boosting immune function in endurance athletes
this is very interesting, supps to help with immune function for endurance athletes as well as other hard training athletes. worth a look

Athletes become increasingly susceptible to infection with intense training that results in immune suppression. The immune state was investigated after administering cystine/theanine (CT), which has been reported to have an immune reinforcement effect, to athletes before training involving a prolonged period of intense exercise. Fifteen long-distance runners were each allocated to the CT or placebo group, and the test food was ingested for 10 d prior to the start of training. Clinical examinations were performed before and after the training. The results indicate a significant increase in the high-sensitivity C-reactive protein (hs-CRP) and neutrophil count in the blood, as well as a decreasing tendency for lymphocytes in the placebo group, but not the CT group. These observations suggest that the ingestion of CT contributed to suppressing the change in inflammatory response, prevented a decrease in the immune function, and prevented infection and reduced symptoms when infected associated with continuous intense exercise.
I am one of these people with constant sinus infections with too much training. Good to know.
Very interesting information.
liftsiron is a fictional character and should be taken as such.
this has nothing to do with theanine. It is because cysteine increases intracellular GSH.

VOMITTING PSYCHO BABBLE CONTINOUSLY
Thought I'd throw this in too, since vitamin d is getting studied so heavily these days. I recall reading an article that said more interest was triggered when a psychiatrist at a mental hospital reasoned that his patients needed vitamin d supplements since they didn't get outside much. Later, they had a flu outbreak at the hospital and the only patients that really weathered the outbreak were those that were taking vitamin d supplements. I'm becoming convinced that it is the most important supplement to take to help prevent a host of health problems. Deficiencies are becoming extremely common these days. It seems like at least 1,000 iu per day is often necessary to get one up to proper levels.
Last year, I was surprised to see my blood test results, which indicated that I was well below the normal range; I live in the south and spend a lot of time outside. I started taking 1,000 iu per day and it got me to the low normal range, and have since increased to 2,000 iu per day. I believe it's generally well tolerated up to about 8,000 iu per day.
interesting, do you consume much diary produce? if its been low for a long time it might be worth getting a bone scan done, unless you lift weights
I eat fermented dairy, such as yogurt, but not milk, which I can't tolerate. I also drink almond milk, which is fortified with vitamin d, but I think some people probably just don't absorb it as well as others, and then even worse as we age.
Anyway, I'm going to post the link to the life extension article as soon as it gets posted on their site. As a member of their group, I sometimes get blood tests done by them and they were including the vitamin d test for free. They have a very strong opinion on vitamin d, citing studies that demonstrate that people with the highest levels of vitamin d are healthier in every regard - less cancer, less heart attacks, less inflammatory diseases, less flu, etc. They believe that around 80 to 90% of the general population has low levels of vitamin d, and that people should be trying to achieve high levels for better health.
