Leucine is an essential amino acid. It belongs to a special group of amino acids called branched-chain amino acids (BCAAs), which are needed to help maintain and repair muscle tissue. Leucine also helps prevent muscle proteins from breaking down during exercise.
While there is still some question as to whether leucine and other branched-chain amino acids improve exercise performance or enhance the effects of physical training, supplements may be beneficial under certain conditions. Some studies have shown that leucine and other BCAAs prevent muscle loss at high altitudes and may prolong physical endurance under extreme heat. People with liver and kidney failure may also benefit from leucine supplementation. In addition, a trial published in 1988 found that BCAA supplements help patients with Lou Gehrig's disease maintain muscle strength; other studies have refuted these findings, however.
The recommended daily dosage of leucine and other branched-chain amino acids is 25-65 mg four every 2.2 pounds of body weight. Most diets provide an adequate amount of BCAAs. Competitive athletes sometimes take larger amounts — up to five grams of leucine (and 11 grams of BCAAs overall) per day.
All protein-containing foods have some amount of leucine and other BCAAs. The best sources include red meat and dairy products such as eggs, milk and cheese. Whey protein and egg protein supplements are other good sources. Leucine is usually sold in conjunction with other amino acids.
Only individuals who are deficient in protein would become deficient in leucine. However, since most Western diets provide more than enough protein, leucine deficiency is extremely rare. High intake of leucine and other BCAAs could cause these substances to be converted into other amino acids (or to fat for storage). Individuals with kidney or liver disease should not consume large amounts of leucine or other BCAAs without first contacting a qualified health care practitioner. At the time of this writing, there are no known drug interactions with leucine. As always, make sure to consult with a licensed health care provider before taking leucine or any other dietary supplement or herbal remedy.

Chronic pain afflicts over 20% of the adult population. Sadly, most MDs have essentially no education in treating pain, beyond offering a few toxic medications. Then they tend to steer people with pain away from those health practitioners who are trained. This puts the acupuncture community on the front lines for addressing this epidemic.
When the body is going through a stressful event, the sympathetic system is activated. This activation will help the body with a life-threatening situation. If this state is activated for prolonged periods of time, it starts to consume energy. These traumatic events that generate stressors in the autonomic nervous system (ANS) will eventually become internalized.

One of the things that makes acupuncture so difficult to measure is that the medicine actually does contain some esoteric aspects. There have been numerous studies that demonstrate the neurochemical reasoning behind why acupuncture points stimulate the autonomic nervous system to enact change However, not all the benefits of TCM can easily be measured by randomized, controlled trials. But does that make them fundamentally and definitively untrue?
