MCT Oil (Medium-chain triglycerides)

MCT Oil

Snapshot

MCT Oil is a supplement of medium-chain triglycerides (C6–C12 fatty acids) that are rapidly absorbed and utilized for energy, supporting metabolism and cognitive function.

 

---

What is MCT Oil?

MCT Oil consists of saturated fatty acids of 6–12 carbon chain length, primarily caprylic (C8) and capric (C10) acids, derived from coconut or palm kernel oil.

---

Where It Comes From

Extracted and fractionated from coconut or palm kernel oil, MCT Oil is refined to concentrate medium-chain fatty acids and remove long-chain triglycerides.

---

Key Nutrients & Compounds

Provides C6–C12 MCTs that bypass lymphatic chylomicron transport and are directly delivered to the liver for rapid beta-oxidation, producing ketones for brain fuel.

---

Health Benefits

MCT Oil supports quick energy supply; may enhance cognitive performance; promotes satiety and weight management; and can aid ketone production in low-carb diets.

---

Recommended Dosage

Start with 1 tsp (5 mL) daily and gradually increase to 1–2 Tbsp (15–30 mL) per day; divide doses to minimize digestive upset.

---

How to Use It

Add to coffee, smoothies, salad dressings, or take straight; use on an empty stomach or with meals to optimize absorption and ketone production.

---

Who Should Use It?

Suitable for individuals following ketogenic or low-carb diets, athletes requiring quick energy, or those seeking cognitive support and metabolic flexibility.

---

Possible Interactions or Cautions

May cause gastrointestinal discomfort or diarrhea at high doses; start low and titrate slowly; caution in individuals with fat malabsorption disorders.

---

Final Thoughts

MCT Oil is a versatile, fast-acting energy source that can enhance mental clarity, support metabolic health, and facilitate ketone production.
