"Patients with uncontrolled type 2 Diabetes almost always have a severe Glutathione deficiency. Glutathione is not only important for Diabetics to supplement, it is vital for a long and healthy life regardless of your health situation."

"Diabetics have high levels of oxidative stress, which basically means too many free radicals and not enough antioxidants to neutralize them.
Diabetics also have low levels of intracellular glutathione (GSH).
The high levels of oxidative stress and the low glutathione (GSH) levels further complicates the diabetic state which leads to even higher levels of oxidative stress and even lower levels of GSH."
