Global warming has affected the distribution of organisms for decades and has displayed rapid ascent recently. Research into the effects on tropical organisms are vital. Padina boryana is a resourceful marine microalgae in the Maldives Sea in the Laccadive region. A 70% ethanol extraction (PBE) of this seaweed was used to investigate its antioxidant potential. Both in vitro and in vivo models were implemented. PBE exhibited protective potential against H₂O₂ induced apoptosis. ROS levels were suppressed due to PBE. PBE expressed a cytoprotective nature. In vivo experiments involving the zebra fish model conformed its validity. The antioxidant efficacy of PBE was dose dependent. Study outcomes suggest PBE has potential as a novel and valuable marine resource to aid the functional food and cosmeceutical industries.
