## Questions & Answers

**Q: Is this benfotiamine**
A: Per the label the ingredients are Thiamine Mononitrate (100mg) and Calcium Carbonate (24mg).  Nothing on the label indicates it includes Benfotiamine!  What follows in FYI - 

I assume you asked the question  due to Benfotiamine being a lab-made version of vitamin B1, also called thiamine. Scientists are studying it to see if it might help conditions like diabetes-related nerve damage, Alzheimer's disease, and alcohol dependence.  Benfotiamine is a relative of thiamine, which is better known as vitamin B1. Thiamine is critical for the metabolism of our brain's major energy source—glucose. Benfotiamine, which converts to thiamine in the body, enters cells more easily than thiamine.  Like disulfide derivatives, benfotiamine may be useful for the treatment of acute peripheral syndromes of thiamine deficiency because it is better absorbed than thiamine, but in contrast to sulbutiamine, it seems to be devoid of specific effects on brain function.

**Q: I heard by taking these it prevents mosquito bites, is this true?**
A: I’m a mosquito magnate.   Decades ago my doctor told me to take B1 to help deter them.   He said it gives your skin an odor that repels them.   I can smell it on my palms after taking B1 for a few days — it smells like aspirin to me.  And it has always helped me.   A few mosquitos will be more determined, but a couple bites I can handle.   40 bites was just crazy.  Anyway.   That is my experience.

**Q: How ling for refund kn canceled order**
A: I don't know.  You will have to ask Amazon about cancels & returns.

**Q: Why is this so affordable? Does it have natural ingredients? Is it easily absorbed?**
A: Pharmavite, the manufacturer of Nature Made vitamins, minerals and nutritional supplements, has been in business for 50 years and is committed to producing the highest quality products while always striving to manage the costs of our products.

The bioavailability of different nutrients can vary for multiple reasons – some are absorbed best in the natural form, while others need newer technology to improve absorption in the gut.

Our Quality Control team performs rigorous testing to all raw materials and the finished product to ensure our products are made to the highest standards, including verification by US Pharmacopeia (USP) – independent verification for potency and purity. Nature Made is the first national brand to be USP verified and will display the USP seal on the label.
