What is this page for?

First and foremost: checking Cobalt Concentrate against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.

Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Cobalt Concentrate by Complete H2O Minerals

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: cobalt, supplied as cobalt chloride in a liquid form with purified water and benzoic acid as inactive ingredients.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Cobalt product and its label doesn't state a use — see Cobalt's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

We hold no effectiveness data for cobalt supplements in our records. The product facts don't establish what this supplement is intended to support.

The evidence, ingredient by ingredient Cobalt

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Inorganic cobalt supplements like this one have no proven benefit and carry real risks — the safety data advises against their use. Cobalt taken by mouth long-term or in high doses may cause cardiomyopathy (heart muscle weakness), hearing loss, and vision loss.

Avoid this product during pregnancy and while breastfeeding due to toxicity concerns and lack of safety data; rely on vitamin B12 instead if you need cobalt. When taken orally in small amounts for up to 90 days, cobalt seems to be well tolerated, but the long-term safety profile is concerning.

Side effects, ingredient by ingredient Cobalt

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredient we could check. However, because cobalt itself carries serious toxicity risks, confirm with your doctor or pharmacist that this product is right for you before you start it, regardless of what other medications you take.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

The safety data advises against inorganic cobalt supplements because they offer no proven benefit and carry risk of serious harm — especially to the heart, ears, and eyes with long-term or high-dose use. This product is not recommended during pregnancy or breastfeeding.

Talk with your doctor or pharmacist before taking this product, especially if you're considering it long-term or in addition to other supplements.

Cobalt Concentrate by Complete H2O Minerals: Common Questions

Does Cobalt Concentrate by Complete H2O Minerals interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Cobalt Concentrate. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Cobalt Concentrate contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is cobalt supposed to do?
We hold no effectiveness data for cobalt supplements in our records, so we can't tell you what benefit this product is meant to provide. The safety notes make clear that inorganic cobalt supplements have no proven benefit.
Is cobalt safe to take long-term?
No. When cobalt is taken by mouth in small amounts for up to 90 days, it seems to be well tolerated — but long-term use or high doses may cause cardiomyopathy, hearing loss, and vision loss. The safety data advises against inorganic cobalt supplements because they offer no proven benefit and carry these serious risks.
Can I take this while pregnant or breastfeeding?
No. Avoid cobalt supplements during pregnancy because of toxicity concerns and lack of safety data. While breastfeeding, avoid cobalt supplements and rely on vitamin B12 instead if you need cobalt.
What are the side effects?
In small amounts for short periods, cobalt is generally well tolerated. Long-term or high-dose use may cause cardiomyopathy, hearing loss, and vision loss. You're at greater risk if you eat a low-protein diet, are deficient in thiamine (vitamin B1), or have an underactive thyroid.
Does this product have any fillers?
Yes — the inactive ingredients are purified water, cobalt chloride (which supplies the cobalt), and benzoic acid.
