Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
VeggieVerve/Livingston Naturals 'Organic Soursop Turmeric Bitters' combines soursop (multiple parts of the plant), turmeric, nettle, Cape aloe, ginger, clove, black pepper, and apple cider vinegar as a digestive bitters formulation. Bitters as a category have modest traditional-use evidence for stimulating digestive secretions, but the specific product carries a foreground safety concern: soursop (Annona muricata) contains annonacin, an inhibitor of mitochondrial complex I associated with atypical parkinsonism in Guadeloupe epidemiological studies (Caparros-Lefebvre 1999, 2002). Featuring 'multiple parts of the soursop plant' as the leading ingredient in a formula intended for regular daily use is exactly the chronic-exposure pattern the neurological safety data warns against. Cape aloe is a stimulant laxative associated with dependence and electrolyte disturbance at chronic doses. Multi-herb anticoagulant potentiation (turmeric + ginger + clove) creates bleeding-risk concerns for users on prescription blood thinners. Autofail on safety_concern.
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.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
