Hi lifelong!

I'm weaning myself off spiro, too- it gives me horrible dry eye, even at low doses.

I don't think the brand matters as long as you're getting standardized extract. Others have mentioned that GNC is good. For me, I use Nature's Bounty. FYI, you can get headaches on SP, so try taking it with a meal. For me, I wait about 15 minutes after finishing a meal to take it and I seem to be warding off the headaches.

Check out Green Gables Big Hormonal post on acne- you'll get better results if you combine plant extracts rather than taking only SP by itself.

Good luck!
