Stevia Health Benefits & Safety -- stevia leaf spoonful of stevia


Stevia (Stevia rebaudiana) is generally promoted as a natural, non-caloric sweetener and an alternative to other sweeteners such as sucralose (Splenda) and aspartame (Nutrasweet, Equal). It is sometimes promoted for lowering blood sugar, lowering blood pressure, and even as a treatment for Lyme disease, but the evidence behind these claims is weak, and be aware that some people may experience side effects — although it is generally safe — as explained in the full answer >>

Being extremely sensitive to alcohol sugars (sorbitol, mannitol, erithrytol, xylitol etc) that cause me to have almost immediate diarrhea, I turned to stevia because I do not want to put chemicals in my body. Well, it turns out that I can not stand the taste of stevia in ANY product. Makes me gag. So I stopped using any processed sugar and use a small amount of raw honey and maple syrup instead. My A1c dropped to 5 in just a couple of months and has stayed there. Turns out I need no artificial sweetners, no alcohol sugars, and no natural but not common sweetners of any kind. Trees and bees. That's the ticket.

I get horrific migraines from stevia within just a few minutes of ingestion.

I have no financial interest in any sweeteners, and I thought Stevia was great and used it for about six months until I noted my gait became different, odd. I immediately went online and found others who report similar side effects, most mentioning it causing leg problems. I stopped using it and still have a slight issue with my gait, but it is better. Stevia is not completely safe for everyone.

I was taking large quantities for Lyme disease and after 17 days I noticed pain in one of my legs. I am very grateful for seeing this post and have stopped using it. Thanks for sharing.

I have been using stevia for about 10 years to sweeten my coffee and Cheerios. I still consume cookies and pies, both of which are sugared. Before I started using the stevia, I had one dental cavity after another. For the last 10 years, I have had NO cavities. My dentist said ,"Don't tell anyone, it might be bad for business!

I think ConsumerLab's analysis is pretty fair and accurate. I use very small amounts of stevia in the least-processed form I can find from my local natural foods store. It is a loose very fine (almost like talcum) dark green powder in bulk that I scoop out of a bin. I would avoid any brand-name stevia containing erythritol or dextrose which are most likely made from GMO corn. While getting any food product not grown in your own garden or locally, from its natural state to your kitchen involves a certain amount of processing, highly processed, modified, compounded, or enhanced products are not your friend. Doing online searches for "dangers of processed stevia" could give you more insight.

I have been a consistent user of stevia for over 20 years. At first I found it to be bitter and had a hard time using it. However, after carefully adjusting the dose, I have learned to love it and know it is healthier for me and my family than most other sweeteners. When baking, I substitute coconut sugar for regular white or brown sugar and then augment it with a little stevia (because coconut sugar is not as sweet as regular sugar). Coconut sugar is much healthier because it has a lower glycemic index than regular sugar.

Greetings all; Speaking anecdotally, I have had no bad reactions to any of the various forms of stevia I use (going on 16 years of daily use). On the rare occasion I have come across bitterness, a small pinch of either sea salt or Himalayan salt in the beverage has eliminated the bitterness (it is a delicate balance with bitter vs. salt; but once achieved, you taste neither). Thanks for the opportunity to comment.

Thank you for sharing your experience with this Paul. You may be interested in our CL Answer about Himalayan salt:

I find that stevia, besides tasting very bitter, also gives me horrific headaches. Neither I or my family have any financial interest in stevia or other competing product.

December 2, 2020

I too have headaches as well as a copious nasal discharge when using stevia. Couldn't figure out why until I researched it and found that stevia is part of the ragweed family. Not sure if that's why I get the headaches but it sure points a finger to the runny nose. I do not have any financial interest in stevia or other competing product.

I have not found stevia to be accepted by my family's pallet as much as Xylitol (I have no financial interest in either product). I purchase the Xylitol made from birch trees as opposed to GMO corn. Other than the cost being prohibitive, I'm surprised many people I encounter are not familiar with it. Does anyone know of studies on xylitol's safety similar to those mentioned in this article on stevia? Thank you.

January 26, 2020

We use both xylitol and stevia. I never imagined either would lower my blood sugar per se, but I have no doubt that using them instead of sugar would do so. I went from borderline diabetes 2 to a normal blood sugar level by this substitution, and still manage to satisfy my sweet tooth! The reason fewer people are interested in xylitol than stevia, I suspect, is that xylitol still contains calories (about 2/3 those of sugar) even though it does not raise GI significantly. But it does taste better!

January 26, 2020

My understanding is that xylitol is safe for humans but dangerous for pets. I would appreciate Consumerlab providing some information on that.

Hi George - You are correct. We've added information about this to the answer above.

Thank you for this information. I am confused, however, about why the extract would be recognized as safe, but not the natural whole leaf it comes from? I grow Stevia and have been putting a few leaves into my salad straight off the plant. Would that not be advised?
January 25, 2018

Hi Donnie - Stevia leaf is not necessarily unsafe, but apparently no one has submitted documents to the FDA about the safety of plain stevia leaf or crude stevia extract, only companies selling pure stevia extract have done that.
