Correct. When choosing quick remedies for low blood sugar think of something that will dissolve quickly. Options like these are commonly used:
glucose tablets (available at most pharmacies) [3 or 4 tablets ~15g carbs]
orange juice (apple juice ) [roughly half a cup ~ 15g carbs]
soda [roughly half a cup ~ 15g carbs]
honey (1 tablespoon ~15g carbs]
half a banana [~ 15 grams]
Some people even use hard candies [ just make sure you only eat 15 grams of carb of them!]
You never know when a low can strike!
Being prepared and having rescue treats on hand at all times is a great idea!
