Serotonin (5-hydroxytryptophan) is a neurochemical produced in the brain and in the intestines. It plays a large role in helping you keep a positive mood, by regulating sleep, memory, learning, social behavior, and more. Imbalances can lead to depression, anxiety, panic attacks, and other disorders.

SeroFit is a weight management supplement with a unique propietary blend that was patented by Dr. Robert Posner in 2002. It was once exclusively sold and implemented by licensed Serotonin Plus Weight Loss Centers. The supplement is now available to consumers across the U.S. and some international markets. This supplement will reduce sugar and carbohydrate cravings. It is recommended by Dr. Posner if you have recently been diagnosed with “pre-diabetes” or struggling with Type 2 diabetes. It is effective without the unpleasant side effects of prescription medication. Serofit can also help if you are struggling with joint pain, or want Bariatric Surgery but don’t meet the criteria, or are at the risk for heart disease, have issues with your thyroid, or have high blood pressure and/or cholesterol.

The Serotonin Plus Weight Loss Program was developed by Dr. Robert Posner using four pillars: 1) patented Serotonin supplements to help reduce sugar and crabohydrate cravings, 2) dietary meal plan based on real foods 3) weekly visits for behavior modification, and 4) the option to use prescription medication for a medical ‘junp-start’. The average female patient loses 30lbs and the average male loses 40lbs in our 12 week program. We offer free consultations by Zoom. Book your free consultation today to learn more!
