In some adults, chronic folate deficiency has been linked to neurological manifestations such as peripheral neuropathy, gait disturbance, and subtle to more overt cognitive impairment, especially in older age. Cohort studies have reported that low serum or red cell folate, and elevated homocysteine, correlate with worse performance on memory and executive‑function tests, and may be associated with increased risk of vascular dementia. The encouraging aspect is that, when folate deficiency is identified early and corrected alongside vitamin B12 when needed, some patients experience improvement in neuropathic symptoms and stabilization or modest gains in cognitive performance, particularly when other vascular risk factors are also addressed. 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.
