Supplements for Receding Gums

I read that I might get some help with receding gums by taking some vitamin D3 supplements. I started taking 2000 iu of vitamin D3 once per day and within 2 weeks I noticed my gums getting noticeably worse. I stopped taking the vitamin D3 and within another 2 weeks I noticed my gums getting a bit better. I don't know if I was taking too much vitamin D3 or if the particular brand of supplement was bad for me but my gums did not appreciate it. Has anyone else had this reaction?
