Protein Bars Without Artificial Sweeteners
These bars contain none of the four main artificial sweeteners: sucralose, acesulfame potassium (Ace-K), aspartame or saccharin, verified against the full ingredient statement. Plant derived and rare sugar sweeteners (stevia, monk fruit, allulose) are allowed, as is regular sugar. Ranked by protein per 100 calories.

What “no artificial sweeteners” means on this page
A bar qualifies only when its captured ingredient list contains none of sucralose, acesulfame potassium, aspartame or saccharin. Stevia, monk fruit and allulose are naturally derived and do not disqualify a bar. Note that many of these bars use real sugar instead, so check the sugar column, and check the low sugar ranking too if you want both.
How this ranking works
- Every nutrition value is transcribed from the manufacturer’s published nutrition label and verified by hand, with no third party food databases.
- Product lines are ranked, not individual flavours, so one product’s 20 flavours can’t fill the list. Each entry shows its best scoring flavour.
- A maximum of two lines per brand keeps the list diverse.
- Labels that don’t state sugar or fiber are treated as unknown (never as zero) and are excluded from sugar and fiber rankings.
- Want to hit a daily protein target? The Protein Pal app lets you scan any label and track your protein day by day.
Frequently asked questions
- Are stevia and monk fruit artificial sweeteners?
- No. Stevia (steviol glycosides) and monk fruit extract are derived from plants, and allulose is a rare sugar found naturally in figs and raisins. Regulators and most consumer usage treat “artificial sweeteners” as the synthetic set: sucralose, acesulfame potassium, aspartame and saccharin, which is the definition this page uses.
- Do bars without artificial sweeteners have more sugar?
- Often, yes: removing sucralose usually means either real sugar or sugar alcohols take its place. The table above shows each bar’s sugar per serving so you can weigh it up; several bars manage both low sugar and no artificial sweeteners.
