The read
Spring Valley Vitamin B12 2500 mcg: the formulation holds up. Lead: Vitamin B12 at 2500 mcg. B12 at 2500mcg is above optimal (1000mcg) and in the diminishing returns zone, but excess B12 is harmlessly excreted so this isn't a safety concern. Clinical dose on the primary, and the panel holds together.
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.
