Who Should Take a Vitamin B12 Supplement?

Are you concerned about maintaining adequate vitamin B12 levels? Many Canadians, particularly those following vegan or vegetarian diets, may not get enough B12 from food alone. Older adults and individuals with digestive conditions such as Crohn's disease or coeliac disease often face absorption challenges. Those taking medications like metformin or proton pump inhibitors may also benefit. Even if your diet includes animal products, a high-quality supplement like NOW Foods B-12 lozenges can help ensure you meet your daily needs for overall health and vitality.

What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is an essential water-soluble vitamin that your body cannot produce on its own. It is vital for DNA synthesis, red blood cell formation, and proper nerve function. B12 also helps metabolise fats and proteins into usable energy. Because deficiencies can lead to fatigue, neurological issues, and anemia, a reliable supplement like NOW Foods B-12 2000 mcg lozenges can help maintain optimal levels, especially for those with dietary restrictions or absorption difficulties.

How to Choose the Best B12 Supplement

Not all B12 supplements offer the same benefits. The form of B12 matters: cyanocobalamin is a common synthetic form, but NOW Foods B-12 contains three distinct bioactive forms, including methylcobalamin (readily used by the nervous system) and dibencozide (adenosylcobalamin), which supports mitochondrial energy production. The lozenge format allows sublingual absorption, bypassing the digestive tract for those with absorption issues. Plus, it's vegan-friendly, making it suitable for plant-based lifestyles.

Recommended Dosage and How to Take B12

Each lozenge delivers 2000 mcg of vitamin B12—a high-potency dose ideal for quickly correcting deficiencies or maintaining healthy levels. For best results, place a lozenge under the tongue and allow it to dissolve slowly, enabling direct absorption into the bloodstream. Take one lozenge daily, or as directed by your healthcare professional. Since B12 is water-soluble, excess amounts are generally excreted, and toxicity is rare. However, always consult a healthcare practitioner before starting any new supplement.
