What does Mark Hyman say about omega-3?

Functional-medicine physician and author

Mark Hyman lists omega-3 alongside vitamin D and magnesium as a foundational supplement almost everyone needs. He says 90% of Americans miss the recommended intake, and calls one serving of fatty fish twice a week "a bare minimum" — naming sardines, herring, mackerel, anchovies and wild salmon rather than large fish.

On the record

“90% of Americans are not meeting the recommendations for omega-3 intake which is one serving of fatty fish at least two times a week and I think that's a bare minimum”

What Mark actually says

• His framing is deficiency-first — he puts omega-3 among the most prevalent deficiencies alongside iron, vitamin D and magnesium.
• Twice-weekly fatty fish is the floor, not the target. He is explicit that he considers it a bare minimum rather than an optimum.
• He favours small fatty fish (sardines, herring, mackerel, anchovies) — which also sidesteps the mercury load that comes with larger predatory fish.

Common Questions

How much omega-3 does Mark Hyman recommend?

He anchors on food first — at least two servings of fatty fish a week, which he calls a bare minimum — and lists omega-3 among the foundational supplements he thinks most people should take alongside a multivitamin, vitamin D3, magnesium and probiotics.

Which fish does Hyman recommend?

Small fatty fish: sardines, herring, mackerel, anchovies, and some wild salmon. The size matters — smaller fish carry a lower mercury burden than large predatory species.

Why does Hyman think omega-3 deficiency is so common?

He attributes it to the shift away from the wild and sea-based foods humans historically ate, combined with a sharp drop in wild fish intake on a modern industrial diet.
