These show that there is no overall increased risk of cancer from treatment with radioactive iodine. The small dose of radioactivity used means that radioactive iodine treatment is in no way like the radiation exposure following uncontrolled nuclear fallout which can cause thyroid cancer.
BCAAs reduce muscle soreness after intense exercise. BCAAs aid in post-workout recovery. by Jeff S. Volek, Ph.D., R.D. The branched-chain amino acids (BCAAs) leucine, isoleucine and valine have an important role in several aspects of recovery and may well be the most important of all the amino acids for athletes.
What it'll do for you: Branched-chain amino acids are often used to treat Lou Gehrig's disease, brain conditions due to liver disease, elderly and cancer patients and people who are confined to bed rest. Some perfectly healthy people use BCAAs to prevent fatigue and improve concentration. But the most relevant to you, perhaps, is the common practice of taking branched-chain amino acids to improve exercise performance and reduce muscle breakdown.
