The Ancient Superfood: Alaskan Cod Liver Oil’s Benefits for Heart, Vision, and Joint Health
For centuries, cod liver oil has been revered as a natural tonic. Today, sustainably sourced Alaskan cod liver oil remains a compact source of long-chain omega-3s and fat-soluble vitamins that can support cardiovascular health, vision, and joint comfort when used appropriately.
Sustainable Sourcing: A Commitment to Quality
Line-caught from cold Alaskan waters, premium cod liver oil reflects best-practice fisheries and careful processing to retain native nutrients—vitamin A and D, plus omega-3 fatty acids (EPA, DHA; often with measurable DPA). Traceable sourcing and low-temperature handling help preserve potency.
Key Active Compounds
Vitamin A (~1,200 µg/serving, as labeled) supports ocular surface integrity and night vision. See mechanistic and clinical context in recent reviews (Sajovic 2022; Thirunavukarasu 2022).
Vitamin D contributes to bone and immune function; cod liver oil is a traditional source alongside sunlight exposure.
Omega-3s (EPA, DHA, DPA) are the cardiometabolic workhorses; DHA also concentrates in the retina and brain. Cardiovascular outcome evidence for omega-3s is summarized in contemporary reviews and meta-analyses (Khan 2021; Patel 2021; NIH overview ODS Fact Sheet). For DPA specifically, human data are more limited—see review (Yazdi 2014).
Specialized Pro-Resolving Mediators (SPMs) are enzymatic derivatives of omega-3s that actively resolve inflammation. Foundational work: (Serhan 2014; open-access summary Serhan 2014 (PMC)). Marine oil supplementation can raise circulating SPMs (Souza 2020), and an RCT in knee OA reported pain reduction with SPM concentrate (Möller 2023).
Health Benefits Breakdown
Heart Health
Long-chain omega-3s are linked to favorable triglyceride effects and cardiovascular risk reduction in several analyses; EPA-only strategies often show the strongest signal (Khan 2021; Patel 2021). As a whole-food oil, cod liver oil provides mixed EPA+DHA (and some DPA); use aligns with dietary omega-3 guidance (NIH ODS).
Vision Support
Preformed vitamin A supports rhodopsin regeneration and low-light vision; deficiency classically causes night blindness (Sajovic 2022). DHA also contributes structurally to photoreceptor membranes.
Joint Health
Omega-3s and their SPM derivatives can help balance inflammatory pathways relevant to joint comfort; see mechanistic overview and emerging human data (Serhan 2014; Möller 2023).
Easy Daily Usage
Suggested use: 1 teaspoon daily (about 5 mL), preferably with meals. Bottle size: 200 mL (~40 servings). Note: The labeled vitamin A (~1,200 µg/serving) is below the adult UL (3,000 µg RAE/day) but is significant—avoid stacking multiple high-A supplements; pregnant individuals should consult their clinician.
Quality Assurance
Each lot emphasizes traceable sourcing, sustainable harvest, gentle purification, and third-party testing for oxidation and contaminants—key for maintaining nutrient integrity.
