什么是GTF（耐糖因子）？

GTF（耐糖因子）全名是Glucose Tolerance Factor，存在于人体组织细胞内，主要功能在维持糖类的正常代谢，并与胰岛素结合，将血液中的葡萄糖送入各细胞内，因而称之为“耐糖因子”。

GTF是三价铬、维生素与氨基酸所组成的复合体，正常人由食物中摄取到的三价铬，可在体内转化成为GTF，进而协助葡萄糖的正常代谢。然而劳动、怀孕、肥胖、年老、酗酒、手术或疾病等各种状况，将导致体内GTF的大量消耗，使其由尿液中排出，因而造成GTF的缺乏。

如果三价铬长期摄取不足，体内合成的GTF将会因此而减少，所以吸收到的葡萄糖液不能有效地进入细胞内，高浓度的血糖流经肾脏时则无法完全地被吸收，多余的葡萄糖即出现在尿液中，而造成糖尿病的临床症状。

1957年发现GTF时，对其功效并非相当确认，直到1999年才由美国阿拉巴马大学教授约翰文森（John B.Vincent）博士揭开它的面纱。原来GTF是胰岛素的辅酵素，当我们从食物中获取养分时，经小肠吸收到血液，接着胰岛素就会通知组织细胞去取得葡萄糖，存在于细胞内的GTF去接收胰岛素所传达的讯息，一旦细胞内部缺乏了GTF这种必要的辅酵素时，葡萄糖的代谢将会变得不正常，血糖也会因此而升高，人们就会生病，且逐渐失去健康。

根据2003年4月于波士顿举行的“健康与疾病研讨会”当中，多位学者所提出的研究成果发现，GTF对于糖尿病、心血管疾病与非典型忧郁症等皆具有改善的功能。再者也有学者发现，GTF会直接影响基因表现，人体中一旦缺乏了GTF，老化的速度也会急速加快。根据英国医学博士史蒂文大卫（Stephen Davies）博士研究发现，人到中年以后，GTF在体内的含量会不断下降，至七十岁时GTF含量几乎降至儿童时期的一半左右，所以随着年龄的增加，人体将会产生许多的健康问题，如老化、糖尿病、心血管疾病、容易受到感染、身材变形、体能衰退等，所以人到中年以后看病的次数会逐年增加，常常会令人深感时不与我。

What is Glucose Tolerance Factor (GTF)?

Glucose Tolerence Factor (GTF) is found in our body tissues and cells. Its main function is to maintain normal glucose metabolism. It combines with insulin to transport blood glucose into our body cells.

GTF is a compound consists of trivalent chromium, vitamin and amino acid. Healthy people obtain trivalent chromium through diet, and chromium is then being converted to GTF to assist in glucose metabolism. However, streneous physical work, pregnancy, obesity, aging, alcoholism, surgery and diseases can cause excessive loss of GTF in the body through secretion of urine and hence causing GTF deficiency.

If the intake of trivalent chromium is insufficient, GTF synthesis in our body will be reduced, and glucose will not be transported into the cells efficiently. High concentration of blood glucose cannot be reabsorbed by the kidney. This results in the presence of excess glucose in urine and clinical symptoms of diabetes.

When GTF was discovered in 1957, its functions were not conclusive. Functions of GTF were later identified by Dr. John B.Vincent from Alabama University, USA in 1999. GTF is in fact a coenzyme of insulin. The nutrients we obtained from food is obsorbed into the blood through small intestines. Insulin plays a part to notify our tissues and cells to absorb glucose; while GTF in the cells will receive the signals from insulin. Once there is a lack of this essential GTF coenzyme in the cells, glucose metabolism will become abnormal and blood glucose level will increase. We will then fall sick and our health will deteriorate gradually.

In a "Health and Disease Seminar" held at Boston in April 2003, results of researches carried out by a number of scholars reveales that GTF can improve condition of patients with diabetes, cardiovascular diseases and atypical depression. there is also research showing that GTF affects gene expressions indirectly. If a person is lack of GTF, the aging process increase rapidly. According to a research done by England Medicine Professor, Dr Stephen Davies, the level of GTF in our body reduces with age. At the age of 70, the level of GTF in our body is halved of that during childhood. Therefore, with the increase in age, we face more and more health problems, such as aging, diabetes, cardiovascular disease, more susceptible to infections, change in body shape, decline in the physical strength etc.

The Discovery of GTF

GTF(Glucose Tolerance Factor) was discovered by a former director of USDA, USA, Dr. Welter Mertz in 1957. GTF is a stable inside human's body. It is distributed widely in all bady's calls. It can regulate the metabolism of the glucose, lipid and protein levels in the body. GTF is built up from 3 elements namely trivalent chromium, vitamins and amino acids. Throught years of research and development, Professor Dr. Frank Mao, a dairy specialist as well as an endocrinologist had finally came out with a biotechnological product that contains stable form of GTF trivalent chromium. GTF is not only easily being absorbed by the body cells to form GTF, it also increases the absorption and utilization rate of other nutrients in the body. GTF increases cells metabolism which is essential in maintaining the body's health and beauty.
