What does Rhonda Patrick say about omega-3?

Biochemist (Ph.D.), founder of FoundMyFitness

Rhonda Patrick settles on 2 grams of omega-3 a day - "I like to say two grams a day is really to be safe" - and says that is what she takes. That is the amount she says moves you from a low omega-3 index to a high one, which she treats as a modifiable risk factor you should test rather than guess at.

The figure she lands on, and what she takes

“I like to say two grams a day is really to be safe, but um, two grams a day of omega-3 fatty acids seem to get people from a low to a high omega-3, you know, index level”

The same range, stated the year before

“when we're talking about going from a low omega-3 index to a high omega-3 index, we're not talking about a lot. 1.5 to two grams of a high quality fish oil supplement is easy to do”

What Rhonda actually says

  • The number she lands on is 2 grams a day. She gives the range as 1.5-2 grams and then names 2 grams as the safe figure and her own intake.
  • She frames the dose by outcome, not by habit - 2 grams is what it takes to move someone from a low omega-3 index to a high one, which is where the brain and cardiovascular benefits sit.
  • She argues for testing the omega-3 index rather than guessing, treating it like cholesterol - a modifiable number, not a fixed trait.
  • Her mechanistic angle is the brain's MFSD2A transporter, which takes up DHA in lysophosphatidylcholine form - present in krill oil and salmon roe, not standard fish oil.

Common Questions

How much omega-3 does Rhonda Patrick recommend?

2 grams a day. She gives 1.5-2 grams as the range and then names 2 grams as the figure she uses "to be safe," adding that it is what she takes. She frames it as the amount needed to shift from a low omega-3 index to a high one.

Does Rhonda Patrick prefer krill oil or fish oil?

She notes krill oil's omega-3s are bound to phospholipids rather than triglycerides or ethyl esters, which absorb more efficiently, and that the brain's MFSD2A transporter takes up DHA in a phospholipid form found in krill oil but not standard fish oil.

What omega-3 index does she target?

She treats the omega-3 index as a modifiable cardiovascular risk factor comparable to cholesterol and advocates testing it rather than assuming your intake is adequate.
