MCT Oil
Also known as: Medium-chain triglycerides, C8 caprylic acid
MCT oil provides medium-chain fats that are absorbed and used for energy differently than most dietary fats. It is commonly used in coffee, shakes, or ketogenic-style routines as a calorie and energy source. Evidence for benefits beyond calories is limited. Digestive upset is common at higher amounts, so starting low is widely suggested.

Often about absorption or timing rather than danger — separating doses is common. This list is not exhaustive.
🧭 Caution level
- Evidence not fully source-reviewed yet
Caution level is an informational summary of commonly discussed caution categories and doses — not a safety rating, approval, or medical advice. Low caution does not mean safe for you.
