I have been taking D3 for three or four years, and my frequent colds have also improved greatly. I bought 5000iu for my relatives to prevent the recurrence of cancer. The body's D is enough. Studies have shown that cancer can be reduced a lot. I hope it will help him.
Wonderful and highly effective vitamin! The doctor advised me, since we have few sunny days, starting in autumn. And the lack of vitamin D affects the mood, the entire skeletal system suffers. This product has been rigorously tested for years and has shown great results! I trust this manufacturer, as I have ordered products more than once. I am very happy with my choice! It actually works! I recommend to all! If my information was useful to you, please like it, I will be very grateful.
