21st Century Vitamina B12 1000 mcg Comprimidos de Liberación Sostenida (330 Comprimidos)

What is Vitamin B12 and why is it important?

Discover 21St Century B-12 — Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for multiple body functions. It contributes to the normal formation of red blood cells, the functioning of the nervous system, and energy metabolism. In addition, it helps reduce tiredness and fatigue, making it a key nutrient for those seeking to maintain their daily vitality.

Our body does not produce vitamin B12 on its own, so we must obtain it through food or supplements. Natural sources include meats, fish, eggs, and dairy products, but people on vegetarian or vegan diets, as well as those with absorption problems, can particularly benefit from a supplement.

Key benefits of Vitamin B12

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

• Normal energy metabolism: Helps convert food into usable energy, which can lead to increased vitality.
• Reduction of tiredness and fatigue: Adequate B12 levels can help combat the feeling of exhaustion.
• Normal functioning of the nervous system: Maintains neuron health and promotes the transmission of nerve impulses.
• Normal formation of red blood cells: Essential for preventing certain types of anemia.
• Normal function of the immune system: Contributes to the body's defenses.

In addition, vitamin B12 participates in the cell division process, which is fundamental for tissue renewal.

Extended release: what does it mean and why choose it?

These 21st Century tablets feature an extended-release system. This means that vitamin B12 is released gradually throughout the day, rather than all at once. Why is this beneficial? B12 is a water-soluble vitamin that is quickly eliminated through urine if taken in high doses all at once. With extended release, more stable levels are maintained in the blood, optimizing its absorption and utilization.

Each tablet provides 1000 mcg of vitamin B12, a high dose that far exceeds the recommended daily needs. This presentation is ideal for people with high requirements or absorption difficulties.

Who can benefit from this supplement?

Vitamin B12 supplementation can be especially useful for:

• Vegans and vegetarians: Since they do not consume animal products, it is difficult to obtain enough B12 from diet alone.
• Elderly people: With age, the ability to absorb B12 from food decreases.
• People with digestive disorders: Such as Crohn's disease, celiac disease, or atrophic gastritis, which affect absorption.
• Those taking medication: Certain drugs, such as metformin or proton pump inhibitors, can reduce B12 levels.
• People with fatigue or lack of energy: B12 can help improve physical and mental performance.

If you are not sure if you need a supplement, consult a healthcare professional to assess your levels.

How to take these vitamin B12 tablets?

The recommended dose for adults is one tablet daily, preferably with a meal to facilitate absorption. Do not chew or crush the tablet; swallow it whole for the extended-release system to work properly. Each package contains 110 tablets, and this pack includes 3 packages, providing a total of 330 tablets, enough for almost a year's supply.

It is important not to exceed the recommended daily dose. Keep the product out of reach of children and store it in a cool, dry place.

Frequently Asked Questions (FAQ)

How much vitamin B12 do I need daily?

The reference intake for adults in the EU is 2.5 mcg per day. However, higher doses (such as 1000 mcg) are common in supplements, as the body only absorbs a small fraction. Extended release helps maximize absorption.

Does vitamin B12 make you gain weight?

No, vitamin B12 has no calories and does not contribute to weight gain. On the contrary, by improving energy metabolism, it can help maintain a healthy weight.

Can I take this supplement if I am pregnant or breastfeeding?

If you are pregnant or breastfeeding, consult your doctor before taking any supplement. B12 needs may increase during pregnancy, but the dose should be supervised.

Is this product suitable for vegans?

The vitamin B12 in this supplement is of synthetic origin (cyanocobalamin), making it suitable for vegans. However, check the label to confirm the absence of animal-derived ingredients.

Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended dose. Keep out of reach of children. This product is not intended to diagnose, treat, cure, or prevent any disease.
