Webber Naturals Vitamin B12 5000mcg Quick Dissolve, 60 Tablets
Cheap, effective correction for people who genuinely need it. The megadose exists because your body absorbs so little, not because more energy comes out the other end.
Best for: Vegans and vegetarians, adults over 50, metformin and acid-reducer users, and anyone whose bloodwork came back low. These are the groups where supplementation has actual evidence behind it.

Cheap, accurate and genuinely useful for fine glue and ink work, provided you accept that 30G will clog with anything thicker than water.
Best for: Hobbyists, model builders, electronics repairers, printer-ink refillers and crafters who need a hair-thin, controlled bead of thin liquid and want spares so they can throw a clogged tip away instead of fighting it.
