Buyer’s Guide

Now that we’ve provided you with five top-quality L-carnitine supplement options. We will discuss some L-carnitine benefits.

We will also discuss other things to consider before or when taking the supplement.

As a well-informed consumer, you should be able to confidently decide whether or not this is the best type of supplement for your health needs.

What Is L-Carnitine?

Before you start taking a daily L-carnitine supplement, it’s crucial to know what it does and how it works.

L-carnitine is a naturally occurring type of amino acid. It can boost an individual’s energy levels by transporting fatty acids into the mitochondria (where they become energy).

High-protein foods, such as animal products like meat, fish, and dairy, are primary sources for L-carnitine. Vegans and vegetarians often rely on supplements to avoid a deficiency.

Individuals who have dialysis, liver disorders, use some medications, or have genetic disorders may be more prone to an L-carnitine deficiency.

L-Carnitine Benefits For Your Health

Many manufacturers target their L-carnitine supplements to people who want to lose weight.

They also target people who want to improve their athletic performance (endurance), and relieve muscle fatigue due to working out.

L-carnitine supplements may benefit all of the above.

It may also help people with severe deficiencies due to liver disease, improve heart health, and regulate blood sugar. And it may even prevent age-related memory issues.

Potential Side Effects

Like all supplements, there is always a potential risk of side effects. Although pure L-carnitine supplements are relatively safe, it’s important to talk with your doctor if you are pregnant or nursing. It’s also crucial to discuss your health history with your doctor before using the supplement. And to never give it to a child without consulting a pediatrician first.

Potential side effects include, but are not limited to nausea and vomiting, upset stomach, heartburn, loose stools, seizures, and giving urine, sweat, and breath a “fishy” smell.

If you experience any side effects that are worrisome or out of the ordinary. Make sure to consult your doctor immediately.

As with any supplement, you should talk with your doctor about any supplements or medications that you are taking. This is to see if it will interact with the L-carnitine supplement. Blood clotting and thyroid medications are known to have adverse interactions with the supplement.

Reading The Label

While the supplements that we reviewed and put on our “best” list are pure forms of L-carnitine, it’s essential that you know how to read a label. Make sure you understand all the dosing directions and the ingredient list. Avoid products that don’t have a clear list of ingredients or dosing information.

While most supplements are not regulated by the FDA, it’s better to purchase a product that is manufactured in a GMP-certified facility. If you have sensitivities to any specific ingredients, read the label carefully. If you are unsure, contact the manufacturer.

What’s The Best Amount To Take For Maximum L-Carnitine Benefits?

As you read the L-carnitine labels, you may notice that the recommended doses vary from one supplement to the next. Many health experts say that the most effective and safe dose is anywhere from 500 to 2,000 mg per day. Others recommend no more than 1,000 mg per day.

For the dose that’s ideal for you, it is best discussed with your health professional.

If you plan to take more than 500 mg a day, start out with a low dose and slowly work your way up. Moreover, this may help prevent some side effects.

Finally... Getting The Maximum L-Carnitine Benefits

L-carnitine supplements may provide numerous benefits to individuals depending on their health needs. For individuals who want to use the supplement as an aid for weight loss, a healthy diet and regular exercise routine may help reap the maximum benefits of the supplement.

It’s also important to consider that if you eat a well-balanced diet that is rich in animal-products, L-carnitine may not be the best supplement for your health goals. If you do decide to take the supplement, and you are not L-carnitine deficient, you should consider the lowest dose available.
