BPT: I bought a few boxes in Pathmark and /or Shoprite supermarket of PURE VIA, which is pure stevia with an OU hechsher. There are 40 sachets in a box. It is ditributed by Whole Earth Sweetner Co. LLC, Chicago, IL 60602 Tel: 1 800 824 2334 Hope this helps.
Stevia is much more healthier than Splenda/Equal. There are no side effects, and stevia is sweeter than Splenda /Equal / Xylitol.
The cakes baked with Xylitol, are not the same as baked with stevia. The cakes/cookies come out much nicer with stevia than with Xylitol.
I was suffering with terrible pain/aches in my hips/bones with splenda/equal but not with stevia.
Behatlacha!
