Where Can You Find Saccharin?
Saccharin is used as a table sweetener sold under the brand names Sweet ‘N Low, Necta Sweet, and Sweet Twin. It’s found in a range of diet foods and drinks, baked goods, jams, jelly, canned fruit, candy, dessert toppings, and chewing gum.
Saccharin is in plenty of artificially sweetened drinks, but the FDA restricts the amount to no more than 12mg per fluid ounce. In the European Union, you can identify saccharin on food product labels as E954.
You can find saccharin in granule or liquid form. The sweetness of one serving is comparable to two teaspoons of sugar.
When saccharin was banned in the 1970s, lots of diet drink manufacturers switched to aspartame and continue to use aspartame today.
You can also find saccharin in non-food items like mouthwash, toothpaste, medicines, and pharmaceuticals.
What About Blood Sugar?
Saccharin isn’t metabolized by the body and doesn’t affect blood sugar the same way refined sugar does. While there aren’t many studies on the effects of this sweetener alone on blood sugar levels, several studies examined the effects of other artificial sweeteners.
For example, one study of 128 people with type 2 diabetes revealed consuming the artificial sweetener Splenda (sucralose) didn’t affect blood sugar levels . The same result occurred in studies of other artificial sweeteners like aspartame  .
Most evidence suggests artificial sweeteners don’t significantly affect blood sugar levels in diabetics or healthy people . It’s unlikely saccharin affects long-term blood sugar control in those with diabetes or healthy people, but every individual is different, so you might want to check your blood sugar levels after consuming saccharin to check your response.
How Much Should You Eat?
The FDA states adults and children can consume up to 2.3mg of saccharin per pound (5mg per kilogram) of body weight without risk.
Should You Include Saccharin in Your Ketogenic Diet?
