NOW Foods Grapefruit Oil is a 100% pure cold-pressed essential oil expressed from the peel of Citrus paradisi — a bright, fresh, slightly tart citrus oil beloved in aromatherapy for its uplifting, energizing, and appetite-modulating effects. Grapefruit oil is rich in d-limonene and other monoterpenes that give it a clean, invigorating citrus aroma associated with increased energy, focus, and positive mood. Research has examined inhaled grapefruit oil for its effects on appetite and sympathetic nervous system activation, with some studies suggesting it may help reduce food cravings and support weight management programs when used aromatically. NOW Foods' Grapefruit Oil is cold-pressed without heat to preserve the full volatile aroma profile. GC/MS tested for purity. Cold-pressed citrus is photosensitizing — avoid sun exposure after topical use. Not for internal use.
