About Brown Seaweed Extract (InSea2)
Patented combination of two brown seaweeds (Ascophyllum nodosum + Fucus vesiculosus, branded InSea2/InnoVactiv) standardized for phlorotannins, which inhibit alpha-amylase and alpha-glucosidase. Several small industry-funded RCTs show reduced post-meal blood glucose spikes when taken before carb-heavy meals. Evidence is promising but comes primarily from manufacturer-sponsored trials; independent replication is limited.
