Is store-bought kimchi healthy?

I'm curious, could you elaborate on the health benefits or potential drawbacks of store-bought kimchi? I've heard mixed reviews, some saying it's a great source of probiotics, while others claim the preservatives and additives may detract from its nutritional value. As someone interested in maintaining a healthy diet, I'd like to know if store-bought kimchi is a wise choice, or if homemade kimchi would be a more nutritious option. Can you provide any insights on this topic?
