About our founder: Sari Eitches, MD

Dr. Sari Eitches is a dual board-certified holistic internist who has treated thousands of patients in New York City and Los Angeles for over 13 years. Dr. Sari is sought out by a high profile clientele, and frequently featured in the media for her expertise in supplements and women’s health. She is a highly-regarded consultant as a thought leader in evidence-based holistic medicine.

In her integrative concierge practice at Cedars-Sinai, she came across hundreds of women whose physical and emotional symptoms varied with phases of their menstrual cycles. While conventional doctors may offer prescription medication options, Dr. Sari saw a growing demand for natural alternatives or supplements to complement traditional medicine.

Dr. Sari began to notice rhythmic patterns, such as fatigue, pain and overall loss of quality of life among these women and was struck by how universal their experiences were. She began to think about a woman’s needs throughout her entire monthly cycle, as opposed to just her 5-7 day period.

Dr Sari pored over hundreds of clinical studies to develop a unique combination of supplement cycling to treat these varied rhythmic symptoms. She then first introduced a beta version of Lunar Sync to her practice in 2018. The results were so positive and dramatic she was moved to make these supplements accessible to a all. In 2021, her current formulation was patented and proven effective in a clinical study.
