Nutricost is the cheap, easy way into the sea moss + bladderwrack + burdock trio: one concentrated capsule, made in a GMP-compliant, NSF-certified facility, at one of the lowest costs per serving in our nine-product lineup (~$0.28). For a category this hype-driven, a recognizable value brand with a real manufacturing-quality claim is a reasonable low-risk entry point.
We owe you a correction before the praise. An earlier version of this review attributed a far larger milligram figure to this listing, printed it in quotation marks, and ran a truth-check against it. We re-read the listing on 28 July 2026: that figure appears nowhere on it. We had invented it and then debunked our own invention, so we've removed it rather than reworded it — and we won't reprint it here, because a fabricated quote is no less fabricated for being quoted in its own correction. What the listing actually says is: "Delivers 400mg of 10:1 Irish Sea Moss extract per serving." That's 400mg of a concentrated extract, about 4,000mg raw-equivalent. The correction has been made everywhere it appeared, and the score has been rebuilt from the axes rather than reverse-engineered to a number we liked.
What's left is a decent capsule with one real gap. The sea moss amount is disclosed; the bladderwrack and burdock amounts are not, and no iodine content is declared — which matters because bladderwrack carries roughly seven times the iodine of Irish moss by weight, so the ingredient driving the thyroid risk is the one you can't quantify. It also doesn't say whether the sea moss is wildcrafted or pool-grown. None of that sinks it, but it does place it behind the picks that tell you exactly what you're swallowing: it lands at #3, not #1.
