Folate deficiency has been associated with a higher risk of depressive symptoms, irritability, and other mood disturbances, likely through its role in one‑carbon metabolism, monoamine neurotransmitter synthesis, and methylation processes in the brain. Clinical and epidemiologic studies have found that people with low folate or elevated homocysteine are more likely to experience major depression, and lower folate status has been linked to poorer response to certain antidepressant medications. The encouraging clinical point is that, in folate‑deficient individuals, correcting folate status (often with folic acid or methylfolate, and alongside vitamin B12 when indicated) may improve mood symptoms and, in some cases, enhance antidepressant treatment response, especially when combined with comprehensive psychiatric and lifestyle interventions. This medication is commonly used for Pain Management.

Some side effects may be linked to nutrient depletion caused by this medication.
Regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen may decrease your folic acid (folate) levels. This is because NSAIDs can interfere with how your body processes folate. If you take OTC pain relievers regularly, consider folate supplementation to avoid potential deficiencies.
Recent suggests that damage caused by free radicals in tissues plays a role in stomach ulcers (gastric mucosal lesions) caused by nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Based on this, it was investigated whether the amino acid taurine could protect the stomach lining from ibuprofen-induced damage. The study also examined the effects of taurine on the stomach's natural antioxidant defenses, including enzymes like superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX), as well as a molecule called glutathione (GSH). It found that giving taurine orally for three days in a row protected the rats' stomach linings from the ulcers caused by ibuprofen. Additionally, taurine significantly reduced a marker of free radical damage (lipid peroxidation) in the ibuprofen-treated rats.
