NGC® – Natural Glycemic Control
Reztart was developed by a group of Swedish doctors with the aim of solving a common everyday problem – getting the right nutrition and counteracting fatigue and ill health, which are often due to unbalanced eating habits.
All Reztart products contain the proprietary nutrient mix NGC®, a composition of natural nutrients from, among other things, dried apples, rose hips, sugar beet fiber, peas, omega-3 and omega-6 enriched eggs, and whey protein.

The effect of NGC® is scientifically proven
NGC has been tested in several smaller studies and, in summary, there is a clear indication that NGC, with its composition of nutrients, has a low glycemic index, i.e. does not cause high blood sugar levels after ingestion or contribute to “post-meal fatigue.”
Exposing the body to high blood sugar levels is associated with health risks. NGC can help reduce such risks. The study results also indicate that not only can a reduction in blood sugar levels be achieved with regular use of NGC, but also a reduction in blood lipids, inflammation parameters and body weight.
We have conducted clinical studies, tests and product development in collaboration with international researchers and experts for longer than since 2000. We have conducted over 20 tests and studies, including 3 clinical studies that have been published internationally.
Study on gestational diabetes
Gestational Diabetes Mellitus (GDM) means that diabetes occurs in connection with pregnancy and entails health risks for both woman and child. Not least because the fetus/child often becomes very large.
A study conducted with NGC on women with gestational diabetes was carried out in such a way that NGC was ingested half an hour before an ordinary meal (breakfast, lunch and dinner). In the control group, a standardized milk powder was given in a corresponding manner before each meal. However, all participants received standard dietary advice for gestational diabetics.
The study result showed that the NGC group had lower blood sugar levels after meals and showed a tendency towards lower birth weight for the children.

Study on type 2 diabetes
Type 2 diabetes is characterized by insulin insensitivity, i.e. deficiencies in the body’s ability to normalize blood sugar. Elevated blood sugar levels are associated with well-known health risks (mainly cardiovascular disease and obesity) and type 2 diabetics usually receive dietary advice to reduce these risks, often supplemented with drug treatment.
A study conducted with NGC on men and women with type 2 diabetes was carried out in such a way that NGC was ingested half an hour before an ordinary meal (breakfast, lunch and dinner). In the control group, a standardized milk powder was given in a corresponding manner before each meal. However, all participants received standard dietary advice.
The study result showed that the NGC group had lower blood glucose levels after meals, lower markers for inflammation and reduced blood lipids.
