Trying Protein Powders - Are they Safe?

I'm trying to make the right food choices on this weight loss journey.

I'm not getting enough protein (close to Vegan diet) and am looking at some protein powders.

I've tried the Sunwarrior brand but am skeptical about all things processed.

Anyone have any knowledge or advice?

Edemame is becoming a staple part of my plan!

Thank you!
