“A higher omega-3-index quintile was associated with lower all-cause mortality risk, but the estimated years of life were model-derived comparisons between quintiles, not observed gains from raising an index from 4% to 8%.”

“Because red blood cells turn over slowly, the test provides a longer-term view of marine omega-3 status than a recent meal and gives people a measurable way to evaluate diet or supplementation.”

“A later Framingham analysis followed 2,240 adults for 11 years and found that a red-cell fatty acid model including the Omega-3 Index predicted all-cause mortality about as well as a model using several standard cardiovascular risk factors.”

“A randomized-trial meta-analysis found a higher atrial-fibrillation risk with marine omega-3 supplementation, with a stronger signal at doses above 1 gram per day; the included populations generally had cardiovascular disease or elevated cardiovascular risk.”

“EPA and DHA play particularly important roles in heart health because they participate in pathways involved in the production of hormones that regulate blood clotting and inflammation, help maintain healthy heart rhythms, and influence the contraction and relaxation of arteries.”

“The phospholipid form of DHA, abundant in fish roe, directs DHA into the brain via active transport, thus bypassing the reliance on passive diffusion. In this clip, Dr. Rhonda Patrick discusses DHA bioavailability and describes her personal DHA regimen, which includes dietary and supplemental sources of omega-3 fatty acids.”

“Not only is salmon roe a good source of DHA, it also provides protein, vitamins, minerals, and astaxanthin – an antioxidant compound that gives salmon its reddish or pinkish tint. In human studies, astaxanthin reduces biomarkers of oxidative stress.”

“For omega-3s, salmon provides EPA and DHA in a whole-food matrix, but fish can also contain mercury and microplastics; well-characterized purified products may reduce exposure to some contaminants but are not nutritionally identical to fish.”

“In this clip from Dr. Rhonda Patrick's presentation at the Vibrant Wellness Longevity Summit, she explains how the Omega-3 Index measures EPA and DHA in red-blood-cell membranes as a longer-term marker of omega-3 status.”

“Pooled intervention data suggest that about 1.5 to 2 grams of combined EPA and DHA per day can raise the Omega-3 Index in many adults over several months, although individual responses vary.”
