Yes it's okay to eat 6 eggs per day if you want too as long as you do not have too high of cholesterol as the eggs when eaten too much could cause your cholesterol levels to rise.
But 6 eggs really shouldn't cause your cholesterol levels to go up too much but do keep check on your cholesterol levels when eating 6 eggs per day if you do suffer from high cholesterol.
But if you do not have problems with high cholesterol then eating 6 eggs per day is just fine.
Sometimes I eat 6 and even 10 eggs on some days but usually I just eat a couple eggs in the morning with some bacon or other breakfast.
I couldn't eat nothing but eggs everyday but if I had to I guess I could.
Eggs are healthy so eating 6 eggs per day should benefit your health as long as you do not have the high cholesterol.
