This study is paired with ACTRN12623000592640 as it is investigating the maternal-fetal transfer of broccoli sprout supplements. This study is looking at the placental transfer of broccoli sprout and metabolites where as the other study is looking at the pharmacokinetic curve in pregnant participants.

Description of intervention(s) / exposure
Two capsules of broccoli sprout extract GeneActiv Formulation E by Cell-Logic (1400mg)
Total sulforaphane dose 21mg

Two doses per trial participant

Dose 1 - At least 2 hours prior to planned elective caesarean section

Bio-availability
Statistical methods / analysis
A convenience n-number of 8 has been used based on previous work investigating sulforaphane concentrations in pregnant individuals. Demographics will be reported as median and IOR (25th to 75th centile). Paired t-test will be used if normally distributed pharmacokinetic outcomes to determine statistical significance (p < 0.05). Time to maximum concentration (T max) is presented as median and range and tested with Wilcoxon rank-sum test.

Summary
Brief summary
Broccoli sprout extracts contain glucurophanin which converts into a compound called sulforaphane. Sulforaphane is a natural inducer of nuclear related ECH-like related factor 2 (Nrf2) activity which promotes production of endogenous anti-oxidant enzymes and anti-inflammatory cytokines. Numerous disorders of pregnancy result in states of oxidative stress and inflammation including fetal growth restriction and preeclampsia with risks of resultant neuroinflammation on the fetus and possibly adverse neurodevelopment. This study aims to investigate the possibility of sulforaphane transfer via the placenta and in expressed breast milk.
