Which store sells the most food supplements?

It's impossible to definitively say which store sells the most food supplements globally. There is no public data tracking this specific metric across all retailers.

However, here are some of the leading contenders for the most food supplement sales:

* Amazon: This online retailer has a massive selection of food supplements and benefits from its vast customer base.

* Walmart: This retail giant has a strong presence in physical stores and online, offering a wide range of food supplements at competitive prices.

* Costco: Known for its bulk pricing, Costco offers food supplements at a lower cost, attracting customers who purchase in large quantities.

* GNC: This specialized chain focuses exclusively on health and wellness products, including food supplements, making it a significant player in the industry.

* CVS and Walgreens: These drugstore chains carry a wide selection of food supplements and are convenient for many shoppers.

* Specialty health food stores: Stores like Whole Foods Market, Trader Joe's, and Sprouts Farmers Market also sell a substantial amount of food supplements.

It's important to note that market share can fluctuate significantly depending on the region, product category, and year. Additionally, the rise of direct-to-consumer brands and online marketplaces further complicates the picture.
