The Omega-3 Protocol
Rhonda Patrick makes omega-3 fatty acids one of the few supplements with real longevity evidence: aim for an omega-3 index of 8% or higher. A higher index tracks with lower all-cause mortality in large studies; food sources like wild fish come first, and the well-absorbed triglyceride form beats cheap ethyl-ester fish oil.
Most people are low in the marine omega-3s EPA and DHA, and Rhonda Patrick treats correcting that as one of the highest-value, best-evidenced nutrition moves you can make. The target is an omega-3 index (the omega-3 percentage in your red blood cells) of 8% or higher, which is associated with lower all-cause mortality. For most people that means roughly 2 grams a day of EPA plus DHA, though Patrick personally takes around 4 grams, split EPA in the morning and DHA in the evening. Form and quality matter as much as dose.
Why it works▼
Test your omega-3 index
It is the only way to know if you are actually getting enough; response varies between people.
Get omega-3s from food first
Food delivers omega-3s in a well-absorbed form alongside other nutrients.
Add a quality fish oil to reach target
Most people cannot hit target from diet alone; supplementing closes the gap.
Choose triglyceride form, third-party tested
Cheap ethyl-ester and oxidised oils undercut the benefit; quality is not optional here.
Use algae oil if you do not eat fish
Algae oil delivers EPA/DHA directly, unlike ALA which barely converts.
Retest after a few months
It confirms your dose is actually working and lets you fine-tune.
- Anyone who eats little oily fish
- People focused on brain and heart healthspan
- Those who want evidence-led supplementation
- Vegans and vegetarians (via algae)
- Very high doses (10g+/day) may raise arrhythmia risk in some people, and omega-3 trials in established cardiovascular disease have been mixed; if you have heart disease or take blood thinners, talk to your doctor before high doses
- Quality varies enormously: ethyl-ester and oxidised fish oils undercut the benefit, so prioritise triglyceride form and third-party testing
- More is not automatically better; test, dose to target, and retest rather than mega-dosing blindly
