Victoza & Vitamin B2
Suppresses absorption of Vitamin B2. This medication is commonly used for Weight Loss
Why Victoza affects Vitamin B2
Riboflavin is important for cellular energy production and serves as a cofactor in pathways that activate and utilize other B vitamins. While reduced food intake during GLP-1 therapy creates a broader rationale for maintaining B-vitamin coverage, current studies do not identify riboflavin as a common GLP-1-related deficiency. In fact, available dietary studies generally show adequate riboflavin intake among GLP-1 users. Its inclusion is therefore best positioned as foundational support for energy and nutrient metabolism during reduced-calorie intake, rather than correction of a demonstrated GLP-1 nutrient deficiency.
