That's interesting. I take Vitamin B6, but not for EPS, even though I have some EPS (RLS and Akathisia). I take B6 as part of a preventative plan for calcium oxalate kidney stones, which I've had twice over the last 3 years. It certainly isn't helping my EPS, but I only take about 200 mg of B6 per day, which seems like a very low dose. Knock on wood it's helping to keep the kidney stones at bay so far (together with some other changes I've had to make to my diet etc etc).

What is the dose of B6 for EPS? I am certain my EPS comes from years (decades) of SSRI and/or SNRI use, specifically Sertraline, which has a strong correlation with TD and other EPS conditions. I've recently started Lithium which has exacerbated my RLS.

Anyhow, I'm so glad the B6 is helping your EPS!
