"There’s so much we don’t know about how the low-protein diet and medical formula affect us long-term. A tool like the flok app will offer a holistic view so we can correlate what we’re eating with our mood and other symptoms.” 

-Danae Bartke, adult with Classical HCU and Executive Director of HCU Network America   

What is Classical HCU?

Classical Homocystinuria (HCU) is an inherited condition of protein metabolism that affects how the body processes the amino acid methionine. Managing diet, medical formula, medications, and labs are key for long-term health. flok brings the tools and community you need into one supportive hub.
