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).

This may sound like an odd question but does one have to worry about GMOs and stevia production?

well, i have been taking a product called Vega Electrolyte Hydrator. it has Stevia in it. i thought i would do my own research just like it has been suggested above but in this case i am frustrated how much time and emotional energy goes into these respoces that dance around the issue. Is Stevia bad or not? reference me the study that says yes or no.

I am amazed that someone would post that "aspartame has been proven safe". But while there are some studies proving it safe, many, many more studies have proven it to be unsafe, or of questionable safety. Why is it that the only studies proving it safe are those done by, or in some way connected to or supported by the makers of aspartame? In the past decade people have begun to realize just how unsafe and dangerous Aspartame is, and as a result its popularity and sales are waning greatly.
Stevia was banned in the U.S. until companies like Cargill, Coca-cola and Pepsico petitioned the FDA to have stevia declared as GRAS product. Shortly after these giant corporations made their petitions, the FDA did in fact grant their wishes and bestowed a GRAS label upon rebaudioside A (rebiana)(,the compound that gives stevia a sweet taste.),thereby allowing these companies to bring to market their own stevia based products. Hmm., is this really a coincidence? Just something to think about.

Aspartame proven safe? Oh's known to have over 92 side effects including multiple cancers and's killed half the rats they tested it that's a fact.

I love honey and used to keep bees,
until CCD made it difficult to keep
Them alive. Systemic pestisodes
are In the nectar they make the honey
From. It kills the bees. Don't know
How safe honey is anymore.

Honestly, this is simply just too silly to be arguing about. Reb A, Stevia, etc. are not harmless, just as sugar and salt are not harmless. If one does their homework for a while, one will see that the FDA has very little to do with anything. They are there as a security blanket, and even though their hearts are in it for safety, we often forget that Pharm companies ARE the big business, and pharm companies are a part of our "beloved" government. Money talks in this world. I urge people to look into Codex Alimentarius, which rules out the FDA anyway. Anything going against Codex laws are promptly done away with, and that includes organic farming, Amish communities, ingredient listings, "safe" or "unsafe" chemicals. 7 out of 10 FDA-banned chemicals were reintroduced via Codex rulings. Let's not fool ourselves any longer about this. The FDA can only go so far before somebody else steps in and says: "No, we can't make any money from this, so we need to change the rules." What we put into our bodies is, and always should be, our own business... not a part of Big Business... Stevia may absorb some nasty chemicals while it's growing in the wild, but we put those chemicals there... let's not argue over it.

I use stevia in the raw and wonder if that is safe. Perhaps I should just grow it in my yard and then I will know it is safe.

"You think because it's a pretty leaf stevia is harmless, and chemicals like aspartame and saccharine are poisons. Fact is, aspartame has been proven safe, despite your conspiracy theories, while stevia actually may have some adverse effects. Deadly chemicals grow in nature. Even your raw unprocessed honey can have deadly all natural pathogens in it. Get over this delusion that natural = harmless and anything synthetic is a corporate plan to poison us. The FDA is trying to keep people safe, not trick them."

You are in idiot if you really think this, or just work for the FDA/Govt. The interest of the FDA is to protect the interests of the Pharm industry. "We say it's safe, but it causes cancer... oh yeah, our partner makes cancer meds, let us help you out." Don't be naive, just because the FDA says it's ok, doesn't mean anything is safe. They turn their heads, period.

Do your own research, be responsible for what you consume and don't beleive that any one has your best interests at heart.

anyone that thinks aspartame is healthy is an idiot. Its been proven to cause cancer among other things it also raised my mothers thyroid. But were talking about Stevia not aspartame. Bottom line tho, i dont trust the FDA anyway. High Fructose Corn syrup isn safe either, and its in EVERYTHING! Not to mention our chicken nuggets arnt really made out of chicken anymore since they sent that stuff off to china to be processed without the oversight of the FDA. Wake up people!!! Start doing your research.

I just wonder how intense the research was on stevia how many of the case studies produced problems with reproduction? what was the ratio are we talking about a 99 percent possibility? are we looking at more like 1 out of 10. and were there any other adverse effects?
