Brief summary
Sulforaphane is a naturally occurring organophosphur able to upregulate phase II detoxification enzymes resulting in anti-inflammatory and antioxidant effects. Sulforaphane has been widely investigated outside of pregnancy in a wide variety of clinical trials including cancer, autism spectrum disorder and gastroesophageal reflux disease. Sulforaphane is generally administered in the form of glucurophanin via broccoli sprout supplements and has variable formulations and manufacturing pathways. It is hypothesised that sulforaphane will provide beneficial effects to various pathological states of pregnancy. It is important to compare the various formulations of sulforaphane commercially available to inform decisions for clinical trial design and analysis of sulforaphane trial outcomes. This study will compare three different commerically available broccoli sprout extracts and their circulating concentrations in healthy pregnant participants.
Interventions
Three different commercially available broccoli sprout extracts will be compared for their circulating concentration of sulforaphane. Participants will be enrolled into groups sequentially until allocation exhausted. Participants will be allocated to group 1 first, group 2 second and group 3 third. Each participant provided a single dose from one of the three different extracts Group 1 - two capsules (total dose - 500mg) stabilized sulforaphane formulation BROQ - total sulforaphane dose 26.1mg Group 2 - two capsules (1400mg) broccoli sprout supplement GeneActiv Formulation E by Cell-Logic - total sulforaphane dose 21mg Group 3 - four capsules (1760g) broccoli sprout supplement AVMACOL® Regular Strength - total sulforaphane dose 21.8mg
