Yes I mean all the co-factors listed in Batches @xxxD3 regimen (D3,fish oil, magnesium, multi vitamin, super k) I think that's the basic co-factors but I always seem to leave one or two out. The detailed regimen can be found using the search bar at the top of the forum page. There are many underlying issues that can cause urticaria but CH and or vitamin intake is not one of them that I am aware of (sorry your dealing with that and roids) both seem very un-fun. Do you ride by chance? Motorcycles even extended horseback riding can cause them as well as straining on the porcelain throne (hemorrhoid's). I have a friend that participates in the Tevis Cup (long endurance ride) and he has to use a cushion on his saddle to help prevent a flair up. Any how Batches' D3 protocol is very highly recommended on her by many (myself included). The regimen takes time to build in your system so be willing to keep at it. Hopefully you have oxygen to hold you over until it can start working for you. Lastly, do consider reading the blue banner at the top of each forum page (New users please read here first). I am assuming that you already have by your "Advanced" status but ya never know. Hope this help!
