Their Food Tech Startup Focuses on Bone Health
Adrienne Bitar and Jenny Han are the co-founders of Seen Nutrition, an all-natural calcium chew for women.
Adrienne Bitar, a food studies lecturer at Cornell University, and Dr. Jenny Han, a clinical pharmacist, believe that women’s poor bone health has been accepted as an inherent part of aging for too long. Dr. Han herself was diagnosed with osteoporosis at age 29, while Bitar’s mother has suffered from osteoporosis and fractures since she was in her 40s. The Ithaca, New York-based duo spent 18 months researching and developing what they say is the first dietary calcium chew on the U.S. market made entirely from real foods. In November 2023, Bitar and Han took their product to market and launched Seen Nutrition, a women’s health company focused on the unique nutritional needs of women in midlife. Today, the co-founders are looking to expand their manufacturing capabilities so they can continue to bring Seen Nutrition to women across the country.
Editor’s Note: Seen Nutrition has been named to The Story Exchange’s 2025 list of 10 Brilliant Business Ideas. Here’s our lightly edited Q&A, with Bitar.
