Is NOW Foods a Good Supplement Brand?

Is NOW Foods third-party tested?

NOW describes extensive in-house testing and outside certifications, but these are not interchangeable. A laboratory tests samples; a facility certificate evaluates manufacturing practices; a product certification covers the named formula. Look for the evidence that answers your particular concern.

Independent facility assessment is meaningful. So is a transparent testing policy. Neither turns a supplement into a clinically proven treatment. Our USP versus NSF guide explains how to read the different marks.

There is also some independent product-testing evidence. ConsumerLab’s public NOW report card lists 45 selected products: 39 approved, 5 not approved and 1 with another status, as checked October 19, 2026. The product-level details require membership. This is not a random sample of the whole catalog or a pass rate for the bottle you are considering. ConsumerLab’s public summary.

A named extract also needs a product-specific check: our review of NOW KSM-66 Ashwagandha 600 mg distinguishes the root formula from other NOW extracts and addresses the important clinical cautions.

Where are NOW supplements made?

NOW is a US company founded in 1968. That does not mean every ingredient comes from the US. For example, the current magnesium glycinate tablet label says it is made and quality tested in the USA with globally sourced ingredients. Check the exact product’s label if origin matters to you; company location, manufacturing location and ingredient origin are different details. Company history; tablet label.

Why are NOW supplements often cheaper?

NOW attributes its pricing to purchasing ingredients at scale and maintaining its own testing facilities and staff. These are the manufacturer’s explanations, not an independent audit of its costs. A lower price alone does not show weaker quality; a higher price does not show better results. [1]

Compare the same active amount and bottle size. A low sticker price can still buy fewer servings. Include shipping, and distinguish a one-time price from a subscription or promotion.

The review of NOW Taurine 1000 mg, 100 capsules shows the per-1 g capsule calculation and keeps the low unit price separate from unproven human longevity claims.

Which NOW products are worth comparing?

These examples answer different shopping questions. Choose the ingredient for a reason first, then compare the exact formula rather than buying several products because the brand looks good.

Our review of NOW Methyl B-12 5000 mcg, 120 lozenges adds a practical version check: the current manufacturer lists 5-MTHF, while the seller’s older table still lists folic acid.

We also review Super Enzymes, Whole Psyllium Husks, Berberine HCl and NAC. Those are separate ingredient decisions, not additions everyone needs.

Another separate ingredient decision is NOW Inositol Powder 8 oz; the review checks the 730 mg label serving and why it should not be treated as an established PCOS regimen.

What should you check before buying a NOW supplement?

• The Supplement Facts line: identify the active amount per serving, not just the front-label number.
• The full ingredient list: check allergens, gelatin, sweeteners and ingredients you specifically avoid.
• The dose: a high-potency bottle is not necessarily a better everyday option.
• The seller: check the seller’s identity, return policy, seal and expiration on arrival.
• The proof: ask for the exact certification or lot report if that determines your choice.

For context before shopping, use our magnesium guide, omega-3 guide or probiotic guide. If you have kidney disease or take medicines, get appropriate advice before adding magnesium. [4]

Is NOW better than Solaray or Doctor’s Best?

There is no defensible whole-brand winner without naming a product and a requirement. For magnesium, compare tablets, capsule count, added ingredients and cost for the same elemental amount. For an athlete, an exact sport listing can matter more than the brand’s general reputation.

Use our five-product magnesium glycinate comparison alongside the Solaray review and Doctor’s Best review. None of these brand names guarantees better absorption or fewer side effects for every formula.
