Trace Mineral Drops: Electrolytes, Multi-Mineral Supplementation & What the Evidence Actually Shows
⚡ 60-Second Summary
Trace mineral drops are concentrated liquid supplements made by solar-evaporating saline water (primarily from the Great Salt Lake in Utah) to remove most table salt (sodium chloride), leaving a dense brine of magnesium, potassium, sulfate, chloride, boron, and over 70 trace elements. The leading brand is ConcenTrace by Trace Minerals Research. The product has a straightforward appeal: it provides a broad spectrum of minerals that are individually essential and which many Western diets underdeliver.
Important limitation: No independent randomized controlled trial has tested the ConcenTrace blend (or any similar proprietary trace mineral concentrate) for a clinical health outcome. Evidence is extrapolated from the individual minerals, each of which has its own evidence base. The "synergistic blend" rationale is unproven.
Practical advice: Trace mineral drops can be a reasonable low-cost way to add magnesium and trace elements to a diet. But for specific deficiencies — especially magnesium — targeted single-mineral supplements (bisglycinate, malate, citrate) provide more precise elemental dosing. Always check for third-party heavy-metal testing before purchasing.
What are trace mineral drops?
Trace mineral drops are a category of liquid dietary supplement produced by concentrating naturally occurring mineral-rich water. The most common source is the Great Salt Lake in Utah, one of the saltiest bodies of water in the Western Hemisphere, which naturally contains high concentrations of magnesium, potassium, sulfate, chloride, boron, and more than 70 trace elements.
The production process is largely a passive solar evaporation: brine from the lake is pumped into evaporation ponds, where sun and wind concentrate the minerals over months. As sodium chloride (table salt) crystallizes out at lower concentrations, it is removed, leaving a more complex mineral concentrate. The resulting liquid is typically diluted, tested, and bottled as a supplement. The leading brand — ConcenTrace, produced by Trace Minerals Research in Utah — claims to remove over 99% of the original sodium through this process.
Similar products exist from other sources (Dead Sea mineral concentrates, deep-ocean mineral water concentrates from Japan and Taiwan). The mineral profile varies by source and processing, but all share the core principle of providing a broad-spectrum ionic mineral blend in liquid form.
What do trace mineral drops contain?
Per a typical 40-drop (~2 mL) serving of ConcenTrace, the major mineral contributions are approximately:
- Magnesium: 250–350 mg (as magnesium chloride)
- Chloride: 650–700 mg
- Sodium: 5–10 mg (after sodium chloride removal)
- Potassium: 3–5 mg
- Sulfate: 35–40 mg
- Lithium: trace amounts (~0.2 mg)
- Boron: trace amounts (~0.3 mg)
- And 70+ additional trace elements in microgram to nanogram quantities (including zinc, manganese, chromium, selenium, molybdenum, iodine, vanadium, and others)
Important caveat: exact mineral content varies by batch, season, and lake salinity levels — the Great Salt Lake has experienced significant salinity fluctuations due to drought and water diversion. Third-party batch testing is essential for knowing what you are actually consuming. Reputable brands publish certificates of analysis (COAs) on their websites.
What the evidence actually supports
Individual minerals in the blend — strong evidence for each
The component minerals in trace mineral drops are each individually essential nutrients with robust evidence bases:
- Magnesium (the predominant mineral): supports 300+ enzymatic reactions, blood pressure, sleep, muscle function, and glycemic control. See our magnesium bisglycinate page for the clinical evidence summary.
- Sulfate: a sulfur form involved in detoxification pathways and connective tissue (heparan sulfate, chondroitin sulfate).
- Chloride: an essential electrolyte for fluid balance, gastric acid production (as HCl), and nerve/muscle function.
- Trace elements (zinc, manganese, chromium, selenium): each is an essential cofactor for specific enzymes and metabolic pathways. Deficiency of any is associated with well-characterized clinical problems.
- Boron: a nutritionally beneficial ultra-trace element supporting bone and hormone metabolism. See our boron page for more.
The blend as a whole — no independent clinical trial evidence
No randomized controlled trial has tested ConcenTrace or an equivalent proprietary trace mineral concentrate for a clinical outcome (blood pressure, bone density, athletic performance, fatigue, etc.) against placebo. The supplement market's claim that these blends provide "complete mineral nutrition" or "superior absorption" compared to single-mineral supplements is not supported by comparative clinical data. The ionic form of minerals (freely dissociated in solution) is well absorbed, but this is equally true of many single-mineral supplements in chelated or soluble salt form.
Key limitations of the blend-evidence approach
- No dose precision: Because trace mineral drops contain dozens of minerals at concentrations that vary by batch and lake conditions, it is impossible to reliably dose specific minerals to a target level. If you need to address magnesium deficiency at 300 mg elemental/day, a bisglycinate or malate supplement gives you precision; trace drops do not.
- No RCT for the blend: Individual mineral evidence cannot be aggregated to prove the combined product works. This is a common category of reasoning error in supplement marketing.
- Heavy metal contamination risk: Great Salt Lake sediments contain naturally occurring arsenic, mercury, and other heavy metals. Quality manufacturers test for these; choose brands that publish independent third-party COAs.
- Declining lake levels: The Great Salt Lake has shrunk dramatically due to drought and water diversion, concentrating pollutants and altering the mineral balance of the brine over time. This is an evolving product quality consideration.
