Choline Improves Postmenopause Brain Function: Balchem Study
- New clinical research published in the peer-reviewed journal Nutrients indicates that choline supplementation can influence brain network efficiency and working memory-related brain activation in postmenopausal women.
- The research was a pilot, randomized, cross-over study involving 20 healthy postmenopausal women between the ages of 50 and 65.
- Researchers observed that the administration of choline had a rapid effect on the brain.
New clinical research published in the peer-reviewed journal Nutrients indicates that choline supplementation can influence brain network efficiency and working memory-related brain activation in postmenopausal women. The study, which utilized functional magnetic resonance imaging (fMRI), suggests that choline intake may optimize brain efficiency in a population that has been historically underrepresented in nutrition science.
The research was a pilot, randomized, cross-over study involving 20 healthy postmenopausal women between the ages of 50 and 65. Participants were administered either a placebo or 1650 mg of choline, specifically using the VitaCholine ingredient supplied by Balchem, before performing a working memory exercise known as an N-back test while undergoing fMRI scans.
Findings on Brain Connectivity and Efficiency
Researchers observed that the administration of choline had a rapid effect on the brain. Specifically, the study found that choline intake significantly increased functional connectivity within the working memory network just 3 hours after consumption compared to the placebo group.
This increase in connectivity is linked to optimized brain efficiency during cognitive tasks. The study focused on how oral choline affects working memory-related brain activation and the overall functional connectivity of the brain in women who have passed through menopause.
The Biological Role of Choline and Estrogen
The scientific context for this research involves the relationship between hormonal changes and nutrient production. According to Professor Julie A. Dumas of the University of Vermont, the lead author of the study, estrogen serves as a key driver for the production of choline within the body.
Estrogen is a key driver of choline production in the body, so when levels of the hormone drop during menopause, women are at increased risk of choline deficiency. This is important because choline is needed to make acetylcholine, a neurotransmitter involved in cognitive functions such as mood, memory and attention

Because acetylcholine is critical for maintaining attention, memory, and mood, a deficiency resulting from the drop in estrogen during menopause may impact cognitive performance. The research aims to demonstrate how supplementing with choline can address this gap.
Study Methodology and Implementation
The study was conducted by a multidisciplinary team including researchers from the University of Vermont’s Department of Psychiatry and Department of Radiology, as well as the Colorado Center for Reproductive Medicine. The mechanistic nature of the study allowed researchers to map the specific effects of choline on the brain’s working memory networks using fMRI technology.
The use of the N-back test during the fMRI scans provided a standardized method to measure how the brain activates and connects when managing working memory tasks. By comparing the 1650 mg dose of VitaCholine against a placebo, the team could isolate the impact of the supplement on brain network efficiency.
Implications for Personalized Nutrition
The findings suggest that choline supplementation may offer a targeted nutritional solution for supporting women’s cognitive health during the postmenopausal stage of life. This research is noted as an important step toward the development of more personalized nutritional strategies that account for the specific physiological changes women experience during menopause.
Further research continues into this area, including dose-ranging studies to better understand the relationship between the functioning of the cholinergic system and the hormone changes that occur after menopause.
