L-Carnitine And Its Health Benefits

best l-carnitine

L-Carnitine is an amino acid produced from lysine and methionine. Amino acids are building blocks of proteins. This is the main reason why L-Carnitine is useful in gaining muscle mass.L

-Carnitine is naturally produced in your body, but supplements are sometimes needed to elevate low levels or as replacement supplements for people with strict diets and premature or low-weight infants.Other reasons for lowered L-Carnitine levels are medical procedures such as hemodialysis in kidney disease patients which use up L-Carnitine.

Genetic disorders or side effects of some drugs such as valproic acid can also cause a decrease in L-Carnitine.

Aside from L-Carnitine deficiency, L-Carnitine offers a wide range of health benefits. Although most claims need further research, the following are the conditions on which L-Carnitine may have positive effects.

  • Fat And Weight Loss

L-Carnitine is usually marketed for weight loss. Studies show that taking it orally can help increase muscle mass, and reduce fat mass and fatigue. It can also suppress appetite and give you aerobic resistance and strength for more efficient calorie burning.

  • Muscle Mass

L-Carnitine is perfect for packing on muscles in weightlifters and hard gainers. It also helps strengthen your muscles which allow you to lift heavier weights and so get bulkier.

  • Heart Conditions

Studies suggest that L-Carnitine can help reduce the symptoms of angina and heart failure. It can also assist in the recovery from and prevent the recurrence if taken immediately after a heart attack.

  • Peripheral Vascular Disease (PVD)

PVD is a condition where there is reduced blood flow to the legs due to hardened arteries. It can cause pain and stiffness. Several studies have shown that L-Carnitine helps alleviate the symptoms and improve the mobility of patients with PVD.

  • Diabetic Neuropathy

This occurs when dangerously high glucose levels in the blood cause nerve damage, especially in the limbs.This can cause pain, numbness or even paralysis.Some preliminary investigations suggest that L-Carnitine help in reducing these symptoms and may also possibly contribute to nerve regeneration.

L-Carnitine can also help type II diabetes patients by improving glucose oxidation, storage, and uptake.

  • Alzheimer’s Disease And Memory Impairment

Several studies show that L-Carnitine can delay the progression of Alzheimer’s disease, relieve senility and dementia-caused depression and help improve, memory in older people.

  • Male Infertility

Experiments have concluded that L-Carnitine can increase sperm count and motility, as well as help in solving erectile dysfunction.

  • Brain Function

L-Carnitine has been known to protect you from both stress and age-related brain damage and improves cognitive functions.

How To Choose The Best L- Carnitine Product

best l-carnitine

In order to assist you in selecting an L-Carnitine product, here are five characteristics you should look for. Not only will these narrow down your choices but also ensure you get the most out of the product you will purchase.

  • 1. Purity And Concentration Of Product

First on this list is the purity of the product. Opt for ones that give you a relatively pure concentration over those that contain fillers or extenders. This way, you get the full benefit of the supplement and also makes for money well spent.

  • 2. The Form Of L-Carnitine

When it comes to form, there are two ways to look at L-Carnitine: chemical form and physical form.Its chemical forms include Acetyl-L-Carnitine which is argued to be the most effective but also the most expensive. Another is Propionyl-L-Carnitine which helps raise Nitric Oxide (NO) levels in the body for improved circulation and is great as a pre-workout supplement.

Last is L-Carnitine-L-Tartrate which is the most common and the cheapest choice, although it is the fastest to be absorbed in the body. It also offers all the benefits of L-Carnitine along with improved physical strength and power output.

L-Carnitine can also come in capsules, quick-release gel capsules, tablets, powder and liquid form. Based on research, powdered products are more useful but are usually unflavored. This makes them unpleasant to take.

Although they elicit the same effects, liquid forms are flavored and much more comfortable to take orally. This is useful especially for people who find swallowing tablets or capsules difficult. However, this form is not for everyone.

Usually, the liquid types need to be taken through the eyes or drank from the bottle. The problem with this is you don’t have an exact measurement on how much you’re taking. Despite this, the liquid form is still the popular choice.

So, when choosing the form of L-Carnitine supplements, consider your convenience.

  • 3. Dosage

The minimum effective dose of Carnitine is 1000 mg or 1 gram daily. However, it is most beneficial for athletes if taken at doses between 2 to 3 grams per day.You should also pay close attention to the directions indicated on the bottle or container of the supplement.

Some products may have a fraction of the effective dose per serving but are instructed to be taken more than once a day. Others may come in full effective dosage per tablet or capsule and only need to be taken once.

  • 4. Manufacturer Reliability

When buying an L-Carnitine supplement, take note of the company that manufactures it. Choose those that are produced by a reliable company. These are most likely to be more effective and trustworthy.

Dependable companies could indicate that they are GMP (Good Manufacturing Practices) certified. This means that their facilities have been inspected by the government and that they have proper certifications and established reputations.

  • 5. Additional Minerals

Although it is preferable for most people to take pure L-Carnitine products, some may opt for those with added minerals. This can be of practical importance when you have specific needs.

Examples of these minerals include calcium and phosphorus which help with the absorption of nutrients or L-Carnitine itself. They also function for electrolyte balance which is vital for many bodily processes.

Furthermore, if you find yourself having to constantly adjust your daily intake of L-Carnitine, you should buy the BulkSupplements Pure L-Carnitine Powder instead. Since it is in powder form, it is easier to modify your consumption. You can also probably use it in shakes or whatnot.
