Key Benefits

1. Supports Nervous System Health
B12 is essential for the production and maintenance of myelin — the protective sheath around nerve fibres that enables fast, accurate nerve signalling. Deficiency directly damages this sheath over time, causing the numbness, tingling, and neurological symptoms associated with B12 deficiency.

2. Supports Red Blood Cell Formation
B12 is required for DNA synthesis in red blood cell precursors. Without adequate B12, red blood cells become abnormally large and dysfunctional — a condition called megaloblastic anaemia that impairs oxygen delivery throughout the body.

3. Supports Energy Production
B12 plays a direct role in converting food into usable cellular energy. Low B12 is one of the more common and overlooked causes of persistent fatigue, particularly in vegetarians, older adults, and those on Metformin.

Product Description

Why B12 deficiency is more common than people expect
Vitamin B12 is found almost exclusively in animal products — meat, fish, eggs, and dairy. That makes it straightforward for most omnivores to obtain through diet, but a significant gap for vegans, vegetarians, and anyone who has meaningfully reduced their animal protein intake.

What surprises many people is how long deficiency can go undetected. The body stores 2–3mg of B12 primarily in the liver, meaning a shift to a plant-based diet can take two or more years before deficiency symptoms appear. And when they do appear, they are often vague enough to be dismissed — persistent fatigue, difficulty concentrating, low mood, numbness or tingling in the extremities.

In Singapore, the risk is well-documented. A local study of older Chinese vegetarian women found a 42% prevalence of B12 deficiency. A Singapore primary care study of patients with type 2 diabetes found 27.7% were B12 deficient, with vegetarianism associated with a 21-fold increased odds of deficiency in this group.

Why Methylcobalamin
Methylcobalamin is the naturally occurring, bioidentical form of B12 found directly in human tissues and food sources. It metabolically active forms your body uses — meaning it does not require conversion before performing its roles in nervous system maintenance and cellular metabolism.

On the question of absorption: the NIH Office of Dietary Supplements notes that no evidence shows absorption rates between supplement forms of B12 differ significantly. The case for Methylcobalamin is not about superior absorption — it is about form. It is the form your body uses directly, and the form that naturally occurs in food.

Who It Is For

  • Vegans and vegetarians. B12 is found almost exclusively in animal products; supplementation is essential for long-term B12 status on a plant-based diet
  • Adults 50 and above. Reduced stomach acid with age impairs B12 absorption from food even in regular meat-eaters
  • Adults on Metformin. Long-term Metformin use is a well-established risk factor for B12 depletion; anyone on long-term Metformin should discuss B12 monitoring with their doctor
  • Anyone experiencing symptoms that may indicate low B12 — fatigue, tingling extremities, poor concentration, low mood.
  • Vitamin B12 (as Methylcobalamin)

Function: The active form of vitamin B12, supporting energy production, red blood cell formation, and healthy nervous system function.

Supporting Ingredients: Corn Starch, Magnesium Stearate, Silicon Dioxide

Take 1 capsule daily, whenever it fits your routine. For best absorption, take on an empty stomach. Or take as directed by a healthcare professional. Store in a cool and dry place.

Caution: Individuals with medical conditions should consult a healthcare professional before using any dietary supplements.

Most supplements aren't what the label says

  • NUS tested 18 NMN products sold in Singapore. Over 80% were not what they claimed.

    In 2024, researchers at NUS Yong Loo Lin School of Medicine and Temasek Polytechnic bought 18 NMN supplements on the Singapore market and measured what was actually in them. More than 80% contained less NMN than the label claimed. Three contained no detectable NMN at all.

    What that means for you: in this category, price tells you nothing about whether the product is real. An independent lab result is the only thing that does.

  • US researchers tested 25 melatonin gummies sold for sleep. Nearly 9 in 10 were not what they claimed.

    In 2023, researchers from Harvard Medical School and the University of Mississippi bought 25 melatonin gummy products on the US market and measured what was actually in them. 22 of the 25 were labelled inaccurately, with melatonin ranging from 74% to 347% of the stated dose. Only 3 came within 10% of the label. One contained no melatonin at all, just CBD.

    What that means for you: the dose on the label is a promise, not a measurement. You could be taking a fraction of what you paid for, or more than three times it. An independent lab result is the only way to know.

What we test and how often

Microbial & heavy metals

Every single batch we manufacture is tested by Eurofins Singapore for microbial safety and heavy metals before it is released for sale.

Laboratory: Eurofins Singapore

Raw material purity

Every lot of raw material is tested before it enters production. Our NMN returns greater than 99.99% β-NMN content.

Laboratory: SGS

Finished product content verification

Eurofins measures the actual NMN content in the finished capsule and confirms it delivers the stated 500mg per serving. This is the test almost nobody in the category runs, because it is expensive and because it is where underdosed products get caught.

Laboratory: Eurofins Singapore

  • The usual chain

    Manufacturer, then brand owner, then distributor, then retailer, then you. Retailers typically take 40 to 50%. Distributors take another 20 to 30%. Every layer is priced into the bottle before it reaches you.

  • Here at Estalife

    We manufacture it and we sell it. There is no brand owner paying us a manufacturing fee and no retailer adding margin on top.

  • What we did not cut

    Same raw material grade, same NSF GMP certified facility, same Eurofins and SGS testing, same processes and machines used for the hospitals and global brands we manufacture for.

Singapore's largest NSF GMP-certified supplements factory

Our Ang Mo Kio facility manufactures for hospitals and global brands, and now for Estalife directly — no middlemen. You're welcome to see it for yourself.

Moringa 1200MG: B12 fills the gap that plant foods like moringa can't.

Frequently asked questions

No. B12 is water-soluble with no established upper tolerable intake level and no known toxicity at supplemental doses. The body excretes what it does not need. The higher dose exists to ensure meaningful passive absorption in people who may have reduced intrinsic factor production — which includes a significant proportion of adults over 50.

Yes, though it is worth noting the Vitamin B Complex already includes B12. If you are supplementing B12 specifically to address a deficiency or because you are in a higher-risk group, the standalone 500mcg Methylcobalamin is the more targeted option.

Metformin is one of the most common causes of B12 depletion in Singapore's diabetic population. If you are on long-term Metformin, it is worth having your B12 level checked. This product is appropriate for daily maintenance, but if you are already significantly deficient your doctor may recommend a higher therapeutic dose or injections initially.

For best absorption, taking on an empty stomach is recommended as stated on the label. Taking with food is also acceptable — B12 does not have the food interaction concerns that apply to fat-soluble vitamins or iron.

Yes. The capsule is a vegetable capsule and all ingredients are vegan.

Think you can trust supplement labels? Think again.

A supplement label tells you what a brand says is inside. It can’t tell you whether that’s true.

In many markets, including Singapore, supplements aren’t independently checked against their labels before they’re sold. That’s why, when scientists test supplements against their labels, they keep finding products with far less, far more, or none of what’s claimed.
