Isoleucine 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. Isoleucine also helps prevent muscle proteins from breaking down during exercise.
While there is still some question as to whether isoleucine 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 isoleucine 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 isoleucine 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 isoleucine 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 two grams of isoleucine (and 11 grams of BCAAs overall) per day.
All protein-containing foods have some amount of isoleucine 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. Isoleucine is usually sold in conjunction with other amino acids.
Only individuals who are deficient in protein would become deficient in isoleucine. However, since most Western diets provide more than enough protein, isoleucine deficiency is extremely rare. High intake of isoleucine 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 isoleucine or other BCAAs without first contacting a qualified health care practitioner.
At the time of this writing, there are no known drug interactions with isoleucine. As always, make sure to consult with a licensed health care provider before taking isoleucine or any other dietary supplement or herbal remedy.

Governor Gavin Newsom has retracted the proposed budget cuts to the Medi-Cal acupuncture program for low-income Californians for the 2024-2025 budget year. This decision marks a significant victory for health care providers and advocates who have long championed acupuncture as a vital component of comprehensive medical care.
There’s no doubt that many of your patients visit your practice because they are in pain. And there’s certainly no doubt that curcumin from turmeric (Curcuma longa) can be incredibly effective in stopping that pain, whether due to chronic conditions like arthritis or acute pain from intensive workouts. But your patients may also benefit from curcumin for other reasons.

Fair and appropriate wages in health care are typically based on economic evaluations. A simple literature review illuminates that acupuncture is missing economic evaluations; which implies you are either underpaid or overpaid. The complexity of services provided by most American acupuncturists, which they are trained and certified to provide, must be reimbursed fairly.
