What is alpha-lipoic acid?
ALA, also known as alpha-lipoic acid, is an organic-chemical compound from the group of saturated fatty acids. This compound, also known as thio-octanoic acid, exhibits good solubility in fats and plant glycol and lesser solubility in water. In the human body, it is associated with two fundamental functions. ALA is a powerful antioxidant, which is of critical importance to our metabolism. Eliminating a significant amount of free radicals is an effective method for detoxifying the entire organism and restoring its balance. Furthermore, alpha-lipoic acid is one of the substances responsible for converting ingested food into energy. Although it is produced in the human body, additional support in the form of supplementation is necessary to maintain its antioxidant properties.
The action of Alpha-lipoic acid
The precise mechanism of action of Alpha-lipoic acid is somewhat more complex. In this case, it is also a very potent antioxidant that primarily relies on the elimination of harmful free radicals. It contributes to a series of positive changes, such as significantly reducing damage within the neuron acid, preventing the lack of blood transported to the nerves, and inhibiting the aging process of our cells. It also enhances the performance of other antioxidants, particularly vitamins C and E. It has a strong antioxidant effect, but it also has a strong impact on the effectiveness of vitamins C and E. It connects with the effectiveness of ALA by increasing the realization of the toxic acid in the neuron column. It leads to a significant effect of nearby amino acids, which not only function as a strong body but also as an essential toxin in the thyroid.
Dose and performance
The dosage of alpha-lipoic acid is dictated by the purpose for which it is intended to be utilized. In the case of a prophylactic application, a dosage of up to 300 mg of the preparation per day is typically suggested. However, physically active individuals such as athletes, as well as persons living a very intense lifestyle, should consume between 600 and 1200 mg of thioctic acid. Alpha-lipoic acid can be introduced into our body either through dietary supplements or through normal diet. The most valuable sources of this acid are spinach, beef kidneys and hearts, broccoli, potatoes, Brussels sprouts, and peas.
Adverse effects
The supplementation with alpha-lipoic acid has been shown to be extremely safe and does not present any serious risks. Indisputably, improper dosing and excessive use of ALA can lead to skin alterations in the form of rashes or issues with the gastrointestinal tract such as diarrhea, abdominal pain, or vomiting.
