An Ancient Staple, Decoded
For centuries, the inhabitants of Okinawa and South Korea—some of the longest-lived people on Earth—have consumed brown seaweed as a daily staple. While they understood the result (vitality), they did not understand the mechanism. Modern science has isolated the active compound responsible: Fucoidan.
Fucoidan is a complex, sulfated polysaccharide found in the cell walls of brown seaweeds like Fucus vesiculosus. It acts as the plant's immune system, protecting it from marine pathogens and environmental stress. When ingested by humans, it acts as a "biological response modifier," engaging directly with our cellular machinery to regulate inflammation, immunity, and genomic repair.
The Sirtuin Activator.
Research has moved beyond general health into epigenetics. Fucoidan is now identified as a precision-guided activator of SIRT6.
The Discovery (In Vitro)
Finding: Fucoidan increased SIRT6 activity by 355-fold in lab assays.
Specificity: Highly specific to SIRT6, with no effect on SIRT1 or SIRT2.
Read Study: Rahnasto-Rilla et al.The Breakthrough (In Vivo)
The Holy Grail. The study confirmed Fucoidan activates both of SIRT6’s enzymatic engines: the Deacetylase Engine (Metabolism) and the critical Mono-ADP-ribosylase Engine (DNA Repair).
This "Dual-Engine" activation allows it to silence "Junk DNA" (LINE1 elements) and reverse epigenetic age.

The Clinical Dossier.
We don't sell hope. We highlight peer-reviewed human trials focusing on oncology, immunity, and metabolic health.
Metastatic Colorectal Cancer
Protocol: Low-Molecular-Weight Fucoidan vs. Placebo with chemotherapy.
Success Rate: 92.8% vs 69.2%
Rectal Cancer Quality of Life
Protocol: Supplementation alongside chemoradiotherapy.
Result: Less fatigue & skin toxicity.
Cholesterol Modulation
Protocol: 12-week supplementation.
Result: Increased HDL ("Good") Cholesterol.
Vaccine Response in Elderly
Protocol: Intake prior to flu vaccination.
Result: Enhanced antibody production.
Other Mechanisms.
Inflammation Control
Inhibits the NF-κB pathway, reducing pro-inflammatory cytokines like TNF-α and IL-6 to cool systemic inflammation.
Immune Surveillance
Activates Natural Killer (NK) cells and macrophages, increasing the body's ability to detect and clear "zombie" cells.
Gut Renovation
Acts as a prebiotic, feeding beneficial bacteria like Ruminococcaceae to produce SCFAs that repair the gut lining.
Safety & Specificity.
Not all Fucoidan is created equal.
The Source
Prime Ageing utilizes Fucus vesiculosus. This species has a specific molecular structure (α-(1→3) linked fucose) that is highly bioactive.
Regulatory
High-purity extracts from Fucus vesiculosus are GRAS (FDA) and Novel Food approved (EU).
Contraindications
Due to mild anticoagulant properties, do not take concurrently with blood-thinners like Warfarin.
The Verdict
Fucoidan is not a "wellness" ingredient. It is a research-backed molecule with a dual scope of investigation:
- The Architect (Genomic Stability): Identified in studies as a potent activator of the SIRT6 "Longevity Gene"—the protein responsible for maintaining DNA stability and epigenetic precision.
- The Engineer (Systemic Support): The subject of emerging research into "Senolytic" pathways, supporting the body’s ability to clear senescent ("zombie") cells and manage inflammatory noise.
