starting dim supplements any advice on combining with vitamins

i just bought the berkeley formula dim supplement and want to start taking it for hormone balance and immune support. i plan to combine it with a daily multivitamin and vitamin d since my levels are low from little sun exposure.

i am 35 and deal with stress and irregular cycles so hoping this helps long term. how do you stack dim with other vitamins without issues and what dosage timing works best? any side effects to watch for when starting?

thanks in advance for any tips.
