Kristin Hirano

Kristin Hirano, MS, RD, CN, CD, is a registered dietitian, her background includes a Bachelor of Science in Food Science & Human Nutrition and a Master of Science in Human Nutrition. Kristin is certified in Adult Weight Management, and she is passionate about helping individuals, especially those who consider themselves weight-loss resistant, achieve lasting metabolic change. Her work sits at the intersection of clinical nutrition, gut microbiome science, and product innovation, bridging research and real-world biohacking applications. Her guiding belief, “All Health Begins in the Gut,” highlights the gut as the starting point for strength, resilience, and optimal health. That vision led her to create JUST BETTER BRANDS, a Seattle-based functional nutrition company dedicated to building evidence-based products that optimize metabolic health. Kristin believes nutrition is one of the strongest and most modifiable environmental factors that can be used to promote optimal health and reduce overall risk of disease during an individual’s lifetime. She saw in her work how small, daily choices could influence long-term health, and she recognized the urgent need for practical solutions that fit into real life. Kristin identified fiber deficiency as a foundational driver of metabolic dysfunction and developed a clinically proven prebiotic soluble fiber to selectively nourish beneficial gut bacteria, and support glycemic control and weight management. She is now expanding that work with the launch of just better.® allulose, a rare zero-calorie natural sugar that delivers the taste of sugar but is metabolized differently by the body and has little to no effect on blood glucose or insulin levels. A sought-after speaker at health, nutrition, and innovation conferences, Kristin is known for translating complex gut microbiome and metabolic science into practical, actionable strategies for optimal health.
