Answer: Jolly Ranchers Sugar-Free are not keto due to their non-keto sweeteners.
When it comes to keto-friendly hard candies, the options are pretty thin. Virtually every low-carb or low-sugar candy achieves its low carb count through non-keto sweeteners, like maltitol or sorbitol.
One notable exception is Dr. John's Healthy Sweets Sugar-Free Fruit Hard Candy. Dr. John's uses only keto-friendly sweeteners: erythritol, xylitol, and stevia. Best of all, they're only 1 g of net carbs per serving.
Venturing a bit outside candies, dark chocolate is a classic keto sweet. Varieties that are 80% cacao or higher tend to run between 4 to 6 g of net carbs per serving. Specialty brands like Lily's Chocolate sweeten their chocolate with erythritol, making it even easier to eat on keto.
