Stevia Side Effects – Is it safe?

There’s a lot of conflicting information in the health space, including with stevia. Inside this post, I share my real-life story with stevia side effects and answer the question, is it safe?

Nutrition is constantly changing. Fads come and go, and new foods come and go. It is easy to get caught up in the latest “health” craze and “super” foods out there. I’ve fallen short of this numerous times. 

Truthfully, there is no such thing as a perfect diet, but that doesn’t mean we shouldn’t strive for one. One of the latest health foods that many have fallen into this category is stevia. Now, I’m not trying to say that it is wrong or something we should eliminate.

Many studies suggest that stevia has beneficial properties to the body. Some even showcasing how it can prevent tumor growth by reducing blood sugar levels. 

It has also been used in other cultures for centuries. 

Showcasing that we can’t lump all stevia into the same category. I’ll answer which forms of stevia are best at the bottom of this article. 

While stevia may be safe for a group of people, we must remember how one person reacts will be different from another. Some people will have negative stevia side effects. This is why body awareness is essential. Everyone’s body has different needs and requirements. Ultimately, your body will let you know if it doesn’t like something. 

The most important piece of advice I can give you: You be your own judge. You know your body best! If you do not react to stevia, by all means, continue to include it. But if your struggling with symptoms that never seem to budge, stevia could be a culprit. 

Listen to what your body is telling you and respond accordingly.

our stevia side effect story:

Stevia, a popular zero-calorie, “natural” (that term is debatable) sweetener used by so many health-nuts today and at one time included me. I must admit there were some amazing perks to stevia. It dissolved easily in drinks and could even be used in baking. Minus a slight after-taste issue, it seemed to be a great alternative to sugar.

So we used it, and frequently for a while. 

I had found a “natural” lemonade sweetened with stevia instead of sugar that my oldest daughter loved. Naturally, I thought it was “healthy,” so I didn’t have to monitor how much she could tolerate.

I allowed one and potentially two packets of this lemonade a day. She really liked the taste and would prefer this to nearly any other beverage offered. Of course, it tasted sweet. 

This continued for a month or more, but as she continued to drink it, we noticed her frequently complaining of her legs hurting. Over and over, I would hear her say, “my legs hurt, mommy.” She was also becoming more sluggish, even falling asleep on a five-minute drive to preschool.

I asked google…

At first, I pushed it off as growing pains, but I started to get more concerned as the weeks continued. She complained daily of leg pain. She could barely keep herself awake – which was significantly different from the very high energy child we had once been dealing with. 

Naturally, I started to panic and asked Google what it could be. This was a big mistake and one I hope to prevent you from making. While Google had all of the apparent diagnosis down, I kept thinking and researching. 

Then one day, my mom stated the obvious. One the nutritionist should have picked up on. But sometimes, when things are right under your nose, it’s easy to miss them. She asked if anything had changed in her diet over the last few months. 

And at that moment, a light-bulb when off. The lemonade! 

After I made the connection, I started to dive into stevia. Something that had been on my mind to research further. Turns out the stevia was the culprit leading to the crazy exhaustion and muscle weakness my daughter was experiencing. 

We cut the lemonade and all stevia from her diet. In a matter of days, she was back to her usual high-energy self. 

I also noticed a difference in my brainpower. I had been having slight headaches off and on. Ironically it fell in line with the days I indulged in a stevia-sweetened drink. 

So I want to fill you in on my findings. Informing you stevia may not be as beneficial as everyone originally thought. 

It’s natural, but what are the stevia side effects?

First, let’s start here with the basics. Just because it is natural doesn’t mean it is safe. Technically, stevia is an herb. Which means it is natural and grown from the earth. However, like all herbs, they have powerful side-effects. Some positive and others negative. 

stevia taxes the adrenals:

Another response to stevia that some experience is hypoglycemia. Which is a leading reason it’s studied for use in diabetic patients. It could potentially help lower their blood sugar levels without excess insulin.

But in non-diabetic individuals, experiencing a sweet taste from food that is not going to provide glucose confuses our body’s sugar-handling process. Eating a sugar-free sweetener like stevia can trick the body into a state of hypoglycemia.

As Kate, from Nutrition by Nature states:

Stevia is “sweet” on the palate, so the body assumes it is receiving sugar and primes itself to do so. Glucose is cleared from the bloodstream, and blood sugars drop, but no real sugar/glucose is provided to the body to compensate. When this happens, adrenaline and cortisol surge to mobilize sugar from other sources (liver, muscle glycogen, protein, or body tissue) to bring blood glucose back up. 

As I mentioned above, stevia isn’t going to affect everyone’s blood sugar the same way or to the same degree. Some will not experience the blood sugar drop, while others may. Those who do see a rise in stress hormone leading to the hypoglycemic effect tend to experience headaches, muscle cramps, and uncontrolled fatigue. 

