Giving baby rats vitamin K1 helps their blood fight off damaging molecules called free radicals, and this helps keep their fats from breaking down too much.

2004 Dec

In baby rats, giving more vitamin K1 made their blood better at fighting damage from free radicals, and this also reduced harmful fat damage in their blood—exactly what the claim says.
