Explore 5 suggestions for proven alpha lipoic acid supplements and support your health comprehensively!
Supporting your health should take place on many levels. A well-balanced diet, regular physical activity and the right supplementation are extremely important. It is worth reaching for dietary supplements when we are unable to provide our bodies with effective doses of vitamins, minerals or antioxidants. Alpha lipoic acid belongs to the latter group. Alpha lipoic acid is a broad-spectrum compound that can improve the overall condition of the body and support the body in the fight against many diseases. In the following article, you will find out what the most important properties of alpha lipoic acid are, what diseases it can combat and five suggestions for the best supplements with this valuable ingredient.
Alpha lipoic acid - what is it?
Alpha lipoic acid (ALA, thioctic acid) is a water-soluble and fat-soluble compound that is synthesised by our body. It belongs to the group of saturated fatty acids. Alpha lipoic acid shows the ability to penetrate the blood-brain barrier, so it is able to reach almost every cell in the body. ALA acid persists in the bloodstream for about 30 minutes and is then metabolised in the liver and excreted in the urine. Therefore, its use is safe for health.
Alpha lipoic acid - properties and uses
Alpha lipoic acid is a versatile substance. First and foremost, it has strong antioxidant properties. It fights free radicals, thus protecting cells from damage and slowing down the body's ageing process. In addition, ALA acid shows the ability to regenerate other antioxidants, such as vitamin C and E, which significantly enhances their effects. It regenerates cells and also counteracts pain accompanying e.g. neurological disorders.
ALA acid is also used as an effective support for the treatment of diabetes. It increases glucose tolerance and tissue sensitivity to insulin. It is also recommended for ischaemic heart disease and hypertension. Regular intake of alpha lipoic acid can have a positive effect on the circulatory system by strengthening the elasticity of blood vessel walls. In addition, alpha lipoic acid has anticoagulant and anti-inflammatory effects. It speeds up metabolism, reduces appetite and regulates blood sugar levels.
Other valuable properties of ALA acid include support in the fight against diseases such as asthma, multiple sclerosis and obesity, among others.
Alpha lipoic acid - natural sources
Rich sources of alpha lipoic acid include:
- - spinach,
-
- broccoli,
- - potatoes,
-
- green peas,
- - Brussels sprouts, tomatoes,
- - beef spleen, beef kidney,
-
- beef heart,
- - beef brains,
- - rice bran.
However, it is worth noting that supplying ALA with food is not sufficient to ensure adequate levels in the body. Although the bioavailability of ALA is high, it is still not sufficient to prevent atherosclerosis or lower blood pressure. For this reason, it is worth reaching for dietary supplements containing this ingredient.
Alpha lipoic acid supplements
Alpha lipoic acid supplements are an excellent way of supplementing deficiencies of this valuable component in the daily diet.
Alpha lipoic acid is a compound found in two forms: R-ALA and S-ALA. R-ALA is the naturally occurring form of alpha lipoic acid, which is characterised by higher activity and bioavailability. S-ALA is a synthetic and less active form. Therefore, its first form, R-ALA, should be present in supplements.
ALA acid supplements are mostly available in capsule and tablet form. It is assumed that an effective and safe daily dose of this ingredient is between 300 mg and 600 mg. This is a safe dose of ALA that does not cause side effects. People who regularly engage in physical activity can increase their daily dose by up to twice as much, but it is advisable to consult their individual needs with a doctor. People suffering from inflammation of the nervous system can use doses of approximately 600 mg per day.
Alpha lipoic acid supplements - for whom?
Alpha lipoic acid supplementation can be extremely beneficial for people with various health problems. First of all, it is recommended for people with type 2 diabetes or insulin resistance. This is due to ALA acid's ability to increase tissue sensitivity to insulin and its effect on blood glucose regulation.
ALA acid may also be helpful in reducing the annoying symptoms of diabetic neuropathy, such as pain, tingling and numbness.
As a powerful antioxidant, ALA acid helps to neutralise free radicals and reduce the damage caused by them. Therefore, it can be beneficial for people with heart disease, neurodegenerative diseases (such as Alzheimer's) and the elderly.
Alpha lipoic acid is also indicated for athletes and physically active people. It supports muscle regeneration after exercise and increases energy production, which translates into performance.
People suffering from heart disease will also appreciate the properties of ALA acid. It has an impact on the regulation of total cholesterol levels: it lowers the LDL fraction and raises the 'good' HDL cholesterol. In addition, it protects capillary tightness and reduces lipid oxidation.
However, supplementation with alpha lipoic acid should be avoided by pregnant and breastfeeding women due to the lack of sufficient studies on the effects of this compound on the developing foetus and the health of newborns.
What are the effects of taking alpha lipoic acid supplements?
The most important effects of taking alpha lipoic acid supplements include:
Antioxidant effects - ALA acid is a powerful antioxidant. It exhibits the ability to combat free radicals and inflammation. Due to the fact that alpha lipoic acid is soluble in both water and fat, it has an effect on almost all cells in the body.
Delaying the body's ageing processes - as a powerful antioxidant, ALA acid effectively delays the body's and skin's ageing processes. For this reason, it is also often used in the cosmetic industry.
Supporting the treatment of type 2 diabetes - ALA increases the body's sensitivity to insulin and promotes a reduction in blood sugar levels. It thus reduces the development of diabetic neuropathy and associated pain.
Supporting cardiovascular health - ALA acid increases the elasticity of blood vessels and regulates total cholesterol, which may help prevent atherosclerosis and other heart diseases.
Improved muscle function - alpha lipoic acid speeds up muscle recovery after exercise and increases physical performance.
Benefits
The most important benefits of taking ALA acid supplements include:
- Antioxidant and anti-inflammatory effects.
- Delaying the body's ageing processes.
- Supporting the treatment of diabetes.
- Alleviating the symptoms of diabetic neuropathy.
- Supporting cardiovascular health.

- - abdominal pain,
- - rash.
If the above-mentioned discomforts or any other adverse reactions occur due to supplementation with alpha lipoic acid, a doctor should be consulted.
Alpha lipoic acid may interact with certain medications, e.g. thyroid medications, blood glucose lowering or blood thinners. Therefore, a doctor should be consulted before starting supplementation.
Conversely, when taking alpha lipoic acid for diabetes, blood glucose levels should be monitored regularly.
What should I pay attention to when choosing an alpha lipoic acid supplement?
In order to ensure that the ALA supplement used is as effective as possible, it is worth paying attention to the following criteria when choosing a particular preparation:
Form of alpha lip oic acid - Choose a supplement with alpha lipoic acid in the R-ALA form. This form of acid is more active and better absorbed by the body.
Alpha lipoic acid content - Pay attention to the ALA acid content of the supplement in question. It is assumed that the most effective doses are 300 - 600 mg/day.
Composition - Make sure that the composition of the supplement is simple and that there are no substances in it that could be harmful to health (dyes, preservatives, fillers).
