Swanson Vitamin B12 (Cyanocobalamin) 500 mcg, 100 Capsules

Who Needs a Vitamin B12 Supplement?

Vitamin B12 deficiency is surprisingly common, especially amongst those following a vegan or vegetarian diet, older adults with reduced stomach acid, and individuals with digestive conditions such as Crohn's or coeliac disease. If you take medications like metformin or proton pump inhibitors, your B12 levels may also be affected. Swanson Vitamin B12 provides 500 mcg of cyanocobalamin per capsule – a well-absorbed form to help maintain adequate levels and support your body's daily needs.

What Is Vitamin B12 and Why Is It Important?

Vitamin B12, also known as cobalamin, is an essential water-soluble vitamin that plays a key role in energy-yielding metabolism, red blood cell formation, and the normal function of the nervous system. It helps convert food into usable energy and is necessary for the maintenance of myelin, the protective sheath around nerves. Since the body cannot produce B12, it must be obtained from diet or supplements.

Key Benefits of Vitamin B12

• Energy metabolism: B12 contributes to normal energy-yielding metabolism, helping you feel energised throughout the day.
• Red blood cell formation: Working alongside folate, B12 is essential for normal red blood cell formation, supporting oxygen transport.
• Normal homocysteine metabolism: B12 helps maintain normal homocysteine levels, which is important for cardiovascular wellness.
• Nervous system support: B12 contributes to the normal function of the nervous system and normal psychological function.

Frequently Asked Questions

Is cyanocobalamin the same as methylcobalamin? No. Cyanocobalamin is a synthetic form containing a trace amount of cyanide, which is safe and effectively converted into active B12 in the body. Methylcobalamin is a bioactive form, but cyanocobalamin is just as effective for most people.

Can you take too much B12? Vitamin B12 is water-soluble, so excess is excreted in urine. It is generally considered safe even at high doses, but it is best to stick to the recommended serving size unless advised otherwise by a health care professional.

Does B12 give you instant energy? No. B12 supports the metabolic processes that produce energy, but it is not a stimulant. Regular supplementation helps maintain steady energy levels over time.
