How it Works


Take 1-3 chewable SUGARDOWN® tablets before foods or liquids that contain carbohydrates.


Insets-2Enjoy your carbohydrate meal, snack or drink with confidence!


SUGARDOWN® works in the gastrointestinal tract,
blocking the enzymes that degrade carbohydrates in food, thus reducing the available glucose for absorption into the bloodstream.


Feel the difference!

If you use a glucose monitor to check your glucose levels after meals, do so with and without SUGARDOWN® to see the difference.

We are so confident that SUGARDOWN® will work for you we provide you a money-back guarantee.

How it Works

SUGARDOWN® is a chewable tablet that inhibits the enzyme activity that breaks down complex carbohydrates into glucose, reducing the amount of glucose that is available for absorption, thus moderating the after-meal glucose (blood sugar) spike. Many foods and drinks contain carbohydrates that break down rapidly during the digestion process, creating an unnaturally rapid increase in blood sugar. A rapid, sustained, and abnormally high rise in blood sugar can hurt the body over time and can lead to disease such as diabetes and heart disease.


SUGARDOWN® works in the gastrointestinal tract. Our competitors’ supplements claim to work systemically to support good pancreatic, brain, liver, blood, cell, insulin activity. SUGARDOWN® works proactively to reduce the glycemic impact of carbohydrate foods before they are absorbed as glucose.

Clinically Proven to Work

Managing blood sugar levels is one key to maintaining optimum health and weight, especially for those at risk of diabetes or pre-diabetes. Mannans, a group of complex carbohydrates from plants, possess significant biological activity in moderating blood glucose levels after a meal.

Safety is Our Priority

SUGARDOWN® is made in the USA and manufactured with the highest level of integrity and oversight using Good Manufacturing Procedure (GMP) at a Food and Drug Administration-inspected facility.

SUGARDOWN® is a single molecular structure with no side-effects and no known drug interaction.

FDA Submission for Structure and Function claims
SUGARDOWN® has submitted structure and function claims to the FDA in 2010. All SUGARDOWN® ingredients are considered Generally Regarded as Safe (GRAS).

Scientists at Boston Therapeutics have optimized the chemistry of a specific plant-derived mannan to develop SUGARDOWN®, our first of several products to address the growing need for blood glucose management.

A Chewable Dietary Supplement

SUGARDOWN® is now available as a natural, convenient and chewable dietary supplement that is taken before carbohydrate-containing meals to reduce the absorption of glucose from the intestinal tract. The proprietary mannan formulation in SUGARDOWN® works in several beneficial ways. SUGARDOWN® binds to carbohydrates and digestive enzymes preventing the breakdown of complex carbohydrates in foods to glucose. It temporarily coats the digestive tract to slow the absorption of glucose. In addition, SUGARDOWN® induces a feeling of fullness and can therefore support portion control. All of these non-systemic mechanisms combined lead to lowering the rate of glucose absorption from the intestinal tract into the blood.

Our expertise in complex carbohydrate chemistry has resulted in a dietary supplement that is a pure and optimized formulation, and is manufactured in the U.S. at a GMP-certified facility. All the ingredients in SUGARDOWN® are GRAS-certified (Generally Regarded As Safe) and registered with the United States Food and Drug Administration (FDA), and structure and function claims for SUGARDOWN® have been submitted to the FDA. Those concerned about carbohydrate intake and high blood sugar may find SUGARDOWN® an effective dietary supplement.

Single Claim

SUGARDOWN® was created to help our customers support healthy post-meal blood sugar levels. We do not make any medical claim to diagnose, treat, cure or prevent any disease.
