NOW Foods Folic Acid 800 mcg + B-12 Review

Name: NOW Foods Folic Acid 800 mcg + B-12
Brand: NOW Foods
Availability: InStock

8/10SAC Product Score™

NOW's folic acid tablet clears the prenatal folate target with room to spare — 800 mcg of folic acid, the same NTD-proven form as our top pick, plus 25 mcg of B-12 to support homocysteine metabolism. At roughly $8 for 250 tablets it is the cheapest way here to exceed the 400 mcg minimum. It loses a hair to Nature Made only because it carries GMP self-attestation rather than an independent USP seal, but the underlying substance and evidence are identical. If you want margin above the minimum dose and a token of B-12, this is the value play.

▸ THE SCORE

How we built the SAC Product Score™ — 8/10

NTD-Prevention Evidence30%9/10

Uses folic acid, the exact form validated in the MRC and Czeizel trials and recommended by the USPSTF.

Form & Bioavailability20%8/10

Standard synthetic folic acid, well-absorbed; the 25 mcg B-12 supports the same one-carbon metabolism pathway.

Dose Appropriateness20%7.5/10

800 mcg is at the top of the 400–800 mcg DFE prenatal range — fine and well within safe limits, though more than the 400 mcg minimum most need.

Third-Party Testing20%6.5/10

GMP Quality Assured and Non-GMO, but self-attested; no independent USP or NSF seal like the top pick.

Value10%9/10

Roughly $0.03 per tablet — the lowest cost-per-dose on the entire list.

▸ TRUTH CHECK

Marketing claims vs. reality

Verified

“800 mcg folic acid provides NTD protection”

800 mcg sits within the USPSTF-recommended 400–800 mcg folic acid range (PMID 28097362); the Cochrane review (PMID 26662928) confirms folic acid's protective effect across this dose window.

Partial

“Adding B-12 improves homocysteine metabolism”

Folate and B-12 jointly lower homocysteine, but a 25 mcg B-12 dose is modest and the clinical benefit of homocysteine-lowering for pregnancy outcomes is not firmly established.

▸ THE DEEP DIVE

What our test actually found

01800 mcg is safe but not necessarily better

Doubling the dose to 800 mcg stays well under the 1,000 mcg tolerable upper intake for folic acid and gives a comfortable margin, but there is no evidence 800 mcg prevents more NTDs than 400 mcg for the average woman.

02B-12 pairing is sensible, not transformative

Including B-12 addresses the second nutrient in the homocysteine pathway and can help vegetarians, but 25 mcg is a supportive touch rather than a therapeutic dose.

▸ THE TRADE-OFFS

Pros & cons, no sugar-coating

Pros

Same trial-proven folic acid form as the #1 pick
Lowest cost per dose on the list (~$0.03/tablet)
Higher 800 mcg dose gives margin above the minimum
Includes B-12 to support homocysteine metabolism
250-count bottle lasts over eight months

Cons

Only self-attested GMP testing, no independent USP/NSF seal
800 mcg is more than most women actually need

▸ THE BOTTOM LINE

The value winner for proven folate

If cost is the deciding factor and you still want the evidence-based form, this is the pick. You get the same folic acid used in the NTD trials, a generous dose, and B-12, for the least money. The only reason it sits at #2 is the absence of an independent testing seal — a real but modest gap versus Nature Made.
