Evidence strength

WEAKLIMITEDMODERATESTRONGVERY STRONG
What the evidence supports: very little — human trials on sea moss itself are essentially absent.
This scores how well-supported the claim above is — not how much benefit you personally would get. A high score on a narrow claim does not extend to everything the product is marketed for.
How long to take it
Not recommended for daily use without knowing the iodine content per serving.
Who it's actually for
Limited justification. The '92 minerals' marketing claim tells you nothing about amounts.
Safe upper limit

Seaweeds can contain very high and unpredictable amounts of iodine. Excess iodine can trigger or worsen thyroid dysfunction, both overactive and underactive. Seaweeds can also accumulate heavy metals from seawater.
