Research shows that sulforaphane increases the expression of the VDR gene.(6)
In other words, the sulforaphane that we find in cruciferous vegetables and herbs like
wasabi helps the body absorb more vitamin D—improving bone mass, as well as the ability to fight infection, cancer, and inflammation.
Sulforaphane is made when cruciferous vegetables and roots release an enzyme called
myrosinase. This happened when we tear, cut, or chew cruciferous plants. The activated enzyme creates sulforaphane. Broccoli and cauliflower sprouts are an especially good source of sulforaphane. (7)
Other edible cruciferous plants include:
- Arugula
- Bok choy
- Brussels sprouts
- Cauliflower
- Collard greens
- Horseradish
- Kale
- Mizuna
- Mustard greens
- Wasabi
- Watercress
Even with a healthy diet,
absorption is what really matters. You can eat vitamin D-rich foods and spend a moderate amount of time in the sun, but your body may not absorb vitamin D efficiently.
Cells receive vitamin D through the vitamin D receptor; the VDR gene codes for this receptor. Sick and unhealthy cells may express less of the VDR gene so that they are not able to accept and use vitamin D. Taking an extra vitamin D supplement won't help—absorption is the problem.
Broccoli and cabbage are two cruciferous vegetables that contain a special molecule called sulforaphane. According to research, sulforaphane increases VDR gene expression. Sulforaphane found in cruciferous vegetables and herbs like
wasabi can improve vitamin D absorption to increase bone mass, boost immunity, and fight off inflammation, infection, and cancer.
