multivitamins and cod liver oil?

Are they safe to be eaten as two separate supplements but consumed together daily
I understand both include their own particular dose of vitamin A and D,
I don't want to overdose on having too much of them vitamins in my body?

Yes they are safe but the Cod liver oil I would do 4 days out of a week not 7 because the amounts can sometimes make you weak instead of energetic but is good for you
