What Form of B12 Is Best? Methylcobalamin vs. Cyanocobalamin
Discover Member Mark Vitamin — When choosing a B12 supplement, you will encounter two common forms: cyanocobalamin and methylcobalamin. Cyanocobalamin is a synthetic form that is stable and inexpensive, but it must be converted by the body into active forms (methylcobalamin and adenosylcobalamin). For some individuals, this conversion may be inefficient, especially those with genetic variations or compromised liver function.
Methylcobalamin, on the other hand, is a naturally occurring, bioactive form of B12. It is already in the active form that your body can uses directly, without conversion. This makes methylcobalamin a preferred choice for supporting neurological health and energy metabolism. Member's Mark Vitamin B12 uses methylcobalamin, ensuring you get a form that is readily available for your body to utilise.
Additionally, these tablets are quick-dissolve, meaning they dissolve rapidly under the tongue. This sublingual delivery allows B12 to be absorbed directly into the bloodstream, bypassing the digestive system—an advantage for those with absorption issues. The delicious natural cherry flavour makes them pleasant to take daily.
Who Should Take a Vitamin B12 Supplement?
Certain groups are at higher risk for B12 deficiency and may benefit from supplementation. These include:
-
Vegans and vegetarians: B12 is naturally found in animal products such as meat, dairy, and eggs. Those following plant-based diets may not get enough from food alone.
-
Older adults: As we age, stomach acid production decreases, which can reduce the absorption of B12 from food.
-
Individuals with digestive disorders: Conditions like Crohn's disease, coeliac disease, or atrophic gastritis can impair B12 absorption.
-
People who have had gastrointestinal surgery: Surgeries that remove parts of the stomach or small intestine can affect B12 absorption.
-
Those taking certain medications: Long-term uses of acid-reducing drugs (proton pump inhibitors) or metformin for diabetes may lower B12 levels.
-
Individuals with pernicious anaemia: This autoimmune condition affects the body's ability to absorb B12 from food, often requiring supplementation.
If you belong to any of these groups, a high-quality B12 supplement like Member's Mark methylcobalamin quick dissolve tablets can help maintain optimal levels.
Key Benefits of Vitamin B12
Vitamin B12 contributes to many aspects of health. Here are some of its key benefits, supported by scientific research and EFSA-approved health claims:
-
Contributes to normal energy-yielding metabolism: B12 helps your body convert carbohydrates into glucose, which is used for energy. This is why adequate B12 levels are associated with reduced tiredness and fatigue.*
-
Contributes to normal function of the nervous system: B12 is essential for the maintenance of the myelin sheath, the protective covering around nerves. This helps ensure proper nerve signal transmission and may support cognitive function.*
-
Contributes to normal red blood cell formation: B12 is necessary for the production of healthy red blood cells. Adequate levels help prevent megaloblastic anaemia, which can cause fatigue and weakness.*
-
Contributes to normal homocysteine metabolism: B12 works with folate to regulate homocysteine levels. Elevated homocysteine is a risk factor for heart disease, so maintaining healthy B12 levels may support cardiovascular health.*

Recommended Dosage and How to Take B12
For general maintenance, a daily dose of 500 to 1000 mcg is often sufficient. For individuals with deficiency or absorption issues, higher doses up to 5000 mcg may be recommended by a health care professional. Always consult your doctor before starting a new supplement regimen, especially if you have underlying health conditions.
To uses the Member's Mark Vitamin B12 tablets, place one quick-dissolve tablet under your tongue and allow it to dissolve completely. This typically takes 30–60 seconds. Do not swallow the tablet whole. For best results, take it on an empty stomach, whilst it can be taken with food if preferred. Consistent daily uses helps maintain steady B12 levels.
Frequently Asked Questions
Can you take too much B12? Vitamin B12 is water-soluble, meaning excess amounts are excreted in urine. High doses are generally considered safe, but extremely high intake is rarely needed. Stick to recommended dosages.
Is methylcobalamin better than cyanocobalamin? For many people, methylcobalamin is preferred because it is the active form. It may be especially beneficial for those with MTHFR gene mutations or neurological concerns.
How long does it take to feel effects? Some users report increased energy within a few days, but individual results vary. Consistent uses over several weeks is recommended to assess benefits.
Are these tablets vegetarian/vegan? While not explicitly stated, methylcobalamin is often derived from fermentation, making it suitable for vegetarians and vegans. Check the label for confirmation.
