Why this scored 45/100
A women's DIM (diindolylmethane) product explicitly self-described as a 'proprietary blend.' DIM as a single ingredient has a real evidence base for oestrogen metabolism support (shifting the 2-hydroxyestrone / 16-hydroxyestrone ratio toward 2-OH), which is a plausible mechanism for premenstrual symptom and hormone-clearance support. If this were a clearly-dosed DIM product at 100-200 mg, it could score Standard. But calling it a 'proprietary blend' by name — Happy DIM is 'a proprietary blend formulated by Dr Jeff Butterworth' — tells the reviewer that the exact DIM milligram amount and any other actives are not disclosed. Under the Zero-Assumption Rule and the proprietary_blend_hides_dose autofail rule, undisclosed multi-ingredient formulations forfeit tier eligibility. Auto-fail applied.

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.
