Source Naturals Vitamin B-12, 2000 mcg – 50 Lozenges

What is vitamin B12 and why is it important?

Vitamin B12, also known as cobalamin, is an essential nutrient that the body needs for numerous vital functions. It contributes to the normal formation of red blood cells, the functioning of the nervous system, and energy metabolism. In addition, it plays a key role in DNA synthesis and the formation of the myelin sheath that protects nerves.

As a water-soluble vitamin, the body does not store it in large quantities, so it is necessary to obtain it regularly through food or supplements. The main dietary sources are animal products, which means that vegetarians and vegans are at a higher risk of deficiency.

Key benefits of vitamin B12

Vitamin B12 offers multiple benefits supported by the European Food Safety Authority (EFSA):

• Energy metabolism: Contributes to normal energy metabolism, helping to convert food into usable energy.
• Reduction of tiredness: Helps to reduce tiredness and fatigue, improving daily vitality.
• Nervous system: Contributes to the normal functioning of the nervous system, maintaining neuron health.
• Red blood cell formation: It is necessary for the normal formation of red blood cells, which promotes oxygen transport.
• Immune system: Contributes to the normal functioning of the immune system.
• Cell division: Plays a role in the cell division process.

These benefits make vitamin B12 a fundamental nutrient for people with low levels, such as the elderly, vegans, or those with absorption problems.

Different forms of vitamin B12: cyanocobalamin vs methylcobalamin

Two forms of vitamin B12 are mainly found on the market: cyanocobalamin and methylcobalamin. Cyanocobalamin is the most common and stable form, used in most supplements due to its low cost and long shelf life. Once in the body, it is converted into the active forms (methylcobalamin and adenosylcobalamin).

On the other hand, methylcobalamin is an active form that does not require conversion, so some consider it more bioavailable. However, both are effective in correcting deficiencies. The product we present contains cyanocobalamin, a widely studied and effective form.

Who needs vitamin B12 supplements?

Certain population groups have a higher risk of vitamin B12 deficiency:

• Vegans and vegetarians: By not consuming animal products, it is difficult to get enough B12 from diet alone.
• Elderly people: B12 absorption decreases with age due to the reduction of intrinsic factor.
• People with digestive disorders: Diseases such as atrophic gastritis, Crohn's, or celiac disease can affect absorption.
• Alcohol consumers: Alcohol can interfere with B12 absorption.
• Pregnant and lactating women: Needs increase during pregnancy and lactation.

If you experience symptoms such as persistent fatigue, weakness, memory problems, or paleness, it could be indicative of low B12 levels. A blood test can confirm this.

How to choose the best vitamin B12 supplement?

When choosing a vitamin B12 supplement, consider the following aspects:

• Form: Chewable tablets (lozenges) or sublingual sprays can improve absorption, especially in people with digestive problems.
• Dosage: 2000 mcg is a high dose, suitable for correcting deficiencies or maintaining optimal levels in people with high needs.
