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).

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?

Before I read or even noticed these articles, I became aware that my sugar blood count was always higher when eating high fructose corn syrup. Read your labels and keep asking that HFCS be removed from our food products.

You could never go wrong with some good old fashioned, non processed honey!

The problem is that it's almost impossible to get pure stevia extract (or whatever it would be called). Truvia et al are all diluted with non-nutritive filler talc and powders.

Go plant the stevia herb in your garden, muddle with some mint and tea and you have a refreshing dring from the garden, guess who effectively had stevia banned fromthe country while their product was being developed and sold to an unsuspecting country, try saccharine and good ole, Monsanto.
For those of us who cannot or will not use refined sugar, stevia seems to be the best way to go. I have never heard of the research being touted here.
I've had no issues with using it, I've had two kids while using it....
Lets look at the problems associated with the other pink and yellow sweeteners, there is where the problems exist.
