L-carnitine, all the knowledge in one place!

L-Carnitine is an organic chemical compound, a vitamin-like substance first discovered and isolated in the early 20th century. L-carnitine can be delivered to the body through both endogenous synthesis and through food and supplements. Its best sources in the daily diet are red meat and milk and its derivatives.

1. It's in the works

L-carnitine is a compound with strong antioxidant properties, which may in some ways slow down the aging process, in particular by reducing the negative impact of excess free radicals. L-Carnitine has many different functions, although the most important one seems to be the active support and stimulation of β-oxidation of fatty acids.

2. Applications

L-carnitine has gained popularity mainly among people who want to regulate their body weight. All because of its ability to be used for fat reduction. It has undoubtedly also attracted interest among physically active people who consider it to be a supplement that can help increase fatigue resistance and strength and oxygen resistance, which in the long run translates to improved outcomes. However, older people can use L-Carnitine to improve motor and cognitive abilities.

3. Dosage and method of use

There is no single universal dose of L-carnitine per person that would guarantee the full spectrum of action described. However, pure L-Carnitine supplementation is most commonly considered in the range of 5002000 mg. This amount should be divided into several (i.e. 23) smaller portions taken during the day, which is usually also suggested by the manufacturers of the products available on the market. Higher doses of 3000 mg/day, which also appear to be completely safe, may be used e.g. by athletes who are ambitious amateurs.

4. Counter-indications

Based on current medical knowledge, it can be assumed that L-carnitine is completely safe and well tolerated by humans, hence there are no clear contraindications for its use.

5. Unwanted activity

There is a very low likelihood of side effects when taking the recommended L-carnitine doses, although some people may experience relatively harmless gastrointestinal disorders such as nausea or diarrhea while taking the supplement.

6. It's a performance

L-carnitine is present in products such as: meat (barley, beef, pork, horses, poultry); fish; dairy products; ?? mushrooms (oatmeal, baked goods) food of plant origin (mushrooms, carrots, avocados, soybeans).
