Azomite

MineralTrace mineral blend

What is it

Azomite is a brand name for a hydrated sodium calcium aluminosilicate (HSCAS) mineral deposit mined in Utah. It is widely used as a soil amendment and animal feed additive. Some supplement products market it as a trace mineral source for humans, though its primary application is agricultural.

Evidence for 2 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Plant and livestock nutrition (agricultural)

Good Evidence

Established trace mineral source for soil and livestock.

Human trace mineral supplementation

Mixed Evidence

No good human evidence supports use as a dietary supplement; aluminum content raises concern.

How it works

Azomite contains over 70 trace minerals, including silica, aluminum silicate, calcium, magnesium, potassium, and various rare-earth elements. In agriculture, it improves plant growth and animal health through trace mineral supplementation and aluminosilicate's adsorptive properties. As a human supplement, the bioavailability of most minerals is low, and aluminum content is a concern; the U.S. FDA has not approved Azomite as a human dietary supplement.

Dosage

No human dose is established. Marketing suggests 1/4 to 1 teaspoon per day; this is not based on clinical evidence.

When and how to take it

Not recommended for routine human use.

Azomite powder

Primarily a soil amendment and animal feed additive.

Low bioavailability for most minerals; aluminum content concerning.

Safety

Concerns include aluminum and other heavy metal content. Long-term aluminum exposure has been associated with neurological and bone effects. Silica dust is a respiratory hazard during handling but generally not an oral concern.

Who should be cautious

Avoid in pregnancy and breastfeeding. Avoid in people with kidney disease (impaired aluminum clearance). Children should not take Azomite. The product is more appropriate for agricultural and animal applications.

Interactions

Like other clay-type minerals, may bind medications and other supplements; separate by 1 to 2 hours.

Frequently asked questions

Is Azomite safe to eat?⌄

It is not FDA-approved as a human supplement. Aluminum and other heavy metal content raise concerns about long-term use.

Should I take it for trace minerals?⌄

Better alternatives exist. Trace mineral supplements designed for human use have better bioavailability and safety profiles.
