Minerals are inorganic nutrients essential for bone health, muscle function, electrolyte balance, energy production, and hundreds of biochemical processes. Unlike vitamins, minerals come directly from the earth — via plants, water, and animals — and cannot be synthesised by the body.
Minerals are the silent workhorses of human biology. While vitamins get more attention, minerals perform roles that are no less critical: calcium and phosphorus build the skeleton; sodium, potassium, and chloride regulate every heartbeat and nerve impulse; magnesium participates in over 300 enzymatic reactions; and sulfur structures the proteins that make up your hair, skin, and connective tissue.
Unlike vitamins, which the body can sometimes synthesise (vitamin D from sunlight, niacin from tryptophan), minerals must come entirely from food and water. The modern processed-food diet has disrupted mineral balance in ways our ancestors didn't face — excess sodium, insufficient potassium, magnesium depleted by chronic stress, and phosphate additives in ultra-processed foods loading the kidneys.
Our mineral guides cut through the noise: evidence-based content on what each mineral does, how much you need, where to find it, and when to be concerned — without overstating risks or promoting unnecessary supplementation.
Required in quantities above 100mg/day — calcium, magnesium, potassium, sodium, phosphorus, chloride, and sulfur. These are the body's primary structural and electrolyte minerals.
Required in much smaller quantities but no less essential — iron, zinc, copper, manganese, iodine, and selenium. Each plays highly specific enzymatic and hormonal roles.
Fluoride and boron are not classified as essential in the traditional sense, yet both have significant and well-researched biological roles — in dental health and bone/hormone metabolism respectively.
Each guide covers benefits, daily requirements, deficiency signs, food sources, and interactive tools — organised by category.
Required in amounts above 100mg/day — foundational for bone, muscle, electrolyte, and energy systems.
Essential for strong bones and teeth, muscle contractions, and nerve function. Vitamin D is required for efficient absorption.
Critical for energy production, sleep quality, stress regulation, and muscle relaxation. Highly depleted by modern stress and processed diets.
Counteracts sodium's blood pressure-raising effects, supports muscle function, and protects cardiovascular health. 97% of adults don't get enough.
Essential for fluid balance and nerve signalling, but nearly all Western adults consume too much. Understanding the sodium-potassium balance is key.
Works with calcium to build bone structure and produces ATP — the energy currency of every cell. Deficiency is rare; excess from food additives is the modern concern.
The primary extracellular anion — pairs with sodium to regulate fluid balance and enables stomach acid (HCl) production for digestion.
Component of essential amino acids (cysteine, methionine), required for glutathione synthesis, and supports skin, hair, nail, and joint health.
Required in microgram to milligram quantities — essential for enzymes, hormones, antioxidants, and oxygen transport.
Essential for haemoglobin and oxygen transport. Iron deficiency is the world's most prevalent nutritional disorder — particularly impacting women, athletes, and plant-based eaters.
Essential for immune defence, skin healing, and hormone balance. Zinc deficiency affects 17% of the global population — particularly impacting plant-based eaters, athletes, and men.
Required for iron transport, energy production, and nerve function. High zinc supplementation is the leading cause of copper deficiency — understanding their balance is critical.
Essential for mitochondrial antioxidant defence (Mn-SOD), bone matrix formation, and energy metabolism. Deficiency is rare — but this background mineral quietly supports hundreds of processes.
Essential for thyroid hormone production (T3/T4). Iodine deficiency is the world's leading preventable cause of intellectual disability — and one of the most common deficiencies in plant-based diets.
Essential for thyroid hormone activation (T4→T3), GPx antioxidant defence, and immune regulation. 1–2 Brazil nuts per day meets the daily requirement. Both deficiency and excess matter.
Not classified as traditionally essential, but with well-documented roles in dental health, bone metabolism, and hormone balance.
Essential for tooth enamel strengthening and cavity prevention. Found in fluoridated water and toothpaste — most people don't need supplements. Both deficiency and excess have consequences.
Not officially essential, yet boron supports free testosterone (via SHBG inhibition), bone mineral metabolism, and cognitive function. Found almost exclusively in plant foods — fruits, nuts, and legumes.
Modern diets create predictable mineral shortfalls. Understanding which minerals are most likely to be low in your diet is the first step.
97% of adults globally fall below recommended intake — almost entirely because of low fruit, vegetable, and legume consumption. This single mineral gap is the most consistent nutritional problem in Western diets.
Read guide →Approximately 48% of US adults consume below the RDA. Chronic stress, alcohol, and processed-food diets all deplete magnesium faster than typical dietary sources restore it.
Read guide →Deficiency risk increases sharply after 50, particularly in post-menopausal women. Calcium requirements increase as absorption efficiency declines — a combination that drives significant bone loss if not addressed.
Read guide →Essential minerals don't operate in isolation — they form an interconnected system. The sodium-potassium balance determines blood pressure; the calcium-phosphorus ratio determines bone quality; magnesium is required for proper calcium metabolism and vitamin D activation; chloride pairs with sodium in every electrolyte exchange. Understanding these relationships is as important as knowing individual mineral targets.
