HelloPharmacist Scorecard of Cassava Supplement by Forever Blessed
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
This single-ingredient supplement contains cassava. In some parts of the world, cassava root is eaten as a food, but this product delivers a concentrated form in capsule form, which differs from how it's traditionally consumed.
Does it work?
Couldn't assess
The evidence for cassava in treating diabetes or diarrhea-related dehydration is insufficient to rate its effectiveness. We don't hold reliable data showing it works for these uses.
How safe is it?
Well-documented data
Properly cooked cassava as a food is generally eaten, but raw or poorly processed cassava can cause cyanide poisoning. Symptoms include nausea, vomiting, stomach pain, diarrhea, dizziness, weakness, and headache.
In rare cases, cassava has triggered allergic reactions (including hives, swelling, and difficulty breathing) in people who also have a latex allergy. The safety data advises against use in pregnancy and while breastfeeding, since there isn't enough information to know it's safe for the developing baby or nursing infant.
Meds to double-check
Moderate interaction found
If you take thyroid hormone medication (such as levothyroxine), check with your pharmacist before using this product—cassava can reduce how well your thyroid medication works.
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.
This supplement carries a Moderate interaction with thyroid medications and unresolved safety concerns about cyanide content in concentrated supplements. If you take thyroid hormone, talk to your pharmacist before starting.
If you're pregnant, planning pregnancy, or breastfeeding, the safety data suggests avoiding it—discuss with your doctor or pharmacist for personalized advice.

Cassava monograph & interactionsCassava Supplement by Forever Blessed Drug Interactions
HelloPharmacist Interaction Report
Forever Blessed Cassava Supplement interacts with thyroid hormones (levothyroxine, liothyronine, desiccated thyroid, and others), a Moderate-severity concern.
Research in humans and animals shows cassava can suppress thyroid hormone production, especially if the cassava isn't processed well or if someone's diet is low in protein. Clinical trials found that boiled cassava leaves consumed in large amounts significantly lowered levels of active thyroid hormones.
Read the full breakdown — every affected drug type, severity by severity
Although cassava is eaten as a food in many parts of the world, this supplement raises additional safety flags beyond interactions. Cassava contains compounds that can break down into cyanide if not properly processed during manufacturing, potentially causing nausea, vomiting, stomach pain, dizziness, weakness, and headache.
Concentrated supplements haven't been well studied, and the safety data suggests they're best avoided.

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.
