8 Diet Coke Alternatives, Reviewed For Quality and Taste

La Croix NiCola LaCola Sparkling Water, 12 Fl Oz (Pack of 8) ($17)

If you're a seltzer lover, this option may be for you. While, in my opinion, it tastes nothing like Diet Coke, La Croix's LaCola is marketed as a naturally essenced sparkling water. It's zero calories with no additives whatsoever. La Croix is known for being caffeine- and gluten-free. I will say, it has a minty scent upon first sniff, unlike the Good & Gather sparkling water on this list, which leans more cherry-smelling.
