Kyle Juszczyk’s life changed when he started living mostly off the land.

The 49ers fullback spends most of his off days in his gardens — indoor and outdoor — at his and wife Kristin’s home in San Jose, Ca.

“It always kind of catches people by surprise,” Juszczyk told The Post of his passion for gardening, which was passed down from his mother when he was a young child. “I always make it a point to go into my garden on my off days and get my hands in the dirt and really just take a second to put the phones down, feel the earth, get involved.”

Juszczyk, 33, spoke with The Post on behalf of POM Wonderful pomegranate juice, which is a staple within his clean diet and a great source for potassium.

Soon, he’ll be planting his own pomegranate trees, as he and Kristin — a fashion designer, who’s created pieces for Taylor Swift, Simone Biles and more — are adding a small orchard to their plot of land.

The couple, who wed in 2019, have turned their joint health journey into a lifestyle.

“I think it really has made a big difference in my health and being able to play as long as I have,” the NFL veteran said since abandoning store-bought vegetables, among other things.

“I’m in year 12 in the NFL at one of the most physical positions on the field and I feel incredible. I feel like I’m 25 out there. A lot of that is because of what I put into my body, POM Juice has been incredible antioxidant for me. It’s just is one ingredient.”

Juszczyk, who earned his eighth Pro Bowl nod in 2023, explained his indoor hydroponic garden has been a game-changer for growing his root vegetables, such as carrots, peppers, garlic and potatoes, for the last eight years.
