Which of these 2 items is better for my keto diet

Hi All, this is my first post.

Am almost one week in and deciding what to mix with my vodka, which I only have a couple times a week.

Both are store bought lime juice,

one says per 100g =carbs 6.2g and sugar .5g

one says per 100g =carbs 7.4g and sugar 7.1g

Still trying to get my head around this stuff.

Thanks

Ian
