Alpha-lipoic acid (ALA), a naturally occurring short-chain fatty acid, serves as an essential co-factor in mitochondrial energy production. It is also a potent anti-inflammatory, antioxidant, and free radical scavenger.
While the human body can synthesize a small amount of ALA, it is also found in dietary sources such as vegetables (spinach, broccoli, tomatoes) and meat, primarily in organ meats. In the United States and Europe, ALA is commonly used as a non-prescription dietary antioxidant supplement.
Alpha-lipoic acid achieves weight control through the following three mechanisms:
.
Enhancing Insulin Sensitivity: ALA can improve insulin sensitivity and reduce insulin resistance, helping to lower fasting blood glucose levels. Insulin, a growth hormone, is responsible for cell growth, especially in fat cells. Elevated insulin levels, known as insulin resistance, can lead to weight gain and various chronic diseases. ALA aids in reversing insulin resistance, which is crucial for long-term weight management.
Increasing Cellular Energy Production: ALA influences mitochondrial enzymes, boosting metabolism and energy production. It activates a protein kinase in the hypothalamus, leading to decreased plasma glucose levels, increased insulin sensitivity, and reduced fat accumulation. Supplementing with ALA can elevate metabolic energy levels, enhance mental clarity, promote muscle mass, and further improve overall metabolism. Conversely, low levels of ALA may slow down mitochondrial energy production, resulting in subjective fatigue or decreased metabolic energy.
Reducing Inflammation: Due to its dual solubility in water and fat, ALA possesses antioxidant properties in both cell membranes and cytoplasm, surpassing the efficacy of other antioxidants such as vitamins E and C. Studies indicate that ALA can help reduce inflammation in the body. Elevated inflammation not only impacts hormone levels but also leads to inflammation in fat cells.
Inflammation within fat cells is significant for the following reasons
- Fat cells are not just storage depots; they also transmit hormonal signals to the brain, instructing it to burn fat and increase metabolism.
- High levels of inflammation disrupt these hormonal signals and contribute to leptin resistance, a major obstacle to weight loss.
- Besides affecting fat cell behavior, excessive inflammation can also cause thyroid function issues. Optimal thyroid function is essential for weight management, as thyroid hormones play a significant role in metabolism and energy production.
ALA can help reduce inflammation in the body, potentially alleviating inflammation in fat cells and improving thyroid function to aid in weight loss.
Additional Health Benefits of Alpha-Lipoic Acid: In addition to its role in metabolism and weight reduction, ALA has been shown to improve metabolic disorders, neurodegeneration, rheumatoid arthritis, and diabetes. It may also promote energy production, lower eye pressure, and reduce the risk of cataracts.
Recommended Dosage
Most clinical trials report that ALA is safe and well-tolerated, with a recommended daily dose of up to 1200 mg. For daily maintenance purposes related to weight control, a daily intake of 240 mg is suggested. The bioavailability of ALA does not exceed 40% and decreases with food intake. Therefore, it should be taken on an empty stomach, 30 minutes before meals.
