I originally starting using Iherb for my supplements as they're usually significantly cheaper then here and also offer more variety and higher doses such as for Vitamin D, see here: Vitamin D High Potency. I highly recommend them
Erythritol is a sugar alcohol listed around 3/4 as sweet as sugar and has almost no carbs or calories. Erythritol is the most tolerable of all the sugar alcohols. It comes in crystal form so most people usually grind it before using it in baking. It is often combined with stevia to make up for the short fall in only being 3/4 as sweet.
Now Foods, Erythritol, Natural Sweetener 2.5 lbs (1134 g) I used to buy the one below but this now foods one looks to be the best value now.
I've also just spotted an organic option: Now Foods, Organic, Erythritol, Naturally Sweet 1 lb (454 g)
Pure Erythritol 5lb which is close to 2 and half kgs!
Pure Stevia Extract 1lb which is close to half a kg, this is an awful lot as you only need a slight dusting to sweeten a coffee!!!
Pure Stevia Extract 28g a great way to test out whether you like the stevia before buying larger amounts!
If you use a crazy amount of stevia you can buy a kg of it and save more: Pure NuStevia, White Stevia Extract, 2.2 lbs (1 Kilo) just think careful with this, in that you don't want it hitting it's useby date before you use it up as a little goes a long way! Probably something best purchasing with some fellow low carb or sugar conscious friends and sharing it.
You can also purchase premixed stevia, they have a version mixed with erythitol as well as another verion mixed with maltodextrin (pictured in above photo of my first ever sweetener order), they do this to make the stevia easier to use. This can be a good way to see if you like it before attempting to buiy them seperately and mix yourself:
NuStevia, White Stevia Powder 340g , stevia mixed with maltodextrin
NuStevia, NoCarbs Blend 98g , this one is mixed with erythritol. I meant to buy this the first time but accidentally bought the white stevia powder with maltodextrin, so I have never tried this one.
Update: During a talk from Pete Evans it was bought to my attention that the white stevia powders are very processed and that you should only use the green stevia powder. I don't know what the processing involves for the pure stevia which is white so I can't say either way. I haven't tried the green powder as I have stopped using sweeteners with only the occasional tagatose but that's becoming more rare too. I'm not sure why but I just don't feel like sweet low carb foods anymore. For those that are interested I have found the link for you, Pete mentioned buying it from iherb so I assume this is the one he uses. Its just the organic stevia leaves ground to a powder and that's it. If you try it please let us know what you think apparently it tastes different to the white powder!Frontier Natural Products, Organic Powdered Stevia Herb 16 oz (453 g)
Remember the pure stevia is very sweet a little goes a long way, I bought the 1lb ages ago and still have it, though I haven't been baking a lot like I used to.
