The Benfotiamine is the most helpful for the people who cannot tolerate alcohol, or who drink heavily. B1 is the cofactor used in alcohol metabolism and safe clearance from the body. High levels of alcohol are poisonous, and damaging.

Being in jail I would expect poor diet too.
Drinking heavily for a long time, leads to vitamin deficiencies in most people. That is why alcohol withdrawal treatments often include a B-complex.

Benfotiamine is a special better form of B1 thiamine.

My objections are that with the formula you ask about are:
1) they don't instruct you to take on an empty stomach which you should.

2) it is a fixed combo which you cannot change doses of the individual ingredients to meet your own needs.

3) it is expensive. If it works you cannot determine which ingredient is being the most helpful for YOU. Each person is different and you may not need all that is in there.

Most people with alcoholic neuropathies recover after they stop drinking. You have to however, provide a good diet, high in nutrients and antioxidants to see improvements. Eating junk food or high sugar high starch fast food, will not heal you up and provide success. People who are avoiding alcohol because of previous heavy use tend to
crave sugar and carbs...to keep the same blood sugar levels.
Chocolate is often substituted for alcohol. But donuts, and cookies can also be tempting. You have to watch that.
