From our pharmacy team — supplement deep dive

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: Iceland Moss Whole Plant Extract, Dry. Iceland moss is a lichen (a type of organism that's part plant, part fungus) used traditionally to support respiratory and digestive health.

The liquid formulation also contains alcohol, water, and glycerin 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 Iceland Moss product and its label doesn't state a use — see Iceland Moss'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 don't hold effectiveness ratings for Iceland Moss in our data, so the evidence for what it does isn't established here. If you're considering it for a specific condition, your pharmacist or doctor can point you toward what's known about it from other sources.

The evidence, ingredient by ingredient Iceland Moss

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.

Iceland Moss is generally well tolerated for short-term use, though human evidence is limited and quality can vary between products. The main concerns are GI irritation — some people experience stomach upset — and potential lead contamination.

Iceland moss can absorb lead from soil, and while sensitization to the plant itself is rare, consuming it regularly as a primary food source over a long time could lead to lead buildup in your body. Because of insufficient safety data, it's best avoided during pregnancy and while breastfeeding unless your doctor has cleared it.

Iceland Moss by Herbal Terra: Common Questions

Does Iceland Moss by Herbal Terra interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Iceland Moss. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Iceland Moss 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.
Can I take Iceland Moss if I'm pregnant?
The safety data advises against it — there isn't enough information to know it's safe during pregnancy. Talk with your doctor or pharmacist about whether it's right for you.
Is it safe while breastfeeding?
Safety while breastfeeding isn't known, so it's best avoided unless your doctor has cleared it. Reach out to them before starting it.
What are the side effects?
Most people tolerate it well short-term. The main concern is GI irritation — some folks experience stomach upset. Iceland moss can also pick up lead from soil, which could build up in your body if you use it regularly over a long time.
Does it interact with my medications?
No interactions are documented in our data for Iceland Moss. You can double-check your specific medications using the search tool on this page if you'd like extra reassurance.
Why is the quality variable between products?
