Natural Herpes Immune Support Formula – by Livingston Naturals

Six-dimension breakdown

Why this scored 28/100

VeggieVerve/Livingston Naturals 'Natural Herpes Immune Support Formula' is one of the most severe autofail cases in this batch. First, herpes (HSV-1, HSV-2, VZV/shingles) is a diagnosed viral infection — naming a supplement after a specific disease and marketing it for 'cold sores, shingles, viral immunity' is textbook unverified_disease_claim, an FDA warning-letter category that supplement brands are repeatedly cited for. Second, the disclosed dose is dangerous: '35,000 mg vitamin C' translates to 35 grams — more than 500x the RDA of 65-90 mg and roughly 20x the tolerable upper limit of 2000 mg/day. At 35 g/day, vitamin C causes severe osmotic diarrhea, kidney stones in oxalate-prone individuals, iron overload in hemochromatosis, and possible interference with chemotherapy. This is not a formulation choice, it is a safety_concern. Third, self-treating herpes with an OTC supplement delays evidence-based antiviral treatment (acyclovir, valacyclovir, famciclovir) that meaningfully reduces outbreak duration and transmission risk. Compound autofails: unverified_disease_claim + safety_concern (megadose vitamin C).

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.
