[Rescored via evidence crawl] Previous score 71 → new 76. Evidence found: Brien S, Lewith G, Walker A, Hicks SM, Middleton D. Bromelain as a Treatment for Osteoarthritis: A Review of Clinical Studies. Evid Based Complement Alternat Med. 2004;1(3):251-257. | Walker AF et al. Bromelain reduces mild acute knee pain and improves well-being in a dose-dependent fashion in an open study of otherwise healthy adults. Phytomedicine. 2002;9(8):681-686.. Rationale: Enteric coating (referenced in product name 'Specially Coated') is meaningful for bromelain: it protects the proteolytic enzyme from gastric acid destruction, allowing systemic absorption for anti-inflammatory effects vs local digestive-only action. 500 mg dose aligns with Walker 2002 dose-response study. Uplift to 76 for delivery-technology plus therapeutic-dose alignment.
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.

Life Extension Specially Coated Bromelain 500g/60ct is a product from Life Extension, categorized under Joint, bone & connective tissue health in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
71/100 overall — Verified tier (70–84 band). Per-dimension breakdown: Manufacturing 76, Formulation 75, Transparency 72, Evidence 70, Safety 68, Sustainability 58. Scored as of 2026-08-24.
Life Extension is a long-established Verified-tier brand with per-lot COA publication and a genuine science-editorial arm. Their Specially Coated Bromelain uses an enteric coating to protect the pineapple-derived proteolytic enzyme from stomach acid, which meaningfully increases the fraction reaching the small intestine intact — critical because bromelain's absorbed effect (systemic anti-inflammatory / fibrinolytic) requires intact enzyme delivery. Evidence for bromelain in post-surgical swelling, mild osteoarthritis pain, and sinusitis is fair (Brien 2004 systematic review — mixed but positive signal at 500–2000 mg/day GDU-standardized). Held below Elite because the title's "500g" is likely a listing typo for 500 mg and per-capsule GDU potency should be more prominent. Would move to Elite with clearer GDU/FIP potency disclosure and per-lot analytical certificate linked from the label.
Strongest: Manufacturing at 76/100 (third-party testing, GMP compliance, and facility audit status) and Formulation at 75/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Safety at 68/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 58/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
Would move to Elite with clearer GDU/FIP potency disclosure and per-lot analytical certificate linked from the label.

The Vyvata Scoring Framework rates every listed product 0–100 across six dimensions: Evidence, Formulation, Manufacturing, Safety, Transparency, and Sustainability. Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
