which one is correct? need help plese

a)some people were not provided with either milk or juice
b)some people were provided neither milk or juice

thanks

a) some people were not provided either milk or juice
b) some people were provided neither milk nor juice.

“Some people were not provided with either milk or juice” is OK.
“Some people were provided with neither milk nor juice” is OK.

The same sentences without “with” are intelligible but inferior in my opinion.
