Question:
I read on your website that some B-12 vitamins can cause diarrhea due to added sugar substitutes like sorbitol. I have had diarrhea and never thought it could be caused by my vitamin B-12 supplement, until I read your article and stopped taking the supplement. My diarrhea stopped immediately. Can you help me find a brand of B-12 that doesn't contain sorbitol or sugar substitutes that could cause this problem?

Answer:
It's true that in order to taste good, some B-12 supplements (such as dissolvable tablets, liquids, and sprays) contain sugar substitutes which can cause gas, bloating, and diarrhea, as discussed in the B-12 section of the B Vitamins Review.

If you want to avoid these ingredients, you can check and compare the complete list of ingredients for each product, or see CL's Top Picks among B-12 supplements, where there are specific product suggestions, including those which don't contain gas-causing ingredients.

Xylitol is less likely to cause diarrhea. I have IBS and can tolerate small amounts but can't tolerate sorbitol at all.
Bluebonnet has a chewable B12 with only a little sugar as an alternative

As regards liquid subliqual formulas, I have always wondered what else is in the formula - to give it its sweet taste and bright red color, etc.
