Sweet'N Low is a well-known zero-calorie sugar substitute instantly recognizable by its signature pink packets. For over six decades, it has been a staple for millions looking to reduce their sugar intake. However, the product is more than just a single compound. Its composition is a precise blend of active and inactive ingredients designed to provide a sugar-like experience in both taste and texture. Understanding what are the ingredients in Sweet N Low sweetener reveals why this combination works so effectively.
The Core Components of Sweet'N Low
While Sweet'N Low is primarily known for its main sweetener, saccharin, the final product is a blend of four distinct ingredients. These components work in synergy to create a functional and pleasant-to-use product:
- Saccharin: The core artificial sweetener.
- Dextrose: A bulking agent to give the powder substance.
- Cream of Tartar (Potassium Bitartrate): A food additive used to stabilize the mixture.
- Calcium Silicate: An anti-caking agent to ensure a free-flowing powder.
Saccharin: The Zero-Calorie Sweetness Powerhouse
Saccharin is the heart of Sweet'N Low's sweet flavor profile. Discovered in 1879, it was one of the first commercially produced artificial sweeteners. It is 300 to 400 times sweeter than sucrose (table sugar) and provides zero calories. Because of its intense sweetness, only a minuscule amount is needed. Saccharin is heat-stable, making it suitable for use in cooking and baking. However, it can have a slightly bitter or metallic aftertaste, especially in high concentrations. To counter this, it is often blended with other ingredients.
Dextrose: The Essential Bulking Agent
Since saccharin is so potent, it is impractical to sell it alone. Dextrose, a type of sugar derived from corn, is used as a bulking agent to create a product that can be easily measured and packaged. A single packet of Sweet'N Low contains about 0.9 grams of carbohydrates from dextrose, which is less than the 5-calorie threshold the FDA requires for labeling. This gives the product its granular texture and consistency, making it a familiar alternative to sugar for stirring into beverages or sprinkling on food.
Cream of Tartar and Calcium Silicate: The Supporting Ingredients
Beyond saccharin and dextrose, Sweet'N Low relies on two other ingredients to perfect its formula:
- Cream of Tartar (Potassium Bitartrate): This acidic salt, a byproduct of winemaking, serves a dual purpose. It acts as a stabilizer and helps to mask the potential metallic aftertaste of saccharin, creating a more balanced flavor profile.
- Calcium Silicate: This substance is used as an anti-caking agent. It prevents the finely powdered ingredients from clumping together, ensuring that the product pours smoothly from the packet and dissolves easily in liquids, both hot and cold.
How Sweet'N Low Compares to Other Popular Sweeteners
Sweet'N Low's composition differs significantly from other popular sugar substitutes on the market. Here's a quick comparison:
| Feature | Sweet'N Low (Saccharin) | Splenda (Sucralose) | Equal (Aspartame) | Stevia (Rebaudioside A) |
|---|---|---|---|---|
| Sweetness Intensity | ~300-400x sweeter than sugar | ~600x sweeter than sugar | ~200x sweeter than sugar | ~200x sweeter than sugar |
| Caloric Content | 0 calories per serving (<4 per packet) | 0 calories per serving (<2% of sugar equivalent) | 0 calories per serving (<2% of sugar equivalent) | 0 calories per serving |
| Bulking Agent | Dextrose | Dextrose and maltodextrin | Dextrose | Erythritol or dextrose |
| Heat Stable | Yes, stable for baking and cooking | Yes, stable for baking and cooking | No, loses sweetness with heat | Yes, stable for baking |
| Aftertaste | Can have a metallic aftertaste | Generally minimal aftertaste | Generally clean taste | Can have a licorice-like aftertaste |
The Controversial History and Safety of Saccharin
In the 1970s, saccharin faced public scrutiny following studies in laboratory rats that linked high doses of the sweetener to bladder cancer. This led to mandatory warning labels on products containing saccharin. However, later research indicated that the mechanism causing tumors in rats was not relevant to humans, and observational human studies showed no link between saccharin and cancer. The FDA removed saccharin from its list of potential carcinogens in 2000, and the warning labels were dropped. Reputable health organizations, including the FDA and the World Health Organization (WHO), now deem saccharin safe for human consumption within established acceptable daily intake (ADI) levels. Some newer research is exploring potential effects on gut microbiota, but large-scale studies are still needed.

Conclusion
In summary, the ingredients in Sweet'N Low sweetener are saccharin, dextrose, cream of tartar, and calcium silicate. Saccharin provides the intense, zero-calorie sweetness, while dextrose adds bulk. The cream of tartar and calcium silicate function as stabilizing and anti-caking agents, respectively, perfecting the product's texture and flavor profile. Despite its past controversy, saccharin is considered safe for consumption by major health authorities. This carefully balanced blend of ingredients ensures that Sweet'N Low remains a convenient and effective sugar substitute for many people.
