What Are the Side Effects of Alpha-Lipoic Acid?

Alpha-lipoic acid, a type of fatty acid, many help you to prevent cancer, according to the National Cancer Institute. The substance, available in foods such as spinach, potatoes and broccoli, works as an antioxidant to make your cell walls more resistant to free radicals. that might cause cancer. Although alpha-lipoic acid as a supplement has yet to be clinically tested sufficiently, it may help you lower your glucose levels and benefit diabetics. The Food and Drug Administration has not approved alpha-lipoic acid as a medicine, and you should tell your doctor if you intend to take it as a supplement. Side effects may occur.

Hypoglycemia

Supplements of alpha-lipoic acid can reduce glucose or blood sugar levels and cause hypoglycemia. Symptoms include blurred vision, irritability, hunger and feeling faint. For a minor case of hypoglycemia, eat a piece of candy. This may raise your blood sugar levels. If symptoms continue, go to your doctor or the emergency room.

Digestive Problems

Taking alpha-lipoic acid may cause mild stomach upset. This feeling can go away in time. Take alpha-lipoic acid with a meal to lessen the upset. If the problem continues, increases to nausea, check with your doctor.

Fatigue

Alpha-lipoic acid as an oral supplement may make you feel fatigued. These lethargic feelings may relate to lower glucose levels, but does not necessarily indicate you have hypoglycemia. Your body uses sugar ingested, and makes its own glucose from other types of food, to provide energy in your system. Tiredness typically fades as you continue to use the supplement.

Pain

Alpha-lipoic acid might cause spasms or cramps, but they generally are mild. Mild cramping should stop without a doctor's aid. If you experience severe cramps, get medical help.
