THORNE Vitamin B12 – Methylcobalamin – 60 Capsules

Who Should Take a Vitamin B12 Supplement?

Certain groups face a higher risk of vitamin B12 insufficiency. Vegans and vegetarians often lack dietary B12 because it is primarily found in animal products. Older adults may produce less stomach acid, reducing B12 absorption from food. Individuals with digestive conditions such as Crohn’s disease, coeliac disease, or pernicious anemia – and those who have undergone weight loss surgery – may also benefit. Additionally, long-term use of metformin or proton pump inhibitors can deplete B12 levels. THORNE Vitamin B12 offers a reliable, high-quality option to help fill these gaps.

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 nerve function, red blood cell formation, and DNA synthesis. It also supports energy metabolism by helping convert food into usable energy. Unfortunately, many Canadians struggle to get enough B12 from diet alone – especially those following plant-based diets or with reduced absorption capacity. THORNE Vitamin B12 delivers 1 mg (1000 mcg) of methylcobalamin per capsule, the naturally occurring, bioactive form that your body can use immediately without needing to convert it from synthetic sources.

Key Health Benefits of Vitamin B12

Helps maintain healthy homocysteine levels – Vitamin B12, along with folate and vitamin B6, helps keep homocysteine levels already within a normal range. Balanced homocysteine contributes to heart health.

Helps in the normal functioning of the nervous system – As methylcobalamin, this B12 is directly available for myelin production, the protective sheath around nerves. Healthy myelin supports efficient nerve signaling.

Helps to form red blood cells – B12 is essential for proper red blood cell development. Adequate red blood cells help carry oxygen throughout the body.

Aids methylation – Methylation is a fundamental biochemical process affecting gene expression, detoxification, and neurotransmitter production. Methylcobalamin is a key cofactor in this pathway.

How to Select the Right B12 Supplement

Not all B12 supplements are created equal. Two common forms are cyanocobalamin and methylcobalamin. Cyanocobalamin is synthetic and must be converted in the liver to active forms. Methylcobalamin is already active, making it more efficient – especially for those with methylation issues or who prefer a bioactive form. Dosage matters: 1000 mcg (1 mg) is a standard maintenance dose for most individuals, while higher doses may be recommended for deficiency correction. Delivery form also affects absorption; while capsules are convenient, sublingual options bypass the stomach for direct absorption. THORNE uses methylcobalamin in a simple capsule, free from gluten, dairy, and soy, and third-party tested for purity and potency.

Dosage and Usage Guidelines

For adults, the typical dosage is one capsule daily with food, unless otherwise directed by a healthcare professional. Each THORNE capsule provides 1 mg (1000 mcg) of methylcobalamin, a level that supports sufficiency for most people. B12 is water-soluble, so excess is excreted; however, always follow the label and consult your practitioner if you have specific health concerns.

Frequently Asked Questions

Can you take too much B12? Vitamin B12 has a very low toxicity risk. The body excretes excess through urine. However, it is best to stick to recommended doses unless advised by a healthcare provider.

Is methylcobalamin better than cyanocobalamin? For many people, methylcobalamin is preferred because it is the active form, especially for supporting methylation and nerve health. It may be more beneficial for individuals with certain genetic variations in the MTHFR gene.

Can I take this on an empty stomach? While B12 can be taken with or without food, taking it with a meal may improve absorption if you have sensitive digestion.
