Hi. Happy 79th.
I don't know about interactions between your anti depressant and Lion's Mane mushroom, but info is available on high profile legit medical websites.
I suffered major cognitive deficits and exhaustion. I added *lab confirmed* Lions Mane supplements and I had measurable improvement. I only add only one new thing at a time. That fruiting body mushroom component ( as opposed to other less potent forms) had been a genuine therapeutic agent for me. We're all different. And not all products are legit sold under various labels. But I have nothing but good to say about it. I take "Real Mushrooms" brand via Amazon. 3rd party tested. I'm a Senior too. Had no negative effects for me.
