“Medical Medium” Anthony William, the New York Times bestselling author, started praising the virtues of celery juice decades ago. Now he has published a new book—Celery Juice: The Most Powerful Medicine of Our Time Healing Millions Worldwide—that explains how this humble liquid can help people shed weight, heal chronic health issues, gain energy and improve digestion.

When he first started sharing this message with audiences, he thought, “If something really works, it will stand the test of time.” Since then, it’s become clear that drinking celery juice to improve health is no passing fad. There’s a good reason for its popularity, William says: “We’ve never been as sick as we are in this modern age.”

Several ingredients give celery juice its healing properties, he says, including sodium cluster salts, digestive enzymes, plant hormones, a unique form of vitamin C and trace minerals. Drinking at least 16 ounces of plain, fresh celery juice every day on an empty stomach yield maximum health benefits, he says.

“Celery juice is sweeping the globe,” says actor Sylvester Stallone. “It’s impressive how Anthony has created this movement and restored superior health in countless people around the world.”

Gwyneth Paltrow, another famous admirer of William’s work, says, “While there is most definitely an element of otherworldly mystery to the work he does, much of what Anthony William shines a spotlight on—particularly around autoimmune disease—feels inherently right and true. What’s better is that the protocols he recommends are natural, accessible and easy to do.”
