time.Now().UnixNano() Isn't fast enough of a random seed

I'm currently generating random data in Go, and I'm having an issue with generating random numbers in sequence with Go's math/rand package. For example, if I need to generate a list of random integers, even with my function:

func random(min, max int) int {
rand.Seed(time.Now().UTC().UnixNano())
return rand.Intn(max - min) + min
}

Consecutive numbers returned by random(0,100) will still always be equivalent (I guess because they are randomly produced at the same time in nano seconds?) Is there any way around this?
