Key Benefits of Vitamin B12

Discover Source Naturals Dibencozide — Vitamin B12 is essential for converting food into energy, supporting your nervous system, and maintaining healthy red blood cells. This vital nutrient contributes to normal energy-yielding metabolism, meaning it helps your body use energy from food. It also supports the normal function of the nervous system and contributes to the reduction of tiredness and fatigue. B12 is necessary for the normal formation of red blood cells, which carry oxygen to your tissues — making it especially relevant for athletes and those with active lifestyles. Additionally, B12 contributes to normal homocysteine metabolism and normal psychological function. These claims are authorised by the European Food Safety Authority (EFSA). This product is a food supplement and should not be used as a substitute for a varied diet and healthy lifestyle.

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 critical role in energy-yielding metabolism, red blood cell formation, and neurological function. It helps convert the food you eat into usable energy by supporting the metabolism of fats and proteins. B12 is also required for the synthesis of DNA and the maintenance of healthy nerve cells. Without adequate B12, your body cannot produce enough red blood cells, which can lead to fatigue, weakness, and cognitive difficulties. Since the human body cannot produce B12 on its own, it must be obtained through diet or supplementation — particularly for those following plant-based diets or with absorption issues.

What Makes Dibencozide (Adenosylcobalamin) Different?

Dibencozide is another name for adenosylcobalamin, one of the two biologically active coenzyme forms of vitamin B12. Unlike the more common cyanocobalamin (a synthetic form), adenosylcobalamin is ready for your body to use immediately. It works directly in the mitochondria — the powerhouses of your cells — to help metabolise branched-chain amino acids and produce ATP, the primary energy currency of the body. This makes dibencozide particularly attractive for athletes and anyone seeking to support energy production at the cellular level. By choosing a coenzymated form like adenosylcobalamin, you bypass multiple conversion steps, potentially enhancing bioavailability for those with methylation issues.

Who Should Consider a Vitamin B12 Supplement?

Certain groups are at higher risk of B12 deficiency and may benefit from supplementation. Vegans and vegetarians often lack dietary B12 because it is naturally found only in animal products. Older adults frequently experience reduced stomach acid production, which impairs B12 absorption from food. Individuals with gastrointestinal conditions such as Crohn’s disease, coeliac disease, or pernicious anaemia may also struggle to absorb B12 efficiently. Additionally, people who have undergone weight loss surgery or take medications that reduce stomach acid may need supplementary B12. Athletes and active individuals may seek B12 to support energy production and recovery during prolonged exertion.

How to Choose the Best B12 Supplement

When selecting a vitamin B12 supplement, consider the form, dosage, delivery method, and certifications. Coenzyme forms like methylcobalamin and adenosylcobalamin are often preferred because they are biologically active. Adenosylcobalamin is especially beneficial for mitochondrial energy support. Dosage typically ranges from 500 µg to 5,000 µg per serving — higher doses are common for deficiency correction. Lozenges or sublingual tablets can improve absorption by dissolving under the tongue, bypassing the digestive system. Look for products that are non-GMO, gluten-free, and manufactured in GMP-compliant facilities for quality assurance.

Recommended Dosage and How to Take B12

For general maintenance, many adults take between 500 and 1,000 µg of B12 daily. For those with deficiencies or higher needs, doses of 5,000 µg are common. This supplement suggests taking 1 lozenge daily between meals or 30 minutes before workouts. For best results, allow the lozenge to dissolve in your mouth before swallowing. This sublingual method may enhance absorption by allowing the vitamin to be absorbed directly through the oral mucosa. Always consult your health care provider before starting any new supplement regimen.
