Tyrosine - a good fat burner?

Posted on February 24, 2012 at 1:00 PM
Tyrosine
 
Overview:Tyrosine is a nonessential amino acid the body makes from another amino acid called phenylalanine. It is a building block for several important brain chemicals called neurotransmitters, including epinephrine, norepinephrine, and dopamine. Neurotransmitters help nerve cells communicate and influence mood. Tyrosine also helps produce melanin, the pigment responsible for hair and skin color. It helps in the function of organs responsible for making and regulating hormones, including the adrenal, thyroid, and pituitary glands. It is involved in the structure of almost every protein in the body.It's rare to be deficient in tyrosine. Low levels have been associated with low blood pressure, low body temperature, and an underactive thyroid. This does not mean, however, that taking tyrosine supplements will help any of these conditions.Phenylketonuria (PKU)This serious condition occurs in people whose bodies can't use the amino acid phenylalanine. It can lead to brain damage, including mental retardation. People with PKU must avoid any phenylalanine in their diets. Because tyrosine is made from phenylalanine, people with PKU can be deficient in tyrosine. Tyrosine is used in protein supplements for people with PKU, but most doctors don't recommend more tyrosine supplements. If you have PKU, your doctor will determine if you need more tyrosine and how much.StressTyrosine is involved in the production of the stress hormones epinephrine and norepinephrine. Some researchers believe that, under stress, the body isn't able to make enough tyrosine from phenylalanine. Some animal and human studies suggest that tyrosine supplements may help improve memory and performance under psychological stress, but more research is needed.Sleep deprivationOne study suggests that taking tyrosine may help you be more alert after sleep deprivation, but more research is needed.OtherSome athletes claim that tyrosine helps their performance. However, there is no proof that this claim is true or safe.Because tyrosine helps the body produce the mood-influencing chemical dopamine, and because people who are depressed often have low levels of tyrosine, researchers thought that tyrosine might help treat depression. However, studies have found that it has no effect.Dietary Sources:Tyrosine is found in soy products, chicken, turkey, fish, peanuts, almonds, avocados, bananas, milk, cheese, yogurt, cottage cheese, lima beans, pumpkin seeds, and sesame seeds.Available Forms:Tyrosine is also available as a dietary supplement, in capsule or tablet form. How to Take It:Take tyrosine supplements at least 30 minutes before meals, divided into 3 daily doses. Taking vitamins B6, B9 (folate), and copper along with tyrosine helps the body convert tyrosine into important brain chemicals.PediatricDon't give tyrosine supplements to a child without first asking your doctor.AdultDoses vary. Talk to your nutritionist or doctor about what dose is right for you. To treat symptoms of sleep deprivation, one study used 150 mg per kilogram of body weight per day.Precautions:Because of the potential for side effects and interactions with medications, you should take dietary supplements only under the supervision of a knowledgeable health care provider.People who have migraine headaches should avoid tyrosine, as it can trigger migraine headaches and stomach upset.People with hyperthyroidism or Graves disease should avoid tyrosine supplements because tyrosine may increase levels of thyroid hormone.Possible Interactions:If you are being treated with any of the following medications, you should not use tyrosine supplements without first talking to your health care provider.Monoamine Oxidase Inhibitors (MAOIs) -- Tyrosine may cause a severe increase in blood pressure in people taking antidepressant medications known as MAOIs. This rapid increase in blood pressure, also called "hypertensive crisis,” can lead to a heart attack or stroke. People taking MAOIs should avoid foods and supplements containing tyrosine. MAOIs include:
  • Isocarboxazid (Marplan)
  • Phenelzine (Nardil)
  • Tranylcypromine (Parnate)
  • Selegiline
Thyroid hormone -- Tyrosine is a precursor to thyroid hormone, so it might raise levels too high when taken with synthetic thyroid hormones.Levodopa (L-dopa) -- Tyrosine should not be taken at the same time as levodopa, a medication used to treat Parkinson's disease. Levodopa may interfere with the absorption of tyrosine.Alternative Names:L-tyrosine

I've heard many times in many places that you shouldn't live and die simply by the scale and that you should instead plot your daily weight on an average curve that smoothes out the daily fluctuations in weight.

Green tea contains flavanoids called catechins, which are believed to boost metabolism, inhibit fat absorption and reduce appetite. Green tea is also very alkalizing and a great substitution for acidic morning coffee.

Really, Tyrosine has more importance for burning excessive fat. As, it helps to produce melanin, the pigment responsible for hair and skin color. I am really impressed to get this informative blog as well. Thanks
