Key Benefits:
- 300 mg of diindolylmethane in each vegetarian capsule
- Features DIM, which is a naturally-occurring phytonutrient from cruciferous vegetables
- Supports efficient hormone metabolism*
- Promotes enhanced stamina and physical endurance*

Benefits of DIM
This nutrient found naturally within kale, broccoli, cauliflower and other cruciferous vegetables supports healthy estrogen balance in men and women.* Studies show that DIM may contribute to healthy metabolism of estrogen metabolites.*
Healthy Hormone Balance
An imbalance of hormones can lead to a loss of energy and low mood. Supporting this area of your health may contribute to enhanced endurance, stamina and energy, not to mention a positive mood.* Nature’s Lab DIM includes BioPerine®. This proprietary formula of black pepper extract increases the bioavailability of DIM which means better absorption within your digestive system.*

Six-dimension breakdown
Why this scored 54/100
300mg DIM plus BioPerine to boost absorption — DIM's evidence for shifting estrogen metabolite ratios is real but the clinical significance is modest (Thomson 2017 pilot). BioPerine addition is the right formulation move given DIM's poor oral bioavailability. Structure/function claims are appropriate, no drug-level claims.
Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
