Supplements for improving circulation??

[FlyingCoo]

Just wondered if anyone used or knew of anything that was worthwhile to use to improve circulation?
My boy has occasional puffy/lumpy legs and it is just one of his things depsite me having many heart attacks and calling the vets for umpteen times and getting scans/bloods done. I have lived with it for years and has as much turnout as possible,correct feeding & exercise etc so only wondered if there was something to boost circulation as he never complains about it but would be nice if there was something that eased it.I use mag boots when I can to help too.
Thanks

Horse chestnut is meant to help with circulation in humans - used for varicous veins.
Also maybe milk thistle to support the liver which also has an influence on the circulation.
