dried kelp

Botanical

Kelp is pet food's iodine dial — genuinely nutritious seaweed whose one real variable is how much thyroid fuel it carries from batch to batch.

Also appears on labels as: kelp · kelp meal · sea kelp · seaweed meal · ascophyllum nodosum

What it is

Dried brown seaweed (often Ascophyllum nodosum), ground as kelp meal. Its minerals are the point, and iodine is the headline: kelp is among the most iodine-dense ingredients in any food chain, and natural batches vary widely. Iodine drives thyroid hormone production — necessary in a band, unhelpful in chronic excess.

Why it's in pet food

A natural trace-mineral source with an ocean-wellness halo, plus a specific niche: Ascophyllum nodosum is the algae behind dental-plaque marketing, where the evidence is modest but not empty. Reputable formulators assay kelp's iodine and dose accordingly; that quality-control sentence is doing more work than the label shows.

How Bowlmark scores it

Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.

Neutral in the engine: no bonus seat, no deduction, no flag — mineral variability is a formulation-quality question the label alone can't settle, so the score doesn't pretend to. The practical read: kelp far down a list from a reputable maker is fine; kelp as a do-it-yourself topper powder is an unmeasured iodine dose, which is the version worth declining.

For cats

Cats and chronic iodine excess is a live research conversation in feline hyperthyroidism — unresolved, but reason enough to keep cats' kelp exposure to properly formulated foods rather than supplements.
