Brand Overview

NOW Foods is one of the largest supplement manufacturers in the US, founded in 1968. They operate NPA GMP-audited facilities and have built a strong reputation for delivering reliable quality at accessible prices. NOW does not chase premium positioning - they produce straightforward formulations at high volume and pass the savings on. Their products rarely earn top marks for quality certifications (most lack USP or NSF verification), but they also rarely disappoint. For budget-conscious buyers who want a brand with a decades-long track record, NOW Foods is the most reliable mid-tier option available.
