The Sundrops Protocol

In many ways, the body is a system of opposing functions that communicate with each other to maintain balance. Beginning in 2004 Mark Herrin identified and confirmed that many of the genes and molecules required to maintain this balance were activated and impacted through the two primary energy-forming pathways. One using fat and the other glucose (carbohydrate). A relatively small number of lifestyle and dietary choices are key to controlling these pathways that are needed to maintain balance and support health.

Starting at approximately age 25, the body begins reducing the production of hormones. As a consequence, inflammation typically starts a gradual increase while protective antioxidants begin declining. These changes uniquely impact the two powerful energy-forming pathways. Other factors influencing these changes are genetic weakness or life events like stress, insomnia, infection or injury. The result of all these changes is disruption of the normal biochemical pathway balance in the body.

The Sundrops Protocol provides a framework
to develop individualized plans
designed to maintain the balance and support normal
function through specifically targeted nutrition,
supplementation, and exercise.

Sundrops nutritionists and dietitians are as passionate about the research as they are about making sure clients continue to do better. In-depth consultations are available by appointment. Call, visit, or email us at [email protected] to schedule. $150 per hour or 15 minutes fractions thereof.
