The Promise

Product identity and composition Indole‑3‑carbinol–based cruciferous blend

Ultra I‑3‑C supplies a concentrated dose of indole‑3‑carbinol together with standardized cruciferous vegetable extracts in a vegetarian capsule.

Primary ingredient

Indole‑3‑carbinol (I‑3‑C) 200 mg per capsule.

Proprietary cruciferous blend

Proprietary blend 100 mg containing standardized broccoli extract (sprouts), whole‑plant cauliflower, and whole‑plant Brussels sprout.

Formulation & delivery

Vegetarian hydroxypropyl methylcellulose (HPMC) capsule; other ingredients: cellulose, vegetable stearate.

Dietary & quality facts

Free of yeast, wheat, gluten, soy, milk/dairy, corn, sodium, sugar, starch, artificial preservatives/flavoring, and GMOs.

Why It Works

Mechanisms and supported roles Evidence‑stated metabolic actions and cellular support*

I‑3‑C and cruciferous phytochemicals act through known metabolic pathways and identifiable metabolites.

01

Conversion to active metabolite

I‑3‑C is converted in the stomach to diindolylmethane (DIM), an active metabolite with related activity.

02

Phase II enzyme induction

I‑3‑C induces phase II enzymes, including glutathione S‑transferase (GST), involved in detoxification.

03

Estrogen metabolism modulation

I‑3‑C promotes a healthier ratio of weak to strong estrogens, favoring the weaker estrogens.*

04

Antioxidant and cellular support*

Contains cruciferous‑derived phytochemicals that function as antioxidants and support healthy breast, cervical, and prostate cell metabolism (as stated).*

Product education

Ultra I-3-C by Douglas Laboratories

Ultra I-3-C — provided by Douglas Laboratories, supplies significant amounts of indole-3-carbinol (I-3-C) in a proprietary blend of cruciferous vegetables for healthy hormone balance and cellular health. Indole-3-carbinol is a member of the class of sulfur-containing chemicals called glucosinolates, phytochemicals found in high amounts in cruciferous vegetables such as broccoli, cauliflower, and Brussels sprouts. It functions as an antioxidant, stimulates natural detoxification enzymes, and supports normal hormone metabolism. Furthermore, I-3-C supports the function of healthy breast and cervical cells and has shown a promising ability to support prostate cell metabolism.*

In the stomach, indole 3-carbinol must be broken down into its active metabolite diindolylmethane, which also has similar health benefits. I-3-C supports healthy estrogen metabolism by promoting a healthy ratio of weak estrogens to strong estrogens in favor of the weak, less potent estrogens. It also induces phase II enzymes including glutathione S-transferase (GST). Cruciferous vegetables like broccoli and cauliflower offer protective sulforophane compounds known for their ability to induce protective detoxifying enzymes.*

INDICATIONS Ultra I-3-C may be a useful dietary supplement for individuals wishing to supplement their diet with indole-3-carbinol to support healthy estrogen metabolism.*

Key Benefits

  • Supports healthy hormone balance*
  • Promotes normal estrogen metabolism*
  • Contains antioxidant properties

How It Works / Key Ingredients

Indole-3-carbinol is derived from cruciferous vegetables and aids in detoxification and hormone regulation.

How to Use

As a dietary supplement, adults take 1 capsule daily or as directed by your healthcare professional.
