Why baby rats get more sunburn inside their blood
Influence of plasma total antioxidant ability on lipid and protein oxidation products in plasma and erythrocyte ghost obtained from developing and adult rats pretreated with two vitamin K formulations

Giving baby rats vitamin K1 helps protect their blood plasma from damage, but doesn't help their red blood cells. Adult rats don't benefit at all. Baby rats' red blood cells are just more fragile, even when their blood looks healthier.
Surprising Findings
Higher plasma antioxidants in baby rats did NOT protect their red blood cell membranes from lipid damage.
Common belief: more antioxidants = less oxidative damage everywhere. This study shows protection is compartmentalized — plasma and cell membranes are separate battlegrounds.
Practical Takeaways
If you're a parent or caregiver, know that newborns may have unique oxidative stress vulnerabilities — but don’t assume vitamin K1 supplements will protect their cells.

Isolation of lipids from their native food matrix removes endogenous antioxidants and structural protections, increasing susceptibility to oxidative degradation during thermal exposure.
Adult rats don't get any antioxidant boost from vitamin K1, and their blood fats keep getting damaged — unlike baby rats, who do benefit.
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.
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.
Even though baby rats have more antioxidants in their blood, their red blood cells break down fats more easily than adult rats' cells, meaning their blood cells are naturally more fragile.
