On his May 19th wedding day, Prince Harry was in possibly the best shape of his life — and he has his new wife, Meghan Markle, to thank for the inspiration.

According to the source, the couple teamed with Gabriela Peacock, a nutritional advisor to the royal family and founder of GP Nutrition. Harry, 33, is a fan of her Clean Me supplements for immune system support and healthier skin and nails.

And her efforts worked. “Harry has lost weight, started a healthier diet and even gave up smoking cigarettes,” a source says. “They both felt amazing leading up to the wedding. And he couldn’t have done it without her support.”
