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 →
Jevity 1.2 With Fiber is Abbott Nutrition's prescription-tier enteral (tube-feeding) formula — 1.2 kcal/mL polymeric feed with added FOS and soy polysaccharide fiber, designed for hospital and long-term-care patients unable to meet nutrition needs orally. It is not a consumer biohacking supplement and does not belong in a Vyvata protocol. Scored out of scope. The Abbott manufacturing pedigree is genuinely high; the categorization mismatch is what disqualifies it. Consumers looking for a real oral meal-replacement should consider Huel, Kate Farms Standard, or similar full-food formulas — not clinical enteral feeds.
Auto-fail rule triggered: Out of scope for biohacking.
The product is not appropriate for the biohacking / human-wellness catalog scope. Examples: veterinary products, industrial chemicals, prescription drugs not intended for self-supplementation. See the full rubric →
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.

Strongest: Manufacturing at 78/100 (third-party testing, GMP compliance, and facility audit status) and Evidence at 72/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Safety at 55/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 45/100 (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.
This product triggered the Vyvata auto-fail rule "out_of_scope_for_biohacking", which places it in the Rejected tier regardless of its scores on other dimensions. See the full explanation above and the methodology page for the current list of auto-fail rules.

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.
