# Diabetes How Much Insulin To Take?

## How do I calculate how much insulin to take?

Step 1: Calculate an insulin dose for food: Divide the total grams of carb by your insulin-to-carb ratio. Example Let’s say you plan to eat 45 grams of carbohydrate and your insulin-to-carb ratio is 1 unit of insulin for every 15 grams of carbohydrate eaten. To figure out how much insulin to give, divide 45 by 15.
