Overview

Meta I 3 C provides a well-known compound, Indole-3-Carbinol, at a commonly studied dose. While I3C has a strong mechanistic basis for affecting estrogen metabolism and promising preclinical data, human clinical evidence for its direct efficacy in specific health outcomes, beyond observational studies of cruciferous vegetable intake, is still developing. The inclusion of Rosemary Leaf Extract adds antioxidant properties, but its direct contribution to estrogen metabolism support is less established.

The Good

Provides Indole-3-Carbinol (I3C) which is well-researched for estrogen metabolism support.

I3C is dosed within commonly studied ranges (300 mg daily if taken twice daily).

Manufactured by Metagenics, a reputable brand often associated with practitioner-grade supplements.

The Bad

Human clinical evidence for direct health benefits of I3C supplementation, particularly in the long-term, is moderate and still emerging, with most robust data coming from preclinical and observational studies rather than large-scale RCTs.

The role and optimal dosage of Rosemary Leaf Extract specifically for estrogen metabolism are not well-defined, though it offers general antioxidant benefits.

Potential for mild side effects such as gastrointestinal upset or skin rashes, especially if sensitive.

Is it for you?

Best For: Individuals seeking estrogen hormone balance support, women's health support
