I've considered eating algae as an alternative source of DHA with less risk of microplastic contamination, but I've had a hard time finding definitive evidence of what types of algae contain significant levels of DHA.

Algal supplements might be the easiest way of doing that. (That's what I currently do.)

And from what I understand it's mostly micro-algae with EPA/DHA.
