Depletes Vitamin B1. This medication is commonly used for Contraception
Studies suggest a potential for mild thiamine (vitamin B1) deficiency with long-term use of Oral Contraceptives (OCs). One finding showed that red blood cell activity of an enzyme dependent on thiamine (transketolase) decreased during OC treatment. This decrease indicates that the cells might not have enough thiamine to function optimally, suggesting a mild thiamine deficiency induced by the contraceptives. Supplementation with thiamine (vitamin B1) should be considered for women using OCs.

Vitamin B1 Thiamine — 10 mg
Low or deficient vitamin B12 status elevates homocysteine levels by impairing its conversion to methionine, a process that requires B12 as a cofactor. This hyperhomocysteinemia is linked to increased cardiovascular risks, including atherosclerosis, heart disease, and stroke, through vascular inflammation and endothelial damage. Additionally, low B12 contributes to metabolic disturbances like insulin resistance and type 2 diabetes risk, compounding heart health concerns in susceptible individuals.
Low or depleted vitamin B12 status is linked to reduced bone mineral density (BMD), increasing osteoporosis risk in both men and women. Individuals with low B12 show significantly lower BMD at key sites like the hip and spine compared to those with adequate levels. Routine serum B12 monitoring, alongside periodic bone density scans and supplementation for at-risk groups, helps preserve bone health and mitigate fracture risks.
