HelloPharmacist Scorecard of Clay, Green Powder by TerraVita Premium Collection

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.

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: green clay powder. Green clay is a naturally occurring mineral that has been studied for its potential effects on digestive health, particularly for certain types of diarrhea.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Clay's overall clinical evidence instead.

Moderate

Some clinical evidence supports Clay for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Rotaviral diarrhea — rated "Possibly Effective" (Natural Medicines).

The evidence for green clay is mixed. It's rated possibly effective for rotaviral diarrhea (a viral infection that causes watery stools).

For other uses—including chemotherapy-induced diarrhea and irritable bowel syndrome (IBS)—there isn't enough reliable evidence to rate how well it works.

The evidence, ingredient by ingredient Clay

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.

Short-term oral use of green clay is generally well tolerated, though some people experience mild constipation, vomiting, or diarrhea. The main safety concern is that clay can be contaminated with heavy metals, especially with long-term or habitual use.

Habitual clay ingestion has been linked to iron deficiency anemia, low potassium (which can cause muscle weakness), heart problems including abnormal rhythms and enlarged heart muscle, and in some cases lead poisoning. The safety data advises against using clay during pregnancy due to heavy-metal and nutrient-absorption concerns.

There isn't enough information to know whether it's safe while breastfeeding—talk with your doctor or pharmacist for personalized advice.

Side effects, ingredient by ingredient Clay

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Clay.
  • The most serious interaction on file is rated Moderate.
  • For scale: 3 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your pharmacist if you take cimetidine (Tagamet) or quinine—both are Moderate interactions. Green clay can reduce how well your body absorbs these medications.

No other medication interactions are documented for the ingredients we could check, but that doesn't mean none exist.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

If you have rotaviral diarrhea, green clay may be worth considering. If you take cimetidine or quinine, check with us first—clay can make them less effective.

For long-term use, be aware of the heavy-metal contamination risk. Talk with your pharmacist before starting, especially if you're pregnant, breastfeeding, or take any regular medications.
