Unpacking the “Puff Bar” Misconception
The phrase "Puff Bar" is commonly associated with disposable electronic cigarettes, which vaporize a liquid containing flavorings and, typically, nicotine. However, Built Brands also sells a line of protein bars called "Built Puffs". The critical difference is that one product is ingested, and the other is inhaled, a distinction with profound implications for the ingredients used and their potential health effects. This article clarifies the sweetening agents found in both products to provide a clear, evidence-based answer to the question.
Sweeteners in Built Puff Protein Bars
Built Puff protein bars utilize a combination of standard sugar and sugar alcohols to achieve their signature flavor. This distinguishes them from some other "low sugar" products that rely solely on non-nutritive sweeteners. Key sweeteners and related ingredients in Built Puffs include:
- Sugar: The dark chocolate coating on Built Bars, including the Puffs, contains real sugar. For instance, a brownie batter puff may have 6 grams of added sugar.
- Erythritol: This is a sugar alcohol commonly used in both Built Bars and Built Puffs. It is fermented from natural sugars and has fewer calories than sugar, making it a popular choice for lower-calorie products. While generally well-tolerated, some individuals with sensitive digestive systems may experience discomfort.
- Glycerin: A sweet, syrupy liquid, glycerin is used to add sweetness and retain moisture, which contributes to the soft texture of the bars.
- Cultured Dextrose: This is a sugar derivative also used as an ingredient.
In essence, Built Puffs contain a mix of different types of sweeteners. It would be inaccurate to say they use only "fake sugar," as they contain real sugar in the chocolate coating, alongside sugar alcohols and other sweetening agents.
Sweeteners in Disposable Vapes (Puff Bars)
Disposable vapes, often generically called "Puff Bars," contain a liquid that is heated to create a vapor for inhalation. Due to the heating process, traditional sugars like sucrose are avoided because they would caramelize and burn, damaging the device and producing potentially harmful chemicals when inhaled. Instead, vape manufacturers rely on high-potency artificial sweeteners.
Common Sweeteners in Vapes:
- Sucralose: As the most common artificial sweetener in e-liquids, sucralose provides a sugar-like taste. However, when heated, sucralose can break down into potentially toxic chlorinated compounds and aldehydes. Research has shown that vaping sucralose can even cause the heating coil to corrode, releasing heavy metals into the vapor.
- Neotame: A 2025 Yale study found that the potent artificial sweetener neotame, which is thousands of times sweeter than sugar, is prevalent in many disposable vapes. Concerns were raised because neotame's inhalation toxicity has not been thoroughly tested, and it is often not listed on the product label.
- Ethyl Maltol: This flavoring agent has a sweet, cotton-candy-like taste and is also used to enhance sweetness in some e-liquids. Unlike sucralose, it does not seem to cause rapid coil degradation.
- Vegetable Glycerin (VG): One of the primary base ingredients of e-liquid, VG has a natural, mild sweetness that contributes to the overall flavor.
Health and Regulatory Implications
The fundamental difference between ingesting food-grade sweeteners and inhaling vaporized additives is critical. Many compounds considered safe for consumption via the digestive system have not been approved or tested for inhalation. This difference is at the core of regulatory efforts and health warnings related to flavored tobacco and vaping products. For instance, the US Flavor & Extract Manufacturers Association has explicitly stated that its safety assessments for flavors apply only to human food, not to inhalation products. The discovery of unlabeled, un-tested sweeteners like neotame in disposable vapes only amplifies these concerns.
Comparison: Built Puffs vs. Disposable Vapes
| Feature | Built Puff Protein Bars | Disposable Vapes (Puff Bars) |
|---|---|---|
| Product Type | Edible protein bar | Inhalable aerosol device |
| Primary Function | High-protein snack | Recreational/Nicotine delivery |
| Primary Sweeteners | Sugar, Erythritol, Glycerin, Cultured Dextrose | Sucralose, Neotame, Ethyl Maltol, Vegetable Glycerin |
| Real Sugar Content? | Yes, in the chocolate coating | No, traditional sugars are not used |
| Sweetener Stability | Sweeteners are ingested and processed by the body | Artificial sweeteners can break down when heated |
| Inhalation Safety | Not applicable | Sweeteners not approved for inhalation |
| Label Transparency | Ingredients are listed on packaging | Sweeteners like neotame often not disclosed |
The Takeaway on Sweeteners
The presence and type of sweeteners depend entirely on the product in question. Built Puff protein bars use a combination of natural sugar and sugar alcohols, which are processed by the digestive system. Inhaled disposable vapes, or "Puff Bars," contain high-potency artificial sweeteners that are not processed through the digestive system and whose safety upon inhalation is largely unknown. This distinction is critical for anyone concerned about their health or the ingredients they consume or inhale.
Conclusion
In summary, the question "Do built puff bars have fake sugar?" has two different answers depending on the product referenced. Built Puff protein bars contain a mix of natural sugar and sugar alcohols like erythritol and glycerin. In contrast, disposable vaping products, often colloquially called "Puff Bars," use a variety of potent artificial sweeteners, most notably sucralose and neotame, instead of real sugar, because real sugar cannot be safely heated and inhaled. Recent research has raised significant concerns about the safety of inhaling these artificial sweeteners, highlighting the need for greater transparency and regulation. Consumers should always check product labels and be aware of the ingredients in what they are consuming or inhaling.

Additional Considerations for Consumers
- Digestive Sensitivity: While erythritol in Built Puffs is generally well-tolerated, sugar alcohols can cause digestive issues in some individuals.
- Inhalation Risks: The safety profile of inhaled sweeteners like sucralose and neotame is not well-established, with research indicating potential for toxic byproducts upon heating.
- Label Discrepancies: Be aware that ingredients in disposable vapes, particularly potent sweeteners like neotame, may not be disclosed on the packaging.
By understanding the different roles and risks of sweeteners in each product, consumers can make more informed choices about their health and wellness.
