Does Stevia Spike Insulin?
Summary
Stevia itself does not spike insulin and is considered a safe, natural sweetener for most people, including diabetics and pre-diabetics. The main concern is not stevia itself, but common filler ingredients — particularly maltodextrin — found in many stevia products. With decades of clinical observation, the author reports no negative outcomes from stevia use across tens of thousands of clients.
Key Takeaways
- Pure stevia does not spike insulin — the risk comes from additives, not the herb itself
- Always read labels: avoid stevia products containing maltodextrin or dextrin
- Maltodextrin has roughly double the glycemic index of regular sugar, making it one of the worst ingredients to consume
- Stevia is 300 times sweeter than sugar, so very small amounts are needed
- Animal studies show stevia may actually improve blood sugar levels
- Human studies on stevia are currently limited, but clinical experience supports its safety
- Stevia is recommended for pre-diabetics, diabetics, and people trying to lose weight
- Liquid stevia in carbonated water is one practical, clean way to use it

The Real Problem: Hidden Additives
Pure stevia is derived from an herb and is naturally calorie-free. However, many commercial stevia products use maltodextrin or dextrin as bulking or anti-caking agents. These are processed starches with a very high glycemic index — maltodextrin ranks higher than regular table sugar — meaning they can significantly raise blood glucose and trigger an insulin response.
Practical rule: If a stevia product lists maltodextrin or dextrin on the label, avoid it entirely. This applies to any food product, not just sweeteners.
What the Evidence Shows
- Animal studies have demonstrated improvements in blood sugar regulation with stevia use
- Human clinical studies remain limited at this time
- Observational clinical experience (30+ years, tens of thousands of clients): no insulin or blood sugar problems observed from pure stevia use across populations including pre-diabetics and type 2 diabetics
Who Can Use Stevia Safely
According to the video, stevia is appropriate for:
- People managing insulin resistance or type 2 diabetes
- Pre-diabetics monitoring blood glucose
- Anyone following a low-carb diet or working toward weight loss
Recommended Format
Liquid stevia is highlighted as a preferred format — it typically contains fewer additives than powdered or granulated versions — and pairs well with carbonated water as a sugar-free beverage option.
