Who Should Consider a Vitamin B12 Supplement?

Many people in Canada may not get enough vitamin B12 from diet alone. Vegans and vegetarians are at particular risk since B12 is found naturally only in animal foods. Older adults often have reduced stomach acid, which can affect absorption from food. Conditions like Crohn’s disease or coeliac disease, or surgeries such as gastric bypass, can also impair B12 uptake. Additionally, certain medications including metformin and proton pump inhibitors may interfere with B12 levels. If you fall into one of these categories, a supplement like NOW Foods B-12 2000 mcg lozenges can help maintain adequate levels. Always consult your healthcare provider to determine your individual needs.

What Is Vitamin B12 and Why Is It Important?

Vitamin B12, or cobalamin, is a water-soluble vitamin that plays essential roles in your body. It supports the nervous system by helping maintain the myelin sheath around nerves, and it is necessary for converting carbohydrates, fats, and proteins into energy. B12 also contributes to DNA synthesis and red blood cell formation, which are vital for overall health and vitality. Since your body cannot produce B12, you must obtain it from food or supplements. NOW Foods B-12 lozenges provide a potent dose in a convenient, great-tasting form that dissolves under the tongue.

Key Benefits of Vitamin B12

Vitamin B12 offers several well-established benefits. It supports normal energy metabolism by acting as a cofactor in cellular energy production — not as a stimulant, but as a necessary component. Nervous system health is another key area, as B12 helps maintain nerve cell function and supports neurological wellbeing. Adequate B12 levels are also associated with healthy red blood cell formation, ensuring proper oxygen transport throughout your body. Some research indicates B12 may help maintain cardiovascular health by regulating homocysteine levels. These benefits underline the importance of maintaining sufficient B12 for overall wellness.

How to Choose the Best B12 Supplement

The form of B12 in a supplement matters for absorption and activity. NOW Foods B-12 lozenges feature a triple-form blend: cyanocobalamin (a stable, well-studied form), methylcobalamin (a bioactive coenzyme that your body can use directly), and dibencozide (also known as adenosylcobalamin, another active coenzyme important for mitochondrial energy production). This combination provides comprehensive support. The lozenge delivery method allows for sublingual absorption, which may be beneficial for those with digestive issues. Look for certifications such as vegan, kosher, and gluten-free to ensure purity. NOW Foods products are GMP Quality Assured and third-party tested for potency and stability.

How Much B12 Should You Take?

The recommended dietary allowance (RDA) for B12 in Canada is 2.4 mcg per day for most adults, but many individuals benefit from higher doses to correct deficiencies or support specific health goals. Each NOW Foods B-12 lozenge provides 2,000 mcg — a high-potency option for those with increased needs. For best results, place one lozenge under your tongue and allow it to dissolve, ideally on an empty stomach. Consistent daily use helps maintain steady B12 levels. As with any supplement, it is wise to consult your healthcare provider before starting a new regimen, particularly if you have a medical condition or take medications.

Frequently Asked Questions

Can you take too much B12?

Vitamin B12 is water-soluble, so excess amounts are usually excreted in urine. Toxicity is rare, and doses up to 5,000 mcg are generally considered safe. However, it is best to follow the recommended dosage on the label and consult a healthcare practitioner if you have concerns.

Is sublingual B12 better than tablets?

Sublingual lozenges allow B12 to be absorbed directly into the bloodstream through the mucous membranes under the tongue, which may be particularly helpful for individuals with absorption issues in the digestive tract. Both forms can be effective, but lozenges offer a convenient and potentially more absorbable option.
