What natural supplements can I take with sertraline(zoloft) to reduce anxiety?

I feel like the sertraline majorly helps with keeping negative thoughts at bay, keeping me from getting depressed etc. But I still have a lot of anxiety..

I would rather not switch over or add another drug just yet, so I’m wondering if anyone knows anything natural I can take with the sertraline to help with this. Google isn’t helpful. Thanks in advance 😊
