Outcomes
Primary Outcome Measures
Measurement of circulation
Measurement of dermal microcirculation using "O2C, Lea Technik":
Relative peripheral blood flow (LDF)
Venous oxygen saturation (SO2 ven)
Relative amount of haemoglobin (rHb). Delta change of dermal microcirculation from baseline to end of supplementation is investigated. Addi-tionally, the delta change of dermal microcirculation from baseline to end of supplementation post-prandial is determined, which means the evaluation of postprandial effects on reactive hyperaemia index after glucose load.
Secondary Outcome Measures
Measurement of glucose related biomarker
Measurement of Biomarker HOMA-Index, HbA1c at baseline and end of supplementation under fasting conditions.
Questionnaire on fatigue and vigor
Questionnaire on fatigue and vigor
Monitoring of adverse effects
Reporting of adverse effects to evaluate tolerability
Measurement of endothelial function using "EndoPATTM, Itamar"
Measurement of endothelial function using "EndoPATTM, Itamar"
Reactive hyperaemia index (RHI and lnRHI)
Arterial stiffness (AI75) Delta change of endothelial function and arterial stiffness from baseline to end of supplementation is investigated. Additionally, the delta change of endothelial function from baseline to end of supplemen-tation postprandial is determined, which means the evaluation of postprandial effects on relative hy-peraemia index after glucose load.
Measurement of ox LDL

5. Study Description
Brief Summary
Aim of the study is to investigate long-term effects of CarelessTM, a Mangifera indica fruit powder on microcirculation and endothelial function after supplementation of 4 weeks. Effects will be investigated with 100mg and 300mg CarelessTM and compared to placebo.
Detailed Description
Aim of the study is to investigate long-term effects of CarelessTM, a Mangifera indica fruit powder on microcirculation and endothelial function after supplementation of 4 weeks. Effects will be investigated with 100mg and 300mg CarelessTM and compared to placebo.
To describe targeted parameter, cutaneous microcirculation will be measured at 1 mm depth as well as flow mediated endothelial function at the beginning and end of supplementation, each. Furthermore, the parameters will be determined postprandially 1 hour after glucose loading. Additionally the influence on the glucose metabolism, as well as on body weight and body fat will be documented.
