Love has been a healing potion for Dina Lohan.

Famed mom Lohan — who’s had some widely publicized struggles of late — tells us she credits fiancé Jesse Nadler with getting her life back on track.

“Jesse is the sole catalyst for getting me in shape and [with] a healthy mind, body and soul,” she told us, adding, “My love for him is [like] nothing I have ever felt in my entire life.”

The pair — who’ve been engaged twice — went through a rough patch lately, but they’re hopeful they’ll make their relationship work this time.
