A red pigment found in shrimp and salmon (astaxanthin) helped male mice live 12% longer when given to middle-aged mice at a high dose, which was the biggest lifespan boost seen in a major government testing program in over a decade.

Astaxanthin and meclizine extend lifespan in UM-HET3 male mice; fisetin, SG1002 (hydrogen sulfide donor), dimethyl fumarate, mycophenolic acid, and 4-phenylbutyrate do not significantly affect lifespan in either sex at the doses and schedules used

The study tested astaxanthin in mice and found it extended male mouse lifespan by 12%, matching the claim's main finding about median lifespan extension, though the actual dose used was about half of what the claim stated.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Scientists gave a red pigment called astaxanthin (found in salmon and shrimp) to older mice and found they lived about 12% longer than mice that didn't get it - that's like a person living an extra 8-10 years.

Two supplements—astaxanthin and meclizine—helped male mice live longer, but female mice didn't get the same benefit when given the same amounts.
