The goal of this clinical trial is to compare de effect of vitamin K2 in young adults with overweight or obesity. The main questions to answer are: What is the effect of Vitamin K2 supplementation on methylation, serum concentration of ucOC, cOC, Gas6, leptin, inflammatory markers, cardiometabolic risk factors, and cardiovascular risk in overweight or obese young adults? Participants will be assigned to one of two intervention groups where they will consume Vitamin K2 100 µg per day or cornstarch 500 mg per day for 90 days. If there is a comparison group: Investigators will compare the supplementation group (Vitamin K2) with the placebo group (cornstarch) to see if vitamin K2 supplementation modifies methylation, increases serum vitamin K, osteocalcin, growth arrest-specific 6 protein serum concentration, decreases serum leptin concentration, inflammatory markers and reduces cardiometabolic risk factors and cardiovascular risk.
