Jarrow Formulas L-Carnitine 500 mg - Important Cofactor for Energy Production (ATP) from Fats - Antioxidant Supplement for Energy Production - 100 Veggie Caps (Pack of 12)

Great product for cardiac health

This is the best form of carnitine according to Dr Sinatra. I take this for severe Myalgic Enephalomyelitis. I'm housebound and 95% bedbound, though my illness is now slowly improving. It really helps my heart problems at a dose of around 2.5 grams a day. It has improved the time I can stay upright hugely; from 20 minutes a day to 40 or so. Ubiquinol gave me another 10 too. Dr Sinatra explains that ubiquinol/CoQ10 works synergistically with carnitine, as does ribose and magnesium. He calls them the 'awesome foursome' of cardiac health. The name carnitine is derived form the latin `camus' for flesh as carnitine was first isolated form meat sources. Nutritionist Robert Crayhon, author of The Carnitine Miracle, explains that strictly speaking, carnitine is not an amino acid and that carnitine does not in fact contain the amino group (NH2). He explains that carnitine is a coenzyme, a water-soluble vitamin-like compound. And that carnitine is similar to choline, one of the B vitamins-and, like various B vitamins, carnitine helps us turn food into energy. More specifically, it is essential for the burning of long-chain fatty acids. The heart depends on adequate concentrations of carnitine for normal heart function. * The primary role of carnitine is to help transport fatty acids into the energy producing units in the cells - the mitochondria, where they can be converted to energy. This is a major source of energy for the muscles, including those of the heart. Carnitine increases the use of fat as an energy source. * Carnitine is useful in clearing the bloodstream of ammonia and aids in creating glycogen, used to store essential glucose. Carnitine transports waste products out of the mitochondria, thus ensuring that toxic metabolic waste products do not accumulate. Carnitine reduces the accumulation of lactic acid, which is responsible for the burn felt inside the muscles with exercise. * Carnitine can help to prevent muscle atrophy. * Carnitine protects the heart from damage when a heart attack or a spasm cuts off the oxygen supply. Recent research has shown that carnitine can aid in recovery after a heart attack. Michael Murray N.D., author of `The Pill Book: Guide to Natural Medicines' writes, `Subjects taking carnitine showed significant improvements in heart rate, blood pressure, angina attacks, rhythm disturbances, and clinical signs of impaired heart function compared to the subjects taking placebo.' * Low thyroid function may indicate a need for carnitine to help overcome low energy levels and the tendency to gain weight. * Carnitine can improve insulin sensitivity in those with type 2 diabetes. * Kidney dialysis rinses away amino acids, causing weak, tired condition, which is threatened by high triglycerides. Carnitin supplements may be advisable in such situations. * At doses of 1 - 3 g carnitine reduces blood triglycerides. (As the LEF website explains, `Carnitine combines with enzymes found in the mitochondrial membrane to transport fatty acids into the interior of the mitochondria, where they are oxidized to provide fuel for the generation of energy. In the absence of carnitine, fatty acids are not oxidized, but, instead, are transformed into dangerous triglycerides.') * Carnitine is an antioxidant and enhances the effectiveness of antioxidant vitamins C and E. Carnitine is synergistic with pantethine (vitamin B5). Carnitine is manufactured by the body if sufficient amounts of iron, vitamin B1, vitamin C, niacin, vitamin B6, lysine, and methionine are available. Food sources of carntine include meat, poultry, fish, and dairy products are the richest sources of L-carnitine. Grains, fruits, and vegetables contain little or no carnitine. Robert Crayhon points out that due to high consumption of red meat, the Stone Age hunter probably got at least 500 mg of carnitine a day, and possibly as much as 2 grams. Today the average carnitine intake is estimated at a mere 30 to 50 mg a day. Strict vegetarians consume practically no carnitine. L carnitine is generally not well absorbed, and is best absorbed on an empty stomach. There are several different forms of carnitine; * L carnitine fumarate is absorbed at a slightly higher rate than pure L carnitine and L carnitine tartrate. It is stable enough to be available in capsule form. L carnitine fumarate has a double effect as the fumarate is a free radical scavenger and also plays a part in the krebs energy cycle. * Pure L carnitine draws moisture and so is not suitable for use in capsules and tablets. It is commonly used in liquid carnitine products and pure carnitine powders. It has a very mild taste when mixed with water and is a good choice of carnitine. * For angina and other cardiovascular applications, a new form of carnitine known as L-propionylcarnitine appears to be the most effective form of carnitine, although it may also be the most expensive and difficult to source. (Look for products labelled Glycocarn.) * L carnitine tartrate is an adequate form of L carnitine. When mixed with water it has an unpleasant tart taste. L carnitine is thought to be one of the safest nutritional supplements on earth, according to Dr Sinatra. This supplement is really essential if you have serious heart problems, in my opinion.

