GoodVice

GoodVice is a functional nutrition brand and beverage company headquartered in Sacramento, California, focused on delivering clinically validated gut health solutions through indulgent, flavor-forward drink products. The company was founded by a scientist and former chef who sought to challenge the conventional wellness industry narrative by creating products that combine genuine scientific rigor with sensory pleasure. GoodVice positions itself at the intersection of nutrition science and culinary craft, offering prebiotic fiber-based meal replacement shakes that are formulated to be both effective and genuinely enjoyable to consume.

The core product line consists of powdered shake beverages available in premium flavor profiles including Best-Ever Chocolate, Madagascar Vanilla, and Sweet Cream Coffee. Each serving delivers 10 grams of clinically backed prebiotic oat fiber alongside 15 grams of protein, along with essential vitamins and minerals. The oat fiber used in formulation is described as the world's first of its kind — a proprietary ingredient developed through years of plant fiber research that is simultaneously a potent stimulator of the gut microbiome and exceptionally gentle on digestive systems, reported to be tasteless and free from the gritty texture associated with traditional fiber supplements.

GoodVice differentiates itself through clinical validation. The brand references a registered human clinical study (NCT06739941) reporting that 80% of participants felt better within 14 days with no bloating or gas, 100% of participants tolerated 10 grams daily with zero discomfort, and participants experienced twice the glucose response improvement after two weeks. Pre-clinical SHIME research (Marcobal et al., Nutrients, 2024) further supports a 120% boost in gut metabolites associated with mood and energy.

The brand targets health-conscious consumers who are fatigued by punitive wellness culture and restrictive diet messaging. Its go-to-market philosophy is rooted in what it calls 'radical self-care' — the idea that gut health maintenance should be pleasurable rather than a test of willpower. This positions GoodVice squarely within the growing functional beverage and gut health supplement segments of the CPG market, appealing to consumers seeking premium, science-backed nutrition without sacrificing taste or experience.

The company's Sacramento-based lab serves as the origin point for its fiber ingredient research and product development, suggesting a vertically integrated approach to formulation. GoodVice represents an emerging category of science-led, direct-to-consumer functional nutrition brands that are challenging legacy supplement formats with more consumer-friendly delivery formats.
