WHAT IT DOES
Concentrated medium-chain fats that your liver converts directly to energy, while helping absorb fat-soluble supplements.

DOES IT WORK?
Same as MCT oil from coconut, just without specifying the source. MCTs are genuinely useful both as a carrier oil (improves fat-soluble vitamin absorption) and as a standalone energy supplement. Research supports modest benefits for energy, satiety, and ketone production.
