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 Depression.

Some side effects may be linked to nutrient depletion caused by this medication.
Research suggests that folic acid supplementation can significantly improve the effectiveness of SSRI medications such as fluoxetine (commonly known as Prozac). This benefit seems to be linked to lowering blood levels of homocysteine, an amino acid. Elevated homocysteine levels have been associated with depression. Supplementing with sufficient folic acid may help the body regulate homocysteine levels, potentially creating a more favorable environment for antidepressants to work effectively.
Research suggests the trace mineral chromium may offer some benefits for people experiencing depression, particularly those with atypical depression. Atypical depression is characterized by symptoms like increased appetite, carbohydrate cravings, and weight gain, alongside feelings of sadness and low mood. Studies show chromium supplementation might improve these specific symptoms in people with atypical depression who also have strong carbohydrate cravings. The potential explanation lies in chromium's possible effects on insulin utilization and brain chemicals like serotonin and norepinephrine, both of which are involved in mood regulation. Supplementation with chromium is suggested to support mood and help protect against depression.
