Its composition is high in bioactive ingredients (such as terpenic acids and polyphenols) which have proven anti-inflammatory, antioxidant, cardioprotective, chemoprotective and antimicrobial properties. The aim of this study is to determine the effect of Mastiha oil in adults with Hypetriglyceridemia. 100 participants will be allocated to two groups, (50 in intervention group and 50 in control group). Mastiha oil will be provided in the form of soft gel capsules to the intervention group, whereas the control group will not consume the capsules.