As Lauren from Empowered Sustenance states:

The frequent release of the stress hormones (adrenaline and cortisol) in response to the Stevia-induced hypoglycemia can be damaging to our adrenal glands and overall health. These stress hormones are designed for the fight-or-flight response, not when eating a meal. The consequences of increased cortisol include a suppressed immune system, increased inflammation, increased abdominal fat, and lower thyroid function. 

stevia has a hormonal structure:

Stevia also contains chemicals responsible for the sweet taste of stevia. These are known as the steviol glycosides. There are at least ten different steviol glycosides present in the stevia plant. The purified version or manufactured form of stevia often isolates one or two of these steviol glycosides. 

Steviol glycosides are structurally very similar to certain plant hormones (gibberellin and kaurene). This means that stevia has a hormone structure. This hormone-like structure can act as a mutagen, meaning stevia can change the genetic material, usually of DNA, increasing the frequency of mutations. 

Regardless of whether stevia causes genetic mutations, we should still take caution in this, especially those with an autoimmune disease in which hormones dramatically impact disease development and progression.

stevia feeds our sweet addiction:

Let’s be honest, our sweet tooth doesn’t need any additional help. More sweet flavors only enhance our addiction to sweet foods. The more our body gets a taste for sweet foods, the more difficult it is to adjust to a normal lifestyle, where real food fulfills that sweet tooth. 

What we know, stevia is really sweet, making natural sources of sweetness incomparable and unsatisfying. 

The big idea: If you use stevia regularly and don’t experience negative consequences, go ahead and keep using it but do it in moderation. Even though it doesn’t have “calories,” it is still sweet, making it potentially addictive. Most importantly, listen to your body! It knows more than any health claim on the market. 

The best form of stevia. 

If you don’t react to stevia, know there are good options and poor options like all things. The safest form of stevia includes whole dried stevia Leaves and Sweet Drops Stevia. This is a pre-made stevia tincture that comes in various flavors. 

Steer clear of the white powdered substance you can buy at the store or anything that contains additional processed ingredients. If you use stevia, make sure it’s in the whole leaf form—the only form studied in researched and used for thousands of years in other cultures. 

**It’s fair to say my daughter was not consuming a natural form of stevia. Therefore, the stevia side effects could have been from a bad form.

I will end this post with Mayo Clinic’s advice towards stevia:

“Because of stevias blood-sugar-lowering and blood pressure-lowering potential, the sweetener Stevia should be evaluated first on an individual basis, before being regularly used by anyone suffering from hypoglycemia or general glucose tolerance problems. Feedback has been mixed, with stevia being well tolerated by some, but less so (i.e. aggravated low blood sugar symptoms) by others. There are stevia side effects that we must be aware of. Pay attention to how your body responds.”

  1. Hi. I have been struggling with pain in my legs and feet. Also tingling and stinging in my legs and feet also. Sometimes it feels like I’m being stuck in my feet with a hot electrified needle. I have used Stevia, the white powder form for about 3 years now. I never thought the problems I’ve been experiencing was the Stevia. Not until I read your article. Thank You for opening my eyes to this. I actually thought I had become grain intolerant.

  2. I think dried stevia leaves are better, what’s your opinion?

  3. Edwina Sloan says:

    I am having a lot of pains in my thighs. This is fairly new but I have been using stevia for years. Could this be related?

    • Payton Schirm says:

      It certainly could. It’s definitely something that can build up over time as your body continues to react to the stevia. It is worth leaving out to see if the symptoms subside. Keep me posted!

  4. karen smith says:

    I am one of those people who find the effects of Stevia intolerable. There are so many products I would like to take but for the Stevia. Cannot find any counter measures but maybe lemon or iodine. No confirmation of this. Does anyone have knowledge and would agree to help me ?

  5. Mary says:

    Well shoot! I’ve used stevia in my coffee (several cups, daily!) and to sweeten a vinegar beverage, for almost two years.
    I’m having worsening muscle and fatigue. Guess I’ll be taking some time off stevia to see if it’s to blame.
    Thanks for sharing!

  6. Sam A says:

    I usually don’t share experiences like this but I think it is important as stevia is everywhere – I also found stevia somewhat built up overtime. I didn’t get to the place of sore muscles but my migraines which are typically from weather patterns/lack of sleep went from 1 every few months to 1 migraine a week.

    They drastically increased after taking a green supplement with stevia – I stopped taking it after seeing doctors and my migraines went back to my normal 1 every few months.

    • Toni says:

      I actually did my own little experiment with this because I get migraines as well and started putting 2 and 2 together that Stevia was triggering them. I started having migraines on a daily basis, (yes, I said daily) after having my usual morning coffee and on the days when I didn’t have sweetened coffee everything was fine. I’m back to drinking it black or with regular sugar, but I haven’t been getting migraines as frequently since I stopped consuming stevia. Thank you for your post! You’ve made this much more validating.

  7. Madelyn says:

    Is this the same for other zero calorie sweetners? I have stopped using the stevia because of taste preference and we now use monk fruit drops or lakanto powder ( monk fruit and erythritol mixture).
    My daughter used to complain of leg pain and I too believed it to be growing pains! Now I’m wondering if it was when we were consuming the stevia.. I appreciate your article and would love your opinion about the other sweetners!

