Most of the US FDA rules state that you use the common or usual name for ingredients. 21 CFR 101.36 is Nutrition labeling of dietary supplements. The website to find this is https://www.ecfr.gov...CFR?page=browse
Part (d)(1) of 21 CFR 101.36 says:
"(1) Source ingredients shall be identified in accordance with §101.4 (i.e., shall be listed by common or usual name, and the listing of botanicals shall specify the part of the plant from which the ingredient is derived) regardless of whether they are listed in an ingredient statement or in the nutrition label."
I don't see anything about brand names in parenthesis so I'm not sure if that's ok or not. Maybe try looking at FDA warning letters and see if there is anything about brand names for ingredients. Reading through the warning letters is a good way to learn how the FDA interprets labeling and issues.
Hope this helps!
