    FAQs

    How much B12 do I need?

    Vitamin B12 is essential for energy, brain function, and red blood cell production—but how much should you take?

    It depends on your diet, age, and health status.

    Everyday Health (0–500µg/day)If you eat a balanced diet with some B12 sources and have no absorption issues, the recommended daily intake is 2.4µg (RDI).Since absorption varies, many take 10–500µg/day for general health and energy.

    Best for: Omnivores, those who eat some B12-fortified foods, and young adults with no absorption concerns.Vegans & Over 50s (500–1000µg/day)B12 is mostly found in animal products, making plant-based eaters more prone to deficiency. As we age, stomach acid levels drop, reducing B12 absorption.

    Best for: Vegans, vegetarians, and anyone over 50 who needs extra B12 support.B12 Deficiency Recovery (1000–3000µg/day)If a blood test confirms low B12, short-term high doses (1000–3000µg/day) are often recommended to restore levels quickly.Once levels stabilize, most people switch back to a maintenance dose (500µg or less per day).

    Best for: Those diagnosed with low B12, experiencing symptoms, or following a doctor’s advice.Medical Conditions & Megadosing (3000–5000µg+ per day)Those with medical conditions affecting B12 absorption (e.g., pernicious anemia, Crohn’s disease, gastric bypass) may require higher doses under medical supervision.

    Best for: Anyone with a diagnosed absorption issue—consult a healthcare professional.Monitoring Your B12 LevelsFor the most accurate advice, consult a health professional. A blood test is the best way to check your B12 levels.

    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.

    Why do I need to take B12?

    Why Not Just Get B12 from Food?

    While B12 is naturally found in animal products like meat, dairy, and eggs, there are several reasons why supplementation might still be necessary.

    Even if you consume animal products, some individuals have trouble absorbing B12 due to factors such as age, digestive issues, or certain health conditions. Additionally, modern farming practices have altered the way B12 is present in animal products, meaning you might not be getting as much as you think.

    For those on a plant-based diet, B12 is not available in plant foods, making supplementation essential. To ensure you're meeting your needs, B12 supplements provide an effective and reliable solution5.

    Contributes to Reducing Tiredness & Fatigue and Normal Immune function

    B12 contributes to reducing tiredness and fatigue, as well as a normal immune function. Without enough B12, you might feel drained and run down. Studies show that B12 helps the body produce red blood cells and supports immune function, helping you stay healthy and energised3.

    Contributes to Mental Clarity & Balanced Mood

    B12 plays a crucial role in maintaining normal brain function, contributing towards mental clarity. It also supports the production of serotonin, the 'feel-good' chemical, contributing to a balanced mood4.B12 isn’t just about avoiding deficiency; it’s about contributing to reducing tiredness and fatigue, a normal immune system and normal mental clarity.

(This resource explains that B12 absorption can be impaired by certain conditions, and supplementation is recommended for individuals who have difficulty absorbing B12 from food sources.)

    Do I need to take B12 if I already use Supergreens?

    If you are currently taking Supergreens then in most cases you would not need to take an additional B12 supplement. Supergreens contains a range of different vitamins and minerals, including B12, so with daily use you would have this nutrient covered. If you require a higher or more therapeutic serving of B12 then you can consider taking this supplement in addition to Supergreens. If you are in doubt about how much you should consume we recommend contacting your healthcare practitioner.

    How should B12 be stored?

    This can be stored in a cool dark place until opened and then once opened it is important that you then store it in a fridge and use within 3 months.

    Is our B12 suitable for children?

    Our B12 is designed with adults' nutritional needs in mind. We recommend speaking with a doctor or nutritionist about the product's suitability and dosages for your child’s needs.
