One of the questions we’re asked the most is some variation of, “Where should I buy supplements? Which brands can I trust?”

To help answer these questions, we put together a list of the supplement brands we trust (in alphabetical order).

Things change quickly online:  companies go out of business or are sold, and new ones are formed.  We’ll be updating this guide every 6 months, so that it’s always up to date.  Last updated:  September 29, 2016.
