1776 Sports Nutrition 'AT-4 Ignite' — same brand credibility failure as the rest of the 1776 line. Product name suggests fat burner / thermogenic / stimulant blend category (the 'ignite' suffix is standard fat-burner marketing shorthand). Thermogenic/fat-burner supplements are the highest-risk supplement category by FDA adverse-event volume, historically associated with recalls of ephedra, DMAA (Jack3d-era), DMHA, higenamine, and other stimulant compounds that produced hospitalizations and fatalities. Without full ingredient disclosure and given the parent brand's demonstrated willingness to sell Schedule Rx pharmaceuticals as supplements, the risk profile is unacceptable. Autofailed under proprietary_blend_hides_dose; safety score reflects the elevated category risk.
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.
