Like 99% of supplements, waste of money in my opinion.

If you list your diet/exercise I'm sure I can find pointers 100x more significant than L-carnitine.

On the male side, I didn't see any noticeable effect with l-carnitine. YMMV.

Yeah you'll notice a difference, but this only b/c you are already quite lean. It'll help give you that extra edge. I have used it on and off since I was 16, and take 1 cap (whihc may or may not be the full dose, idk) on an empty stomach in the morning before cardio. It works, and aside from assisting in fat burning, it's probably healthy for you too. Give it a shot. I've used various brands, but I hear that liquid L-carnatine is best. I've only used caps though and they still work for dropping that last couple percentages of bodyfat.

Hope this helps and good luck.

Naturally people have a fairly large amount of l-carnitine floating about so supplementation would require a large amount of orally taken l-carnitine to be taken and absorbed. To realistically get concentrations higher from supplementation the l-carnitine would have to be injected along with a dose of insulin, injected insulin in all likelihood as I'm not sure that high GI carbs will cut it.

This may be anecdotal but I found that taking a liquid carnitine supplement right before working out seemed to help me lose weight more quickly. However, it wasn't the only thing I was doing so my results cannot be directly attributed to the carnitine.

If you're really curious, you might just get a bottle and try it for a month to see if it makes a difference. Though if you say you are "quite lean" then it might not help as much as it helped me.

Something else I did that I think helped me burn fat more efficiently was to work out in a semi-fasted state. By semi-fasted, I mean no food (and especially no carbohydrates), but having had a scoop of coconut oil in my coffee before the workout. I don't know the 'science' behind it, but I had read that coconut oil promotes the use of fatty acids as the energy source to fuel the workout. Combine that with high intensity interval training, and you may see results without needing the supplement.

you are lean but want that extra mile for personal preference(you want the somali skinny) dont eat. its the quickest way to drop weight i know of. And its cheap. is it right? i doubt it. But is L-carnitine right? i doubt it. why not focus on healthy as a personal preferance?

I use it for a few days to kickstart things when I restart a low carb diet. It works pretty well for that, but it doesn't help me to lose weight.

When you say you know the science, I'm not sure if you mean it will or won't work.

Here's a great blog about it.

To lose those last 5, I'd look at Quilt's leptin reset protocol.

In short, eat a high-protein and fat breakfast within an hour of waking; don't snack; and don't eat after dinner.

Whenever Im trying to get really lean, (usually in the summer) I usually hit a stalling point before I hit my target BMI. Other than a carb re-feed the only other thing Ive noticed working for me is I will start adding in optimized carnitine first thing in the morning with my steak and eggs.

I've been using l- carnitine for 2 months now, and I don't think it's actually doing anything anymore- and I'm not sure it ever did. The first 2 weeks I felt quite warm and thirsty (drank a lot of water) and was sweating a bit more than usual. Since then, I haven't noticed anything more. I started at 2000 mg and upped it to 3000.

Funny thing is, I'm hesitant to stop taking it in case it did do something... Which means it's time to stop and see what happens. Expect a follow up comment in a month or so :)

(ps- female, 31, started taking this when I big-upped my fat intake)

Acquiring regular amounts of L-carnitine doesn't trigger any kind of harmful effects on your entire body. Typically, the suggested dose of L-carnitine is absolutely not greater than 5 gr daily. This serving really should be tightly implemented. A lot of events were documented in which substantial quantities of L-carnitine ended in some kind of problems. As a result, the particular chances of L-carnitine unwanted effects can be infrequent although not zero. Upcoming is certainly a report of available complications of L-carnitine.

Lots of people state that they are energised soon after getting L-carnitine. Consuming it during the night could potentially cause issues with sleeping.

Acquiring a lot more than given dosage amounts of L-carnitine normally leads to diarrhoea in addition to a visible increased desire for food.

A lot of individuals with lasting prescription of L-carnitine report of 'fishy' odour of their body. A few of them come up with skin situations for example soreness, itchiness and even skin area breakouts.

If you're a sufferer of peripheral vascular disorder, diabetes mellitus, elevated blood pressure, kidney condition and even cirrhosis, you must tell your doctor if perhaps he or she is suggesting you L-carnitine, since it is considered to interact with the medicines regarding the exact same.
