Liquid concentrates of mixed minerals, typically derived from inland sea water, humic shale deposits or salt lake brine, marketed as supplying dozens of trace elements in an absorbable form.
This category is defined by what its labels do not tell you. Products commonly claim 70 or more trace minerals, most of which have no established human requirement and several of which — aluminium, lithium, arsenic, boron, nickel — are present because they are simply what was in the source material. There are essentially no clinical trials. Mineral content varies between batches with the geology of the deposit, quantitative amounts are frequently absent from the label, and the concept behind the marketing — that modern soils are depleted and food no longer supplies trace elements — is not supported by food composition data for the minerals that actually matter. Where a genuine deficiency exists, a defined single-nutrient supplement addresses it measurably; a shale extract does not.
Sold as
Liquid drops, Concentrate for dilution, Capsule, Component of "electrolyte" and greens products
Also known as
Ionic trace minerals, Colloidal minerals, Fulvic mineral drops, Sea mineral concentrate
Regulation: Sold as a dietary supplement with no pre-market efficacy or safety review and no requirement to quantify most of the elements claimed. The FTC has taken action against colloidal mineral marketers over unsupported disease claims. Individual upper limits still apply to whatever the product actually contains.
What the research used
The amounts, forms and durations published trials of Colloidal and ionic trace minerals actually administered.
These are the amounts published trials administered — not a recommendation, and not a dose to copy. Trial participants were screened, supervised and given a characterised preparation. What is in a retail bottle is frequently not what was studied, and the amount that suits one person is not general advice.

Not enough
Drops in water, daily
No dependable dose figure can be given: most products state the mineral list rather than quantities, and content varies with the source deposit and batch. Treating the delivered amount of any individual mineral as unknown is the honest position.
This is general information about food, not medical advice. It cannot diagnose, treat or replace guidance from a clinician who knows your history.
When it was taken
Each window says whether a trial compared it against an alternative, or whether it is convention and pharmacology. Most timing advice is the second kind.
None of the timings below were directly compared in a trial. They reflect how the research happened to dose, or what the pharmacology implies — which is not the same as a timing being better.
🕐Any time
Not enough
No timing has been studied for these products, and no trial of any kind has been published on them.
Timing was not directly compared. This reflects convention or how the compound behaves in the body, not a trial showing this window works better.
The evidence in depth
Best supported: Not enough
What each association actually rests on, and the papers behind it. A rating describes the state of the research, not how promising the supplement sounds. How we rate evidence.
There is no clinical trial evidence behind colloidal or ionic trace mineral products for energy or any other outcome. The rationale — widespread trace element depletion in food — is asserted rather than demonstrated for the minerals with established requirements.
Not enough evidence. Not enough human research to say anything useful yet.
No source is attached to this association yet, so it is rated not enough evidenceby default. It is listed because people commonly ask about it — not because there is evidence for it.
Trace mineral drops are commonly added to sports drinks and electrolyte mixes. No trial has tested them for hydration, cramp or recovery outcomes, and the mineral quantities they supply are usually far too small to matter for electrolyte balance.
Not enough evidence. Not enough human research to say anything useful yet.
No source is attached to this association yet, so it is rated not enough evidenceby default. It is listed because people commonly ask about it — not because there is evidence for it.
Things to know
Interactions, contraindications and dose limits, most serious first. Concentrated extracts interact with medication in ways the whole plant does not, so this section carries more weight here than it does on a food page.
Worth knowing
Undisclosed heavy metals and aluminium
Humic shale and brine sources naturally contain aluminium, arsenic, lead and cadmium alongside the desirable elements, and analyses of colloidal mineral products have found substantial aluminium content. Since quantities are rarely stated, buyers cannot assess exposure — which matters most for children, in pregnancy and in kidney impairment.
Too much
Upper limits still apply to what is inside
Whatever a product actually contains counts toward the upper limits for selenium, copper, manganese, iodine and the rest. A "70 minerals" claim gives no way to check this, and stacking with a multivitamin compounds the problem.
Worth knowing
The depleted-soil premise is not established
The marketing rests on the claim that modern food no longer supplies trace minerals. Food composition data do not support that for the minerals with established requirements, and where deficiencies do occur — iodine, iron, zinc — a defined supplement corrects them measurably.
Worth knowing
Contains lithium and other pharmacologically active elements
Some products contain measurable lithium, boron and vanadium, all of which have their own dose considerations and, in lithium's case, drug interactions. None of this is usually quantified on the label.
