The Claim
Farmed Scottish seaweed species Alaria esculenta and Saccharina latissima contain significantly higher iron concentrations (up to 83% of the Reference Nutrient Intake per 5g portion) than wild-caught specimens of the same species.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Farmed Scottish seaweed Alaria esculenta and Saccharina latissima have higher iron content per gram than wild seaweed of the same species, with a 5g portion providing up to 83% of the recommended daily iron intake.
See the scientific wording
Farmed Scottish seaweed species Alaria esculenta and Saccharina latissima contain significantly higher iron concentrations (up to 83% of RNI per 5g portion) than wild counterparts, suggesting farming may enhance iron content, though this requires confirmation with larger samples.
Farmed seaweed absorbs more iron from the water because it grows in environments where iron is deliberately available, and its cells store more of it compared to wild seaweed that grows in less predictable nutrient conditions.
What the research says
1 studyScientists found that seaweed grown on farms in Scotland can have a lot of iron — up to 83% of what you need in a tiny 5g serving — and farming might make it even richer than wild seaweed. This could help people who don’t eat meat get enough iron from their food.
