Great Salt Lake Trace Minerals.
Great Salt Lake brine contains a naturally occurring spectrum of dissolved minerals. MRI concentrates that mineral-rich brine through its manufacturing process, and ERYTH sources the resulting concentrate for its formulas — 70+ ionic trace minerals, naturally low sodium, untouched by synthetic processing.

— Why this water
One source.
Seventy-two minerals.
A trace mineral ritual is about adding a broader spectrum of naturally occurring minerals to the water you drink. ERYTH is built around the full elemental fingerprint of the Great Basin watershed — concentrated, ionic, and ready to mix into your daily hydration.
Great Salt Lake brine contains a naturally occurring spectrum of dissolved minerals. MRI concentrates that mineral-rich brine through its manufacturing process, and ERYTH sources the resulting concentrate for its formulas. This is what characterizes Great Salt Lake trace minerals: the full spectrum comes from a single source, not a reconstruction.

01 — Where it begins
A relic of the Pleistocene.
The Great Salt Lake is the surviving fragment of Lake Bonneville — the freshwater inland sea that once covered most of the Great Basin during the last ice age. As the climate warmed, the water receded, leaving behind a single, hyper-concentrated body of brine.
Geological filtration through the surrounding Wasatch and Uinta mountains has deposited every soluble mineral the watershed can give into a single inland sea. Great Salt Lake brine contains a naturally occurring spectrum of dissolved minerals that MRI concentrates through its manufacturing process.
The result is a naturally occurring mineral spectrum. Magnesium and potassium dominate. Sodium chloride sits secondary. Dozens of ultra-trace minerals — boron, lithium, vanadium, strontium — round out the spectrum.
This is the water we begin with. Everything else is reduction, never addition.
02 — Why it matters
Ionic. Whole-spectrum. Naturally dissolved.
ERYTH carries every mineral in its natural ionic form — dissolved and ready to mix into the water you drink. No chelates, no oxides, no reconstructions. The full elemental fingerprint of the lake, concentrated and made drinkable.
The Great Salt Lake brine naturally carries magnesium, sodium, potassium, and 70+ trace elements in the ratios present in the source water. Potassium runs naturally low in the lake, so a measured amount is blended back in to balance the profile — every other mineral comes straight from the brine.
03 — From the lake to the bottle
Sun. Time. Patience.
The trace minerals in every ERYTH bottle are solar-harvested in Utah by our long-standing mineral partner — a family-run operation that has been concentrating Great Salt Lake brine for decades. Here is their process, end to end.
Pump from the lake
Crude brine is drawn from regulated zones of Utah's Great Salt Lake and pumped into shallow solar evaporation ponds along the shoreline.
Solar concentrate
A 100% natural solar process driven by Utah's high-altitude sun reduces the brine over months — up to roughly two years for the most concentrated magnesium blends. Sodium chloride precipitates out first, so magnesium, potassium and 70+ trace elements concentrate further.
Tanker & temper
The mineral-dense concentrate is transported by tanker truck to the bottling facility and tempered in large stainless holding tanks before processing.
Lab verify
Every batch is analyzed for mineral content, physical properties and microbial load, plus independent heavy-metal testing (arsenic, lead, mercury, cadmium) against California Prop 65 limits.
Filter & bottle
MRI filters the concentrate on an automated liquid fill line into apothecary-grade cobalt glass to shield the minerals from light and oxidation. From ancient lake to dropper — untouched by plastic, heat or synthetic processing.

— Stewardship
Harvested with the lake in mind.
The Great Salt Lake is a fragile ecosystem and a critical migratory bird habitat. We work exclusively with Utah operators who use passive solar evaporation in shoreline ponds, draw from regulated brine zones, and tanker the finished concentrate to a single bottling facility — no offshore processing, no industrial heat, no synthetic additions.
Supplier batch documentation includes heavy-metal, microbial, and quality testing through MRI and its qualified testing partners. Transparency is non-negotiable — available documentation is shared with every order on request.

Questions about the source.
ERYTH's trace mineral concentrate is sourced from a single ancient water body — the Great Salt Lake in Utah. The lake is what remains of Pleistocene-era Lake Bonneville, and its brine holds more than 70 ionic trace minerals concentrated from the surrounding Wasatch and Uinta watershed. The mineral-rich brine is concentrated through MRI's manufacturing process, and ERYTH sources the resulting concentrate for its formulas — no blends, no isolates, no reconstructions.
Great Salt Lake brine contains a naturally occurring spectrum of dissolved minerals. MRI concentrates that mineral-rich brine through its manufacturing process, and ERYTH sources the resulting concentrate for its formulas.
ERYTH carries 70+ ionic trace minerals — including magnesium, potassium, chloride, zinc, selenium, chromium, iodine, manganese, molybdenum, boron, lithium, vanadium and strontium — alongside dozens of ultra-trace elements present in the original brine.
Solar evaporation takes time, and the concentration level depends on how long the brine sits in the pond. Lighter blends concentrate over a season of Utah sun; the most premium magnesium-dominant blends take roughly two years for nature to perfect. The longer the residence time, the more sodium chloride precipitates out and the more concentrated the remaining trace minerals become.

Sodium chloride crystallizes and precipitates out of the brine first during solar evaporation. As that salt drops out, the magnesium, potassium and trace elements left in solution concentrate further. What ships in the bottle is a deeply concentrated mineral brine that is naturally low in sodium and exceptionally high in magnesium and trace elements — the opposite ratio of most sea-derived products.
Powdered electrolytes typically contain three or four lab-synthesized salts (sodium chloride, potassium chloride, magnesium citrate). Solar-harvested ionic minerals from the Great Salt Lake deliver the full mineral spectrum in a naturally dissolved ionic form — no binders, sweeteners or fillers required.
