when to add nutrient to starter

I am making my first starter and was wondering about adding yeast nutrient. During wort boiling or when I pitch the yeast. I was thinking that the nutrient should be boiled just like the wort so it is sterilized but, would boiling kill any helpful nutrients? If I add it to the cooled wort am I likely to add contaminants that haven’t been sterilized?
The stuff is Fermax Yeast Nutrient by Crosby and Baker, Ltd. I bought at local homebrew supplier.
Thanks in advance.

Youll want to boil the stuff for 15 minutes with the rest of your starter wort!

+1.

That’s what I’ve always done. Yeast haven’t complained.

I pressure can extra wort to use for starters.  Before canning, I always add yeast nutrient.  Pressure canning boils the heck out of it and the nutrient still makes a noticable difference so it would seem the temps don’t hurt it.

Thanks for the info. i will put the nutrient in with the extract for boiling.
