Oral contraceptives and changes in nutritional requirements

Area of Science:

• Nutritional Science
• Pharmacology
• Women's Health

Background:

• Oral contraceptives (OCs) are widely used by women, impacting physiological processes.
• Research indicates OCs influence nutritional needs and can lead to specific nutrient depletions.
• The World Health Organization highlights the clinical relevance of OC's effect on nutrient requirements.

Purpose of the Study:

• To investigate the impact of oral contraceptives on vitamin and mineral requirements.
• To identify key nutrients that may be depleted in women using OCs.
• To explore the role of dietary supplements in preventing nutrient deficiencies in OC users.

Main Methods:

• Review of existing research on oral contraceptives and nutrient levels.
• Analysis of studies comparing nutrient status in OC users versus non-users.
• Consideration of factors contributing to deficiencies, such as diet and malabsorption.

Main Results:

• Key nutrient depletions associated with OC use include folic acid, vitamins B2, B6, B12, C, E, and minerals magnesium, selenium, and zinc.
• Blood levels of these nutrients are often lower in women taking OCs.
• Inadequate diet, lifestyle, and malabsorption can exacerbate deficiencies.

Conclusions:

• Women using oral contraceptives may have increased requirements for specific vitamins and minerals.
• Dietary supplementation should be considered a primary strategy to prevent and manage nutrient deficiencies in this population.
• Clinicians should proactively address potential nutritional impacts of OC use.
