This was the 16th annual event and per The Hollywood Reporter, Hilary became the dinner’s special honoree, “receiving the Environmental Working Group Changemakers Award in recognition for her role in helping pass California Senate Bill 646, which requires prenatal vitamin manufactures to test for and disclose levels of potentially harmful heavy metals in their products.”

In her statement, the Oscar winner said, “Receiving the EWG Changemaker Award is a profound honor, but the real victory is the progress we’ve made together with California Senate Bill 646. As a mother, I believe every parent deserves the peace of mind that comes with knowing the vitamins they take to support their pregnancy have been tested for the presence of heavy metals.

“Our health is our greatest asset, and I am proud to stand with EWG and HealthyBaby to ensure that no woman is left in the dark about what she is putting into her body. When we demand better standards, we aren’t just protecting ourselves, we are protecting the next generation,” she continued.
