What critics say
Summarised from video reviews across each brand’s line — what they consistently praise, where they push back, with the press tone beneath.?
Reviewers praise
- Family-owned and privately held for multiple generations, allowing quality decisions over profit-driven ones
- In-house testing laboratory since the late 1990s with batch verification and label accuracy checks
- Broad product lineup spanning supplements, essential oils, collagen, sports nutrition, and pantry goods under one roof
Reviewers push back
- Essential oil testing is in-house rather than third-party, which some reviewers consider a transparency gap
- Published test results for essential oils lack batch numbers and dates, making traceability difficult
- Certain supplements, such as GABA, produce inconsistent or undetectable effects in some users
NOW Foods is a long-established, family-owned supplement and natural products brand with credible quality controls and a wide lineup, but its essential oils draw skepticism over in-house testing transparency, and some individual products produce inconsistent results across users.
On NOW Foods: On essential oil quality, one reviewer sees the brand as comparable to other accessible natural-store brands and acceptable for casual use, while another flags the absence of third-party GC-MS verification as a meaningful red flagOn supplement efficacy, one reviewer reports clear positive results from the collagen powder, while another cannot detect any effect from the GABA product, suggesting outcomes vary by category and individual
