In general the best you can do is buy from companies that engage in Good Manufacturing Practices (GMP).
Here's a link.
I generally like NOW.
I also buy from Vitacost and Swanson and Jarrow, which were on the list in past years. Your mileage may vary.
Thank you!
Good to know. Thanks!
Even if they don’t say “made in China” 95% of the raw materials are made in China. Someone who worked in supplement manufacturing told me.
My rule of thumb is to never buy vitamins brands that are sold at Walmart or Target. They are packed with fillers and synthetics and most likely made in China. Find a good health food store or vitamin store (not GNC) An indication of a good vitamin shop is they usually have what I call a “vitamin sommelier” to help you find and select vitamins. Ask them questions. If they don’t know, they’ll look it up for you. Places I buy are Sprouts Market, Natural Grocers, Whole Foods, or find your local boutique “granola” shop if you’re lucky enough to have one near you. Some brands I know for certain made in USA are Green Pastures, Garden of Life, Nordic Naturals, Puritan’s Pride. Otherwise would have to double check brands (you need to check not just manufacturing location, but also where they source ingredients) before listing them here. I’ve been a huge fan of Jarrow for years, but just recently received an email from their corporate headquarters (they responded to my email asking why they had stopped manufacture of NAC Sustain) and the answer was effectually, “It was easier to fold than to fight the FDA” so I will be rethinking my relationship with them.
Most of mine come from Puritans Pride. You can buy in bulk at a big discount if you want to.
