In the brain, vitamin B6 (pyridoxine) is a cofactor for enzymes that make key neurotransmitters such as serotonin, dopamine, and GABA, so low B6 status can contribute to depressive symptoms, irritability, and increased stress sensitivity. Epidemiologic studies in older adults and other populations have found that low plasma pyridoxal‑5‑phosphate (the active B6 form) or lower dietary B6 intake is associated with higher depression scores and roughly doubled odds of having clinically significant depressive symptomatology. The encouraging finding from emerging trials is that, in people with low or marginal B6 status, supplementation can modestly improve measures of anxiety and depressed mood, especially when used as part of a broader treatment plan that also addresses sleep, stress, and other nutrient deficiencies. This medication is commonly used for Contraception.

Some side effects may be linked to nutrient depletion caused by this medication.
Research suggests that oral contraceptives (OCs) may play a role in vitamin B6 deficiency. A deficiency is concerning because vitamin B6 plays a crucial role in mood regulation and blood sugar control. Some women using OCs experience symptoms like depression and impaired glucose tolerance, which could potentially be linked to this vitamin B6 deficiency. Low vitamin B6 levels are independently associated with an increased risk of blood clots in both arteries and veins (venous and arterial thromboembolism, or TE). This association suggests that the B6 deficiency caused by OCs might partly explain the higher risk of TE observed in women using birth control pills. This highlights the importance of ensuring adequate vitamin B6 intake for women on OCs and therefore supplementation should be considered.
Studies suggest that women using oral contraceptives might have lower levels of vitamin C within their white blood cells (leukocytes) and platelets. This depletion could be linked to reduced activity of antioxidant enzymes like glutathione peroxidase (GPx) and glutathione reductase (GR) in the blood. These enzymes play a role in protecting cells from damage. Research also shows that supplementing with vitamin C, alongside vitamin E, can significantly increase the activity of these antioxidant enzymes in women taking OCs. This suggests that vitamin C supplementation might be beneficial for women on birth control pills.
Studies suggest that oral contraceptives (OCs) may contribute to zinc deficiency. Research has shown a significant decrease in serum zinc levels, the zinc circulating in the blood, in women taking OCs. This decrease is thought to be due to potential changes in how the body absorbs, excretes, or utilizes zinc within tissues. Due to its vital role in many bodily functions, ensuring sufficient zinc intake through supplementation should be considered for women on birth control pills.
Oral contraceptives (OCs) have been linked to a decrease in Vitamin B12 levels. Studies have shown a significant reduction in serum B12, the vitamin circulating in the blood, in women taking OCs for extended periods. One US study found a 40% decrease in B12 levels after five years of OC use. This decrease is concerning because vitamin B12 plays a crucial role in converting a form of folate (N-methyltetrahydrofolic acid) into its active form (tetrahydrofolic acid). This active folate is essential for healthy red blood cell production and other bodily functions. Due to the vital role of vitamin B12, supplementation when using OCs long-term should be considered.
When using oral contraceptives (OCs), the body might experience increased oxidative stress due to hormonal changes. Vitamin E, a potent antioxidant, could potentially help counteract this stress and promote cellular health. Research shows that combining vitamin E with vitamin C supplementation might be even more beneficial. Studies like one where Group C received both vitamins showed a significant increase in the activity of enzymes (GPx and GR) crucial for antioxidant defense, along with a reduction in markers of oxidative damage (plasma MDA levels). This suggests that a combined approach with vitamins E and C might offer enhanced protection against cellular stress for women using OCs.
Women using Oral Contraceptives (OCs) may benefit from including vitamin B2 (riboflavin) in their regimen. Vitamin B2 plays a critical role in activating other B vitamins, like folic acid and B6, which are essential for various bodily functions. Studies have shown that women on OCs have lower levels of active vitamin B2, as measured by the activity of an enzyme dependent on it (glutathione reductase). These reduced levels might be linked to migraines, a frequent side effect of OCs that can sometimes lead women to discontinue the medication. By ensuring adequate B2 intake, women on OCs may potentially experience reduced migraine frequency and benefit from the proper activation of other B vitamins.
Women using oral contraceptives (OCs) may experience mood changes, including depression. Research suggests a potential link between these emotional shifts and a decrease in brain levels of the neurotransmitter norepinephrine (noradrenaline). This decrease could be related to reduced availability of its precursor molecule, tyrosine, in the brain. Studies have shown a significant decline in tyrosine levels in women on OCs. One study found that the area under the curve (AUC) in plasma for tyrosine in OC users were 43% of control levels. Tyrosine supplementation could potentially help regulate mood and improve emotional well-being while taking OCs.
