"What began as a passion for working with animals has resulted in an entrepreneurial journey of taking the science from the bay to the lab...and developing a product that people can take to improve health on a cellular level." - Monica Haider, Forbes

"For decades there has been a war on fats such as butter, whole milk, and cheese. But for the first time in 90 years, a San Diego company made an amazing discovery of a new fat, present in butter, and one your body desperately needs." – Steve Atkinson, KGTV ABC10 News

“This discovery [by Seraphina Therapeutics] may elevate C15:0 to the ranks of now hallowed essential fatty acids omega-3 and omega-6 as well as usher in a new dialogue on changing the global guidelines for intake of dietary saturated fatty acids.” – Karen Raterman, New Nutrition Business

“In tests, daily oral supplementation with pure C15:0 for approximately 12 weeks supported healthier cholesterol and glucose homeostasis in obesity models and advanced hepatic form and vitality in liver disease models.”– Vegconomist

“Known as pentadecanoic acid, or C15:0, the dietary saturated fat found in milk, butter, fish, plants and other foods was shown in studies to demonstrate broad health benefits. It would join omega-3 and omega-6 as the only fatty acids considered by nutrition scientists as essential.” – Christopher Doering, FoodDive

"As for the future, Venn-Watson and her team had discovered about 100 molecules naturally present in the serum of both dolphins and humans, that looked like they could protect against the onset of aging-related diseases, so it is very possible we will see more to come from her team. But presently, this discovery of a new [essential] fatty acid is incredibly remarkable." - Micki Wagner, Worth


“I definitely find myself feeling full faster and generally not as hungry. Also, more energy and a little less stressed.”
