“Investigators estimated that the global-cognition difference corresponded to about two years of age-related change. Dr. Patrick then turns to sulforaphane, which is formed when myrosinase converts glucoraphanin from cruciferous vegetables.”

“A short study also found changes in selected immune-cell phenotypes and metabolism, extending research into how mitochondrial support may influence cellular function. Sulforaphane is produced from glucoraphanin through the action of myrosinase and activates NRF2-regulated cytoprotective pathways.”

“While broccoli sprouts are rich sources of sulforaphane, supplements containing sulforaphane or its precursor, glucoraphanin, are available. Determining optimal doses and sources of sulforaphane presents challenges due to variations in content and individual metabolism.”

“The abundance of glucoraphanin in broccoli seeds suggests that consuming the seeds (rather than sprouting them) provides a better means of obtaining the end product – sulforaphane.”

“Glucoraphanin can be converted to sulforaphane by the enzyme myrosinase, making enzyme activity an important feature of a formulation. Small human experiments found greater sulforaphane bioavailability from preparations with active plant myrosinase than from glucoraphanin alone.”

“Glucoraphanin is found in certain cruciferous vegetables, including broccoli (especially broccoli sprouts) and red kale. Glucoraphanin is hydrolyzed by the enzyme myrosinase to produce sulforaphane, which demonstrates many beneficial effects in humans.”

“The participants took a glucoraphanin-rich broccoli sprout extract that provided 200 micromoles of glucoraphanin in water. The authors of the study collected urine samples from 8 a.m. to 4 p.m. and from 4 p.m. until 8 a.m. on the following morning.”

“But sulforaphane isn’t normally present in these vegetables. Instead, it’s an end product of a chemical reaction between a precursor molecule (called glucoraphanin) and an enzyme (called myrosinase). The chemical reaction occurs when you chop, chew, or otherwise damage the plant.”

“Dr. Patrick states that she has no affiliation with the named supplement company. Sulforaphane activates NRF2-regulated cellular stress-response pathways. Its precursor, glucoraphanin, depends on myrosinase for conversion, so formulation can strongly affect exposure.”

“Vitamin D is Dr. Patrick's second priority because sun-derived production varies with age, skin pigmentation, latitude, clothing, and sunscreen use. Her third choice, sulforaphane, is formed from glucoraphanin in cruciferous vegetables and activates NRF2-regulated cellular defense pathways.”
