Alpha lipoic acid: what it is used for, benefits and when to take it
Alpha-lipoic acid (ALA) is a natural compound that the human body produces in small amounts, but it can also be obtained through food and supplements. In recent years, it has gained popularity thanks to its antioxidant, metabolic, and neuroprotective benefits.
If you are wondering what alpha-lipoic acid is used for, here you will find a clear guide to its functions, its most relevant applications, how it is obtained, and when it may be advisable to take it as a supplement.
What is alpha lipoic acid and how does it work in the body?
Alpha lipoic acid is a molecule found in all cells of the body and plays an essential role in cellular energy production. It is a powerful antioxidant that neutralises free radicals and regenerates other antioxidants such as vitamin C, vitamin E and glutathione.
Unlike other antioxidants, ALA is soluble in both water and fat, allowing it to act in different cellular environments, including the nervous system.
In addition to its antioxidant properties, it is also credited with beneficial effects on glucose metabolism, brain health, and the cardiovascular system.
What is alpha-lipoic acid used for? Most well-known and supported uses
Scientific research has identified several important health applications for alpha-lipoic acid. Here are some of the most notable ones:
Glucose control and diabetes support
ALA has been shown to be useful in people with insulin resistance or type 2 diabetes, as it improves glucose uptake by cells. It may also help reduce symptoms of diabetic neuropathy, such as pain or numbness.
Neuroprotection and relief from nerve pain
Thanks to its ability to cross the blood-brain barrier, ALA acts as a protector of the nervous system, helping to reduce inflammation and oxidative stress. It has been used in cases of multiple sclerosis, mild cognitive impairment, and other neurological conditions.
Cellular antioxidant and healthy ageing
Alpha lipoic acid combats cellular damage caused by free radicals, helping to slow down cellular ageing and protect tissues from deterioration. Its antioxidant effect is one of the most powerful known.
Skin health and detoxifying function
In dermatology, ALA has been linked to improved skin texture and elasticity, as well as a reduction in blemishes and wrinkles. It also supports liver function and the elimination of toxins from the body.
Benefits of alpha-lipoic acid for active people and athletes
ALA has also attracted attention in the sports world for its ability to:
-
Reduce muscle damage after intense training sessions.
-
Accelerate recovery by reducing post-exercise inflammation.
-
Support energy metabolism in endurance sports.
Furthermore, by improving insulin sensitivity, it can promote better nutrient utilisation after physical exercise.
In which foods is alpha-lipoic acid found naturally?
Although it is produced naturally by the body, ALA is also found in small amounts in certain foods. Among the foods richest in alpha-lipoic acid are:
-
Spinach
-
Broccoli
-
Potato
-
Red meat (especially liver)
-
Kidneys
-
Brewer's yeast
However, to obtain therapeutic doses with more evident effects, it is often necessary to resort to supplementation.
When is it advisable to take it as a supplement?
Alpha-lipoic acid supplementation may be beneficial in several contexts:
-
People with diabetes or insulin resistance
-
People with symptoms of oxidative stress or chronic inflammation
-
Cases of peripheral neuropathies
-
Individuals seeking to improve their physical performance and recovery
-
Individuals who desire powerful antioxidant support for healthy ageing
The most commonly used doses range from 300 to 600 mg per day, depending on the indication. It is always advisable to consult a professional before starting to take it.
Side effects and precautions of alpha-lipoic acid
Alpha lipoic acid is safe for most people when used in appropriate doses. However, in some cases it may cause mild side effects such as:
-
Nausea
-
Dizziness
-
Headache
-
Gastrointestinal discomfort
Special caution should be exercised in people with diabetes, as ALA may enhance the effect of hypoglycaemic medicines. Its use during pregnancy or breastfeeding without medical supervision is also not recommended.
