Are the protein supplements necessary for bodybuilding

Im not a native speaker, so I want it to be simple (not complex) but also it should be written academically. It must have coherence. Hint, I am in my first year at the university. Also, no plagiarism.
This assignment for non-major chemistry course. My topic is to investigate the question, a?are the protein supplements necessary for bodybuilding?a?. The report should have a clear thesis statement. Do not use books as a reference. You just can use articles that are reliable. there is no maximum nor minimum number of sources.

**** the instructor asked for a report but I couldnt see it under the paper subject list. (report)
