I am saying that optimum D3 levels have increased my ability to produce glutathione, but failed in the absence of the right nutrients to eliminate the toxins.

Diabetic toxicity is the inability to absorb enough nutrients for complete detoxification. Dolomite via the oral route and calcium Bentonite or any other kind of Bentonite via footbaths is the right way to start gentle detoxification, and olive oil on the feet and orally - let it sit with rosmary and garlic overnight, and then drink it slowly with a blend of FRESH acidic fruit juice.

Iodine involves relaxing the muscles and allowing the detoxification organs at the intestinal track to move material through. Diabetic neuropathy is a form of consistently-flowing heavy metals that the body cannot eliminate.

This state of the body induces an inability to digest protiens, and probiotics allow this to take place- digestive enzymes are the way to go. (fruit sort). Meat and fat intake is vital for the body systems to be able to work in harmony, pineapple juice is vital to the digestion of protiens, fats to the rejuvination of neurons. Without protien, you can't keep up the new cellmaking that vitamin D induces.

Vitamin D3 also induces aptosis, so be cautious.
Go for optimum levels, eliminate multivitamins entirely, and rely upon colloidal minerals, the dolomite and a varied, fresh diet to replace them. Try to use Epsom Salts as much as possible, and go for these cofactors:

Low intake of A (food only)
Magnesium citrate or footbaths often in Epsom Salts
Very light intake of zinc (stop if it produces thyroid swelling)
Potassium from bananas and potatoes, fresh
vitamin k2 from yogurt, homemmade apple cider vinegar (the bottled stuff kills the probiotics in it), and live cheeses like brie and gorgonzola
boron from fresh apples daily

Blessings,
