## Questions & Answers

**Q: How many grams of sweetener?**
A: Sorbitol is listed under other ingredients. There is no specification as to grams.

**Q: Does it contain magnesium as well**
A: This product contains magnesium stearate.

**Q: I can not find any research on this particular B1. Does anyone have any more information about it?**
A: Not really.  All I can say is that other B1 tablets make me sick. I can't stand the smell or taste, and I taste them all day and smell them in my skin.  So gross! They are much higher dosage though. This claims to work better because it is "coenzymated".  I have low levels of B1 and when I take this supplement, my levels came back up.  I stopped taking it for awhile and my levels were down too low again 3 months ago. I restarted it and on repeat blood work, after taking 2 tabs of this a day, my levels are back in normal range now.

**Q: how long after expiration date can I use this???**
A: Thanks for your question. Currently, the Source Naturals Coenzymated B-1 product does come with a “Best If Used By” date, which can be located on the underside of the bottle. Source Naturals "Best if Used By" dates reflect the date which we guarantee the potency of the product. Once any product passes its best if used by date, we can no longer guarantee the potency or efficacy of the product. Additionally, due to insufficient evidence regarding safety of using a product passed the best if used by date, we suggest you contact a healthcare professional, including a physician, pharmacist, or naturopath, prior to using this product to ensure safety based on your individual biochemistry.

### ⭐⭐⭐⭐⭐ Well tolerated B-1 tablets!
*by H***C on September 22, 2016*

My doctor prescribed B-1 as I seem to be deficient. However, the pills from the pharmacy have a horrible taste that I would burp up and taste for a long time, making me feel very sick to my stomach. These B-1 Sublingual pills are a lower dosage than what the doctor prescribed, but their flavor is sort of minty and they do not bother my stomach. If you need B1 and have problems getting it down, I recommend you give these sublingual pills a try.
