Nutraceuticals are bioactive compounds with potential roles in disease prevention and treatment. Their accessibility and affordability have driven growing interest in obesity care. Among them, bioactive hydrolysates derived from Saccharomyces cerevisiae show promise, yet clinical guidelines seldom address their use. We aimed to develop a guidance statement on their appropriateness using the RAND/UCLA consensus method. A multidisciplinary panel of ten experts rated the appropriateness of a bioactive hydrolysate derived from Saccharomyces cerevisiae across clinical scenarios relevant to obesity care, informed by a targeted evidence review and conducted using the two-round RAND/UCLA consensus method, with ratings on a 1–9 scale. The panel deemed the use of the bioactive hydrolysate derived from Saccharomyces cerevisiae, in combination with lifestyle modifications, as an appropriate intervention for managing obesity-related outcomes. This included its use in patients with specific comorbidities, as an adjunct to standard pharmacotherapy, and in a set of selected clinical scenarios. Based on evidence and expert consensus, a bioactive hydrolysate derived from Saccharomyces cerevisiae is appropriate across a range of clinical scenarios within comprehensive obesity care. Further studies should evaluate long-term effectiveness, broader populations and combination regimens.
