Urine changes with Vitex Berry

I have recently started taking Vitex Berry supplements to help with PMS and regulating my cycle.

it’s been about 2 weeks and so far so good other than my pee is SO dark. it started with a little greenish tint and now it almost has a brownish tint.

Has anyone experienced this because of the Vitex? I’m not positive if that’s what cause it but i’m hoping it’s nothing serious.
