Stevia Benefits for Weight Loss, Side Effects and Why It’s So Good as a Sugar Substitute

Natural sugar alternativeStarting to use stevia regularly may well be one of the most beneficial things you ever do for your wellness and wellbeing.

Not for the nutrition it gives you, but rather for what it helps you substitute in your diet — sugar.

Here’s why stevia is so much better as a sweetener than sugar, the many benefits of making the change, potential side effects and the best tasting one I’ve found to sweeten food and drinks.

What is Stevia?

Known scientifically as Stevia rebaudiana, is a small herb that originated in South America. Its leaves contain unusual compounds, like steviol glycoside and rebaudioside-A, that mimic the sweetness of sugar without any of its negative effects.

The raw leaf of this plant is around 40 times sweeter than regular table sugar. While a good concentrated organic extract is approximately 200 times more sweet.

The leaves of this plant have been used to sweeten foods and drinks for more than 400 years in South America. In countries like Japan, South Korea and Taiwan, stevia products have been popular for decades with very few reported side effects.

Purified extracts have been generally recognized as safe in the United States since 2008. However, whole leaf powders and other products do not have GRAS status and are not approved by FDA as a food additive.

Weight Loss Benefits

The main reason why taking stevia is so good for your body and overall wellness and wellbeing is because it helps replace high calorie sugar as a sweetener.

A high dietary intake of glucose, fructose and especially HFCS, increases your risk of many conditions and makes weight management extremely difficult.

Due to its extreme sweetness, just one drop of of concentrated extract is equivalent to a teaspoon of sugar, with no calories to store as fat.

Dental Care and Preventing Tooth Decay

Stevia has been found by the Purdue University Dental Research team to reduce bacterial growth and plaque formation on teeth, thus reducing tooth decay risk.

Sugar is particularly bad for cavities so swapping it out with stevia extract is especially beneficial for your teeth.

How to Use Stevia

The most obvious and immediate use for stevia is as a substitute sweetener in hot drinks like coffee or tea.

The extract is heat stable up to 392 degrees Fahrenheit (200 degrees Celsius) and a single drop is usually enough. Those who love their sweetness could try two or even three drops but you shouldn’t need any more than this.

Cold drinks can also be sweetened with stevia. Add a drop of the extract for extra sweetness without the calories.

A couple of drops mixed into a homemade muesli recipe removes any need for other sweeteners. It can also be used in most forms of baking and other food recipes that call for extra sweetness.

Potential Side Effects and Allergy Symptoms

Warning for Pregnant Women

Refined stevia extracts with rebaudioside-A have GRAS status and are considered safe for moderate use as a sweetener.

The FDA notes that whole leaf products are not generally recognized as safe and therefore not recommended for use by pregnant or breastfeeding women.

Some stevia products also use sugar alcohols as an ingredient which may cause digestive upsets like bloating and gas and should be avoided.

Stevia Allergy

A very small number of people have reported a possible allergic reaction to stevia. Symptoms may include:

  • Shortness of breath or difficulty breathing.
  • A swollen tongue, mouth or throat.
  • Dizziness, brain fog and headaches.
  • Sudden skin rashes and itchiness.

Consult a GP if these symptoms are severe or worsen over time. People who report an allergy to stevia are also usually allergic to other plants in the ragweed family, of which herb is a member.

For the vast majority of people though, an allergy is extremely rare and using it is a safe and very beneficial way to cut down on their simple carbohydrate intake.Whole leaf stevia rebaudiana

Candida Die Off Symptoms

Some negative reactions attributed as stevia side effects, like brain fog and headaches, are more likely to be caused by candida yeast die off.

When you replace sugar in your diet with stevia you may temporarily feel worse as candida is being starved of its favorite food. This can increase sugar cravings but you’ll improve your wellness and wellbeing in the long run if you can get through them.

It’s important to keep stress levels in check to reduce cravings for sugary foods and drinks.

This calming Organifi Gold superfood powder can reduce stress and tension and help you get a better night’s sleep. This leads to lower tension and more effective weight loss.

The Best Tasting Type

Early versions of stevia apparently had problems with a bitter aftertaste. This is uncommon in extracts these days and I’ve never experienced it personally.

When researching a good tasting brand to buy for my own kitchen I read many customer reviews and tried around half a dozen versions before settling on Now Foods Better Stevia.

It’s organic yet one of the least expensive ones. I really like the long lasting sweetness of it in my teas or mixed into my food more than any of the others I’ve tried.

Do you use stevia in your kitchen and have you found your simple carbohydrate intake cutting down since you started substituting sugar with it?

The long term benefits can be significant for such a simple and inexpensive change. If you’ve never used it before I’d highly recommend giving stevia a try.

I’ve written a number of recipes on this site and others where one of the main comments is ‘Can I add sugar to sweeten this’. This article will be my response from now on.


I know I read that up there that stevia does not feed candida, but could it potentially feed any parasites or organisms living in my body currently?

Hi Tiler,

I don’t believe so. Stevia is not an energy source. It just has a strong effect on your tastebuds.

All the best,



I know Stevia is this awesome natural sweetener for most of the population, but I wonder if you have noted that it can cause an allergic reaction in some people … like me. It is in the daisy, ragweed, and chrysanthemum family, so people who are allergic to those things need to proceed with a bit of caution. I did not, and landed in the ER with a severe allergic reaction. Life has become a bit of a challenge now as the popularity of Stevia grows and is an ingredient in more and more products. I know instantly if I accidentally ingest it now. It’s taking some time for me to train myself to read labels carefully. I also have to be careful to notice when it is listed as Reb A instead of Stevia.

Thanks for all you do. I am enjoying reading your website.

Hi Laura,

I’m sorry to hear you have had problems with an allergy to stevia. Looking into this, it doesn’t seem to be well understood, with this study they say they haven’t found allergic reactions to stevia with the highly purified steviol glycosides, whereas there are other people online like you who have experienced allergic reactions. Most usually say they also have a ragweed allergy.

Not suggesting you try it but just wondering if you remember whether you were using a purified steviol glycoside liquid or an extract that also contained rebaudiana A as they are two different compounds?

Personally, stevia has been great for me as I have a very predictable and far more commonly reported reaction to aspartame and, like you, have to really watch out for it on ingredients lists if I want to avoid a splitting headache.

Thanks for your comments. I’ve updated the article to address stevia allergy.

All the best,
