Randomized, controlled, triple-blind clinical trial with three parallel arms based on the product consumed (low-dose experimental product, high-dose experimental product, and placebo product) and conducted at a single center to measure the efficacy of a product (Xanthigen®) on overweight or obesity during 16 weeks of consumption.

Participants who meet the inclusion criteria will be included in the study. They will be randomized into three groups, each receiving a dose of the experimental product: 0mg (placebo), 300mg, or 600mg for 16 weeks. The treatment will be administered as a single daily dose in the morning on an empty stomach.

All participants will undergo the same assessments as the active-treatment groups, including anthropometric measurements, physical activity monitoring, and blood tests to evaluate metabolic and biochemical variables. Participants will be asked to maintain their usual dietary and physical activity habits throughout the study.
