Balchem reports that Optifolin+, its choline-enriched L-5-methyltetrahydrofolate (L-5-MTHF) ingredient, significantly enhanced cellular methylation capacity and DNA methylation in a human cell model. The work appeared in a newly published peer-reviewed study in the Journal of Dietary Supplements.
Balchem presents the results as mechanistic evidence of the ingredient’s biological activity and as added scientific grounding for brands developing next-generation healthy aging and epigenetic health products.
Why the Company Links Methylation to Healthy Aging
According to Balchem, healthy aging is increasingly being viewed through epigenetics, the field concerned with how gene expression is regulated without any change to the genetic code. The company places methylation at the core of that system, describing it as a cellular process that attaches carbon units, also called methyl groups, to molecules such as DNA, influencing DNA’s function and expression.
Balchem adds that genomic instability is associated with disrupted patterns of DNA methylation, and that over time, low availability of methyl donor nutrients, folate among them, can contribute to genomic disruptions.

Two Methyl Donors in a Single Ingredient
Per the company, Optifolin+ was developed to meet this challenge by pairing L-5-MTHF with choline. Both are methyl donors, and Balchem says they operate through interconnected one-carbon metabolic pathways, describing the combination as synergistic.
According to Balchem, the pairing gives Optifolin+ a 7x methyl agent advantage over other folate forms and a methyl capacity of 98%. The company says this optimizes support for the integrity and stability of DNA, which it regards as a foundation of cellular health.
What the 96-Hour Cell Study Measured
According to Balchem, the study was a collaboration with the University of Arkansas for Medical Sciences. Over 96 hours, it assessed the biological activity of Optifolin+ in HepaRG, a human cell model. The company reports that Optifolin+ acted as a modulator of methyl-donor status:
- S-adenosylmethionine (SAM) increased by 71%.
- DNA methylation inside the cell rose by up to 14x.
In Balchem’s view, the results substantiate the role of Optifolin+ in epigenetic regulation, a function the company considers key to keeping DNA stable and the genome intact. It adds that the work shows the ingredient’s choline-enriched structure translating into meaningful activity at the cellular level.

What Formulators Can and Cannot Take From the Data
These are in vitro cell results rather than human clinical data. The publication does not disclose the concentrations tested, a use level, or dosage form guidance, so developers will need to request those details, along with format data such as stability in combined vitamin systems, from the supplier.
According to Balchem, folate is fundamental to how cells function, but methylation efficiency can be affected by modern lifestyle factors stemming from stress or suboptimal diets. For brands that want to move past conventional folate products, the company argues that biological performance needs to be understood.
