SFI Health Active B12 - Suplemento de folato con metilcobalamina y metilfolato - Comprimidos sublinguales, 60 unidades

What makes this B12 supplement different?

Discover Klaire Labs Health — Not all forms of vitamin B12 and folate are created equal. This supplement uses methylcobalamin and methylfolate (Metafolin®), the biologically active forms that your body can use immediately. Unlike cyanocobalamin or folic acid, these active forms do not require liver conversion, making them ideal for people with absorption problems or genetic variants such as MTHFR. Presented in a convenient sublingual lozenge, this product offers fast and effective absorption through the mucous membranes of the mouth.

Key benefits of vitamin B12 and folate

Vitamin B12 and folate (folic acid in its active form) are essential nutrients that play vital roles in the body. According to the European Food Safety Authority (EFSA), these are some of their scientifically backed benefits:

• Vitamin B12 contributes to normal energy metabolism, helping to convert food into usable energy.
• Vitamin B12 contributes to the reduction of tiredness and fatigue, which is essential for those looking to maintain high energy levels throughout the day.
• Vitamin B12 and folate contribute to the normal functioning of the nervous system, supporting the transmission of nerve signals and neurological health.
• Folate contributes to normal psychological function, including mood and cognition.
• Vitamin B12 contributes to the normal formation of red blood cells, which is essential for oxygen transport in the body.
• Both nutrients contribute to the normal functioning of the immune system, helping to maintain the body's defenses.

These benefits make the combination of B12 and folate a comprehensive support for daily vitality, mental performance, and overall well-being.

Active forms: methylcobalamin and methylfolate

Methylcobalamin is the natural form of vitamin B12 found in the body. Unlike synthetic cyanocobalamin, methylcobalamin is ready to participate in key biochemical reactions, such as neurotransmitter synthesis and homocysteine metabolism. For its part, methylfolate (as Metafolin®) is the active form of folic acid, capable of crossing the blood-brain barrier and participating directly in the production of neurotransmitters such as serotonin and dopamine. This active combination is especially beneficial for people with polymorphisms in the MTHFR gene, which hinder the conversion of synthetic forms.

By choosing active forms, the body obtains nutrients without the need for additional metabolic steps, which can lead to greater efficiency and availability for the tissues that need them.

Who is this supplement ideal for?

This product is formulated for a wide variety of people who want to optimize their B12 and folate levels:

• Vegans and vegetarians: B12 is found mainly in animal-derived foods, so supplements are essential in plant-based diets.
• Older adults: the ability to absorb B12 from food decreases with age, making sublingual supplements especially useful.
• Individuals with absorption problems: conditions such as atrophic gastritis, Crohn's disease, or prolonged use of antacid medications can reduce B12 absorption.
• Those seeking support for energy, mood, and cognitive function: B12 and folate are cofactors in neurotransmitter production and energy metabolism.
• People with MTHFR genetic variants: who directly benefit from the active forms of folate and B12.

How to take sublingual lozenges?

The sublingual lozenge presentation is designed for optimal absorption. Simply place a lozenge under the tongue and let it dissolve completely. This allows nutrients to pass directly into the bloodstream through the capillaries of the oral mucosa, bypassing the digestive tract and potential losses due to incomplete absorption. It is an excellent option for those who have difficulty swallowing capsules or tablets.

The recommended dose according to product directions (check the label for specific information) is generally one lozenge per day, or as advised by a healthcare professional. Do not exceed the recommended daily dose.
