Adult rats don't get any antioxidant boost from vitamin K1, and their blood fats keep getting damaged — unlike baby rats, who do benefit.

The study found that vitamin K1 and menadione boost antioxidant levels in baby rats but not in adult rats, and in adults, more fat damage occurs—exactly what the claim says.

Similar Assertions

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.

Vitamin K1 helps protect fats in the blood of baby rats, but it doesn't help protect the fats inside their red blood cells — even though the blood has more antioxidants overall.

78%

Even though vitamin K1 helps protect fats in baby rats' blood, it doesn't help protect the proteins in their red blood cells from damage.

When rats didn't get any vitamin E in their food, their bodies showed more signs of fat damage, no matter what kind of fats they ate.