Superb Supplement

Over the past year, I started learning about the different forms of carnitine. I personally found the tartrate form to be exciting as it yields so many health benefits. I take 1500mg every day and feel great. Here is some information about this supplement that I found to be very helpful: L-Carnitine Tartrate contributes to the functioning of metabolism. It can improve vitality, help prevent heart problems, and help slow down the aging process. Whenever an organism needs energy, L-Carnitine plays an important role. It transports fatty acids into the mitochondria. L-Carnitine mainly increases the rate at which fat is burned. This tends to reduce fat and build up lean muscle mass. (I find this very exciting!)L-Carnitine has no harmful side effects and poses no known risks. L-Carnitine is recommended for: expectant mothers, small children, athletes, smokers, people who have above-average stress levels in their lives, people who suffer from heart disease and diabetes, or seniors who would like to preserve and promote their health and mental fitness even at an advanced age. Also of use for people who are quickly exhausted or anyone on a calorie-reduced diet for weight loss. Vegetarians and vegans will profit a great deal from L-Carnitine as a dietary supplement. Vegetarian expectant and breast-feeding mothers are strongly advised to take additional L-Carnitine in order to avoid deficiencies and not to endanger the healthy growth of their children. Muscle Benefits: *Increases strength and endurance *Relieves physical and mental fatigue *Promotes and maintains new development of muscle mass *Reduces muscle injuries and sore muscles *Accelerates regeneration Heart Benefits: *Increases cardiac output *Lowers the heart rate under stress *Reduces the intensity of cardiac infarction *Reduces symptoms of heart failure, angina pectoris Immune System Benefits: *Supplies energy to immune cells *Increases activity of immune cells under stress *Doesn't strain the immune system Brain Nerve Benefits: *Slows aging of brain, dementia, Alzheimer's disease *Improves cognitive abilities like concentration, memory, and ability to learn *Accelerates renewal of tissue Liver Benefits: *Improves liver function *Reduces problems of fatty liver *Accelerates renewal of liver tissue Sperm Benefits:(threw this in for the men reading this) *Improves activity of sperm *Enlarges amount and number of sperm *Increases fertility of sper

L-carnatine is a God-send!

Much better price than through my pharmacy. Excellent product. One of the few OTC drugs that works better than prescription ones. Completely took away all back & leg cramps that I've been suffering with for years. My doctor recommended it, 1 tablet 2x a day

Too bad – it sounded so good

A warning is needed that this product may have harmful side effects for people on low-thyroid medication. It appears to block the effect of thyroid boosting medications. In my case, it immediately started weight gain, which continued until I stopped taking the supplement. At that point the weight gain was immediately reversed. You can find some information on the web if you search for carnitine side effects hypothyroidism. Too bad - it sounded so good, but it's not good for some of us

Best I've found

I have Graves disease. L-carnitine has done wonderfully to control it. I took 3000mg for about a year but now only need 1500mg as my thyroid levels are much better. I took the tartrate form of l-carnitine but have found out that L-carnitine is not stable in dry form by itself so that's why it's either tartrate or fumerate form. That's where these liquid caps come in. It contains glycerin (glycerol is a component of fats in our bodies) but that seems better for me than tartrate (I have terrible issues with many foods and chemicals and apparently tartrate is common in wine, grapes, avocados and apricots all of which I can't have much of). I looked into other liquid forms of Carnitine but this one is cleanest in my opinion as it has no flavorings or stevia (for people like me that have a problem with that herb). It's easier than carrying around liquid in a bottle too. I'm really glad this product is available

After 1 Month…

This product was recommended for the keto way of eating (woe). I have been taking them for 1 month. I'm not sure if they are working but I have lost 26 pounds and my energy level is up. Could be a combination of keto and this supplement

Get up and GO

I swear by L Carnitine to make me feel normal. It's not a pain med but it has a similar effect. Aches and pains seem to disappear and it makes me feel like getting up and doing what I need to do with a sense of tirelessness. Very good stuff. Highly recommended

Fast weight loss

I take 2 tablets of these (1 in the morning and 1 when I get home from work). I lose weight very fast without even doing anything. When I don't take these I notice that i don't lose as much weight. This is a very good product

perfect for hyperthyroid cat (NOT for HYPOthyroidism in anyone)

I bought these liquid capsules for my cat, who is hyperthyroid. They have helped her tremendously. Before finding these, I had been using powder from a regular capsule, but I could never get enough of it into her. Each of these liquid capsules has the right dose (500mg.), and no other ingredients or flavorings. I cut open the top of the liquid capsule and add the (gooey) liquid to her other supplements and give them to her with a syringe. In just under a month, she has gained weight and become more active and playful. (She is sixteen years old.) You should NOT be using l-carnitine if you suffer from hypothyroidism, but it is a godsend if you have hyperthyroidism -- which makes absolute sense. (Look up "Benvenga 2001" for results of l-carnitine testing on hyperthyroid women.
