    How much B12 do I need?

    Vitamin B12 plays a key role in energy, metabolism, mood, red blood cell production, and overall nervous system health.

    But the amount you need depends on your diet, age, lifestyle, and absorption ability.

    1. Everyday Use (0–500µg/day)

    If you eat a fairly balanced diet and don’t have absorption issues, the recommended daily intake is 2.4µg (RDI).

    Because B12 absorption is naturally low, many people use 10–500µg/day for daily energy, focus, and general wellness.

    Best for:


    • People with a mixed or omnivore diet

    • Anyone wanting a daily energy/mood boost

    • Younger adults with no known deficiencies

    2. Vegans, Vegetarians & Over 50s (500–1000µg/day)

    B12 is found almost entirely in animal products.

    Plant-based diets + age-related changes in stomach acid = higher chance of low B12 levels.

    Best for:


    • Vegans & vegetarians

    • Adults over 50

    • Anyone wanting extra support for energy, focus, and overall vitality

    3. Recovering From Low B12 (1000–3000µg/day)

    If a blood test shows low B12, short-term higher doses (1,000–3,000µg/day) are often recommended until levels improve.

    Once balanced, most people switch back to a maintenance dose (250–500µg/day).

    Best for:


    • Confirmed low B12

    • Fatigue, low mood, or other deficiency-related symptoms

    • Anyone following professional guidance

    4. Absorption Issues (3000–5000µg+/day)

    Some people struggle to absorb B12 from food or capsules due to digestive conditions, surgery, or genetics.

    These cases often require higher, supervised dosing.

    Best for:


    • People with known absorption challenges

    • Individuals after gastric bypass or with digestive conditions

    • Anyone advised by a health professional

    Why Our Liquid B-Complex Works Better

    📌 Sublingual = Better absorption

    Our liquid absorbs under the tongue, bypassing digestion — ideal for anyone who wants faster uptake or may not absorb capsules well.

    📌 Balanced B-Complex Formula

    Includes B1, B6, and B12 for:


    • Energy & metabolism

    • Mood & focus support

    • Healthy nervous system function

    • Overall daily vitality

    📌 Adjustable dosing

    Each serving contains 500µg of B12 — easy to scale up or down depending on your needs.

    How to Use


    1. Shake gently

    2. Place 1ml (one full pipette) under the tongue

    3. Hold for 30 seconds for maximum absorption

    4. Repeat servings if targeting a higher daily intake

    How do I take B12?

    Our B12 is sublingual, which means it's designed to be absorbed under the tongue for maximum effectiveness. Here's how to take it:

    For best absorption, squeeze the liquid directly under your tongue and hold it there for around 30–60 seconds before swallowing. This allows the B12 to enter your bloodstream more efficiently.

    Alternatively, if you prefer, you can still mix it into a drink or smoothie or take it straight from the pipette. Just note that this will reduce the absorption compared to sublingual use.

    Any time of day works – there’s no specific time you need to take B12 for it to be effective, so feel free to incorporate it into your routine whenever it suits you.

    What Customers Feel After 30 Days

    • “Way cheaper than the injections I was getting”

      I used to get B12 injections for neuropathy in my feet. They helped but omg the cost was insane. I switched to this liquid B complex and honestly the results feel similar. My tingling isn’t constant anymore and the burning sensation calmed down a lot.

      Jenny 73.

    • “Didn’t expect much but I legit feel a difference”

      I clicked from the TikTok ad thinking it was another overhyped product, but the info about the nerve sheath actually made sense. After a week, the pins and needles in my toes aren’t nearly as bad. Liquid is way easier to take too.

      Sophia 38

    • Sciatica had me moving like I was 70 at 34.

      Leg zaps, numb thigh, couldn’t sit through a movie. Felt old and broken. Tried this after seeing the ad. Within a couple weeks the shocks calmed way down and I can sit without pain. All I wanted was to feel normal again — this helped me get there.

      Liquid B12 works faster because it absorbs under your tongue instead of going through your stomach.

      Your body uses B12 to make energy, support your mood and focus, and keep your nerves healthy.

      Once it enters your bloodstream, it helps your cells turn food into fuel and supports the myelin sheath — the protective “insulation” around your nerves.

      That’s why proper B12 levels can help you feel more energized, clear-minded, and comfortable day-to-day.
