Which NAICS to choose

Hi there! I’m opening an electrolyte powder FBA business, and was a bit torn on which NAICS to choose. I know that the online commerce NAICS (454110) is pretty common for most Amazon Sellers, but I wasn’t sure if mine would be difference since I’m selling electrolyte powder, which falls a bit more under the nutrition/supplement category.

For context, the NAICS for vitamins and supplements is 456191. Any thoughts would be appreciated!
