Is Stevia Safe?

A. This year, a few noncaloric sweeteners made from an extract of the Stevia rebaudiana plant arrived on grocery-store shelves. The stevia plant has a long history of use as a sweetener in South America. These new sweeteners—sold under brand names like Truvia and PureVia—include a highly purified extract of stevia called Rebaudioside A (a.k.a. Rebiana or Reb A). Reb A is 200 times sweeter than sugar and does not raise blood sugar.

Until December 2008, stevia and its derivatives could be sold in the U.S. only as dietary supplements, due to safety concerns. In the 1980s, animal studies linked stevia with adverse effects on fertility and reproductive development and possible genetic mutations. But in 2008, the makers of Truvia and PureVia submitted research to the Food and Drug Administration regarding Reb A’s safety and petitioned for it to become a generally regarded as safe (GRAS) ingredient.

The FDA affirmed the GRAS status, but did not change the previous ruling on stevia. “Reb A is different than whole-leaf stevia or [other] stevia extracts, which can only be sold as dietary supplements,” says FDA spokesperson Michael Herndon. “Nobody has provided the FDA with evidence that whole-leaf stevia is safe.”

The Center for Science in the Public Interest (CSPI), a consumer advocacy group, believes that the Reb A’s GRAS status was granted prematurely. “In the past, FDA protocol required repeated testing in two separate animal species prior to approval, but in this case it didn’t,” says David Schardt, nutrition expert with CSPI. “We are not warning people to avoid Reb A, but the public should be aware that the FDA did not follow all the usual safeguards.”

Bottom Line: The FDA considers Reb A a safe sugar substitute, but has not approved other forms of stevia. If you want to use stevia, we suggest sticking with Reb A (look for it on the ingredient label).

stevia is not an "artificial" sweetener. it is natural; like sugar or honey. lets not confuse it with artificial sweeteners.

Stevia is safe but these other brands are adding sugar (think dextrose) to make it more palatable and pourable.. whatever. The difference between Stevia and sugar substitutes is that it is not a chemical, it is an extract from a plant (think mint extract or like someone said, vanilla) and it does not cause a glycemic reaction... i.e. the pancreas does not release insulin into the blood stream the way sugar and sugar substitutes cause it to do. It is a good product but you have to buy the one without the sugar added (which defeats the purpose *cough Truvia cough*). And for those of you who love Splenda, well you are loving your blood sugar going up too. It's made from sugar... well my Dad told me you can make explosives and poison from sugar...

Aspartame and all those others gave me a brain fog and are a bunch of mixed chemicals and Stevia has not given me any side effects.

I've been using liquid stevia (NuNaturals-alcohol free) for a hear and a half and it has "cured" me of my sugar-junkie mode. I bought a couple of plants as an object lessone for my friends to help them understand that in nature there really is a plant that is sweet without calories. I think of it like salt or vanilla. Just flavoring for my food. I have also been on a low carb (high fat) regimen and have lost 15 pounds in this year an a half without feeling hungry of deprived. Myr ecent blood work showed everything normal. I like add liquid stevia to my starbuck's. I also like to mix liquid stevia in sour cream or yogurt and eat it with fresh strawberries. To me it's like the best cheesecake.

Whether it's Stevia, Truvia, Splenda, Aspartame Sucralose or any other artificial sweetner, they all mess up my digestive tract. I get gas, bloating, gas, diarrhea, gas, pain, and did I mention gas. I also get burning itchy eyes. All that artificial stuff is realy nasty!

I've had it in drinks, gum, snacks, you name it. And I'm also starting to hear Doctors talking about the FDA and not just about food, they're saying that they, the Doctors, and the general public have been spoofed by the chemical and drug companies and their use of marketing to the public to force the FDA to approve these things. GRAS Does Not Mean it's Safe - rather it means it just won't kill you immediately.

Whenever I want to make a choice on a product, and I feel good about the ingredients, I make sure it hasn't been approved by the FDA. Then I buy it! I do not trust an administration that for years has been disregarding the public health, in the name of profit.

Sounds to me like Anonymous has an axe to grind with the FDA but contibutes very little to the actual subject matter.

Attacks on FDA and USDA are totally legit. They approve poisons everyday. Consider GMOs in this discussion? Definitely time to boycott.

I'm confused...shouldn't the brain react to the sweetness of stevia the same way it does other sweeteners? If it's the sweetness that causes the neurological response doesn't that mean any sweetener will cause it?

I actually bought stevia seeds to grow. Im a lactating mother and my babys skin rash raises up if I have processed sugar in my diet, especially white sugar. My child skin actually clears up without the artificial or processed sugars. Remember, our body is designed to to process plant foods for better nutrient absorpion with less stress to our system. Grow your own!
