Colesevelam can affect this through 2 different nutrient pathways: Folic Acid, Vitamin D3. This medication is commonly used for High Cholesterol.
Each nutrient below contributes to this impact through a different mechanism.
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.

Vitamin D deficiency has been linked to a higher risk of depression, often showing up as low mood, fatigue, and reduced motivation in both observational and clinical studies. In one interventional study, female patients in particular showed the greatest improvement in their depressive symptoms after three months of vitamin D supplementation. Notably, serum serotonin levels significantly increased from baseline in both male and female patients after supplementation, suggesting a plausible biochemical pathway through which vitamin D may positively influence mood and motivation.

Some side effects may be linked to nutrient depletion caused by this medication.
Bile acid sequestrants work by binding to cholesterol and bile acids in the intestine, unfortunately, they can also bind to folic acid, hindering its uptake into the bloodstream. For individuals taking bile acid sequestrants, supplementing with folic acid may be advisable to prevent or address potential deficiencies.
