First, I'll give my standard I am not a doc intro. So if you feel what I say pertains to your health then talk to a medical professional or second opinion if you like.

Now onto the topic at hand, B vitamins are water soluble and if you take a little too much you flush them from the body. B vitamins are very fragile as even sunlight breaks them down. I have read where you get LESS than 5% of what you take in B vitamins because the rest is destroyed by your stomach acids and enzymes before it can be absorbed into your blood.

If you look at the USDA requirements for B6 which is 100mg/d and Vitamin E is 1,000 mg/d your not taking too much of these vitamins. (See USDA's URL below). I think I would ask your doctor where HE (SHE) is getting their information. BTW What do YOUR blood levels of these vitamins score as? I think if I was your doc and was concerned with these levels I would have gotten a test to determine where you fall in that range. I would get a copy of these tests to keep at home. Find out what % you are in the population. If the range is 1-100 and you are 2..well you might not be in the bottom 2.5% of the population and treated but you are close to it and should look at getting your numbers up.

I mean do you wait until ALL your oil is gone before you add more. Heck when you are 1 quart low do you wait to add more? NO, because who wants to do permanent damage to your engine..no one. So why wait to do permanent damage to your body because it's raw materials are too low?

The USDA's requirements for vitamins is below:

The above table was found on the USDA's webpage http://fnic.nal.usda.gov/nal_display/index.php?info_center=4&tax_level=3&tax_subject=256&topic_id=1342&level3_id=5140

Good luck working with your doc to find things that help you,

Sidenote.
I have read too LITTLE B vitamins (B6, B9, B12, etc) can cause neuropathy as does too much sugar. Then again sugar glycerates B vitamins (makes them useless to your body) and turns your good HDL fat into bad LDL fat.

If you want to reduce neuropathy then look at reducing your sugar / simple carb intake and increase good fats (olive oil or fish oil) as well as make sure your B vitamins are at healthy ranges (not low "normal" ranges).

Research on B vitamins

"When peripheral nerve fibers are hypersensitive from nerve injury due to viral infection, in addition to the drug therapy for infection, use of Vitamin B1 25 mg., 2 times a day for an average adult often accelerates recovery time."

Because I know a few people out here are diabetics and I brought up how SUGAR can contribute to neuropathy I think I should also mention this article on the Diabetic medication called Metformin and how those on this medication should have B vitamins looked at periodically.

Diabetics on Metformin should watch vitamin B12 levels
http://www.mywesttexas.com/life/article_2d6d7a8f-de0d-56ef-a16e-af261417cfb3.html

"Low vitamin B12 levels are well known to cause problems with the nervous system. One very common complication many diabetics suffer is called diabetic neuropathy. Symptoms range from numbness and tingling of the hands and feet, to stabbing, burning sensations in the arms and legs. Given the role low vitamin B12 levels play in damaging the nervous system, this could make a bad situation worse in diabetics taking metformin on a long term basis.

Another finding from this recent study was metformin using diabetics not only may have lower vitamin B12 levels, but higher levels of another chemical called homocysteine and lower levels of folate(B9). When the levels of these two substances are altered in such a way, it further increases risk of heart disease.

In addition to diabetics on metformin, there are four other situations where vitamin B12 deficiency is more likely to occur. The first is after gastric bypass procedures, which now are being done frequently across the country.

The second is in older adults with loss of stomach acid production, called atrophic gastritis.

Prolonged use of medications called PPIs (such as Prilosec, Prevacid, Nexium and Protonix) for reflux and stomach ulcers will result in poor vitamin B12 (and calcium) absorption from the gut.
Finally, vegans are at higher risk of vitamin B12 deficiency unless they supplement properly.

No one should stop a diabetes medication without first conferring with your doctor, but anyone on metformin should discuss getting a vitamin B12 level checked when starting metformin and getting levels checked periodically."

Thanks so much for sharing your wisdom!!
