 Ultimate Nutrition’s L-Carnitine

Description

Ultimate Nutrition's L-Carnitine delivers maximum strength L-carnitine to burn fat, enhance energy and promote performance. L-carnitine is a vitamin-like compound produced in the body from the essential amino acids methionine and lysine. L-carnitine enhances cellular energy production by using fat as energy. It transports fatty acids into the cell's mitochondria (the cell's energy powerhouse). The mitochondria converts energy from food molecules (such as fats) into ATP energy for cell functions.

L-carnitine helps build muscle and improve resistance to muscle fatigue. Carnitine's increased use of fat as energy can preserve muscle glycogen (stored energy) and decrease muscle fatigue. Studies suggest that carnitine supplementation may enhance athletic performance, especially endurance activities.

Since the 1930s, studies have been conducted on L-carnitine suggesting that it supports heart health. L-carnitine may improve heart function by increasing the heart's output and energy supply, as well as promote cardiac performance. The U.S. Food and Drug Administration (FDA) has approved the use of L-carnitine, under the drug name Carnitor, for carnitine deficiency prevention and therapy.

Although L-carnitine is made in the body or can be found in animal products (especially red meats), it can be considered a conditionally essential nutrient if demand for it exceeds the body's ability to produce it. People who may have low levels of L-carnitine include vegans/vegetarians, breast-feeding women, premature infants, those on hemodialysis, and injury and burn victims. Other reasons for low levels of carnitine include a genetically based carnitine defect, complications of diabetes, kidney disease or cirrhosis, certain heart conditions and advancing age.


Pros

Ultimate Nutrition's L-Carnitine can be especially beneficial for athletes and those who workout on a regular basis. L-carnitine can enhance exercise performance, help replenish energy stores in muscle post workout and promote the body's fat burning effect. L-carnitine may also have promising effects for those with certain types of heart conditions, under a physician's supervision.

L-carnitine's numerous benefits include:

  • Maximizes fat burning for energy
  • Promotes physical performance
  • Supports heart health
  • Prevents deficiency if the body's demand for it exceeds production

Cons

Although side effects are uncommon, nausea, vomiting, diarrhea, body odor and stomach upset have been reported.

The "D" form of carnitine is toxic and has been banned in the United States. D-carnitine must not be taken as it can create an L-carnitine deficiency in muscle and interfere with L-carnitine and acetyl-l-carnitine function.

People with hypothyroidism, seizures and high triglyceride levels should not supplement with L-carnitine without consulting a physician.

Be aware that some drugs may interact with L-carnitine including:

  • Allopurinol
  • Anticonvulsants
  • AZT
  • Chemotherapy
  • Doxorubicin
  • Gabapentin
  • Isotrentinoin
  • Phenobarbitol
  • Valproic Acid
  • Zidovudine

Is it for you?

If you wish to enhance your exercise performance and replenish your muscle's energy stores, Ultimate Nutrition's L-Carnitine may be for you. If you're at risk for carnitine deficiency (as described above) or want to support your heart health, you may also benefit from L-Carnitine. However, people with hypothyroidism, seizures and high triglyceride levels should not supplement with L-carnitine without consulting a physician.


Dosage and Directions

Take 1 tablet two to three times daily between meals. Or take as directed by your qualified health care provider. If taking for performance enhancement, take 1 tablet prior to workout on an empty stomach. Keep away from heat, light and moisture. Store in a cool, dry place.
