HelloPharmacist Scorecard of Lectin Protect by Supreme Nutrition Products

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 13, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Lectin Protect” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Lectin Protect contains three active ingredients. Fucus vesiculosus (bladderwrack, a type of seaweed) is the ingredient with documented interactions; it's included for its iodine content and other compounds.

Larix occidentalis (western larch) and Abelmoschus esculentus (okra) round out the blend. The capsules themselves are vegetable cellulose, an inert container material.

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 Fucus Vesiculosus product and its label doesn't state a use — see Fucus Vesiculosus'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 Lectin Protect's effectiveness is not established in the data we hold. Fucus vesiculosus has been studied for aging skin, heart disease, constipation, diarrhea, and indigestion, but all of these uses have insufficient reliable evidence to rate at this time.

If you're considering this product for a specific health goal, talk with your doctor or pharmacist about whether the evidence supports it.

The evidence, ingredient by ingredient Fucus Vesiculosus

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.

When taken by mouth, Fucus vesiculosus raises significant safety concerns due to its variable and often high iodine content. The most common side effects are thyroid-related: goiter, low thyroid hormone (hypothyroidism), and overactive thyroid (hyperthyroidism).

Rarely, thyroid cancer has been reported. There's also a case report of a patient who developed an irregular heart rhythm after taking a weight-loss product containing Fucus vesiculosus, though it's unclear if Fucus vesiculosus alone was responsible.

During pregnancy, the high iodine and potential for heavy metal contamination make this product unsafe. During breastfeeding, iodine passes into breast milk and may affect your baby's thyroid function, so it should be avoided.

If you're pregnant, nursing, or planning to become pregnant, do not take this product without speaking with your doctor or pharmacist.

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 — Fucus Vesiculosus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 892 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 your medications against this product if you take lithium, antithyroid drugs, thyroid hormone replacement, or amiodarone (Cordarone)—all carry Moderate interaction risk with Fucus vesiculosus. Also double-check if you're on blood thinners (anticoagulants), antiplatelet drugs, or any medication metabolized by CYP2D6, CYP2C9, or CYP3A4 enzymes.

Your doctor or pharmacist can review your full medication list to ensure it's safe to combine with this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Lectin Protect carries moderate interaction risks, chiefly through Fucus vesiculosus and its effect on thyroid function and medications that regulate it. It's best suited only for people who don't take lithium, antithyroid drugs, thyroid hormone, or amiodarone—and who are not pregnant or breastfeeding.

Before you start, run your medications through the interaction checker on this page or talk it over with your doctor or pharmacist to confirm it's safe for you.

Each ingredient & the kinds of drugs it affects

For each ingredient in Lectin Protect with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Fucus Vesiculosus9 drug types · 891 drugs

Amiodarone (Cordarone)

Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Lithium

Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using thyroid hormone could alter the effects of thyroid hormone.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.

Likelihood Unlikely Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.

Lectin Protect by Supreme Nutrition Products: Common Questions

Does Lectin Protect by Supreme Nutrition Products interact with any medications?
Yes. Based on its ingredients, Lectin Protect has a known interaction with 891 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lectin Protect contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this if I'm pregnant or breastfeeding?
No. The product's high iodine content and potential for heavy metal accumulation make it unsafe during pregnancy. Iodine also passes into breast milk and may harm your baby's thyroid, so it should be avoided while nursing. Talk with your doctor or pharmacist about safer options.
What is Fucus vesiculosus, and why is it in this product?
Fucus vesiculosus is a type of seaweed also called bladderwrack. It's included in this product for its iodine content and other compounds, though evidence for its benefits is insufficient at this time.
What are the main side effects of this product?
The most common side effects are thyroid-related due to Fucus vesiculosus's high iodine content: goiter, underactive thyroid, and overactive thyroid. Rarely, thyroid cancer has been reported. There's also one case report of an irregular heart rhythm, though the exact cause wasn't clear.
Can I take this with my thyroid medication?
You shouldn't take this with thyroid hormone replacement, antithyroid drugs, or lithium without checking with your doctor or pharmacist first—Fucus vesiculosus's iodine content can interfere with how these drugs work and affect thyroid function.
Why does the product contain heavy metals?
The product itself may concentrate heavy metals because Fucus vesiculosus, being a seaweed, can absorb and store metals from seawater. This is why it carries a caution about variable iodine and heavy metal content.
What is Lectin Protect (the ingredient listed) and what does it do?
The 'Lectin Protect' listed as an ingredient is the brand's proprietary blend name—its actual active components are Fucus vesiculosus, Larix occidentalis, and Abelmoschus esculentus, which are listed separately.
