Other Label Statements

General Statements: All Other Content

Cruciferous vegetables (cabbage, broccoli, cauliflower, etc.) are uniquely abundant in a sulfur-containing compound called Indole-3-Carbinol (I3C). In the acidic stomach environment, I3C is readily converted into DIM (diindolylmethane) plus a full spectrum of additional compounds shown to neutralize free radicals and promote proper detoxification.* Studies have shown that I3C supplementation can help maintain the health of the breast and other reproductive organs.*

Brand IP Statement(s) re: (c), (TM), (SM)

Until recently, because of the typical instability of I3C, isolated DIM was the best substitute available, but NOW Indole-3-Carbinol packaging ensures stability and potency during its shelf life.
