WHAT IT DOES
Medium chain triglycerides derived from palm kernel oil. Same metabolic benefits as coconut-derived MCT, just a different source.
🏆

DOES IT WORK?
Functionally identical to coconut-derived MCT oil. Gets rapidly converted to ketones for energy. In supplements, typically used as a carrier oil for fat-soluble ingredients. Therapeutic benefits only show up at 5-15g daily, and most supplements don't provide that much.
