BrainGain and FibroProtek contain even more luteolin.
About the light chains; IgG4 could elevate this level. Since this level is high in my case one time testing is not enough. I need to test it multiple times to see if it changes in time, if not, then the IgG4, which has a long half-life, could be responsible for elevation because it's broken down into light chains. Someone with POIS and without elevated immunoglobulins is a better candidate for testing light chains.
It's also strange I feel better outside at sub-zero temperatures, I mean immediately. I actually can feel a good muscle pain after riding a bicycle, it feels like there is a repair process going on after exercise outside which I normally don't feel. Higher temperatures surpresses this effect, it's like there is a competition between inflammation/destroying and repairing muscles. Or muscles tend to get more blood volume per sec due to vasoconstrictive effects from the cold. It's mostly noticable in the upper leg/quadriceps, low dose hydrogen peroxide did a similar thing to the muscles. I also tend to recover faster from POIS during sub zero temperatures, I need to dress properly and don't shiver because of the cold though. Plus less food reactions and the brain feels a bit lighter in a good way.
