Life Extension Vitamina B12 Metilcobalamina 5 mg, 60 comprimidos sublinguales

What is vitamin B12 and why is it important?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for multiple bodily functions. It plays a crucial role in red blood cell formation, nervous system maintenance, and energy production. Our body cannot produce it on its own, so it must be obtained through diet or supplements. People on vegetarian or vegan diets, those over 50, and those with absorption disorders are at higher risk of deficiency.

Key benefits of vitamin B12

Vitamin B12 contributes to several important functions supported by the European Food Safety Authority (EFSA):

• Contributes to the normal functioning of the nervous system.
• Contributes to normal psychological function.
• Contributes to the reduction of tiredness and fatigue.
• Contributes to normal energy metabolism.
• Contributes to normal red blood cell formation.
• Contributes to the normal functioning of the immune system.
• Contributes to normal homocysteine synthesis, thus supporting cardiovascular health.

This methylcobalamin supplement offers the active form of vitamin B12, ready to be used by the body without the need for liver conversion.

Different forms of vitamin B12: cyanocobalamin vs. methylcobalamin

Vitamin B12 comes in several forms. Cyanocobalamin is the most common and stable synthetic form, but it requires the body to convert it into the active forms: methylcobalamin and adenosylcobalamin. Methylcobalamin is the natural and active form that directly participates in processes such as neurotransmitter synthesis and cellular detoxification. By choosing methylcobalamin, the conversion step is avoided, which can be beneficial for people with certain genetic variants (e.g., MTHFR) or absorption problems.

Who needs vitamin B12 supplements?

Vitamin B12 supplementation can be especially beneficial for:

• Vegans and vegetarians: B12 is found primarily in animal products.
• Older adults: B12 absorption decreases with age due to reduced intrinsic factor.
• People with digestive disorders such as Crohn's disease, atrophic gastritis, or bariatric surgery.
• Those taking medications such as metformin or proton pump inhibitors, which can lower B12 levels.
• Anyone experiencing fatigue, lack of concentration, or mood swings related to low B12 levels.

What is the best form of vitamin B12?

The choice between cyanocobalamin and methylcobalamin depends on individual needs. Methylcobalamin is the active form and is often recommended for optimal nervous and cognitive support. In addition, sublingual or rapid-dissolving tablet presentations facilitate direct absorption into the bloodstream through the oral mucosa, bypassing digestive barriers. This format is ideal for those who have difficulty absorbing B12 from food or traditional tablets.

How to take this supplement?

Dissolve one sublingual tablet (5 mg) daily, preferably on an empty stomach in the morning. Place it under the tongue and let it dissolve completely before swallowing. The 5 mg (5000 mcg) dose is adequate to cover daily needs and compensate for possible deficiencies. Do not exceed the recommended dose.