    • Alexa Schirm says:

      Yes, most zero-calorie sweeteners have a similar effect. Although stevia was supposed to be considered one of the more natural ones. Monk fruit I believe has not been show to have quite the drastic blood sugar swings. I believe it is because of the amount they use to get the same flavor. I would use monk fruit and erythritol over stevia.
      I’m glad this was beneficial for you. Let us know if you have any other questions.

  8. Timothy Elias says:

    I feel extreme fatigue if I have a little too much stevia. I have also eaten the leaves from our stevia plant, and had ketchup made with stevia, I didn’t notice anything from them.
    It is really too bad that stevia bothers me in this way as it is the only sweetener I have tried that I can tolerate due to lyme disease and possibly candida. Stevia is also supposed to be good for fighting lyme.

    • Alexa Schirm says:

      It is supposed to be helpful. I think it shows we all have a threshold that our body can handle and each person will respond differently. Keep listening to your body! It does know best! Let us know if you have any additional questions!

  9. Pam says:

    Thank-you for your post. I had stevia today for the first time and I am experiencing numbness and leg cramps (on my calf on my left leg, and in my thigh in my right leg). Your post was very helpful to identify my weird cramping! I’m sorry that happened to your daughter, however, I appreciate that you shared your experience.

    • Alexa Schirm says:

      I’m so glad this article is beneficial. It is a more common problem that I’m afraid more people aren’t aware of. I’m so grateful you are listening to your body. Keep me posted if you have any further questions!

  10. Kel Liew says:

    Thanks for the insightful article! After much googling for an answer for my recent piercing pain on my eyes, I ended up here (reading all the above comments). I did experience daily “piercing” effects on my eye (between 3-10 times) since June 2021. I started a Ketogenic diet back in Feb 2018, and I’ve been using Stevia almost daily. Btw, the stevia I’ve been using contains erythritol.

    I tried switching to allulose as an experiment and the pain seems to reduce. Then I tried the Stevia again, and the symptoms seems to come back after a few days/weeks..

    Recently (26 Oct) I purchased the Monk fruit and erythritol mix, and the weird throbbing pain came back a few times.. Will probably monitor a few days, else I’ll give myself a break (say 14-30 days) from these artificial/natural sugar, and see if the symptoms go away ^^

    * I’m wondering if it’s the erythritol or stevia now 🙁

    Thanks everyone~*^^

    • Alexa Schirm says:

      It could be a reaction to both. But I love your art of experimenting and figuring out the source. Keep paying attention to your body and trust what it is telling you. Let us know if you have any additional questions!

  11. Pamela says:

    Thankyou for this information. I had a reaction yesterday to a breakfast smoothie I made with a top brand protein powder: an hour or so after drinking it I had brain fog, mild anxiety, and moderate fatigue… suspected the stevia as I’ve never (knowingly) used it before. All makes sense now thanks to your article 🙏

  12. Ashley says:

    Omg!! I’ve been having facial numbness that radiates from one side to the other and down my chin (along with muscle fatigue in my jaw and right eye— so much so that it feels like my skin is dropping) and I’m thinking that it is related to an increase in my stevia consumption over the past few weeks. I’ve also had stomach issues and some anxiety that I’m thinking are now connected to this same thing. I just stopped all consumption of stevia products yesterday (first full day without them). I still have the numbness in my face today. From your article it looks like it may take a few days to get fully out of my system. Maybe a week? This article was so encouraging bc there’s not a lot of stories out there about these strange reactions. I’m really hoping this is the key bc dealing with this numbness is scary for sure, certainly after looking on google lol!!

  13. Curtis says:

    I have multiple Stevia drinks each day and have been experiencing muscle fatigue and terrible cramping in my arms and calves. I was on vacation for a week and it was not available and they went away. Got home and within a few days they are right back. Going with water for awhile to see if it subsides again.

  14. Jessica B. says:

    Thankyou for sharing this information. I believe that I have developed epilepsy due to consuming stevia over the last 6 or 7 years. That’s the one thing that changed. Hypoglycemia and Epilepsy are know to be related. I have quit 2 weeks now. My mouth would itch, that has gone away.

  15. elizabeth M says:

    I cannot tolerate any form of stevia. Most weight loss recipes require stevia to be used instead of sugar. Is there a conversion chart showing stevia to sugar? I cannot find one.

    • Alexa Schirm says:

      1 tsp of Stevia = 1 Cup Sugar. I prefer to use an alternative sugar such as Coconut Sugar. Most recipes can have the sugar cut in half and still maintain a sweet taste.

      • April Graham says:

        Dr Livingood has a good sweetener comparison. I am sure you could look it up on YouTube or google it. Very informative.

  16. GiGi says:

    Oh my gosh, I just bought 12 bags of the powdered stevia, a sale of course. I have been using it a few years now and I am on gabapentin becuase my legs cramp and hurt so much. I thought it was nerve damage because my bad spine…… maybe not. I am going to quit using it and see what happens,. Thank you so much for writing this article!
