Effective for whooping cough and asthma! I tried various inhalers but found them ineffective. After reading about vitamin D, I started this supplement and noticed a difference within two days; my whooping cough significantly improved. I haven't caught a cold in three years since taking it. I appreciate the doctor's article and am grateful for this NOW supplement, which is hard to find in Japan, and to iHerb.

I experienced whooping cough asthma, and my doctor suggested vitamin D. After one month of use, I contracted the flu but haven't had asthma since; it feels cured. I trust this remedy and have continued taking NOW vitamin D, along with natto for a large amount of vitamin K.
