SuanNutra USA, a Glen Rock-based innovator in the nutraceutical sector, announced Wednesday that it finalized an exclusive distribution agreement with Spanish biotech leader Fitoplancton Marino, S.L. The deal grants SuanNutra the rights to provide TetraSOD®—a highly concentrated, science-backed marine bioactive complex—to the North American market.
The partnership brings one of the world’s most potent antioxidant ingredients to U.S. shores, targeting the fast-growing categories of metabolic health, athletic performance, and “ageless” living.
TetraSOD® is derived from the microalgae Tetraselmis chuii, a strain originally isolated in Europe’s protected Doñana Natural Park. Unlike traditional antioxidants that neutralize free radicals directly, TetraSOD® acts as an “indirect antioxidant.” It triggers the body’s internal defense systems by activating the NRF2 and SIRT1 pathways, which are critical for cellular repair and protection against inflammation.
“We invested more than 20 years in developing this ingredient and revealing the science behind it,” Carlos Unamunzaga, CEO of Fitoplancton Marino said. “Now, everything is aligned for U.S. consumers to adopt the mindset of agelessness.”
SuanNutra USA leadership believes the ingredient’s clinical track record will set it apart in a crowded marketplace. TetraSOD® is backed by 17 peer-reviewed studies and 10 patents. Most notably, it demonstrates efficacy at a daily dose of just 25 mg, a fraction of the amount required by many conventional supplements.
“With its solid clinical evidence and benefits perceived by subjects in under a month, we believe TetraSOD® has the potential to become a true hero ingredient in the U.S. market,” Anthony Weston, CEO of SuanNutra USA said.
Key Clinical Findings Include:
- Physical Performance: Improvements in aerobic capacity and oxygen uptake (VO2 max) within just 14 days.
- Recovery: Significant reduction in muscle damage markers following high-intensity workouts.
- Healthy Aging: Recent March 2026 research indicates the ingredient helps protect telomere length in human cells.
- Gut Health: Preclinical studies suggest it acts as a prebiotic, increasing microbial diversity in the colon.
The microalgae is cultivated using a patented, sustainable process in closed outdoor bioreactors in Spain. This controlled environment allows for a record-breaking concentration of Superoxide Dismutase (SOD). The process involves no chemical extraction; the algae is simply harvested and dried into a fine powder, preserving its diverse matrix of vitamins, pigments, and fatty acids.
The arrival of TetraSOD® in New Jersey comes at a time of increased interest in GLP-1 support and metabolic health. SuanNutra USA plans to market the ingredient to supplement manufacturers across the country, positioning it as a versatile component for active nutrition and longevity formulas.
TetraSOD® already holds Self-GRAS status in the U.S. and has become a top-selling nutraceutical in Japan. By securing these rights, Glen Rock’s SuanNutra USA cements its role as a primary gateway for advanced, sustainable European biotech entering the American wellness industry.
