Have you heard/tried high doses of vitamin D3 for asthma? I haven't used my flovent in well over a month now. I am taking 6,000 IU of D3. Some in the homeopathic/natural medicine community use as much as 50,000 IU of D3 for many things, but the consensus is that asthma symptoms are improved overall. Mayo clinic is currently using high doses of D3 for prostate and breast cancer patients.
