Question:
Anyone have allergy to sublingual B-12 that causes mouth sores under tongue?

I started my B-12 sublingual tablets a week or so ago... ever since then, I have sores under my tongues - little ulcers. My doctor has not heard of this reaction before, but my best friend's doctor told her that if this happened to her - she was probably allergic to it... just wondering if anyone else had this issue or heard about it?? Thanx!    — Denise W. (posted on November 2, 2004)

Hi. I know this sounds wierd but I have the same little white soars. I would change the brand or you might be detoxing. That is what I am doing. I am breaking out and I get those soars. Hope this helps.

Denise- I had a comparable problem when I switched to the GNC brand of sublingual B-12. Because they did not easily dissolved, I found they irritated my tongue. I took about one week off to let the irritation clear up and once I switched back to the Trader Darwin brand (which dissolves very quickly and is available at Trader Joes), I never had the problem again. Good luck.

YES! I just purchased the Rexall brand b-12 and have those sores, I have always used TwinLab brand and never had a problem but can't find them in stores around here so I bought Rexall, tastes nasty and leaves sores. I've ordere Twinlab in the past from Vitalady.com for $11.89/250 dots but found them on Vitacost for $9.26. And they taste so much better and dissolve quicker too.

if you continue to have problems with the subligual, you do have other options, the tablets or shots. I just take tablets (1 250 mg tablet daily) and my b12 levels were high, so now I only take them every other day.
