It also comes in ginger, lemon and honey, apple and cinnamon and more flavours. Meanwhile, Bragg's also sells Organic Raw Apple Cider Vinegar which can be added to salads and veggies or even applied to the skin.

Victoria Beckham, meanwhile, consumes two tablespoons of the raw version every morning. "Be brave! Two tbsp first thing on an empty tummy! x" Victoria captioned a photo.
Katy has been using apple cider vinegar since her childhood, with her mum encouraging her to eat and drink healthily. She told Prevention: "My mother made me drink it every day, but now it’s a staple for me."

Her mum even became close to Patricia Bragg, and both Katy and Orlando are now co-owners of the company – the pair are even said to have both had apple cider vinegar-infused water with them when they went on their first date!
Speaking of her health, the new mum continued: "I’ve had a lot of opportunity in my life and I know how fortunate I am, but when I don’t have my health, nothing else matters.
"If I can’t get on the stage and do it, I disappoint so many people. I’ve lost my magical power if I can’t get onstage."
