Vitamin B, Vitamin C, and Diabetes

Two of the best natural remedies for diabetes are B-complex vitamins and vitamin C.

B-complex vitamins, particularly B6 and B12, are vital for the health of people who have diabetes. That’s because these vitamins support nerve health, which is critical when addressing conditions such as diabetic neuropathy.

Biotin is another B-complex vitamin that is necessary for cell growth and for the metabolism of protein, fats, and carbohydrates. This vitamin also also been shown to lower fasting blood sugar levels and reduce risk of complications such as diabetic neuropathy.

The ideal daily dose for people living with diabetes is 75-125 mg of B6, 150-1,000 mcg of B12, and 300 mcg of biotin daily.


Vitamin C is a potent antioxidant that protects against free-radical damage throughout the body. This vitamin is also required for the production of collagen, so it strengthens the blood vessels and supports healthy blood flow. In addition, it is involved in multiple aspects of the immune response and boosts overall immunity.

Perhaps most important to people managing diabetes, however, is vitamin C’s ability to lower levels of sorbitol, a sugar alcohol that can collect in the cells and damage the eyes, kidneys, and nerves. This, plus its ability to put the brakes on free radicals, makes vitamin C an important weapon in the arsenal against diabetes complications.

Finally, vitamin C is an excellent therapy for another condition that often co-exists in individuals living with diabetes: hypertension. Irish researchers found that just 500 mg of vitamin C a day lowered blood pressure and arterial stiffness in patients with type 2 diabetes.

I recommend people dealing with diabetes take at least 1,000 mg of supplemental vitamin C daily.
