Gummies usually carry some sugar or sweetener, which matters on a low-carb diet.
The page does not give sugar, carbohydrate or calorie figures that we could use. The ingredient list includes raw honey extract, which is a named ingredient, but that says nothing about the total sugar in the gummy base.
Only the Supplement Facts panel can tell you.
Ask the seller for an image of the panel before you buy, or read it when the bottle arrives. Check total carbohydrates, added sugars and any sugar alcohols. If your daily carb limit is tight, calculate the gummy as part of it. If keto is part of a medical plan, check with your doctor or dietitian.
