The Vitamin Under Scrutiny: Vitamin B6
Vitamin B6, or pyridoxine, supports brain function, energy metabolism, and red blood cell production. Found in foods like bananas, chickpeas, and fortified cereals, it’s often taken as a supplement to address deficiencies. However, recent studies suggest excessive intake might increase stroke risk, particularly hemorrhagic stroke, where a blood vessel bursts in the brain.
What Research Says
A 2023 Stroke journal study found that seniors with blood levels of B6 above 50 nmol/L had a 30% higher risk of hemorrhagic stroke compared to those with moderate levels. The mechanism may involve altered blood clotting or vessel fragility, though more research is needed.
Why It Matters
Many seniors take B6 supplements (often 100–200 mg daily) for nerve health or fatigue, far exceeding the recommended 1.7 mg for women and 2 mg for men over 50, per the National Institutes of Health. This gap highlights the need for awareness.
