absorption and tolerability studies of an emulsion containing the coconut oil-derived glycerol tridecanoate in healthy men

Conditions: Polycystic Ovary Syndrome

Summary: the primary aim of the study is to test safety and tolerance of oral intake of gt oil in the form of a non-diary based emulsion (10g of gt per emulsion) in healthy men. this will be a single center study, and the recruitment is expected to happen over a 1-2- month's period.

polycystic ovarian syndrome (pcos) is a hormonal disorder contributing to infertility in women. pcos is also associated with insulin resistance (ir) occurring at a high incidence rate of 50-70%. ir is a condition in which your body loses sensitivity to insulin requiring higher levels of it to maintain normal glucose levels in blood which hormones production from ovaries. studies have demonstrated that the prevalence of the metabolic syndrome which is a cluster of condition such as increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol in women with pcos is significantly higher than that of the general population. medications that improve insulin sensitivity, such as thiazolidinediones (tzds) and metformin, an insulin sensitizer have been used in treating women with pcos. metformin major side effects consist of nausea, vomiting and gastrointestinal distress. tzds are withdrawn from the market due to their adverse effect profile, which includes liver toxicity, weight gain, swelling due to water retention and cardiovascular diseases. as current treatment options are inadequate, there is a clinical need to identify new treatment regimens with a reduced adverse effect profile to improve the management of pcos and its related metabolic syndrome. glyceryl tridecanoate (gt) is a medium chain triglyceride (mct); a form of dietary fat, which has a long history of safe use in in foods, drugs, cosmetics, can even be provided via the veins in individuals requiring supplemental nutrition. decanoic acid, also known as capric acid, occurs naturally in coconut oil (8 - 10%) and palm kernel oil (4%). importantly, the published findings show that oral administration of gt, the triglyceride form of decanoic acid, can improve insulin sensitivity and storage and breakdown of fat in animal models of diabetes. notably, in the investigators' recent findings, da could reduce androgen production and alleviate pcos like symptoms in a test-induced pcos rat model. hence, there is a high likelihood that gt can improve the management of pcos without the undesirable side effects that are observed with the thiazolidinediones. the primary aim of the study is to test safety and tolerance of oral intake of gt oil in the form of a non-diary based emulsion (10g of gt per emulsion) in healthy men. this will be a single center study, and the recruitment is expected to happen over a 1-2- month's period.
