This is a great graphic….but you should have included Oxytocin,,,,the LOVE hormone….let me know when you update this!!

Hi Todd, there’s a reason oxytocin is left out here; the three chemicals shown are those primarily involved in attraction. As I’m sure you’re probably already aware, oxytocin is more involved in attachment.

I do plan a more comprehensive post on the chemistry of love, which *will* include oxytocin. This was just a quick one for Valentine’s Day, and as it says, it just highlights “some of the many chemicals involved”. Unfortunately, I haven’t had the time this week to put together a more comprehensive graphic, but there’s always next year!
