Beet root
Sources:
Beetroot may support endurance performance and cardiovascular health through its nitrate and arginine content.
- Nitrates and nitric oxide: Beetroot products can increase nitric oxide, which widens blood vessels and supports blood flow and nutrient delivery; reported performance benefits are most relevant to moderate-to-long-duration endurance exercise.
- Non-stimulant option: Beetroot is described as a non-stimulant performance aid, making it an option when caffeine could interfere with sleep.
- Arginine and heart health: Beets contain arginine, which can influence blood-vessel dilation and blood supply; this gives the nutrient a relationship to heart health.
- Food shape: There is no scientific basis for assuming a food benefits an organ because the food resembles that organ.
