Like vitamins, minerals are essential nutrients the body needs for everyday function. They support bones, muscles, nerves, fluid balance, oxygen transport, thyroid function, antioxidant defenses, metabolism, and much more.
Minerals are usually grouped into two categories: major minerals, also called macrominerals, and trace minerals. Major minerals are needed in larger amounts, while trace minerals are needed in smaller amounts. Both groups are important.
Food should be the first place to get minerals. A varied diet with protein foods, dairy or fortified alternatives, fruits, vegetables, whole grains, nuts, seeds, beans, and legumes can help support daily mineral intake. Supplements may be helpful when diet, life stage, health history, or a healthcare provider’s recommendation calls for additional support.
Major Minerals Cheat Sheet
Calcium
Calcium supports bones and teeth, muscle function, nerve signaling, and normal blood clotting. Food sources include dairy products, fortified milk alternatives, calcium-set tofu, sardines, canned salmon with bones, leafy greens, and fortified foods.
Phosphorus
Phosphorus works with calcium to support bones and teeth. It also plays a role in energy production and cell structure. Food sources include meat, poultry, fish, dairy, beans, lentils, nuts, seeds, and whole grains.
Magnesium
Magnesium supports muscle and nerve function, energy production, protein synthesis, bone health, and normal heart rhythm. Food sources include pumpkin seeds, almonds, cashews, spinach, black beans, whole grains, dark chocolate, and avocado.
Potassium
Potassium supports fluid balance, muscle function, nerve signaling, and cardiovascular wellness. Food sources include potatoes, sweet potatoes, bananas, oranges, tomatoes, beans, lentils, yogurt, spinach, and avocado.
Sodium and Chloride
Sodium and chloride help maintain fluid balance, nerve signaling, and muscle function. Most people get plenty of sodium from salt and packaged foods, so the goal is usually balance rather than adding more.
Sulfur
Sulfur is part of certain amino acids and proteins in the body. It is found naturally in protein-rich foods like meat, poultry, fish, eggs, beans, lentils, nuts, and seeds, as well as vegetables like onions, garlic, broccoli, cauliflower, and Brussels sprouts.
Trace Minerals Cheat Sheet
Iron
Iron supports red blood cell production and oxygen transport. Food sources include meat, poultry, seafood, beans, lentils, tofu, spinach, fortified cereals, and pumpkin seeds. Iron needs vary by sex, age, menstruation, pregnancy, diet pattern, and health status.
Zinc
Zinc supports immune function, wound healing, normal growth and development, DNA synthesis, and healthy cell division. Food sources include oysters, meat, poultry, beans, nuts, seeds, dairy products, and whole grains.
Iodine
Iodine supports thyroid hormone production, which plays a role in metabolism, growth, and development. Food sources include iodized salt, seafood, dairy products, eggs, and seaweed.
Selenium
Selenium supports antioxidant defenses, thyroid function, and immune health. Food sources include Brazil nuts, seafood, meat, poultry, eggs, dairy products, and whole grains.
Copper
Copper supports iron metabolism, connective tissue formation, energy production, nervous system function, and antioxidant defenses. Food sources include shellfish, nuts, seeds, organ meats, dark chocolate, beans, and whole grains.
Manganese
Manganese supports enzyme function, bone formation, metabolism, and antioxidant activity. Food sources include whole grains, nuts, leafy vegetables, tea, legumes, and some fruits.
Chromium
Chromium is involved in carbohydrate, fat, and protein metabolism and is often discussed for its role in supporting normal insulin function. Food sources may include whole grains, meats, fruits, vegetables, and some spices.
Molybdenum
Molybdenum supports enzyme systems involved in processing sulfur-containing amino acids and other compounds. Food sources include beans, lentils, grains, nuts, and organ meats.
Fluoride
Fluoride supports tooth mineralization and dental health. It is commonly found in fluoridated water, tea, seafood, and some dental products.
Other Minerals You May See on Supplement Labels
Boron
Boron is a trace element often discussed for its relationship to bone health, mineral metabolism, and vitamin D activity. There is no established RDA for boron, but it is naturally found in foods like prunes, raisins, nuts, beans, avocados, and some fruits.
Silicon or Silica
Silicon, often listed as silica, is found in foods such as whole grains, bananas, green beans, leafy greens, and some mineral waters. It is often discussed in relation to connective tissue, hair, skin, nails, and bone health, though more research is needed.
Food First, Supplements When Needed
The best way to support mineral intake is to build meals around a variety of whole foods. Still, some people may benefit from a mineral supplement depending on diet quality, life stage, health needs, lab results, or provider guidance.
Iron is one mineral to think about carefully. Some people need more iron, while others may not need supplemental iron at all. Men, postmenopausal women, and anyone who has been told to avoid iron should be especially mindful of choosing the right formula.
Mineral Support Without Iron
Bio-M for Men is a mineral-only formula without iron. It may be a good fit for men, postmenopausal women, or anyone looking for a mineral formula without added iron.
Mineral Support With Iron
Bio-M for Women is a mineral-only formula with iron. It is designed for women who want mineral support that includes iron as part of their daily routine.
As with any supplement, follow product directions and talk with a healthcare provider if you are pregnant, nursing, taking medication, managing a health condition, or unsure whether you need supplemental minerals.
The Bottom Line
Minerals may be needed in small amounts, but their impact is anything but small. They support bones, muscles, nerves, metabolism, oxygen transport, thyroid function, immune health, and antioxidant defenses.
Start with food first, then use supplements thoughtfully when extra support makes sense for your needs.
