Ambra BioScience is focused on improving our understanding of the complex relationship between nutrition, digestion and health.

We use that knowledge to develop dietary supplements and medical foods that deliver meaningful improvement in human health.

Advancing the Science of Gut Sensory Modulation (GSM)


The gut is the largest endocrine organ in the body. Endocrine organs secrete their hormones directly into the bloodstream in order to affect other organs and biologic systems. The first gut hormones discovered were secretin, gastrin and cholecystokinin but we now recognize a plethora of bioactive peptides and more than 30 gut hormones.

Ambra is focused on the physiologic release of hormones produced by the L-cells in the lower gut. We target the L-cells beyond the stomach where L-cell density is greatest. These cells secrete the hormones GLP-1, PYY and oxyntomodulin in response to food. L-cell hormone secretion is mediated by the sweet, bitter and umami taste receptors that are located on the luminal side of the L-cells. Via the bloodstream, these hormones reach the brain and other organs to affect hunger, satiety, glucose regulation, inflammatory response and mood.

Gut Sensory Modulation (GSM), Ambra’s Platform Technology, leverages the physiologic release of L-cell hormones.

Bringing Gut Sensory Modulation to Market

After six years and more than $20 million in development, Ambra BioScience has created an IP portfolio based on the delivery of sweet, bitter, and umami ingredients (tastants) beyond the stomach in time-released fashion. The tastants are GRAS (Generally Recognized As Safe), non-stimulatory and non-nutritive. Ambra has successfully developed its first commercial GSM-based product called Lovidia. Lovidia is a tableted dietary supplement that activates the L-cell taste receptors in the lower gut. To arrive at the commercial formulation, Ambra tested various tastants on more than 1,000 clinical study participants. A confirmatory, randomized, placebo-controlled clinical study involving 220 test subjects from 23 states verified that the commercial formulation is effective (p=0.02) for hunger control.

A Natural Approach to Better Health

We use ingredients that work naturally with your body’s own digestive and regulatory processes. Mother Earth provides the ingredients, we apply science to turn those ingredients into dietary supplements and medical foods that improve your health.


LOVIDIA® is the first dietary supplement based on the

patented science of Gut Sensory Modulation (GSM)

Based on years of research into the biological mechanisms that drive us to overeat, Lovidia uses a patented mode of action to activate food sensors in your digestive system that control hunger.

Just as the taste buds on your tongue tell you what you’re eating, the food sensors in your digestive system tell you how much you’re eating. Lovidia effectively activates these food sensors ― your body’s own natural hunger-control switch ― to give you the power to avoid overeating.


Control Hunger with Science™

Lovidia is simple, natural and helps you achieve a healthier you.

Lovidia gives you the power to avoid overeating and reach your weight loss goals.  Our proprietary formula works with your body’s own hunger-control processes to reduce hunger so you feel satisfied with fewer calories and lose weight naturally.
