    About Vitamin B12

    Vitamin B12 helps your body make red blood cells, maintain healthy nerves and turn food into energy. It is found mainly in animal foods, so vegans and vegetarians often need a supplement. Absorption also declines with age and with long-term use of some medications, such as acid reducers.

    This collection includes methylcobalamin, adenosylcobalamin, hydroxocobalamin, B12 liquids, lozenges and B12 with folate from practitioner brands such as Pure Encapsulations, Thorne, Klaire Labs, Xymogen, BioGenesis and NutriDyn.

    How to Choose a B12 Supplement

    • Methylcobalamin: An active form of B12 that many practitioners prefer. Found in most liquids and lozenges here.
    • Adenosylcobalamin and hydroxocobalamin: Other active and long-acting forms. Adenosyl/Hydroxy B12 by Pure Encapsulations combines both.
    • Lozenges and liquids: Absorb in the mouth, which is helpful for people who absorb B12 poorly from the gut. Active B12-Folate lozenges are our top seller.
    • B12 with folate: B12 and folate work together. Formulas with methylfolate cover both. See B complex for the full family.
    • High-dose tablets: 5,000 mcg options such as B12 Pro are for people who need larger amounts.

    B12 is water-soluble and very well tolerated. Take it in the morning or early afternoon, since some people find it energizing. If you are over 50, vegan or take acid-reducing medications, ask your practitioner about checking your B12 status.

    Frequently Asked Questions

    What is the best form of vitamin B12?

    Methylcobalamin is the most popular active form. Some practitioners recommend a combination of methyl and adenosyl B12. Cyanocobalamin is also effective and is the most studied form.

    Who needs a B12 supplement?

    Vegans, vegetarians, adults over 50 and people taking certain medications are most likely to benefit. Your practitioner can check your B12 status with a simple blood test.

    Can I take too much B12?

    B12 has no established upper limit because excess is excreted. Follow the label, and talk to your practitioner before taking very high doses long term.

    Should I take B12 alone or in a B complex?

    Either works. A B complex covers all eight B vitamins, while B12 alone lets you target higher amounts.
