Episode 5: Sabrena MacKenzie – Seaweed Science, A Natural Breakthrough in Skincare and Wellness

In this episode of the Enjoy Life Healthier™ podcast, host Jason Kam speaks with Sabrina McKenzie, a seaweed biochemistry expert and founder of SeaChange Biochemistry. They discuss the untapped potential of marine-based compounds in human health, the science behind brown seaweed’s unique bioactives, and how Sabrina’s patented extraction method is revolutionizing the supplement and skincare industries.

Sabrina shares her journey from working in Canada’s National Research Council to launching her own company focused on sustainable seaweed innovation. She highlights breakthrough clinical research on PolyC®, a seaweed-derived ingredient that’s shown rapid immune activation, antioxidant protection, and even stem cell stimulation when taken orally. Topically, the compound has led to dramatic improvements in wrinkles, hydration, and age spots—offering a powerful, all-natural solution in the anti-aging space.

Takeaways

• Brown seaweed contains powerful compounds like unique polyphenols and fucoidan that offer immune and skin benefits.

• Sabrina’s team developed a green chemistry extraction process that preserves the potency of marine bioactives.

• PolyC® begins working in as little as two hours after ingestion, offering fast-acting immune and antioxidant effects.

• Clinical trials showed over 200% improvements in skin smoothness and reduction in crow’s feet with topical use.

• The compound activates the body’s own stem cells to support tissue repair and regeneration.

• Early data suggests potential benefits for smokers due to its ability to combat free radical damage.

• The topical formulation was originally an accident—sparked by anecdotal evidence from a factory worker with eczema.

• Seaweed’s survival in extreme intertidal conditions makes it uniquely suited to help human skin retain moisture.

• Participants in clinical studies reported highly specific, positive results—demonstrating both scientific and real-world efficacy.

• Seaweed-based ingredients are poised to become game-changers in both the wellness and skincare markets.
