What SeaChange Biochemistry does
SeaChange Biochemistry is a Halifax, Canada-based ingredient biotechnology company founded in 2020 that develops and supplies clinically validated, seaweed-derived bioactive compounds for the wellness, cosmetics, nutraceutical, and functional food and beverage industries. The company operates a proprietary, patent-pending extraction platform called SeaQuence™, which uses green chemistry principles and CO2 freeze drying to sequentially extract polyphenols, fucoidan, beta-glucans, and stem cell activators from organic wild-harvested Nova Scotia seaweed — reportedly eliminating up to 90% of the waste generated by conventional solvent-based extraction methods. Its flagship product brand, PolySea™, is positioned as a clinically proven anti-aging and immune-support ingredient available in three application formats: topicals, supplements, and functional food and beverage ingredients, with future pipeline ingredients including Fucoidan, Alginate, and PolySea™ Bioplastics targeting pharmaceutical and sustainable packaging markets.
The company has completed two human clinical trials through a research partnership with NIS Labs — a 20-participant placebo-controlled, randomized, double-blind, cross-over study for ingestibles and a 60-participant 9-week study for topicals in women aged 30-50 — producing quantifiable claims including 8X antioxidant activity versus leading extracts, 10X antioxidant power versus elderberry, 23% reduction in fine lines, 37% reduction in wrinkles, 48% increase in skin hydration, and rapid immune activation within 1-2 hours of consumption. The business model is primarily B2B enterprise field sales to cosmetics brands, nutraceutical companies, and functional food and beverage manufacturers under quote-based multi-year contracts, supplemented by a direct-to-consumer channel selling finished PolySea products through the company website. The company is founder-led by CEO Sabrena MacKenzie, a marine scientist and biochemist, with 1-10 employees and minimal disclosed external capital (a $25,000 Ocean Startup Project grant in 2020 and an undisclosed follow-on grant in 2021).

SeaChange Biochemistry competitors and assessment
Company assessmentBroad incumbents
- dsm-firmenich: Global nutrition, health, and personal care ingredients major with algae-derived and marine-source bioactives. Competes for the same cosmetic and nutraceutical customers as SeaChange, albeit across a much broader ingredient portfolio.
- CP Kelco: Global leader in hydrocolloids including alginate and specialty biopolymers. Comparable as a supplier of seaweed-derived functional ingredients to food, beverage, and personal care manufacturers, but at significantly larger scale and broader portfolio.
- Kerry Group: Global taste and nutrition company supplying functional ingredients (including marine-sourced proteins and extracts) to F&B and supplement customers. Comparable as an incumbent B2B ingredient supplier serving the same functional wellness end markets.
- IFF (Health & Biosciences / DuPont N&B legacy): Large diversified ingredient supplier with a portfolio that includes seaweed-derived hydrocolloids, gelling agents, and food/beverage functional ingredients. Comparable as an incumbent competing for the same B2B accounts that SeaChange targets.
Direct peers
- Algaia: France-based seaweed extract producer supplying alginates, fucoidans, and bioactive fractions to food, nutrition, and personal care brands. Closely parallels SeaChange's seaweed-derived bioactive ingredient model and customer base.
- Marinova: Australian specialty ingredient company producing high-purity fucoidan and polyphenol extracts from wild and cultivated seaweed for nutraceutical, cosmetic, and functional food applications — directly comparable to SeaChange's PolySea offering in both technology and end markets.
- Acadian Seaplants: Canadian marine plant processor (Nova Scotia-headquartered) producing seaweed extracts for agriculture, food, and personal care. Direct peer given shared Nova Scotia sourcing origin and overlapping B2B ingredient customer segments.
- Ocean Harvest Technology: Ireland-based producer of seaweed-based ingredient blends for animal nutrition and human functional foods. Comparable ingredient supplier targeting B2B nutrition customers, though with a different seaweed feedstock portfolio.
- Algea: Italian seaweed ingredient supplier (now part of Apulia Group) producing extracts and meals for agriculture, food, and cosmetics. Comparable B2B seaweed ingredient model, although broader and more commodity-oriented.
- Seagarden: Norwegian supplier of marine-derived bioactive ingredients (including fucoidan) for cosmetics and nutraceuticals. Comparable to SeaChange on technology (cold-process extraction) and target markets.
