Calanus Oil (Calanus finmarchicus)

Calanus Oil is a marine lipid extract derived from the copepod Calanus finmarchicus, with a distinct lipid composition differing significantly from conventional fish oils. Primary lipid class: wax esters (approximately 70-80% of total lipids), which is unique among commercial marine oils that are predominantly triglycerides. Omega-3 fatty acids: EPA (eicosapentaenoic acid) approximately 7-10% of total fatty acids, DHA (docosahexaenoic acid) approximately 6-9% of total fatty acids, with omega-3s predominantly esterified in wax ester form rather than triglyceride or phospholipid form, resulting in slower digestion and potentially prolonged absorption. Stearidonic acid (SDA, 18:4n-3): approximately 4-6%, a metabolic precursor to EPA. Astaxanthin: approximately 300-500 mcg per gram of oil, a potent carotenoid antioxidant naturally esterified within the oil matrix, providing significantly higher antioxidant capacity than fish oil. Vitamin E (tocopherols): naturally present at low but functional concentrations (approximately 0.5-1 mg per gram), contributing to oxidative stability. Fatty alcohol components (from wax esters): primarily phytol-derived and long-chain fatty alcohols (C20-C22), which contribute to the unique metabolic processing of this oil. Phospholipids: minor fraction (approximately 5-10%), including phosphatidylcholine-bound EPA and DHA. Caloric density: approximately 9 kcal per gram as a lipid. Bioavailability note: The wax ester form results in slower hydrolysis in the gastrointestinal tract compared to triglyceride-form omega-3s; however, preclinical and clinical data suggest effective systemic absorption with potentially sustained plasma omega-3 elevation. No significant protein, carbohydrate, or dietary fiber content.
