Clinical Trial Summary

Plant polyphenols have demonstrated the ability to ameliorate metabolic alterations induced by overweight and obesity, both in cellular and animal models, where most therapeutic approaches have failed. These have demonstrated the ability to improve appetite sensation, leading to improved body weight control, in addition to reducing fat accumulation and improving plasma glycemic and lipid profiles, as well as inflammatory process and vascular dysfunction. The plant polyphenols on which the extract to be studied will be based will be hibiscus and lemon verbena. A randomized controlled trial will be carried out in overweight or obese subjects from the province of Alicante. An electronic randomization will be carried out based on a two-branch design, therefore, there will be a control group (no intervention) and an experimental group (nutraceutical intake). Participants will have to ingest the nutraceutical for 3 months, as well as attend the agreed visits. Different satiety questionnaires, circulating parameters measured in capillaries (cholesterol, triglycerides and glucose), blood pressure and body composition measured by bone densitometry (DXA) will be collected. All variables will be measured at 4 different time points (baseline, 30 days, 60 days and 90 days). All these will be analyzed as a function of time; at the beginning and end of each intervention (intra-group analysis), as well as comparing the control group with the experimental group (inter-group analysis). A multidisciplinary team formed by physicians, nurses and nutritionists will be involved.

Intervention

Dietary Supplement:
• Metabolaid(R)
The participating subjects will have to follow the intake of the nutraceutical for 3 months, as well as attend the stipulated visits. Participants will be given a register to control their daily intake of the nutraceutical. They should not change their daily habits. The nutraceutical has been elaborated by Monteloeder, S.L. It is a combination of Hibiscus sabdariffa flowers and Lippia citriodora leaves. The dose that the participants of the experimental group will receive will be 300mg plus 20mg of microcrystalline cellulose. The product is presented in an unflavored capsule, it is a reddish-brown powder with a characteristic odor and a slightly bitter taste. The manufacturing date of the product was 01/12/2022 and the expiration date was 30/11/2024.
• Nutraceutical placebo
The participating subjects will have to follow the intake of the nutraceutical for 3 months, as well as attend the stipulated visits. Participants will be given a register to control their daily intake of the nutraceutical. They should not change their daily habits. Nutraceutical placebo contains microcystalline cellulose (185mg) and maltodextrin (185mg).
