Beets
vegetable · Mediterranean and Eastern European folk medicineBeets are rich in dietary nitrates that the body converts to nitric oxide — gently relaxing blood vessel walls and supporting endothelial health. Betalains are powerful liver-supporting antioxidants. The deep red color signals high anthocyanin content.
Preparation: Juice raw for full nitrate availability. Roast for a sweeter, gentler effect.
Pomegranate

Hibiscus
herb · West African, Caribbean, and Mediterranean tea traditionsHibiscus has documented blood-pressure-lowering effects comparable to some pharmaceutical agents. Its anthocyanins also support vascular elasticity.
Dosage: Tea: 1–2 tsp dried calyces steeped 10 minutes, 1–3 cups daily.
