Whether you follow a plant-based diet, are over 50, or simply need a nutritional boost, this supplement can help you maintain optimal B12 levels.

Key Benefits of Vitamin B12

Vitamin B12 contributes to many aspects of your wellbeing. It supports normal energy-yielding metabolism, helping your body convert food into usable energy so you feel less tired. It also supports the normal functioning of your nervous system and maintains cognitive health. B12 is essential for normal red blood cell formation, which ensures oxygen is carried efficiently throughout your body. Additionally, it contributes to normal homocysteine metabolism, a factor in cardiovascular health. Including B12 in your daily routine gives your body the tools it needs to perform optimally.

Who Should Take a Vitamin B12 Supplement?

Certain individuals are more likely to benefit from a B12 supplement. Vegans and vegetarians often have low intakes because B12 is naturally found only in animal products. Older adults may have reduced stomach acid, impairing absorption from food. People with digestive conditions such as Crohn’s disease or coeliac disease, as well as those who have had weight loss surgery, may also struggle to get enough. Additionally, those taking acid-reducing medications or metformin might require extra B12. If you fall into any of these categories, a daily lozenge can help bridge the gap and support your overall health.

What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin your body depends on for several critical processes. It helps convert food into cellular energy, supports DNA and red blood cell production, and maintains the protective myelin sheath around your nerves. Without sufficient B12, you may experience fatigue, weakness, and cognitive difficulties. Most adults need about 2.4 mcg per day, but many factors can increase your requirement, such as age, diet, or digestive issues. That’s why a supplement like this 2000 mcg lozenge offers a reliable way to maintain your B12 status.

How to Choose the Best B12 Supplement

When selecting a B12 supplement, consider the form, dosage, and delivery method. Source Naturals uses cyanocobalamin, a stable and well-studied form that your body converts into active B12. With 2000 mcg per lozenge, this high potency ensures you receive a substantial amount — especially important for those with absorption challenges. Lozenges are an excellent choice because they dissolve in the mouth, allowing B12 to be absorbed directly through the oral mucosa, bypassing potential digestive issues. This sublingual-like delivery can be more effective for some individuals. This product is free from yeast, dairy, egg, gluten, soy, wheat, sugar, salt, preservatives, and artificial additives, making it suitable for many sensitive individuals. It is manufactured in the USA following Good Manufacturing Practises and meets Health Canada’s standards for natural health products.

How to Use Source Naturals Vitamin B12 Lozenges

Take one lozenge daily. For best results, allow it to dissolve completely in your mouth before swallowing. This method maximises absorption and is gentle on the stomach. You can take it at any time of day, with or without food. Consistency is key — regular use helps maintain steady B12 levels in your body.

Frequently Asked Questions

Can you take too much B12? Vitamin B12 is water-soluble, meaning excess amounts are typically excreted in urine. It has a very low potential for toxicity, even at high doses like 2000 mcg. However, always follow the recommended use and consult a healthcare professional if you have specific concerns.

Is this B12 vegan? The cyanocobalamin used in this product is synthetic and not animal-derived, so it is suitable for vegans and vegetarians. Some individuals may prefer methylcobalamin for specific health needs; this product uses the widely accepted cyanocobalamin form.

How long does one bottle last? With 100 lozenges per bottle and a serving size of one lozenge per day, each bottle provides a 100-day supply.
