Checks out. — Legitimate

"Methylcobalamin supports nerve function and energy"
PubMed trials confirm B12 reduces neuropathy symptoms — but only in people with confirmed low B12 levels.
PubMed: Methylcobalamin clinical trials (knowledge base) -
"Active B12 form — no conversion needed"
Methylcobalamin is genuinely the bioactive form. Cyanocobalamin must be converted; methylcobalamin skips that step.

"Supports energy metabolism"
Only true if you are B12 deficient. Normal B12 levels mean extra B12 is excreted, not used for energy.

Consumer advice
Get a blood test first. B12 supplementation has clear, proven benefits for deficient individuals — vegans, vegetarians, older adults, and people on metformin are the most likely to need it. If you're deficient, methylcobalamin is a solid choice over cyanocobalamin. The liquid capsule format is a nice touch for absorption, but sublingual lozenges (which are cheaper) work just as well clinically. Shop around — comparable methylcobalamin products from Jarrow, Solgar, or even store brands cost significantly less. Don't pay a premium just for the Sports Research branding.
