Brief summary

Type 2 diabetes mellitus (DM2) is a growing social health problem world-wide, in particular with respect to its contribution to cardiovascular disease. The progressive increase in prevalence of DM2 has reached epidemic proportion and is a major cause of morbidity and mortality in all populations around the world. Conventional stepwise treatment of DM2 generally focuses on controlling blood glucose concentration. However, the risk for side-effects associated with the use of pharmacological intervention often delays initiation of therapy, with the potential implication on worsening morbidity and mortality from complications. On the other hand, non-pharmacological intervention in the form of dietary restrictions, exercise and weight loss, is safe but often difficult to accomplish. The availability of nutrients that affect glucose and lipid metabolism would provide an important practical tool to establish early intervention in newly diagnosed DM2 and perhaps even in patients who are only at risk for DM2. The investigators have recently obtained preliminary data on beneficial effects of combined supplementation of lycopene and isoflavones on glucose metabolism of normoglycemic volunteers with insulin resistance. This clinical trial will explore the role of isoflavones and lycopene dietary supplementation in the improvement of glucose metabolism of patients at increased risk or with established but mild DM2. The overall hypothesis is that supplementation of laflavon, provided as a new formulation that increases bioavailability of the individual components (Laflavon CamMedica contains 7 mg of Lycopene and 50 mg of Soy Isoflavones), determines improvement in glucose tolerance and insulin resistance of patients with the metabolic syndrome and also reduces HbA1c in patients with mild DM2.

Interventions

DRUGRandomized pills either containing combination of lycopene and isoflavones (dietary supplements) or Placebo to be taken for 12 weeks

After the screening and OGTT, the treatment group each subject will be in is decided by randomization. Neither subject nor the researchers will be allowed to choose which group a subject is assigned to. A single patient/subject cannot be assigned more than 1 allocation number. Each subject will be assigned randomly (like drawing straws) to receive either on the pills containing the combination of 6mg lycopene and 50mg isoflavones or placebo. Each subject has a 1 in 2 chance of receiving one of these treatments. The subject are advised to take one capsule of Laflavon/Placebo by mouth daily for 12 weeks.

OTHERScreening

Volunteer will be screened as an out patient with a history, physical examination, baseline fasting plasma glucose or A1C, creatinine, AST/ALT, TSH. We may utilize the lab results of the subject available upto 3months prior to the consent date. Pregnancy tests will be performed for female candidates. Information of the level of physical activity, diet, supplements and medications will be obtained.

OTHEROGTT

OGTT will be done after the screening at Baseline and at the completion of the 12 weeks of taking the supplements by the subject.

OTHERAnthropometrics and Blood pressure

Measurements of height, weight, hip, waist and Blood Pressure are done before and after 12 weeks of taking the supplements.

OTHERBlood Drawing

The blood will be drawn at the baseline and at the completion of the 12 weeks of taking the capsules of laflavon /placebo.
