The Core Ingredients of Pepsi Zero Sugar
When you pick up a can of Pepsi Zero Sugar, you are holding a precisely engineered blend of ingredients designed to mimic the taste of regular cola without the sugar. The primary components can be broken down into five main categories: the base, artificial sweeteners, flavoring agents, coloring, and preservatives.
The Base and Acids
The foundation of Pepsi Zero Sugar is simple carbonated water. It provides the effervescent quality that defines all sodas. However, its other base components play a more functional role. Phosphoric acid, a common food additive, serves two key purposes: it provides a sharp, tangy taste and acts as a preservative to prevent the growth of mold and bacteria. Citric acid also contributes to the tangy profile and is another preservative.
The Artificial Sweeteners: Aspartame and Acesulfame Potassium
To achieve a sweet taste without using sugar, Pepsi Zero uses a combination of artificial sweeteners. This is a key differentiator from other diet drinks. Aspartame is a popular zero-calorie sweetener, while Acesulfame Potassium (Ace-K) is another non-nutritive sweetener. The combination of these two, in varying ratios compared to other products like Diet Pepsi, is what gives Pepsi Zero its specific flavor profile, which some describe as a bolder, more robust taste closer to the original full-sugar Pepsi.
Flavoring, Coloring, and Preservatives
The signature dark color of Pepsi Zero comes from caramel color, specifically caramel E150d in some international versions. The cola taste itself is created by a blend of natural flavors, the exact composition of which is a proprietary secret. Caffeine is added for a stimulating effect, and its quantity can vary by region. For example, some North American versions contain a specific amount, which was reduced during a 2023 reformulation. Other additives include potassium benzoate, used to preserve freshness and prevent spoilage, and calcium disodium EDTA, which protects the flavor.
Pepsi Zero Sugar vs. Other Variants: A Comparison
Understanding what's inside Pepsi Zero is easier when you compare it to other similar products. Here's a look at how it stacks up against its diet counterpart, Diet Pepsi, and its full-sugar origin, regular Pepsi.
| Feature | Pepsi Zero Sugar | Diet Pepsi (US) | Regular Pepsi |
|---|---|---|---|
| Sweeteners | Aspartame & Acesulfame Potassium | Aspartame only | High-fructose corn syrup / Sugar |
| Calories | Zero (0 per 12 oz can) | Zero (0 per 12 oz can) | ~150 (per 12 oz can) |
| Sugar | Zero | Zero | ~41 grams (per 12 oz can) |
| Taste Profile | Bolder, more robust cola flavor | Lighter, crisper, and sometimes less intense | Classic, full-bodied sugary cola |
| Caffeine (US) | Higher content (38-69 mg per 12 oz) | Lower content (36-37 mg per 12 oz) | Moderate content (38 mg per 12 oz) |
| Other Additives | Calcium disodium EDTA included | Calcium disodium EDTA not included | N/A |
Potential Health Considerations
While Pepsi Zero Sugar offers a calorie-free alternative to sugary drinks, the use of artificial sweeteners and other additives has prompted health discussions. Studies have explored potential links between artificial sweetener consumption and an increased risk of issues like metabolic syndrome, Type 2 diabetes, and certain cardiovascular problems. The World Health Organization's International Agency for Research on Cancer has also classified aspartame as "possibly carcinogenic to humans," though this is based on limited evidence and requires very high consumption levels to potentially pose a risk.
Another concern is the effect of the high acidity, primarily from phosphoric acid, on dental health. The acids in diet sodas can erode tooth enamel over time, regardless of sugar content. For individuals managing their intake of certain chemicals, reviewing the complete ingredient list is always recommended.

Conclusion: More Than Just 'Zero'
Ultimately, what does zero Pepsi contain is a mix of carbonated water, artificial sweeteners (aspartame and Ace-K), flavorings, coloring, and several preservatives. It is a carefully formulated product designed to deliver maximum cola flavor with zero sugar and zero calories. However, its ingredient list differs from other diet and full-sugar variants, offering a distinct taste and caffeine level. While the health community's opinions on artificial sweeteners are mixed and studies are ongoing, Pepsi Zero Sugar remains a popular choice for those seeking a sugar-free soda. It is always wise to consume such products in moderation and stay informed about their contents to make the best decisions for your dietary needs.