Trace mineral drop products compared
| Product / Source | Primary minerals | Third-party tested? | Notes |
|---|---|---|---|
| ConcenTrace (Trace Minerals Research) | Mg, Cl, SO4, 70+ trace elements | Yes (publishes COAs) | Market leader; Great Salt Lake source; GRAS status; sodium removed >99%. |
| Dead Sea mineral concentrate | Mg, K, Br, and trace elements | Varies by brand | Higher bromide content; useful for topical but less common orally. |
| Deep ocean mineral water (Japan/Taiwan) | Mg, trace elements | Varies by brand | Lower heavy-metal risk from deep ocean vs. saline lake; typically more expensive. |
| Sea salt (unrefined) | Na, Cl, small Mg, trace elements | Not a supplement | Contains trace minerals but sodium content far exceeds the mineral benefit. Not a substitute for trace mineral drops. |
How much should you take?
Product serving sizes vary, but the typical recommendation for ConcenTrace is:
- Starting dose: 10 drops per day, diluted in 8 oz of water or juice. Gradual introduction reduces the likelihood of GI discomfort from the concentrated mineral brine.
- Maintenance dose: 40 drops per day (approximately 2 mL), taken in divided doses with water or food.
- Timing: With meals to reduce GI discomfort. Avoid taking undiluted directly from the bottle — the concentrated mineral taste is very strong and can irritate oral tissues.
- Caveat on magnesium dosing: A 40-drop serving of ConcenTrace provides approximately 250–350 mg of magnesium. This is clinically relevant and may cause loose stools in some users, similar to magnesium chloride or magnesium oxide at equivalent doses. Start low and titrate up.
Always follow the specific product label. Do not exceed the manufacturer's recommended dose without reviewing the complete mineral panel for that batch.
Safety, side effects, and sodium concerns
Common side effects
- GI upset, loose stools, or diarrhea — particularly at higher magnesium doses. Start with the lower dose (10 drops/day) and increase gradually over 1–2 weeks.
- Bitter, metallic taste — dilute in juice or flavored beverages if the taste is bothersome with water.
- Nausea if taken undiluted or on an empty stomach
Sodium content
Although ConcenTrace claims >99% sodium removal, the remaining sodium in the concentrate is not zero. At 40 drops/day, a small but non-trivial amount of sodium is delivered. Individuals on strict sodium-restricted diets (cardiovascular disease, hypertension, kidney disease) should check the batch-specific sodium content on the COA or Supplement Facts panel. Most adults on unrestricted diets will not notice any meaningful impact from this sodium level.
Kidney disease
Individuals with reduced kidney function have impaired ability to excrete excess minerals including magnesium, potassium, and trace elements. The multi-mineral nature of trace drops makes them particularly unsuitable for individuals with CKD without nephrology supervision — there is no way to independently titrate any one mineral, and accumulation of multiple elements simultaneously is possible.
Heavy metal risk
Select brands with independent third-party testing for arsenic, lead, mercury, and cadmium. The Great Salt Lake naturally concentrates some of these from decades of upstream agricultural and industrial runoff. Reputable brands (ConcenTrace) test for heavy metals and publish results; always verify before purchasing.
Who might benefit — and who shouldn't bother
| Most likely to benefit | Unlikely to benefit / better options exist |
|---|---|
| Adults seeking a broad-spectrum multi-mineral supplement at low cost | Individuals with specific known mineral deficiencies — targeted single-mineral supplements offer better dose precision |
| Active adults and athletes replacing electrolytes and trace elements lost in sweat | People with kidney disease — too many minerals to monitor simultaneously without medical supervision |
| People who eat a very processed diet with limited vegetable and mineral intake | Those on strict sodium-restricted diets who cannot tolerate any incremental sodium |
| Users who want to add minerals to otherwise mineral-poor water sources (reverse osmosis water) | Anyone expecting the blend to provide proven outcomes beyond what individual minerals already demonstrate |
Frequently asked questions
What are trace mineral drops?
Concentrated liquid mineral supplements produced by evaporating saline water (primarily Great Salt Lake brine), removing most sodium chloride, and concentrating the remaining ionic minerals. The leading brand is ConcenTrace. They contain magnesium, chloride, sulfate, and over 70 trace elements. They are a broad-spectrum mineral supplement, not a targeted single-nutrient product.
Do trace mineral drops work?
The individual minerals they contain are essential and well-supported by science. The specific blend, however, has not been tested in an independent clinical trial. Evidence is extrapolated from individual minerals, not from the product as formulated. For targeted outcomes (e.g., addressing magnesium deficiency), single-mineral supplements with precise elemental dosing are more reliable.
Is there heavy metal contamination in trace mineral drops?
This is a legitimate concern, particularly for Great Salt Lake-derived products, given historical upstream agricultural and industrial pollution. Reputable manufacturers (ConcenTrace) test for arsenic, lead, mercury, and cadmium and publish COAs. Always verify the brand publishes independent third-party heavy metal testing before purchasing.
Can trace mineral drops help with electrolyte balance?
Yes, in a general sense. They contain magnesium, chloride, potassium, and sodium in ionic form — all key electrolytes. For athletes or people sweating heavily, adding trace drops to water can provide electrolyte replacement. However, the magnesium content (250–350 mg at a full 40-drop serving) may cause loose stools at full doses. For electrolyte replacement specifically, sports-targeted formulations with calibrated sodium-potassium-magnesium ratios may be more practical.
Are trace mineral drops safe for children?
Use with caution and only with pediatrician guidance. The appropriate mineral dose for children differs from adults, and the multi-mineral nature of the product makes precise pediatric dosing difficult. The high magnesium content per serving (relative to a child's body weight) can cause diarrhea. Dedicated pediatric multi-mineral formulations with age-appropriate doses are preferable.
