Soy is not listed as an ingredient. It contains rice flour as a filler and hypomellose vegan capsule. I chose this one because it had the least added ingredients. No other ingredients are stated on the bottle, but to be absolutely sure contact the manufacturer.

Q: Is the quality/genuineness of this product all based on buyer reviews, or there is some other way to compare one brand against another?

I suppose the only way to compare would be for you to buy different brands and try them. However, I have found this company’s products to be very good. If you look at the description it is third-party tested. You get 120 capsules which equals 60 servings but it allows the dosage to be split morning and night. The ones I checked have more “other ingredients“ than this company. Right now, I think it’s running 8 cents a capsule and I think that’s a pretty good buy!

Q: Seller or anyone who knows for sure: is this third party tested for heavy metals & arsenic? tia

I can not say for sure about the testing for heavy metals & arsenic. But it does state following...."Third Party Tested: Double Wood's Benfotiamine 300mg is Third Party tested for Potency" as well as "Manufactured and Tested in the USA, Non-GMO, Gluten Free, Vegetarian Safe: DoubleWood's Benfotiamine Capsules are Manufactured and Tested right here in the USA, are Non-GMO, Gluten Free, and safe for Vegetarians" Also I'm just the user of the product maybe reach out to the company itself for more answers. So far I have been very happy with this product.
