I have a sentence that contains the phrase

We support products of different manufacturers [...]

Is the use of 'of' correct there? A coworker said I should use 'by' and I also can think of 'from' as a possible word.

When do I use which?

    The most idiomatic preposition would be "from". You might also find our sister site, ELL a useful resource for questions like this.

  • Thank you Dan. I wasn't aware that there is another SE about english language questions.

  • No problem Jens. Yeah, we're trying to work on increasing the visibility of ELL; the good news is it's about to "graduate" out of (2 year long!) beta.

If it must be just one word, then "from" is best.

"By" would only work if you change it to *we support products made by different manufacturers.

"Of" in this context sounds unnatural at least in AmE. Part of this is that "of" in that particular position (but not in this sentence) could reflect either a subjective or an objective genitive. Meaning it could mean either We support the products that come from different manufacturers or *We support the products that belong to different manufacturers.
