Omega-3 fatty acids EPA and DHA become part of cell membranes and provide precursors for specialized pro-resolving mediators, including resolvins, protectins, and maresins. In this clip from Dr. Rhonda Patrick's appearance on Huberman Lab, she explains how these pathways help coordinate the resolution phase of inflammation. Fish and omega-3 supplements can both provide EPA and DHA, while the appropriate source and dose depend on diet, baseline status, product quality, and health context.
A post hoc DO-HEALTH analysis studied 777 generally healthy Swiss adults with a mean age of about 75. One gram per day of marine omega-3 produced small favorable changes in three DNA-methylation aging measures over three years. Vitamin D and a home exercise program added benefit on one clock. Separate analyses found lower odds of prefrailty and fewer invasive cancers with the full three-part intervention, making the combined healthy-aging approach a useful area for continued study.

Cardiovascular effects depend strongly on formulation and population. Purified prescription EPA reduced cardiovascular events in selected high-risk, statin-treated patients with elevated triglycerides, while broader EPA-DHA trials have produced different results. Prescription omega-3 also lowers very high triglycerides. Baseline lipids, atrial-fibrillation history, bleeding risk, medicines, and the amount of EPA and DHA in the product should guide higher-dose use. [4] [5] [6]

Dr. Andrew Huberman: After our prior conversation, I began taking prescription omega-3 under medical supervision. My lab results changed, but that personal response is not trial evidence or a general recommendation.
Dr. Rhonda Patrick: Prescription omega-3 lowers very high triglycerides. It can also raise LDL cholesterol in some people and carries atrial-fibrillation and bleeding cautions. Lovaza is not approved as a general longevity or inflammation drug.
EPA and DHA become part of cell membranes and provide precursors for specialized pro-resolving mediators, including resolvins, protectins, and maresins. These pathways help resolve inflammation. No comparative clinical trial supports calling omega-3 the most powerful natural compound.
In a post hoc DO-HEALTH analysis of 777 generally healthy adults age 70 and older, one gram per day of marine omega-3 produced small favorable changes in three DNA-methylation aging measures over three years. Vitamin D and a simple home exercise program added benefit on one clock. The estimated differences were about 2.9 to 3.8 months. These biomarkers do not prove rejuvenation, longer life, or clinical benefit.
Separate DO-HEALTH analyses found 39 percent lower odds of prefrailty and 61 percent lower invasive-cancer hazard with all three interventions combined. These were secondary or exploratory findings. The clock change did not cause or “translate into” those outcomes. The main DO-HEALTH trial did not improve its six prespecified primary outcomes.
Cardiovascular evidence depends on the product and population. Purified prescription EPA reduced events in selected high-risk patients with elevated triglycerides. Several mixed EPA-DHA trials in broader populations were null. Higher doses can increase atrial-fibrillation risk.
An Omega-3 Index measures EPA and DHA in red blood cells. Eight percent is a proposed lower-risk target, not a universal treatment threshold. Two grams per day does not move everyone from 4 to 8 percent. Response depends on baseline status, body size, formulation, diet, adherence, and genetics.
Observational studies associate higher omega-3 blood levels with lower mortality and sudden cardiac death. They do not prove that supplementation adds five years of life or prevents 90 percent of sudden deaths.
Lower-mercury fish remains a recommended nutrient source. Supplements can provide EPA and DHA when fish is unsuitable, but they do not replace fish protein, selenium, vitamin D, or other nutrients. Product quality and oxidation vary.
Dr. Andrew Huberman: My vitamin D and Lovaza doses are personal and guided by blood work.
Dr. Rhonda Patrick: High-dose vitamin D is not a general anti-aging protocol. Five thousand to eight thousand IU per day exceeds the standard adult upper intake level and requires clinician-guided monitoring when used.
