Who Should Take a Vitamin B12 Supplement?

Not everyone gets enough vitamin B12 from food alone. Certain groups are at higher risk of suboptimal levels and may benefit from a good-quality supplement. These include:

  • Vegans and vegetarians – Because B12 is naturally found in animal products like meat, fish and dairy, those on plant-based diets often need a supplement.
  • Older adults – As we age, our ability to absorb B12 from food declines due to reduced stomach acid.
  • Individuals with digestive disorders – Conditions such as Crohn’s disease, coeliac disease or pernicious anaemia can impair B12 absorption.
  • People taking certain medications – Long-term uses of acid-reducing drugs (proton pump inhibitors) or metformin may lower B12 levels.
  • Anyone seeking an energy boost – B12 plays a role in energy metabolism, making it a popular choice for those with busy lifestyles.

Carlyle’s B12 supplement is suitable for a wide range of users thanks to its vegetarian, non-GM and gluten-free formula.

Key Benefits of Vitamin B12

Vitamin B12 contributes to several normal bodily functions, many of which are recognized as health claims by the European Food Safety Authority (EFSA). These include:

  • Normal energy metabolism – B12 helps convert food into usable energy, which is why many people take it to combat fatigue.
  • Normal nervous system function – B12 is involved in the production of myelin, a protective sheath around nerves, helping maintain healthy nerve function.
  • Normal red blood cell formation – Adequate B12 is necessary for the formation of healthy red blood cells, which carry oxygen around the body.
  • Normal homocysteine metabolism – B12 works with folate to regulate homocysteine levels, which is important for heart health.
  • Normal psychological function – Some research suggests B12 may help support memory and concentration, particularly in older adults.
  • Normal immune function – B12 also plays a role in supporting the immune system.

Each of these benefits contributes to your overall wellbeing, whilst individual results may vary.

How to Choose the Best B12 Supplement

Not all B12 supplements are created equal. Here are key factors to consider when selecting a product:

  • Form of B12 – The two most common forms are methylcobalamin (bioactive) and cyanocobalamin (synthetic). Both are effective, but methylcobalamin is often preferred for neurological support. Carlyle’s B12 is formulated with a highly bio-available form.
  • Dosage – Carlyle delivers 5000 mcg per tablet, a high-potency dose that helps ensure adequate intake, especially for those with absorption challenges.
  • Delivery method – Sublingual tablets dissolve under the tongue, allowing B12 to be absorbed directly into the bloodstream, bypassing the digestive system. This is ideal for individuals with poor absorption.
  • Quality and purity – Look for supplements that are third-party tested and free from unnecessary additives. Carlyle’s tablets are non-GM, gluten-free and contain no artificial flavours or preservatives.
  • Flavour – A pleasant taste can make daily supplementation easier. Carlyle’s natural berry flavour is both delicious and appealing.

Recommended Dosage and How to Take This Supplement

The UK Reference Nutrient Intake (RNI) for vitamin B12 is 1.5 mcg per day for adults. However, higher doses like 5000 mcg are often used to correct deficiencies or support specific needs. Carlyle’s 5000 mcg sublingual tablets provide a potent dose that can be taken daily or as directed by a health care professional.

To uses: Place one tablet under the tongue and allow it to dissolve completely. This typically takes about 30 seconds. Do not swallow the tablet whole. For best results, take on an empty stomach or as advised by your health care provider.

Because B12 is water-soluble, excess amounts are generally excreted in urine, making it safe even at high doses. However, it is always wise to consult your health care provider before starting any new supplement regimen, especially if you have underlying health conditions or are taking medications.

What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is an essential water-soluble vitamin that plays a vital role in numerous bodily functions. It is necessary for the production of red blood cells, normal neurological function and DNA synthesis. Vitamin B12 also helps convert the food you eat into usable energy, making it a key nutrient for overall vitality.

Unfortunately, many people do not get enough B12 from diet alone. This is especially true for those following plant-based diets, as B12 is naturally found in animal products such as meat, dairy and eggs. Supplementing with a high-quality B12 like Carlyle’s 5000 mcg sublingual tablets helps fill dietary gaps and supports your body’s needs.

Frequently Asked Questions

Is it possible to have too much vitamin B12?

Vitamin B12 is considered safe even at high doses. The body excretes what it doesn’t uses, so toxicity is extremely rare. However, it is best to follow recommended dosages and consult a health care professional if you have concerns.

Is this B12 suitable for vegans?

Yes, Carlyle’s B12 tablets are vegetarian and contain no animal-derived ingredients. They are an excellent choice for those following vegan or vegetarian diets.

How long does it take to feel the effects of B12 supplementation?

Some people notice improved energy levels within a few days to weeks. However, individual results depend on your baseline B12 levels and overall health.
