Is Stevia an Endocrine Disruptor? Separating Fact from Fiction
At Feed Me More Nutrition, we believe in transparency and using only the best ingredients to fuel your body — and that includes our choice to sweeten our supplements with stevia and monk fruit instead of harmful artificial sweeteners. But with some misinformation floating around online, we want to address an important question head-on:
Is stevia an endocrine disruptor?
Let’s break it down with science, not fear.
What is Stevia?
Stevia is a natural sweetener derived from the leaves of the Stevia rebaudiana plant. The sweet components — primarily steviol glycosides like Rebaudioside A — are 200 to 400 times sweeter than sugar and contain zero calories, making them an attractive alternative to artificial sweeteners like sucralose or aspartame.
Feed Me More Nutrition exclusively uses high-purity, clean stevia extract, paired with monk fruit, with no fillers, no maltodextrin, and no erythritol.
The Claim: Does Stevia Disrupt Hormones?
You may have seen blogs or videos warning that stevia is an endocrine disruptor — a substance that can interfere with your hormone system, potentially affecting metabolism, reproduction, or other bodily functions. This is a serious claim, and we took it seriously.
So we looked at the actual research.
The Truth According to Scientific Research
1. Regulatory Safety Reviews
• FDA: High-purity stevia extracts (steviol glycosides) are designated as Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration.
• European Food Safety Authority (EFSA): Conducted a comprehensive review in 2010 and again in 2020 — no reproductive or hormonal effects were found in humans at accepted intake levels.
• Joint FAO/WHO Expert Committee on Food Additives (JECFA): Set an acceptable daily intake (ADI) of 4 mg/kg body weight, based on lifetime studies in animals — well above typical human use — and concluded no adverse hormonal effects.
2. Human Clinical Studies
Unlike artificial sweeteners, stevia has undergone significant human testing:
• A 2016 review in Phytotherapy Research concluded that steviol glycosides showed no genotoxicity, carcinogenicity, or endocrine disruption in human trials.
• A 2018 randomized controlled trial published in Appetite found no changes in insulin, cortisol, estrogen, testosterone, or thyroid hormones in healthy adults consuming stevia over several weeks.
3. Where the Misinformation Came From
The “stevia as an endocrine disruptor” narrative largely stems from:
• Rodent studies from the 1980s and 1990s, which used unrefined stevia leaves or massive doses (hundreds of times human exposure levels).
• One 1999 rat study suggested possible antifertility effects — but used whole leaf steviain amounts no human could reasonably consume.
• These studies involved unpurified extracts or raw leaf use, which is not the form approved or used in supplements like Wake Up Unlimited Energy.
The purified steviol glycosides used in Feed Me More Nutrition products are molecularly distinctand go through strict testing and safety protocols.
What About Real-World Use?
We’ve been using clean stevia and monk fruit sweeteners for years at Feed Me More Nutrition — and the real-world results speak volumes. Thousands of customers have enjoyed our products with:
• No reported hormone-related side effects
• No crashes or energy swings common with artificial sweeteners
• Improved digestion and energy from removing toxins like sucralose or aspartame
And as someone who uses these products daily myself, I’ve experienced nothing but sustained energy, mental clarity, and performance.
So Is Stevia Safe?
Yes. Pure, organic stevia extract — like we use — is safe, non-toxic, and does not disrupt human hormones. It’s one of the cleanest sweeteners available, and it’s a massive upgrade from artificial chemicals in most mainstream energy drinks and supplements.
Why Feed Me More Nutrition Stands Apart
While other companies cut costs with sucralose, aspartame, acesulfame potassium, or artificial dyes, we go the extra mile. Every supplement we sell is:
• Sweetened with 100% Stevia and Monk Fruit
• Free of artificial colors and sweeteners
• Vegan-friendly
• Scientifically dosed
• Manufactured in the USA in FDA-registered, GMP-certified facilities
