What is aspartame?

Aspartame is a low-calorie sugar substitute. It can be used in place of sugar to give you a reduced- or no-sugar alternative. It is 200 times sweeter than sugar, so only a little is needed for the same sweet taste.


Do you have products containing use aspartame?

Yes. We use aspartame as a sweetener in some of our drinks to help us keep the great tastes people love, but with fewer or no calories.

We use aspartame in Diet Coke, Coke Zero Sugar, Fanta Zero, Fresca and some of your other favorites.

Why do you use aspartame?

While sugar in moderation is fine, too much sugar isn’t good for anyone. That’s why we make reduced- and no-sugar versions of many of the drinks you love. We want to give you great-tasting choices with fewer or no calories. Aspartame helps us do that.

Is aspartame safe?

Yes. Aspartame is safe. It is one of the most thoroughly researched ingredients in the world.

Science and health professional organizations have affirmed sugar substitutes, like aspartame, are safe. So have food safety authorities, like the FDA.

However, if you have the rare hereditary disorder phenylketonuria (PKU), you should strictly limit your intake of phenylalanine. This is a common amino acid found in aspartame. If we use aspartame, we say on our bottles and cans that there is phenylalanine so please check closely.

Have questions about PKU or your diet? Please talk to your doctor.

There is phenylalanine in Diet Coke. There is also phenylalanine in Coke Zero Sugar. If you have the rare hereditary disorder PKU, you should strictly limit your intake of phenylalanine.

What is the acceptable daily intake (ADI) for aspartame?

ADI is set by the FDA. This is how much you can safely have each day. The ADI for aspartame is like a 132-pound adult having 75 tabletop packets. That’s about sixteen 12-oz cans of diet soda a day.
