Alpha-lipoic acid (ALA) is used in the body to break down carbohydrates and to make energy for the other organs in the body.
This powerful antioxidant has been used to treat diabetic neuropathy.
You can get it as a supplement, though in some cases it is also given via IV. A normal dose is 600-1,200mg per day.
Some foods contain little amounts of ALA, including liver, red meat, brewer’s yeast, spinach, broccoli, and Brussels sprouts.
Studies show that taking this supplement can help with pain, and may even reduce blood sugar levels.
N-acetyl cysteine (NAC) is the supplement form of cysteine, an amino acid and antioxidant.
While NAC is not available in food, cysteine is present in foods with a high amount of protein, such as pork, beef, chicken, fish, lentils, oatmeal, eggs, low-fat yogurt, sunflower seeds, and cheese.
Some preliminary studies show that NAC can help reduce neuropathic pain, improve coordination, and remove damage from oxidative stress.
