Why this scored 60/100
Forever Fiber is a 30-packet daily-serving fiber supplement blending four fiber sources including FOS (fructooligosaccharides), which functions as a prebiotic. Multi-fiber blends (soluble + insoluble + prebiotic) have supporting evidence for stool regularity, LDL cholesterol reduction, and short-chain fatty-acid production (Slavin 2013 review). This is one of the more evidence-aligned products in Forever Living's MLM lineup because fiber is genuinely under-consumed in Western diets. Held in Standard by the packet delivery format (higher per-gram cost than bulk psyllium), no disclosed per-fiber-source gram amounts, and MLM markup. Would move to Verified with a full gram-per-fiber-type disclosure and third-party FOS purity testing.

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.
