The Surprising Truth About MCT Oil

C8 MCT oil converts to ketones in just three metabolic steps

Dr. Jockers explains that caprylic acid (C8) is rapidly converted to ketones, particularly beta-hydroxybutyrate, which cross the blood-brain barrier to reduce inflammation, curb hunger, stabilize blood sugar, and improve insulin sensitivity. He contrasts the three metabolic steps for C8 versus 26 for glucose and 12 for long-chain fats.

"quicker to metabolize than the lauric acid, but still takes a little bit longer to metabolize than the 8-carbon caprylic acid. That metabolizes very quickly. And in the bloodstream, our liver, it goes right into the liver. It's converted into ketones, particularly beta-hydroxybutyrate, and that elevates blood ketones. And that's one of the great benefits of MCT oil is the elevation we get in blood ketones. Those blood ketones get across the blood-brain barrier and they turn off inflammation in the brain and they also turn off hunger and cravings. So they help reduce hunger and cravings and they help you feel energized, mentally clear and energized. They also help to stabilize your blood sugar. So when ketones become elevated in the bloodstream, it stabilizes your blood sugar and improves your insulin sensitivity. That's one of the great benefits of doing like a C8 only MC2L, which is what I use, because it turns quickly into ketones, gets right into the blood-brain barrier, and has this really powerful effect at reducing inflammation in the brain, improving neuronal mitochondrial energy production. So the mitochondria are able to quickly use that as an energy source. In fact, the cool thing about caprylic acid is it only takes three steps to take it from caprylic acid and to turn it into cellular energy. Whereas with something like glucose, right, anything that we're consuming, breaking down into glucose, there's 26 steps that take place before we produce cellular energy."

Ketones balance the glutamate-to-GABA ratio for calm focus

Jockers describes how elevated ketones from MCT oil improve neurotransmitter balance in the brain, enhancing acetylcholine and glutamate receptor sensitivity for better memory and cognition while balancing the excitatory glutamate with inhibitory GABA to prevent anxiety.

"It also supports memory and cognition. This is because it reduces brain inflammation and enhances the receptor activity of all of our different neurotransmitters. So acetylcholine is the main neurotransmitter associated with memory and glutamate as well for cognition, right? Glutamate is kind of like the gas pedal in the brain. When we have good acetylcholine and glutamine sensitivity with the receptors, now, or not glutamine, but glutamate, receptor sensitivity, now we get better cognition, better memory, right? But the other thing is we need to balance the gas pedal of the brain with the brakes. The brakes we call GABA. We got to have the right ratio of glutamate, the gas pedal, the excitatory neurotransmitter, and GABA, the brakes on the brain, the inhibitory neurotransmitter that slows down the brain. We need a really good balance. When people have brain inflammation, blood sugar imbalances, insulin sensitivity, high toxic load, all the different factors that cause brain inflammation, they get overexcited, the neurons do. So they get too much glutamate, not enough GABA. What we want is the right ratio here, balanced ratio, glutamate to GABA. When ketones become elevated and cross the blood-brain barrier, it balances that glutamate to GABA ratio, allowing you to think sharply and quickly, but not being overexcited and having anxiety, but being able to really perform well because we have enough GABA in our system and we have good GABA sensitivity with the neurons."

MCT oil improves mood, stress resilience, and energy

Dr. Jockers explains how C8 MCT oil enhances stress resilience by balancing brain neurochemistry, with research showing reductions in depression, anxiety, and irritability. He notes the mitochondria easily produce cellular energy from ketones with very little oxidative stress or metabolic waste.

"And so they're responding to it, keeping them calm, under control, but performing at a high level. So this is really the best of both worlds. So it supports memory and cognition. It also improves your mood, right, your overall behavior and your ability to adapt to stress. So if you're under stressful, you know, if you're in a stressful period, actually getting ketones in the brain, balancing that glutamate to GABA ratio, reducing overall brain inflammation helps you respond to that stress and be able to handle that stress without breaking and being able to be resilient to that stress. And overall, the quality of your life is really going to come down to your ability to adapt and recover from the stressors in your life. And so the better stress resilience you have, the better you're going to be able to adapt to all the different challenges that you're faced with. And so, getting C8 MCT oil, elevating those ketones, that's one of the best things you can do to help improve your mood. Research has shown it helps reduce depression, anxiety, irritability. We talked about hunger, cravings, right? All of those types of things. And overall, enhances stress resilience. So really powerful there. And then finally, it improves your energy levels, right? Because your mitochondria are easily able to produce cellular energy."

Dosing protocol to avoid disaster pants

Practical dosing guidance for MCT oil: start with half a teaspoon to test tolerance, work up to a teaspoon per meal, and cap at one tablespoon per meal (two to three times daily). Jockers recommends the oil form over capsules for better dosing and value, and notes it can be added to coffee or taken during fasting windows.

"And so I don't recommend just taking MCT oil and chugging it. It comes in an oil form. I do recommend getting it in the oil form as opposed to the capsule because you get a better clinical dose and you get better value. You can get more of the oil for less money when you get it in the actual oil form. But I recommend starting with roughly a half a teaspoon to a teaspoon of a dose. Why? Because if you're really sensitive, you have a real sensitive gut, taking too much too quickly again can cause diarrhea and so start with a half a teaspoon and see how your body tolerates that i typically recommend taking it with meals but you can definitely put it in your coffee for example or take it during your fasting window and that will actually help you fast more comfortably and fast longer will it break your fast technically to some degree because it's got calories, it will break your fast."
