What is Alpha Lipoic Acid？
Alpha Lipoic Acid is an organic compound and a powerful antioxidant found naturally in the human body. While the body can synthesize it naturally, its ability to synthesize it decreases with age, necessitating its acquisition through food or supplements. For the average person, supplemental Alpha Lipoic Acid is not necessary; it can be obtained naturally through foods like spinach, broccoli, and organ meats. The Alpha Lipoic Acid raw materials provided by Highassay are not only used in dietary supplements but are also utilized in various fields, such as medicine, cosmetics, and biotechnology.
Benefits of Alpha Lipoic Acid
- Because Alpha Lipoic Acid is both fat-soluble and water-soluble, it reaches all parts of the body after absorption, improving its absorption efficiency. It plays a significant role in energy metabolism, neuroprotection, and anti-aging.
- Alpha Lipoic acid is a coenzyme found in mitochondria and a versatile antioxidant and anti-inflammatory agent, similar to vitamins.
- Alpha Lipoic acid helps improve neuropathy by scavenging free radicals, protecting mitochondria, and promoting the synthesis of neurotrophic factors.
- As a dietary supplement, Alpha Lipoic Acid is effective for weight loss, liver protection, and cognitive development, and its effects are mild and non-irritating.
- Alpha Lipoic Acid is commonly found in foods, making it easy to obtain the required dose.
