I run and do strength training. I think the consensus is that it's not that beneficial for running. You're going to gain a bit of weight which presumably is going to make you slower.

If you were a competitive runner then you'd probably want to cycle it so that you get the strength training benefit but also optimize for your races.

I take it. I did a 10k race and stopped for two weeks. I'm also not super consistent but I try to take about 5-10g a day.

In terms of optimizing overall health I would say take it + running + strength training is a good combination. The effects are not huge and vary person to person.
