What Are Trace Minerals?
The seventy-plus elements your cells need in microscopic amounts — and why almost no modern diet delivers enough.
Trace minerals are essential nutrients your body needs in tiny amounts — typically less than 100 milligrams per day. They include zinc, iron, copper, selenium, chromium, iodine, manganese, and dozens of ultra-trace elements like boron, lithium, and strontium. They show up in nearly every biological process: immune defense, thyroid hormones, energy metabolism, antioxidant protection, even how well you sleep.
01 — The two families
Macro minerals vs. trace minerals.
Macro Minerals
Needed in grams
- CaCalciumBone, nerve signaling
- MgMagnesium300+ enzyme reactions
- NaSodiumHydration, fluid balance
- KPotassiumHeart, muscle contraction
- ClChlorideStomach acid, fluid balance
Trace Minerals
Needed in micrograms
- ZnZincImmunity, skin, hormones
- FeIronOxygen transport
- CuCopperEnergy, connective tissue
- SeSeleniumAntioxidant defense
- CrChromiumGlucose metabolism
- IIodineThyroid function
- MnManganeseBone, enzyme cofactor
- MoMolybdenumDetoxification enzymes
…plus 60+ ultra-trace minerals (boron, lithium, vanadium, strontium, and more) found in ERYTH's whole-spectrum source.
02 — Why they matter
Small amounts. Massive shift.
Trace minerals are cofactors — they unlock the enzymes that run your body. Without zinc, you can't make stomach acid. Without selenium, your antioxidant defense stalls. Without iodine, thyroid hormones can't form.
Modern soils have been farmed and refined for a century, and the minerals that used to land in your produce are largely gone. The result: even a high-quality diet often delivers a fraction of what your great-grandparents got from the same plate.
03 — Signs you're low
What mineral depletion feels like.
Persistent fatigue
Even after sleep, energy never quite resets.
Muscle cramps
Especially calves at night, or hands during work.
Brain fog
Slow word recall, dropped focus mid-sentence.
Brittle nails & hair
Slow growth, splitting, dull texture.
Disrupted sleep
Waking at 3am, restless legs, racing mind.
Slow recovery
Workouts hit harder; soreness lingers.
04 — Forms of minerals
Ionic, chelated, colloidal —
what's the difference?
Ionic
Dissolved into their natural electrical charge. The form found in spring water, sea brine, and your own blood plasma. Absorbed within minutes — no conversion required. ERYTH is ionic.
Chelated
Lab-bound to amino acids (e.g. magnesium glycinate). Decent absorption but slower; some are well-tolerated, others poorly absorbed depending on the chelate.
Colloidal
Suspended particles, not dissolved. Often poorly absorbed; quality varies wildly between brands.
Oxide
The cheapest form — magnesium oxide, zinc oxide. Found in most drugstore multivitamins. Absorption rates often below 10%.
05 — FAQ
Common questions about
trace minerals.
Trace minerals are essential elements your body needs in tiny amounts — measured in micrograms or milligrams. They include zinc, iron, copper, selenium, chromium, iodine, manganese, and dozens more. Despite the small quantity, they power hundreds of enzyme reactions and cellular processes.
Electrolytes are a small group of macro minerals (sodium, potassium, magnesium, calcium, chloride) that carry electrical charge in fluids. Trace minerals are a much wider category — 70+ elements your body needs in smaller doses for everything from immunity to thyroid function.
Common signs include persistent fatigue, muscle cramps, brain fog, brittle nails, slow recovery, and disrupted sleep. Modern soils have been depleted for decades, so even a clean diet often falls short on minerals like selenium, magnesium, and iodine.
No. Most multivitamins contain isolated, lab-synthesized minerals in chelated or oxide forms. Whole-spectrum ionic trace minerals come from natural water sources and arrive in the form your cells already recognize — no conversion needed.
Sea vegetables, mineral-rich spring water, organ meats, and unrefined sea salt are the deepest food sources. For most people, a daily ionic mineral concentrate (like ERYTH) is the fastest, most absorbable way to fill the gap.
