How do you get your micronutrients?

I've read quite a bit around and would be interested in giving keto a shot mainly because of increased cognitive and energy benefits than for fat loss.

However, what concerns me a lot is that there are no fruits (I usually make smoothies and juices from fresh fruits and veggies).

So where do the micronutrients and vitamins come from?

Thanks!

edit: thank you for the kind comments!
