maintaining proper nerve conduction: Calcium and magnesium are critical for proper nerve conduction and muscle function. Calcium helps stimulate nerve signaling and muscle contraction, while magnesium helps regulate nerve activity and supports muscle relaxation. Together, they maintain proper neuromuscular balance.
Regulating tissue growth: Iodine supports metabolic health and regulates tissue growth and development by enabling the production of thyroid hormones, which influence cellular energy, repair, and growth processes throughout the body.
Minerals interact with one another in important ways - some have synergistic relationships (they enhance each other’s function), while others have antagonistic relationships (they can compete with or inhibit each other when imbalanced).
Synergists
Iron and Copper – Copper helps the body properly absorb, transport, and utilize iron. Iron gets a lot of attention for energy and anemia—but copper is one of the quiet players helping iron actually do its job.
Magnesium and Potassium- They work together to regulate cellular energy, fluid balance, nerve signaling, muscle function, and heart rhythm.
Calcium, Magnesium and Phosphorus – they work together in bone structure, energy production, muscle function, and cellular signaling.
Antagonists (and Synergists)
Zinc and Copper - Antagonistic in absorption, synergistic in function. High zinc intake can reduce copper absorption because zinc increases production of a protein in the intestines called metallothionein. Metallothionein binds copper strongly and can trap it in intestinal cells, which then get shed—reducing how much copper enters circulation. This is why long-term high-dose zinc supplementation can contribute to copper deficiency. However, together they support immune function, antioxidant defense, energy production and tissue repair.
Sodium and Potassium- Sodium and Potassium work in opposition to maintain fluid balance, nerve signaling, muscle contraction, and heart rhythm. Their relationship is often described as antagonistic, but that doesn’t mean one is “bad”—it means they must remain in balance. Sodium is primarily found outside the cell, while potassium is primarily found inside the cell. Through the Sodium- potassium pump, they move in opposite directions to create the electrical gradients needed for proper nerve communication and muscle function. When sodium intake is consistently very high - especially from processed foods - the kidneys may excrete more potassium, which can contribute to imbalance in some individuals.
Calcium and Magnesium- Calcium and magnesium are often described as physiological antagonists because they frequently have opposing effects in the body—yet they also work together. It’s more accurate to think of them as a balancing pair rather than “good vs bad.” They work together for bone health, nerve conduction, cardiovascular health and energy metabolism. At the cellular level, they often have opposing actions: Calcium promotes muscle contraction, and magnesium helps muscles relax. Calcium can increase excitability / signaling and magnesium helps regulate calm excessive stimulation. Magnesium also helps regulate calcium flow into cells.
These are great examples of why mineral balance is complex!! The same two minerals can compete in one pathway while supporting similar physiological systems elsewhere.
Some therapeutic foods for Minerals! (*Bio-individual dietary needs may vary).
Almonds: High in calcium, phosphorus, magnesium, manganese, high in zinc (best to soak almonds before eating for more nutritional value).
Sea vegetables like seaweed: High in iodine – necessary for production of thyroid hormones
Salmon/Sardines and Mackerel - with the bones: Good source of calcium
Brazil nuts: Selenium is necessary for the conversion of T4 to the active thyroid hormone T3
Cashews: Contain high levels of magnesium
Root vegetables (e.g. potatoes, beets, carrots)- Contain Silica – important for collagen formation and for connective tissue’s elasticity and resilience. It also regulates calcium placement in bone and tissue.
Avocado – Potassium – helps regulate water balance and distribution; kidney and adrenal function; muscle and nerve function; heart function
Yoghurt: High in calcium, phosphorus
Beef: High in iron and phosphorus
Chicken: High in phosphorus, potassium
Lentils: High in phosphorus, sulfur, iron and molybdenum
Pumpkin seeds: High in zinc
Oysters: High in zinc
Minerals are foundational, but they’re also relational. The body doesn’t use nutrients in isolation—it uses them in networks!
