Hi Linda,
Haven't taken the tabs, but have used apple cider vinegar with olive oil on my salads for years and put a teaspoonful in a glass of water and sip it for digestive purposes. It's also a great cleanser for vegetables and counter tops. (It used to be the way they cleaned ships and warded off infection prior to the cleanser industry!)
Am not trying to lose weight, but that's good information to know.
Best,
Carolyn
