The Choline Factor in One Carbon Metabolism Whitepaper

This whitepaper explores how choline interplays with folate and betaine to support methylation, liver function, and overall metabolic health.
Methylation is a foundational biochemical process that influences everything from gene expression to cellular repair. At the heart of this process lies a critical nutrient—choline—whose role in one-carbon metabolism is often underappreciated.
Authored by Dr. Jonathan Bortz and supported by leading scientific voices like Prof. Dr. Rima Obeid, this study shows that 47% of the subjects with the 677TT genotype had serum folate concentrations in the deficient range (≤ 6.8 nmol/L) and therefore, the demand for betaine as a source for methyl groups to generate methionine from homocysteine is likely higher in individuals with this genotype.1
Whether you’re a nutrition scientist, health professional, or formulator, this deep dive into the methylation cycle reveals why choline deserves a central place in your understanding of cellular nutrition.
