Higher Copper, Manganese, and Vitamin B12 Levels in Pregnancy Linked to Lower Hypertension Risk in Midlife

A study presented at the American Heart Association’s 2025 Scientific Sessions suggests that higher levels of copper, manganese, and vitamin B12 during pregnancy may reduce the risk of high blood pressure in midlife.

Key Findings:

• Copper & Manganese: Doubling blood levels lowered hypertension risk by 25% and 20%, respectively.
• Vitamin B12: Higher levels led to lower blood pressure nearly 20 years later.
• Combined Effect: A mix of copper, manganese, selenium, and zinc was linked to lower blood pressure.

Study Details:

• 493 women from Project Viva (1999–2021) were analyzed.
• Blood samples from pregnancy were compared to midlife blood pressure (age 51).

Why It Matters:Optimizing prenatal nutrition may provide long-term heart health benefits, highlighting pregnancy as a key window for future cardiovascular risk reduction.
