Research conducted by DuPont (Wilmington, DE) suggests that EPA oil derived from genetically modified yeast bears a safety profile 'comparable to that of [Generally Recognized as Safe] GRAS fish oil.' The study, published in the journal Regulatory Toxicology and Pharmacology, investigated the effects of EPA oil from genetically modified Yarrowia lipolytica. For 90 days, rats were assigned placebo; 98, 468, or 976 mg of the yeast; or GRAS fish oil daily by oral gavage.

The study, published in the journal Regulatory Toxicology and Pharmacology, investigated the effects of EPA oil from genetically modified Yarrowia lipolytica. For 90 days, rats were assigned placebo; 98, 468, or 976 mg of the yeast; or GRAS fish oil daily by oral gavage.
In checking for cholesterol markers, lower total cholesterol and low-density lipoprotein (or 'bad'ÃÂ cholesterol) levels were noted in the medium and high yeast groups and fish oil group. High-density lipoprotein (or 'good'ÃÂ cholesterol'ÃÂ) was lowered in the high yeast and fish oil groups only at early time points, note the researchers.
Regarding adverse health effects, nasal lesions were observed in rats fed high and medium yeast, and fish oil'”reportedly due to oil in the nasal cavities. Outside of this observation, no other side effects were reported.
'The safety profile of EPA oil was comparable to that of GRAS fish oil,'ÃÂ wrote the study...s lead author. 'These results support the use of EPA oil produced from yeast as a safe source for use in dietary supplements.'ÃÂ

Recent animal study finds that Lysoveta may help reduce neonatal brain injury
July 17th 2024A recent animal study found that lysophosphatidylcholine (LPC)-bound omega-3 long-chain polyunsaturated fatty acids (LCPUFAs), marketed as Lysoveta by Aker BioMarine, protected against neonatal hypoxic-ischemic (HI) brain injury in mice.
Krill oil supplementation raises Omega-3 Index of Lupus patients in recent study
July 16th 2024The study was conducted at 20 research centers in the United States by Aker BioMarine and the Lupus Clinical Investigators Network with oversight by Lupus Therapeutics, the clinical research affiliate of the Lupus Research Alliance.
Meta-analysis does not find increased risk of bleeding events from omega-3 PUFA consumption
July 8th 2024Researchers reviewed 11 studies and found that there was no difference in the incidence of bleeding events between patients receiving omega-3 PUFAs and those not receiving them. High dose EPA consumption was associated with an elevated but modest risk.
Recent review states that pentadecanoic acid may support cellular stability for better longevity
June 25th 2024According to the paper’s author, Stephanie Venn-Watson, DVM, MPH, deficiency in pentadecanoic acid of ≤0.2% total circulating fatty acids increases the risk of ferroptosis, which a type of cell death cause by the peroxidation of fragile fatty acids in cell membranes that combines with iron thus increasing reactive oxygen species, and disabling mitochondria.
