A quick google search, says it has polyphenols in it. I already mix ACV with my water, for it’s hyper-tensive properties. But apparently red wine vinegar has polypenols that come from that red wine used to make it.
Assuming those polyphenols are actually beneficial for your health (not necessarily), you’d likely need to drink such a large volume that it would be impossible for this to be beneficial.
Don’t worry about antioxidants or other such things in my opinion. Eat a varied, whole food diet and you’ll be covered.
