About this study

Official title: Effects of a Whole Food Based Nutritional Formulation on Trimethylamine N-oxide and Cardiometabolic Endpoints in Healthy Adults.

Standard Process Heart and Gut Health Study

Read the detailed description

This prospective pilot clinical study will screen 45 healthy participants regularly consuming omnivorous diet (full fat dairy, red meat, eggs, fish) and have elevated serum Trimethyl amine N-oxide (TMAO) levels. Trimethylamine N-oxide (TMAO) is a gut microbiota derived dietary metabolite which is emerging as a significant and independent predictor of cardiovascular disease (CVD) risk mainly through inflammation and oxidative stress pathways. Long term consumption of animal products elevates TMAO levels due to its abundance of TMAO precursors: choline and L-carnitine. As diet plays a key role in altering the microbial composition and subsequent TMAO levels, it is important to investigate if whole food based nutritional formulations can provide the necessary support required to manage TMAO levels and hence, positively impact cardiometabolic endpoints. Towards this end both B and D vitamins have been shown to influence the levels of circulating TMAO while maintaining a healthy gut microenvironment.

This pilot study aims to explore the modulation of TMAO response in healthy adults after supplementation with a whole food matrix-based B vitamins formulation alone, and in combination with vitamin D. The assessments will be compared to the diet only control group.

Secondary outcomes (1)
  1. Secondary

    Another outcome is to explore the beneficial interplay between B and D vitamin supplementation in reducing TMAO levels through modulation of gut microbiome.
