What Is Reb-M? The Plant-Extracted Sweetener in ELITE
Reb-M (rebaudioside M) is the cleanest-tasting sweetener in the stevia leaf. How it's extracted, why it doesn't taste like old stevia, and why ELITE uses it.
Key takeaways
- Reb-M (rebaudioside M) is a sweetener extracted from the stevia leaf — plant-derived, not artificial.
- It's the cleanest-tasting glycoside in the leaf, without the bitter aftertaste of older stevia extracts.
- ELITE is sweetened only with plant-extracted Reb-M — no monk fruit, no sucralose, no sugar alcohols.
Reb-M is the reason a zero-sugar energy drink can taste like a treat instead of a compromise. It's the sweetener in every can of ELITE — here's what it actually is.
Where Reb-M comes from
The leaves of Stevia rebaudiana contain a family of sweet compounds called steviol glycosides. The most abundant is stevioside — the source of the bitter, licorice-like aftertaste people associate with old stevia products. Rebaudioside M is a different glycoside in the same leaf: sweeter, cleaner, and remarkably close to sugar in taste. ELITE's Reb-M is extracted directly from the stevia plant — not produced by fermentation.
Why it tastes better than old stevia
Early stevia sweeteners were mostly stevioside and Reb-A, which activate bitter taste receptors alongside the sweet ones. Reb-M has a much cleaner profile, which is why it can sweeten a drink on its own without a blend of masking agents.
Reb-M vs the sweeteners it replaces
| Reb-M (ELITE) | Common zero-sugar sweeteners | |
|---|---|---|
| Origin | Extracted from the stevia leaf | Sucralose and aspartame are synthesized; erythritol is a sugar alcohol |
| Calories | Zero | Zero |
| Aftertaste | Clean, sugar-like | Sucralose: sweet/metallic; erythritol: cooling |
| Blood sugar | No impact | No impact for most; erythritol is absorbed |
Is it safe?
Steviol glycosides, including Reb-M, hold GRAS (Generally Recognized as Safe) status with the FDA — a safety conclusion based on reviewed scientific data, not a formal product approval — and are permitted in the EU following EFSA evaluation, with an acceptable daily intake set well above what any realistic diet reaches. As with any sweetener, the sensible frame is the whole diet, not a single ingredient.
Why ELITE uses it
Every ELITE can is 0 g sugar and 10 calories, sweetened only with plant-extracted Reb-M. No sucralose, no aspartame, no erythritol, no monk fruit — one clean, plant-derived sweetener across all three flavors.

Frequently asked questions
Is Reb-M an artificial sweetener?
No. Reb-M is a steviol glycoside extracted from the stevia leaf — a plant extract, not a synthesized compound like sucralose or aspartame.
Does Reb-M taste like stevia?
Not the way older stevia extracts do. Reb-M is the sweetest, cleanest-tasting glycoside in the leaf, without the bitter licorice note of stevioside or Reb-A.
Does ELITE use monk fruit?
No. ELITE is sweetened only with plant-extracted Reb-M — no monk fruit, no sucralose, no sugar alcohols.
