 L-carnitine is a amino acid that can boost your cognitive performance, increase your energy levels, improve your focus and attention, and even improve your physical performance. But is it really beneficial and should you really consider supplementing it? Well, let's find out. Hi friends, welcome back to the channel. My name is Greg and I'm a certified brain health professional. On this channel, we help professionals achieve peak performance by unlocking their full brain potential. If this interest you, then subscribe below and join our amazing community. Today, we are going to talk about L-carnitine. We are going to talk about the benefits, the side effects, the synergies, dosages, and at the end of the video, I'm going to tell you who should consider supplementing L-carnitine. So if you're ready, let's just begin. Now L-carnitine is an amino acid that is produced in the liver from two other amino acids. One is lysine and the other one is metionine. Now L-carnitine has been primarily used for reducing fatigue, for improving sperm quality, and for improving male fertility. But more recent research shows that it may be a potent cognitive enhancer. But is it really? By the way guys, have you ever tried L-carnitine? If you did, did you experience any kind of benefits? Let me know in the comment section below. So let's check out the benefits. The first benefit is that it may improve memory and learning. So there was one study published that showed that yes, L-carnitine can improve memory and learning. But the study was done on people who suffer from cognitive decline. In particular, they had Alzheimer's disease. And they took a very, very high dosage of L-carnitine, about 10 grams per day, which is five times higher than it is the recommended daily dosage. But they have noticed an improved cognitive function. So if you suffer from cognitive decline, if you suffer from dementia, then it may be beneficial to supplement L-carnitine. However, before you do it, do consult your doctor. But what if you are a healthy individual? Can you expect any kind of benefits on your memory? Now if you look at the famous Reddit survey, you're gonna figure out that L-carnitine scores quite low on the ranking of all the tropics for memory improvement. So I think it is very unlikely to get any kind of positive benefits on memory and learning if you're a healthy individual. But what about depression? Because that's another benefit of supplementing L-carnitine. While one study showed that if you take two grams of L-carnitine per day two times, so together four grams per day, the symptoms of depression can decrease. But there is one problem. The study was done in people who suffer from a nervous system disorder, which is the result of severe liver disease. And since L-carnitine is synthesized in the liver, of course supplementing it benefited them. So if you don't have a severe nervous system disorder, it's really hard to expect any kind of benefits on depression. Or at least let's say like this, we don't have any studies that show those effects. Now how about improved energy levels? Well yes, L-carnitine can increase glucose and creatine levels and because of that it can improve or increase your energy levels. And because of that it can also improve your physical performance. Now what about attention? Yes, well one study found that kids who have ADHD and were given L-carnitine have noticed an improved attention. But there was no other studies on healthy individuals, so it's really hard to say if L-carnitine can increase your attention or not. But we know that L-carnitine can be neuroprotective and it may help with fat loss, physical performance and also improve the sperm quality. Yes, the studies show pretty weak effects, but the effects were noticeable, so you can expect those benefits. By the way guys, do you want to know how well does your brain perform? If yes, go through our free brain assessment, link in the description below and get your brain performance score. Now what is the optimal dosage of L-carnitine? Well there are two popular types of L-carnitine available in the market. If you want to boost your cognitive performance, then taking L-car a subtle L-carnitine seems to be the best form and for that the recommended dosage is about 600mg to 2.5g per day. Now if you want to improve your physical performance, then take a dosage of 1g to 4g of L-carnitine L-char-trade, which is the second type of L-carnitine. For best results, I recommend taking this amino acid with some carbs. Now how about synergies? Does it make sense to combine L-car or L-carnitine with some other nitropics? You can combine it with alpha-depoic acid, which is a very strong antioxidant, or coenzyme Q10, which is another very strong antioxidant. In addition, you may combine it with choline, because choline increases L-carnitine in the position of muscles and you can learn all about it in this video up here, and you can even combine it with caffeine, because this will even more boost your energy levels and work as a strong stimulant. So if you decide to take L-carnitine, consider supplementing it with those mentioned nitropics. But is L-carnitine really safe? What about these side effects? Well the first thing you need to know is that there are non-responders to L-car. So if you're one of those, then it doesn't make any sense to supplement L-carnitine. The second thing is that vitamin C deficiency can impair synthesis of L-carnitine. So you need to ensure high levels of vitamin C, which you can get for different kinds of foods. You can drink a lemon juice in the morning, or just take a vitamin C supplement. All of those options work well. It also may cause odd smell, which, yeah, is sadly true. In addition, people report the following side effects, nausea, vomiting, and diarrhea. But at very high dosages, at about 3 grams per day. So if you want to avoid those side effects, then take a lower dosage as I recommend to you before. Lastly, and this is very important, within 24 hours of supplementation L-carnitine would increase the levels of TMAO in your body, which can increase the risk of heart disease. So if you are at a risk of heart disease, then it's not really recommended to take L-carnitine. By the way, guys, if you like this video, please press the like button below. So just before I tell you who should consider supplementing it and who not, where can you buy it? Well, below in the description, you're going to find some links to my favorite entropic supplement that contains L-carnitine. But if you want to just buy it as an individual compound, you're going to find some links as well that lead to top quality entropic sites or entropic stores where you can buy L-carnitine or L-car. So just check them out if you're interested. So who should really take L-carnitine? Now in my opinion, people who suffer from cognitive decline, maybe they have dementia, they have Parkinson's disease, they have Alzheimer's disease, they would probably benefit from it. But if you're one of those, then of course I suggest you consult your doctor and you discuss the supplementation of L-carnitine or L-car in this case. So people who suffer from liver or kidney disease probably will benefit from supplementing it. But what if you're a healthy individual? What if you're a young professional and want to improve your cognitive performance? Well it is very unlikely that you have two low levels of L-carnitine in your body and therefore you probably won't gain much from supplementing it. But if you want to try it out, then take a low dosage. I recommend 500 milligrams to maximum one gram per day for a short period. That's it for a couple of weeks or maybe one month and see how this works for you. Of course if you get L-car in a more complex and tropic supplement, then that's fine especially if there's a low dosage inside. But probably if you take it as an individual compound, you won't get that much of a benefit. Luckily there are better tropics available in the market, they're more potent and even safer for supplementation. And if you want to learn all about them, check my next video up here. Thank you guys for watching and I hope to see you soon again.
