I have gout and I drink apple cider vinegar daily even though I'm taking gout medications. The medications are not very effective for me on their own.
It can be tough to take apple cider vinegar, but it's not so bad when a tablespoon is added to a glass of warm water with honey. I take it on an empty stomach in the morning, it seems to work better. I buy apple cider vinegar with the mother, because this type is more beneficial.
My neighbor has gout too and he too tried apple cider vinegar. He said it didn't work for him though, so I'm not sure if this remedy works for everyone.
