Synergy Insea2®

Synergy InSea2® features berberine, a naturally occurring plant alkaloid used for supporting healthy blood glucose levels, and InSea2®, a clinically studied blend of polyphenols derived from sustainably harvested, wildcrafted brown seaweed shown to support a healthy glycemic response to food.*

  • Supports a Healthy Glycemic Response to Foods*
  • Helps Support Healthy Blood Glucose Levels*

A randomized, double-blind, placebo-controlled trial in dysglycemic patients (N = 65) evaluated InSea2 (combined with 7.5 mcg of chromium picolinate) on glycemic status over a six-month period. At the end of the study period, 18.2% of patients in the test group returned to normal glycemic status compared to no change in glycemic status in the placebo group. In addition, a significant number of subjects changed categorization from impaired fasting glycemia to impaired glucose tolerance, suggesting improvement in insulin sensitivity and glycemic status in the test group.

Overall, subjects in the InSea2 test group had statistically significant improved markers for glycemic health, whereas the placebo subjects—exposed to the same diet and physical activity program—showed a decline in glycemic health markers.*[6] A randomized, double-blind, placebo-controlled, crossover study in healthy subjects (N = 23) aged 19-59 years examined the impact of InSea2 on postload plasma glucose and insulin concentrations. Two capsules with 250 mg of InSea2 were consumed 30 minutes prior to a 50 g load of carbohydrate, and plasma glucose and insulin responses were measured over a three-hour period post-ingestion. Consumption of InSea2 showed a modulation of insulin homeostasis following ingestion of a carbohydrate-rich meal.*[7]

Synergy InSea2® combines clinically studied levels of berberine and InSea2 and is formulated to support a healthy glycemic response to ingested foods while maintaining healthy blood glucose levels.*
