Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Experimental group (Lippia citriodora + sabdariffa); Consumption for 60 days of Lippia citriodora 325 mg + Hibiscus sabdariffa 175 mg. Two capsules per day will be consumed thirty minutes before breakfast orally for 60 days.	Dietary supplement: Dietary supplement consumption; The experimental product consumption time was 60 days and the control consumption time was 60 days. Each subject must consume both products, with a washing period of 30 days.
PLACEBO_COMPARATOR: control group Placebo (sucrose); Two capsules per day will be consumed thirty minutes before breakfast orally for 60 days.	Dietary supplement: Dietary supplement consumption; The experimental product consumption time was 60 days and the control consumption time was 60 days. Each subject must consume both products, with a washing period of 30 days.
