HelloPharmacist Scorecard of Ecklonia Cava Extract 53 mg by Swanson GreenFoods Formulas
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 product contains one active ingredient: Ecklonia cava 25:1 extract, a concentrated form of a brown seaweed. The extract is standardized to 53 mg per capsule.
The capsule itself is made from hypromellose, a plant-based cellulose material.
Does it work?
Moderate evidence
Ecklonia cava shows possibly effective evidence for helping with high cholesterol (hypercholesterolemia). For athletic performance, diabetes, and cancer, the evidence isn't established in the data we hold — there isn't enough reliable research to rate how well it works for those uses yet.
How safe is it?
Well-documented data
Long-term safety data for Ecklonia cava aren't well established, and seaweed products can carry high iodine levels, which is a concern if you take this product regularly over time. The safety data during pregnancy and breastfeeding aren't reliable — the safety data during breastfeeding specifically advises against use.
In clinical trials, a small number of people reported hair loss (alopecia), and single individuals reported nausea, indigestion (dyspepsia), and diarrhea.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, always confirm with your own doctor or pharmacist before starting any new supplement, especially if you take thyroid medication or have an iodine sensitivity.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
If you're interested in cholesterol support and want to try a seaweed extract, this product has some evidence behind it — but long-term safety and iodine content aren't well studied. Pregnant people should avoid it, and those breastfeeding should as well.
Talk with your doctor or pharmacist about whether this is right for you, especially if you plan to take it regularly or have a history of thyroid issues.
