About Us


With more than eighty years of combined reproductive medicine experience, the physicians of Prolog Health have helped scores of thousands of couples conceive their dreams of having a family. Each of us is concerned with our patient’s optimal health and wellness and we teach a lifestyle of nutrition, exercise, fitness, and psychosocial well-being. 

In addition to our leading Reproductive Endocrinologists and Infertility specialists, our team includes world-class academic physician consultants, embryologists, and nutritionists. The goal was to provide superlative, evidence-based nutritional supplements that we would prescribe for our own patients.

In 2016 we began developing superior, whole foods-based multivitamins and nutritional supplements for reproductive health. In large part, this was due to the fact that most of the supplements available in North America are partially or completely from Asian countries and have questionable quality and purity. Except for several ingredients not available in this country, all our vitamins and supplements are from the United States and always ethically sourced, meticulously created, and never tested on animals. Our products are all manufactured in the United States, are free from contaminants, and are tested for purity by an outside reference laboratory. 

To provide you with the best possible products and seamless customer experience, we have partnered with two well-established nutritional supplements companies: our manufacturer (founded in 1990) and our fulfillment and distribution center (founded 1992).


We are committed to helping build healthy families by creating pure, safe, and effective vitamins and supplements.
