  journal={Nutrition \& Dietetics},
Aim:  The aim of the present study was to determine the fatty acid composition of 19 dietary oil supplements that are commercially available in Australia, comparing findings with manufacturers' reported omega-3 fatty acid content. Methods:  Fifteen fish oil supplements and four non-fish oil supplements were obtained from Australian retail stores. Fatty acids were derivatised, and fatty acid methyl esters were quantitated using classical GC-flame ionisation detection methods. Composition… Expand
Content and composition of fatty acids in marine oil omega-3 supplements.
Content and composition of fatty acids in 46 commercially available marine oil omega-3 supplements are investigated by gas chromatography with flame ionization detection using the 200 m SLB-IL111 ionic liquid column and Contents of EPA and DHA met their respective label declarations in more than 80% of the products examined.

Fish oil supplements, oxidative status, and compliance behaviour: Regulatory challenges and opportunities
Most, although not all, of the fish oil supplements tested are compliant with the GOED oxidative quality standards, and it is clear that there should be a high level of inspection and control regarding authenticity, purity, quality, and safety in the processes of production and supply of dietary supplements containing fish oils.

Omega-3 Long-Chain Polyunsaturated Fatty Acid Content and Oxidation State of Fish Oil Supplements in New Zealand
Of the tested products, 72%, 86% and 77% complied with voluntary industry-set maximum limits on Peroxide Value (PV), para-Anisidine Value (p-AV), and TOTOX, respectively, and 91% of the products complied with EPA/DHA content claims, in stark contrast to a recently published assessment of fish oil supplements in New Zealand. Expand
Fish oil supplements in New Zealand are highly oxidised and do not meet label content of n-3 PUFA
Almost all fish oil supplements available in the New Zealand market contain concentrations of EPA and DHA considerably lower than claimed by labels, and the majority of supplements tested exceeded the recommended indices of oxidative markers. Expand
Application of Infrared Spectroscopy for Characterization of Dietary Omega-3 Oil Supplements
Fish oil dietary supplements have been linked with health benefits, due to high omega-3 concentration. The sources of these effects, polyunsaturated fatty acids such as eicosapentaenoic acid andExpand
Analysis of the Omega-3 Fatty Acids Content in Commercial Omega-3 Supplements in Arab Gulf Countries
The results demonstrate that omega-3 supplements sold in Arab Gulf Countries is not being properly controlled by manufacturers or government agencies and quality testing is needed to ensure compliance. Expand
Quality analysis of commercial fish oil preparations.
More stringent regulation is required for fish oil products after it was found that over half of the supplements did not meet their label claims for EPA and DHA, and a quarter exceeded recommended limits for peroxide value. Expand
Quality of Fish-Oil-Based Dietary Supplements Available on the Italian Market: A Preliminary Study
The global market of food supplements is growing rapidly with a large turnover. Fish oil supplements represent a significant part of this turnover as they are believed to have important healthExpand
Ingredient label claim compliance and oxidative quality of EPA/DHA omega-3 retail products in the U.S.
Abstract The 48 most widely sold retail EPA/DHA omega-3 fatty acid dietary supplements on the U.S. market were tested for EPA + DHA label claim compliance and for oxidative quality. Each product wasExpand
Marine oils: Complex, confusing, confounded?
There is a pressing need for clinical trials using marine oils whose composition has been independently verified and demonstrated to be minimally oxidised, as it is premature to conclude that n-3 PUFA rich supplements are ineffective. Expand


Dietary intake of long-chain ω-3 polyunsaturated fatty acids: contribution of meat sources
Meat is a major source of LCn3PUFA, particularly DPA, for most Australians, and when DPA is included in the definition of LCN3PUFAs, almost half the average adult intake ofLCn3 PUFA appears to originate from meat sources. Expand
Levels of Omega 3 fatty acids in Australian seafood.
Because most white table fish consumed by Australians are so low in fat they are actually a limited source of omega 3 fats, the amount of fish required to be consumed to provide 1 g of omega3 fatty acid per day ranged from 40 to 450 g. Expand
n-3 fatty acid dietary recommendations and food sources to achieve essentiality and cardiovascular benefits.
The evidence base supports a dietary recommendation of approximately 500 mg/d of EPA and DHA for cardiovascular disease risk reduction and treatment of existing cardiovascular disease, and a dietary strategy for achieving the 500-mg/d recommendation is to consume 2 fish meals per week. Expand
Determination of the fatty acid composition of saponified vegetable oils using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
The MALDI-TOFMS method could be used routinely to determine the qualitative fatty acid composition of vegetable oils, and, when fully validated by comparison with standard analytical methodologies, should provide a relatively fast quantitative measurement of fatty acid mixtures and/or soap formulations that contain saturated and unsaturated hydrocarbon moieties.

Scientific data indicate that the consumption of fish or fish oil containing omega-3 PUFAs reduces the risk of coronary heart disease, decreases mild hypertension, and prevents certain cardiac arrhythmias and sudden death. Expand
Distribution, interconversion, and dose response of n-3 fatty acids in humans.
It is concluded that the most predictable way to increase a specific long-chain n-3 fatty acid in plasma, tissues, or human milk is to supplement with the fatty acid of interest. Expand
Comparative quantitative fatty acid analysis of triacylglycerols using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and gas chromatography.
The ability of MALDI-TOFMS to detect low concentrations of fatty acids rendered it more sensitive than the GC methodology, particularly with regard to baseline resolution of unsaturated acids. Expand
Production of Lipids Rich in Omega 3 Fatty Acids from the Halotolerant Alga Dunaliella salina
The results obtained suggest that D. salina cells containing high amount of total lipid, rich in ω polyunsaturated fatty acids and antioxidant compounds in 3 unsaponifiable lipid fraction may be used as a supplemental ingredient or as a complete food to enhance the performance and state of the human body or improve a specific bodily function.

High-resolution (13)C nuclear magnetic resonance spectroscopy pattern recognition of fish oil capsules.
13C NMR spectroscopy, in conjunction with multivariate analysis of commercial fish oil-related health food products, have been used to provide discrimination concerning the nature, composition, refinement, and/or adulteration or authentication of the products. Expand
