Foundational, Multi-tasking Sulforaphane

Dear Friends

GS Photo JPEGBroccoli sprouts provide an exceptionally rich source of sulforaphane – a potent inducer of enzymes that protect against chemical carcinogens.  In fact, three-day-old sprouts of broccoli contain 10-100 times higher levels of glucoraphanin (the glucosinolate of sulforaphane) than do the mature broccoli plants.  Broccoli sprouts are the richest natural source for sulforaphanes, and the BioImmersion organic broccoli sprouts selected for the Glucosinolate & Sulforaphane are at the 100 fold level.

Our Glucosinolate & Sulforaphane replaces the Cruciferous Sprout Complex as it supplies 6-8 times the potency of the most important phytochemical, sulforaphane.

Glucosinolate & Sulforaphane comes in two sizes: the 120 capsule size as shown to the right and is in stock now, and the 60 capsule size bottle that will be available in three weeks.  With a dose being 1-2 capsules a day, the larger bottle will give a 2-4 month supply.

Food Science

Broccoli sprouts are a rich source of glucosinolates and isothiocyanates, shown in research to induce phase 2 detoxication enzymes, boost antioxidant status, and protect animals against chemically induced cancer.  Glucosinolates are hydrolyzed by myrosinase (an enzyme found in plants and bowel microflora) to form isothiocyanates.  Glucosinolates are inert as phase 2 enzyme inducers and must be hydrolyzed (break-down) to generate the active isothiocyanates (Shapiro et al., 2001).

Sulforaphane (SFN) is a compound derived from cruciferous vegetables with numerous bioactivities (Su et al., 2018). In fact, Broccoli and especially broccoli sprouts, accumulate significant amounts of the phytonutrient glucoraphanin, which is metabolized in vivo to the biologically active sulforaphane (SFN).  The preponderance of evidence available from in vitro, animal and human studies supports the association of sulforaphane with phase II enzyme induction (James et al., 2012), moreover, SFN strongly displays both anticarcinogenic and anticancer activity by modulating ‘key signaling pathways and genes involved in the induction of apoptosis, cell cycle arrest, and inhibition of angiogenesis’ (Su et al., 2018; see also Peng et al., 2015; Zhang & Tang, 2007).

SFN also upregulates a series of cytoprotective genes by activating nuclear factor erythroid-2- (NF-E2-) related factor 2 (Nrf2), a critical transcription factor activated in response to oxidative stress; Nrf2 activation is also involved in the cancer-preventive effects of SFN (Peng et al., 2015).

Sulforaphane is found in research to have many different health benefits:  Alzheimer’s (Kim et al., 2013), Cardiovascular Disorders (Angeloni et al., 2009), Diabetes (Bahadoran et al., 2012), Asthma- upper airway congestion, (Riedl et al., 2009) and Detoxification in all cells, and in particular with Liver Phase II detoxification enhancement (Riedl et al., 2009).

Sulforaphane (SFN) has been demonstrated to be an effective chemopreventive agent for many years (Shapiro et al., 2001), with positive effects against different kinds of cancers, such as cervical (Chen et al., 2016; Abdull et al., 2013), breast (Peng et al., 2015; Li et al., 2010), bladder (Leone et al., 2017), renal cell carcinoma (Juengel et al., 2016), non-small-cell lung cancer (Wang et al., 2017), and colon and prostate cancers (Clarke et al., 2008; Abdull et al., 2013).

We will continue to examine the research on this important food in the next few weeks.
