ButyrEn by Allergy Research Group features the exact same ingredient profile as NutriCology's ButyrAid, providing butyric acid, an important short-chain fatty acid, along with calcium and magnesium. Butyric acid is well-regarded for its role in maintaining a healthy gut lining and supporting the gut microbiome, which can have ripple effects on inflammation, mood, and metabolism. The calcium and magnesium content further enhances bone health, muscle function, and energy levels. While calcium forms are generally absorbable, the reliance on magnesium oxide for a portion of the magnesium content means its systemic absorption might be less efficient compared to other forms. Nevertheless, the product offers a robust combination for targeted gut support and broader mineral benefits, all at a competitive price point, supported by positive user feedback.
