Zahler is a 3rd-generation family company proudly continuing the work of legendary founder Rachel Zahler, PhD. Growing from her inspiring, one-on-one consultation service, the Zahler family felt the need for better, more innovative, smarter nutritional solutions. When we elected to dive into the scientific research of raw ingredients and advanced formulations, it took painstaking, meticulous research and a solid understanding of the human body. More scientists, doctors and nutritionists were recruited, and the very first effective Zahler formula was created. Zahler supplements are Kosher, pure, natural and rooted in nature’s organic bounty.
