Summary
Brief summary
Sulforaphane is a naturally occurring compound found in cruciferous vegetables such as broccoli, and has potent anti-inflammatory and antioxidant effects. Sulforaphane is administered in the form of broccoli sprout supplements as they're cheap, room temperature stable and have a proven safety profile in clinical trials outside of pregnancy including cancer and autism spectrum disorder. This trial will use non-invasive clinical methodologies to assess the vasculature in women both before and after a dose of a broccoli sprout extract. We would like to recruit up to 30 women for this trial (non-pregnant, pregnant, pregnant with hypertension) to assess blood pressure, collect one blood sample, and assess flow mediated dilation. This will assess whether a single dose of a broccoli sprout extract has immediate effects on the vasculature. We hypothesise that a single dose of a broccoli sprout extract will not affect blood pressure but will increase flow-mediated dilation in all non-pregnant and pregnant women.
