taking vitamin D and K supplement has helped decrease stutter

taking vitamin D and K supplement has helped decrease stutter hi everyone! I’m a college aged person who has stuttered for as long as I can remember, almost exclusively anxiety related (I think), because it only really exists when meeting new people or being in unfamiliar situations. Anyways, just wanted to share that I have been taking a vitamin D and K supplement (5,000IU every 2-3 days), and it has drastically improved my stutter. I think in some ways it potentially just decreased my anxiety/increased my confidence, but wanted to share in case it could help someone else. :)
