3838 results about "Fish oil" patented technology

Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body and improve hypertriglyceridemia. There has been a great deal of controversy in recent years about the role of fish oil in cardiovascular disease, with recent meta-analyses reaching different conclusions about its potential impact. The most promising evidence supports supplementation for prevention of cardiac death.

Anti-inflammatory supplement compositions and regimens to reduce cardiovascular disease risks

Disclosed are improvements in human nutrition involving a unique combination of natural products constituting anti-inflammatory compositions which can reduce cardiovascular disease risks as well as play a positive role in other conditions and diseases for which key indicators, especially selected from the group consisting of C-reactive protein (CRP) levels, cyclooxygenase-2 (COX-2), 5-lypoxygenase (5-LOX) expression and prostaglandin E2 (PGE-2) biosynthesis or any combination of these, are indicators. Therapeutic compositions preferably comprise curcumin, bilberry extract, grape seed extract, green tea extract and apple extract, in effective amounts individually and combined to provide a therapeutically significant reduction in one or more key indicators. Another exemplified therapeutic composition comprises: omega-3 rich refined fish oil, resveratrol, blueberry extract, grape seed extract, green tea extract and gamma and / or delta tocopherol, in effective amounts individually for the above benefits.

Production of ultrapure epa and polar lipids from largely heterotrophic culture

Eicosapentaenoic acid (EPA) compositions and EPA-rich polar lipids for prophylactic or therapeutic applications are described. Production from certain cultured micro-organisms (like Nitzschia laevis) promotes synthesis of EPA, including polar lipids including EPA. The EPA-rich polar lipids themselves may be used as polar compounds. EPA can be selectively hydrolysed from particular positions in isolated polar lipids by lipase activity, then optionally further purified. The process bypasses reliance on diminishing fish stocks and on physico-chemical processes that may not adequately separate desirable n-3 HUFAs from unwanted products like DHA also found in fish oil and cultured organisms.
