(12 cans). is a product from SINGERS HEALTH PRODUCTS, categorized under Energy & metabolic support in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

48/100 overall — Rejected tier (0–49 band). Per-dimension breakdown: Manufacturing 55, Evidence 50, Safety 50, Formulation 45, Transparency 45, Sustainability 42. Scored as of 2026-08-24.

Forever FAB is a canned energy drink (8.4 fl oz, 12-can case) from Forever Living's MLM lineup, built on B vitamins + guarana (a caffeine source) plus adaptogen-style branding. This is a functional beverage rather than a targeted nutraceutical: caffeine from guarana delivers the acute 'fast energy' effect while B vitamins contribute little to acute energy in a non-deficient person (Kennedy 2016 review). Held in Rejected by ambiguous per-serving caffeine disclosure typical of energy-drink formats, added sugars/sweeteners, MLM markup, and the fact that a 12-can case pricing is well above a comparable Celsius or Zevia. Would move to Standard with clear caffeine mg per can, unsweetened base, and no MLM markup.

Strongest: Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status) and Evidence at 50/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Transparency at 45/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 42/100 (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 Standard with clear caffeine mg per can, unsweetened base, and no MLM markup.
