Can alpha lipoic acid relieve pain?

Alpha lipoic acid is one of the over-the-counter agents that may have benefits for neuropathic pain according to Sean Mackey, the Chief of Pain Medicine at Stanford University, who appeared on the Huberman Lab. It is believed to work as a free radical scavenger and modulates T-type calcium channels found in nerves, which can help reduce neuropathic pain. It is generally well-tolerated and taken by people for a general sense of well-being, although it can cause some stomach upset. It's worth noting that Andrew Huberman highlighted Dr. Mackey's mention that alpha lipoic acid may affect heart rate during high-intensity interval training due to its effect on calcium channels in the heart, as experienced by Dr. Mackey himself 1.
