I use 2 tablespoon 1 or 2 x day. I use the cheap walmart Great Value brand. Make sure you mix it in a 4 oz beverage of your choice, for 2 reasons: it taste like shit and it is bad for the enamel on your teeth(I wish I would have known that about 2 years ago).
Bragg's apple cider vinegar is great for health and longevity. There are myriad of benefits from consuming it. I take about six tablespoons a day. It must be raw and unfiltered to get the health boosting benefits.
Mix one to three TBLs with 12 ounces pure water and sip with a straw to get it past your teeth then rinse mouth with water.
I eat two tablespoons at dinner (one on salad one afterwards). I think this helps me break down the proteins in the meal and absorb the nutrients from my veggies much better. It also goes to work on my Pre-bed shake (which is entirely whole foods).
Who knows? They say vinegar and cinnamon are both suppose to help with blood sugar. I got nothing noticeable from either. The studies are so damn hard to interpret. There are a thousand things involved. Placebo alone. Juice works, beyond that who knows...
I'm a very scientific person- I want studies, proof, but sometimes simple is best- kinda like how after all these years of training, I think real food is better than protein shakes, even though on paper a protein shake is just as good if not better.
But something about ACV is different- it even helps my acid-reflux (as well as Zantec, at least)- hard to believe drinking an acidic potion would help that.
