Life Extension's Alpha-Lipoic Acid with Biotin is a synergistic blend, combining the powerful antioxidant properties of ALA (250mg) with a foundational 2500 mcg dose of biotin. This formulation targets both cellular health and beauty support, which is a unique selling point. While ALA is beneficial for general health and can indirectly support skin by combating oxidative stress, the biotin dose is moderate compared to many single-ingredient biotin products. The most significant drawback is its exceptionally high price per serving, which makes it a premium product not easily justified for consumers primarily seeking biotin benefits.
