The sciatic nerve, the body’s longest, can become irritated from compression, inflammation, or other factors, leading to pain, tingling, or numbness that affects walking, sitting, and sleep. Over time, ongoing irritation may slow natural recovery processes in nerves and surrounding tissues.
Research indicates that deficiencies in key nutrients can influence inflammation, muscle tension, and nerve signaling. For instance, studies have observed higher rates of low vitamin D among people with chronic low back and leg pain, with some reports showing insufficiency or deficiency in a majority of cases. Similar patterns appear with other nutrients that support muscle relaxation and nerve protection. But here’s the encouraging part: correcting these through lifestyle adjustments shows promise in supporting overall comfort, according to various investigations.
But that’s not the full picture—let’s look at the three most researched ones.
Vitamin D: Supporting Nerve and Bone Health
Vitamin D plays a role in regulating inflammation and supporting calcium balance, which affects bones, discs, and nerve tissues. Low levels (often below 20-30 ng/mL) have been linked in studies to greater reports of musculoskeletal discomfort, including in those with low back and radiating leg pain.
