MCT Oil — Frequently Asked Questions

C8 (caprylic acid) is the most ketogenic MCT — it converts to ketones approximately 3x faster than coconut oil and is the preferred choice for cognitive benefits and rapid energy. C10 (capric acid) converts more slowly but may offer broader antimicrobial properties and sustained energy. A C8+C10 blend provides the best of both, though pure C8 products are optimal for maximum ketone production.

MCT oil is rapidly absorbed and can overwhelm bile salt recycling in the small intestine, drawing water into the gut and causing cramping, nausea, or diarrhea. This is almost always a dosing issue — starting with 1 teaspoon and increasing by 1 teaspoon every 3-4 days allows your digestive system to adapt. MCT powder is gentler because the acacia fiber carrier slows absorption.

No. MCT oil produces ketones regardless of your dietary carbohydrate intake because it bypasses normal fat digestion and goes directly to the liver for ketone conversion. You will produce measurable blood ketones (0.3-0.5 mmol/L) even on a standard diet. However, ketone levels will be higher if combined with carbohydrate restriction.

Morning is the most popular time — added to coffee or a smoothie for sustained mental clarity. For appetite suppression, take it 15-30 minutes before meals. For exercise, take it 30-60 minutes before a workout. Avoid taking large doses late at night, as the energy boost may interfere with sleep. Always take with or shortly before food when starting out to minimize GI issues.
