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: cassava powder. Cassava is a starchy root vegetable that's eaten as food in many parts of the world.

There are no other inactive ingredients listed.

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 Cassava product and its label doesn't state a use — see Cassava'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.

The evidence for cassava powder as a supplement isn't established in the data we hold. We have no reliable evidence to rate it for diabetes, diarrhea-related dehydration, or other uses.

While cassava is eaten as a food, the effectiveness of cassava supplements for medical purposes hasn't been studied well enough to know whether they work.

The evidence, ingredient by ingredient Cassava

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.

Properly cooked cassava is a common food, and that's important because raw or poorly processed cassava can cause cyanide poisoning. Cassava contains compounds called cyanogenic glycosides that turn into cyanide if not removed during cooking.

Symptoms of cyanide poisoning include nausea, vomiting, stomach pain, diarrhea, dizziness, weakness, and headache. In rare cases, consuming unprocessed cassava has been linked to nervous system damage, including paralysis.

Cassava intake has also been associated with an increased risk of an underactive thyroid (hypothyroidism). Rarely, people allergic to latex may have an allergic reaction to cassava, which can include skin reactions, swelling, breathing trouble, cough, or in severe cases, anaphylaxis.

Because cassava supplements aren't well studied and carry cyanide concerns, concentrated supplements are best avoided.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Cassava.
  • The most serious interaction on file is rated Moderate.
  • For scale: 16 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.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Cooked cassava as a food is fine, but taking it as a concentrated supplement isn't well studied and carries real safety concerns—mainly cyanide poisoning and thyroid effects. If you take thyroid medication, check with us or your doctor before trying this product.

For most people, there are safer, better-studied options.

Thyroid Hormone

Evidence from human and animal research suggests that cassava root has marked antithyroid effects, particularly if poorly processed or if consumed as part of a protein-deficient diet. Also, clinical research shows that consuming boiled cassava leaves 200 grams twice daily for 9 days significantly reduces levels of the thyroid hormones triiodothyronine and thyroxine. Theoretically, cassava may alter thyroid function, reduce thyroid hormone levels, and interfere with thyroid hormone-replacement therapy.

Cassava (Tapioca) Powder by TerraVita Premium Collection: Common Questions

Does Cassava (Tapioca) Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Cassava (Tapioca) Powder has a known interaction with 16 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cassava (Tapioca) Powder 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.
Is cassava powder safe to take if I have a thyroid condition?
If you take thyroid medication, you should be cautious. Cassava has been shown to lower thyroid hormone levels, which could interfere with your treatment. Talk with your pharmacist or doctor before trying this product.
What happens if cassava isn't processed properly?
Raw or poorly processed cassava can contain cyanide-forming compounds that cause nausea, vomiting, stomach pain, diarrhea, dizziness, weakness, and headache. In more serious cases, unprocessed cassava has been linked to nerve damage and paralysis. That's why concentrated supplements are best avoided.
Can I be allergic to cassava?
Allergic reactions are rare, but they can happen—especially in people who are already allergic to latex. Symptoms can range from skin reactions and swelling to breathing problems or, rarely, severe anaphylaxis.
Does cassava powder work for diabetes or diarrhea?
We don't have reliable evidence that cassava powder works for either of those purposes. While cassava is eaten as a food, the effectiveness of cassava supplements hasn't been studied well enough to know.
Is it safe to take cassava powder while pregnant or breastfeeding?
The safety data suggests cassava may not be safe during pregnancy or while breastfeeding. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or nursing.
