These patches work very well for me. Oral vitamins didn't seem to work for me but my labs got better after using Patch MD vitamins patches.
I have been using the patches for over 5 years now and my labs have been great. LOVE THEM as they work for me and I slap them on in the am and take them off in the PM and never give it a thought More...
I have low Vitamin D and when I found these patches I was a little apprehensive to try. However, since using them consistently for 6 mos my Vitamin D has improved. I will continue to use the patches!
