Sargassum and kelp are both brown seaweeds, but they are not interchangeable raw materials.
The seaweed source is only one variable
Species, harvest location, rinsing, extraction, fermentation, concentration and application rate can all change the finished product. A result reported for one kelp extract should not automatically be treated as proof for a different Sargassum formulation.
Why Florida Root & Tide uses Sargassum
Our product is shaped by a locally available coastal resource and a small-batch process. We describe published seaweed research separately from claims about our own finished formulation.
How to compare products
Look for clear label directions, transparent ingredients, realistic claims and a manufacturer that distinguishes general research from product-specific testing.
