Description

This is an open-label, two-arm pilot study designed to evaluate the tolerability, consumer acceptability, and well-being outcomes of a multi-ingredient protein formula, available in two flavors (Vanilla Protein Formula and Chocolate Protein Formula), in generally healthy adults aged 21-65 with a BMI of 18.5-34.9 kg/m². Approximately 50 participants will be allocated in a 1:1 ratio, balanced on age and gender, to receive either the vanilla or chocolate formula (approximately 25 participants per arm). Participants will consume one serving (1 scoop, 51 grams) of their assigned product daily for 15 consecutive days, reconstituted in water or a beverage of their choice. The primary outcomes are safety and tolerability, assessed via a Safety and Tolerability Questionnaire, and changes in global health assessed using the Global-10 scale. Secondary outcomes include changes in cognitive function assessed using the PROMIS v2.0 Cognitive Function - Abilities 8a instruments, and consumer acceptability, measured using a 9-point hedonic liking scale. All assessments are self-reported and completed electronically at home.

Interventions

Vanilla Protein Formula (Dietary supplement)
A vanilla-flavored, multi-ingredient ready-to-mix powdered dietary supplement combining YESTEIN fermented yeast protein, grass-fed bovine collagen peptides, OptiCreatine creatine monohydrate, and FiberEssence prebiotic fiber blend, sweetened with allulose, Reb M, and coconut sugar. Each 51-gram serving (1 scoop) provides 24 g protein, 2 g sugar, 3.5 g fat, and 5 g fiber. Consumed once daily for 15 days.
Chocolate Protein Formula (Dietary supplement)
A chocolate-flavored, multi-ingredient ready-to-mix powdered dietary supplement combining YESTEIN fermented yeast protein, grass-fed bovine collagen peptides, OptiCreatine creatine monohydrate, and FiberEssence organic prebiotic fiber blend, flavored with cocoa powder and organic natural cocoa extract, sweetened with allulose, Reb M, and coconut sugar, and containing MCT oil powder. Each 51-gram serving (1 scoop) provides 25 g protein, 2 g sugar, 3.5 g fat, and 5 g fiber. Consumed once daily for 15 days.
