The Best Supplements

Better Value. Better Quality.

REX Genetics was founded in the beautiful Bluegrass State,  in beautiful Lexington, Kentucky, The capital Horses of the World; by a team with a passion for providing healthy nutritional supplements grounded in the power of beautiful nature. From the beginning, REX Genetics has created natural supplements that make a difference in the health and well-being of our customers while promoting sustainable practices for planetary health and contributing to the fight against global malnutrition. 


Our supplements are and have always been based in nutritious, whole foods. We carefully combine pure food and botanical extracts with nutrients to support all systems of the body, at potencies appropriate for the specific health objective. Plant enzymes and probiotics are added to enhance digestion and nutrient absorption for increased energy.


We have also taken environmental stewardship seriously from the start.; today, we continue our natural products leadership with innovative formulas that deliver research-proven ingredients, always safety and purity tested in our manufacturer facility in Sunrise, Florida. These products are formulated based on the latest nutritional science to ensure appropriate potencies and optimal combinations for absorption, utility and effectiveness. We’re proud to offer the best-selling prenatal, women’s and men’s supplements and we hear from our customers repeatedly that they never felt a difference from a multivitamin – until they tried ours.


Our products are organic.
