Is Stevia Bad For You?

~Brock Pominville BS, CSCS, LMT

Most sources say no, stevia is not harmful, but it has gotten a lot of scrutiny lately. Let’s get into what the data really shows about the plant and natural sweetener known as stevia. Just for a second, forget what the internet has told you. Yes, I know this is also the internet, but I'm going to explain the research in a language even a 5th grader could understand, and not just cry wolf at a headline or study title. We are going to look at exactly what the research really tells us.

Before we get into the real research, I’m sure you’ve heard, or had these questions before:

Why use stevia when you could just use sugar?

Unlike sugar, stevia:

  • Does not spike blood sugar (no sugar crash)
  • Contains zero calories
  • Supports steady energy
  • Has metabolic benefits when compared to sugar
  • Supports weight management (fewer calories)
  • Does not contribute to tooth decay
  • Is perfect for diabetes

Is Stevia Processed?

There’s a lot of confusion online about stevia.

Some claims say it is made with “harsh chemicals.” That’s outdated for most commercial stevia. Here’s how most companies make stevia now:

  • Stevia starts as a plant leaf
  • The sweet compounds are extracted, often using water-based methods just like tea.
  • Some modern processes use CO₂ extraction, a clean and widely used food technology
  • The final ingredient is purified and tested for safety
  • Some compounds from stevia can also be derived and extracted by fermentation.
  • These water based extractions on a basic level are similar to brewing tea. Then if it were tea, you would then evaporate all the water from the cup and filter/purify what’s left after all the water is gone. These newer methods are pretty simple.

Although it's rare that a company still uses “petroleum based solvents” like claims that have been made online, it is still an option (it’s cheaper than the healthier methods).

Our electrolytes are built for your family, so we do not use these harsh solvents, only safe and healthy extraction methods for your families hydration. Even though it costs us more, because your family's health is our top priority.

Why Does Stevia Sometimes Have A Bad Aftertaste?

Taste matters, especially for families with picky kiddos.

Some stevia products can have a bitter aftertaste, that's mostly due to bad quality and cheap stevia.

Evident Electrolytes uses only the highest quality stevia extracts. We combine two different pure extracts from the leaf, (Reb A and Reb M) to create a more balanced flavor. This reduces the aftertaste that some people notice from low quality or single compound extracts.

The result:

  • Clean, smooth taste
  • No harsh sweetness or bitterness
  • Easy to enjoy daily

Why Does My Stomach Feel Weird After Drinking Something With Stevia?

There can be sensitivities with any food. Some examples include: Dairy, onion, gluten, eggs, sugar, and nightshades like tomatoes.

Some people tolerate certain foods better than others.

Although it’s very uncommon to be sensitive to stevia when it’s pure, high quality, and in low doses like Evident Electrolytes, it can still happen to ultra sensitive individuals.

But again, it is very uncommon that stevia itself is the actual problem. Low quality, another ingredient maybe not disclosed on the label (proprietary blends and flavors), or less than ideal manufacturing practices is more likely the problem.

Always get third party tested supplements to ensure better quality.

Is There Research Showing Stevia Is Bad For You?

Okay now into what you came here for.

You may have seen claims online that stevia is unsafe.

These claims usually come from a small number of older or low quality studies.

Let’s look at them clearly.

1. Studies Showing Stevia Is Bad (most are 30+ years old)

Some early research suggested possible concerns.

But these studies had major limitations:

  • They used crude, unpurified stevia extracts (not what is used today)
  • Extremely high doses, often 100x normal human intake
  • Done in rats, not humans
  • At extreme levels, almost any substance can show negative effects, like water or sugar!
  • Results were not reproduced in later research

Modern safety reviews from global health agencies have also concluded these findings are not relevant to today’s purified stevia products (EFSA, 2010; EFSA, 2024).

2. Lab (Petri Dish) Studies

A newer studies tested stevia on bacteria in a lab. It showed changes in a bacteria that is found in the gut.

But:

  • They are done outside the human body
  • They are not done with your entire gut, only isolated single bacteria.
  • They don’t include digestion, metabolism, or real dosing
  • These effects have not been found when scientists have replicated these studies with real humans

These shouldn't be completely thrown out but they are far from proving anything.

So Is Stevia Good Or Bad For You?

When you zoom out and look at all the research:

  • Hundreds of studies have found stevia and steviol glycosides (sweet compounds in stevia) to be completely safe.
  • Major global health organizations (WHO, EFSA, JECFA) all agree.
  • Stevia has been studied across more than a dozen countries and evaluated by global health organizations using data from around the world.
  • No human studies have shown negative effects from normal dose pure stevia.
  • The conclusion is consistent across Europe, USA, Canada, Asia, etc: stevia is safe with normal intake.

Overall Research On Stevia

  • 50+ studies show beneficial or no effects
  • 150+ total studies and reviews evaluated by global health authorities showing it is safe
  • ~5–10 total “negative” studies. These studies are commonly cited online but the results are rarely explained or understood.
    • The negative studies on stevia, around 7 total papers, are 30+ years old, lab-based, or high-dose rat studies. There are none showing negative human outcomes with pure stevia.

Why This Difference Matters

Not all studies carry the same weight. Studies using humans = strongest real-world evidence.

What that means: The best kind are tests done on real people, because they show what actually happens in real life. This is the gold standard for research.

There are no negative results from studies of this kind.

What This Means for You and Your Family

  • Stevia has been extensively studied for decades
  • The strongest and most modern evidence supports its safety and tolerability
  • The small number of studies with concerning titles are outweighed by explanation of the results and a much larger body of higher-quality, human data/research
  • It is one of the most studied and widely accepted natural sweeteners available today, safe for the whole family

A Better Approach: Naturally Sweetened with Stevia

We chose stevia extracts (Reb A, AND Reb M) as a natural alternative to added sugar. A plant-based, zero calorie sweetener used around the world for you and your family.

Beyond Our Natural Sweetener

Why Families Like Yours Choose Evident Electrolytes

For you. For your family. For every day.

  • Clean, simple ingredients including flavoring
  • No added sugar (no sugar crash!)
  • Science-backed formulation from mineral inadequacies
  • Thoughtfully designed for daily use for the whole family
  • Balanced taste without compromise

Your body needs electrolytes like potassium, magnesium, and sodium to:

  • Absorb water
  • Support energy and focus
  • Have a healthy blood pressure (more potassium and moderate sodium for most)
  • Keep muscles and nerves working
  • Support hundreds of processes in the body

And here’s the kicker, most people are not getting enough magnesium and potassium

What Most Drinks Get Wrong

Many popular “electrolyte” drinks rely on:

  • Mostly sodium
  • High amounts of sugar
  • Artificial sweeteners or flavors
  • Overly complex formulas

These lead to:

  • Over consuming sodium which stresses the heart and kidneys
  • Energy spikes and crashes
  • Unnecessary calories or insulin spikes
  • Ingredients you may not want, or need for your family

Choose Evident Electrolytes instead for clean hydration, and minerals to support good nutrition. Always backed by science.
