HelloPharmacist Scorecard of Sea Kelp Enhanced by Dr. Berg
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
Low disclosure
This product has 4 active ingredients. Iodine is the one we have full data on — it's a mineral your thyroid needs, and the evidence shows it's effective for preventing radiation exposure damage and treating iodine deficiency.
The other three actives are Red Marine Algae, Klamath Blue-Green Algae, and Sea Kelp, all sourced from marine plants. The capsule also contains inactive ingredients including microcrystalline cellulose and magnesium stearate.
Does it work?
Strong evidence
Iodine in this product is Likely Effective for radiation exposure and iodine deficiency, and Possibly Effective for oral mucositis (mouth sores) and periodontitis (gum disease). We don't have effectiveness data on file for the other three ingredients — Red Marine Algae, Klamath Blue-Green Algae, and Sea Kelp.
How safe is it?
Well-documented data
Iodine is well tolerated in normal dietary amounts, but high doses carry a risk of thyroid problems — that's the main caution. In pregnancy, adequate iodine matters for the baby's development, but only take the amount your doctor recommends and steer clear of high-dose products.
The same goes for breastfeeding: some iodine passes into milk, so stick to medical guidance. Common side effects are rare but can include stomach upset, diarrhea, nausea, metallic taste, headache, and — with chronic high-dose use — acnelike skin lesions.
True iodine allergy is uncommon; what's often called an iodine allergy is usually a reaction to seafood protein or contrast dye instead.
Meds to double-check
Moderate interaction found
If you take lithium, antithyroid drugs (like methimazole or propylthiouracil), or amiodarone (Cordarone), check with your pharmacist before using this product — all three are Moderate interactions that affect thyroid function. We could not check interactions for the algae-based ingredients, so mention those to your pharmacist too.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This is mainly an iodine supplement, useful if you're deficient or need the radiation-protective effect. If you take lithium, an antithyroid drug like PTU or methimazole, or amiodarone, you need to check with your pharmacist first — your thyroid will need monitoring.
Anyone with a history of thyroid trouble should also chat with their doctor before starting.

Sea Kelp Enhanced by Dr. Berg Drug Interactions
HelloPharmacist Interaction Report
Sea Kelp Enhanced by Dr.
Berg contains iodine, which interacts with several medications, most notably lithium and antithyroid drugs — both Moderate severity. Iodine can add to lithium's effect of slowing thyroid function, and it may alter how antithyroid medications work, since high-dose iodine itself can shift thyroid function either way depending on your history.
Your doctor will want to monitor your thyroid if you're on either of these.
Read the full breakdown — every affected drug type, severity by severity
Amiodarone (Cordarone), a heart rhythm drug that's already high in iodine, is another Moderate concern — combining it with this product could push your iodine levels too high and damage thyroid function.
We could not check three other ingredients in this product: Red Marine Algae, Klamath Blue-Green Algae, and Sea Kelp itself — we hold no interaction data for them. Altogether, these interactions span 7 individual medications.

For each ingredient in Sea Kelp Enhanced with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Sea Kelp
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.
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.
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.
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.
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.
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.
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.
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.
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.
Iodine
Amiodarone (Cordarone)
Combining iodine with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with iodine might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.
Antithyroid Drugs
Iodine might alter the effects of antithyroid drugs.
Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking iodine while using antithyroid drugs could alter the effects of the antithyroid drugs.
Lithium
Combining iodine with lithium might have additive hypothyroid effects.
Lithium can inhibit thyroid function. Several case reports suggest that concomitant use of lithium and potassium iodide can reduce thyroid function in otherwise healthy adults. Monitor thyroid function.
