Vitamin B12 2500 mcg
Walmart's house brand B12 at rock-bottom prices. But cyanocobalamin needs conversion that some people can't do well. A $5 jar of methylcobalamin B12 from Jarrow is a small upgrade that actually matters.
5.5/10
DECENTWalmart's house brand B12. Cyanocobalamin form needs your body to convert it (and some people can't). Methylcobalamin is worth the small upgrade.

What We Like
- Incredibly cheap. Pennies per serving.
- Available at every Walmart.
- 2500 mcg is an adequate B12 dose.
Watch Out For
- Cyanocobalamin is the cheapest, least bioactive B12 form.
- No complementary B-vitamins for synergy.
- 120 tablets for $5 sounds good until you realize the quality matches the price.
