About the Product
Marvelous Nutrition's Omega 3 is a food supplement in capsules of highly purified fish oil with a standard concentration of 18% EPA (eicosapentaenoic acid) and 12% DHA (docosahexaenoic acid), stabilized with D-alpha-tocopherol (Vitamin E) as an antioxidant to prevent the oxidation of polyunsaturated fatty acids. Per 2-capsule dose: 360 mg of EPA + 240 mg of DHA = 600 mg of long-chain omega-3 (EPA+DHA) — a value in line with the American Heart Association's daily recommendation of 1000 mg of EPA+DHA for general cardiovascular health, achieved with 2 capsules of 1000 mg of 18/12 fish oil. The highly advanced purification process ensures a product free from contaminants such as methylmercury, PCBs, dioxins, and other organic pollutants that accumulate in fish fatty tissues. 2 capsules/day with breakfast. Not vegan (fish-derived).
Benefits
EPA and DHA: the two long-chain omega-3 fatty acids with distinct and complementary biological functions:
Omega-3 is not a single compound but a family of polyunsaturated fatty acids characterized by the presence of a double bond at the omega-3 position (third carbon from the terminal methyl group). The two most biologically active and well-studied members are EPA (C20:5 n-3) and DHA (C22:6 n-3), both long-chain and exclusively of marine origin (fatty fish, algae). Alpha-linolenic acid (ALA, C18:3 n-3) present in plant sources (flaxseed, chia, walnuts) is the precursor, but the conversion rate of ALA to EPA and DHA in the human body is very limited (< 5% conversion of ALA to EPA and < 0.5% conversion to DHA), making direct supplementation with EPA and DHA from marine sources the only reliable way to ensure adequate levels of these long-chain fatty acids in tissues. EPA and DHA have distinct and complementary biological functions: EPA is the precursor of anti-inflammatory eicosanoids of series 3 (prostaglandin E3, thromboxane A3, leukotriene B5), while DHA is the main structural component of cell membranes in the central nervous system and retina.
Cardiovascular health: the application with the longest and most extensive evidence base:
The relationship between EPA+DHA consumption and cardiovascular health has one of the largest epidemiological and clinical evidence bases in all of nutrition. The mechanisms are multiple and well-characterized: EPA and DHA reduce plasma triglycerides by 20 to 50% (dose-dependent, at doses of 2 to 4 g/day of EPA+DHA), inhibiting hepatic VLDL synthesis and increasing triglyceride clearance by the endothelium via lipoprotein lipase activation. EPA competes with arachidonic acid (AA, omega-6) for the COX-2 enzyme, producing thromboxane A3 (much less potent than AA-derived thromboxane A2) and thereby reducing platelet aggregation and the risk of arterial thrombosis. DHA reduces the viscosity of erythrocyte membranes, improving red blood cell deformability and microcirculation. EFSA has approved health claims for contribution to the maintenance of normal blood triglyceride concentrations (EPA+DHA, 2 g/day) and contribution to the maintenance of normal blood pressure (EPA+DHA, 3 g/day).
Anti-inflammatory effects: the most relevant mechanism for athletes:
EPA and DHA have systemic anti-inflammatory effects through multiple mechanisms. EPA is the direct precursor of resolvins E (resolvin E1, E2, E3) and protectins, specialized pro-resolving lipid mediators (SPMs) that actively promote the termination of the inflammatory response and the restoration of tissue homeostasis. DHA is the precursor of resolvins D and neuroprotectins/protectins. These mediators act on specific receptors (GPR32, ChemR23, LTB4R2) that signal macrophages, neutrophils, and other immune cells to terminate the inflammatory response and promote the phagocytosis of cellular debris and tissue regeneration. For athletes undergoing intense training with exercise-induced muscle damage (DOMS, post-workout inflammation), omega-3s can contribute to faster recovery by modulating the post-exercise inflammatory response. The meta-analysis by Jouris et al. (2011) documented that omega-3 supplementation significantly reduced delayed onset muscle soreness (DOMS) after eccentric exercise compared to placebo.
Brain and cognitive health: the structural role of DHA in the central nervous system:
DHA is the most abundant polyunsaturated fatty acid in the human brain, accounting for ~40% of polyunsaturated fatty acids in the cerebral cortex and ~60% of polyunsaturated fatty acids in the retina. Its presence in neuronal and synaptic membranes is essential for the fluidity and flexibility of neural membranes, which determine the speed of nerve impulse conduction and the efficiency of synaptic transmission. Epidemiological studies consistently associate higher DHA intake with less age-related cognitive decline, lower incidence of depression, and reduced risk of dementia. EFSA has approved the health claim that DHA contributes to the maintenance of normal brain function (250 mg DHA/day) and to the maintenance of normal vision (250 mg DHA/day).
Visual health: DHA in the retina:
The retina is the tissue with the highest concentration of DHA in the human body. Retinal photoreceptors (rods and cones) are composed of DHA-rich membranes that ensure the fluidity and flexibility necessary for efficient photoconversion (rhodopsin and cone opsins require highly fluid membranes for their conformation and activation by photons). Dietary DHA deficiency is associated with lower visual acuity and age-related macular degeneration (AMD), one of the leading causes of blindness in developed countries.
D-alpha-tocopherol (Vitamin E): the antioxidant protector of EPA and DHA:
EPA and DHA are highly polyunsaturated fatty acids (with 5 and 6 double bonds respectively) and extremely susceptible to lipid peroxidation — both in the product during storage and in tissues after absorption. D-alpha-tocopherol (the natural and most bioactive form of vitamin E) is incorporated into the formula as a protective antioxidant: it donates electrons to peroxyl radicals (ROO•) that attack the double bonds of EPA and DHA, interrupting the lipid peroxidation chain. This antioxidant stabilization is essential both for product quality (prevents fish oil rancidity during shelf life) and for in vivo protection of EPA and DHA-rich tissues against oxidative stress.
Highly advanced purification: the guarantee of absence of contaminants:
Fatty fish, the source of fish oil, are often contaminated with persistent organic pollutants (POPs) such as PCBs (polychlorinated biphenyls), dioxins, furans, and methylmercury (MeHg), which bioaccumulate in fatty tissues along the marine food chain. Marvelous Nutrition's fish oil purification process uses molecular distillation and/or adsorption chromatography to remove these contaminants, ensuring levels below EU regulatory limits and GOED (Global Organization for EPA and DHA Omega-3s) standards. Advanced purification is also necessary to eliminate the fishy taste and odor often associated with lower-quality fish oils.
Uses
Recommended dose: Take 2 capsules with breakfast, with food. Taking it with a meal that contains some fat improves the absorption of EPA and DHA (which require the presence of bile salts and pancreatic lipase for micelle formation and intestinal absorption). For more pronounced anti-inflammatory effects and triglyceride reduction, higher doses (3 to 4 g/day of EPA+DHA, equivalent to 6 to 8 capsules of this formulation per day) are the most clinically studied, but should be taken under medical supervision at this dose level.
