**4. Anti-diabetic potentials of marine algae**

Marine seaweeds have been widely studied for their anti-diabetic potential through different mechanisms due to bioactive secondary metabolites. Several *in-vitro* and *in-vivo* studies have been conducted so far to confirm the hypoglycemic effect of marine algae in addition to its ability to suppress diabetic complications. This section emphasizes the anti-diabetic potential of marine brown, red, and green seaweeds through diverse mechanisms.
