ConsumerLab.com tests supplements and Swanson is basically always great.
As a rule, we get Swanson, NOW Foods, or Jarrow Formulas supplements, as the most trustworthy and tested. Get them the cheapest you can find, which may be on subscription from Amazon.
I used to shop at Swanson all the time and liked it. I just ended up simplifying things by sticking with iherb.com and sometimes fullscript.com (which is way cheaper than alot of sites). I do like Swanson products though so I’ll go that route. thanks for the tips.
