B-12 1000 mcg, 60 Comprimidos Sublinguales - Progressive Laboratories

What is vitamin B12 and why is it important?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for numerous bodily functions. Its main functions include the normal formation of red blood cells, the functioning of the nervous system, and DNA synthesis. In addition, B12 is key to transforming food into energy usable by cells.

This Progressive Laboratories supplement provides 1000 mcg of vitamin B12 per tablet, presented in a fast-dissolving sublingual format. It is formulated with cyanocobalamin, the most stable and studied form of vitamin B12, ideal for maintaining optimal levels in the body.

Key benefits of vitamin B12

Vitamin B12 has health claims approved by the European Food Safety Authority (EFSA). Scientifically backed benefits include:

• Normal energy metabolism: Vitamin B12 contributes to normal energy metabolism, helping to convert food into energy usable by the body.
• Reduction of tiredness and fatigue: It helps reduce the feeling of tiredness and fatigue, promoting daily performance.
• Normal functioning of the nervous system: It supports the maintenance of the nervous system under normal conditions.
• Normal red blood cell formation: It is necessary for the production of red blood cells, which transport oxygen to tissues.
• Normal immune system function: It helps the proper functioning of the body's defenses.
• Cell division process: It intervenes in cell renewal, essential for rapidly renewing tissues.

Each of these benefits has been evaluated and authorized by the EFSA, which guarantees that the claims are supported by solid scientific evidence.

What is the best form of vitamin B12?

There are two main forms of vitamin B12 in supplementation: cyanocobalamin and methylcobalamin. Cyanocobalamin is the most stable and economical form, and the body easily converts it into the active forms (methylcobalamin and adenosylcobalamin). Methylcobalamin is the natural active form, but it is less stable.

This product uses cyanocobalamin, which has proven effective in correcting deficiencies and maintaining adequate levels. The 1000 mcg dose ensures sufficient intake to cover daily needs, even in people with high requirements or absorption problems.

In addition, the sublingual tablet dissolves quickly under the tongue, allowing the vitamin to be absorbed directly through the oral mucosa, bypassing the digestive tract. This can be beneficial for people with gastrointestinal absorption difficulties, such as older adults or those who have undergone bariatric surgery.

Who needs vitamin B12 supplements?

Vitamin B12 is found naturally in animal-derived foods: meats, fish, eggs, and dairy products. Therefore, certain population groups are at greater risk of deficiency:

• Vegans and strict vegetarians: By not consuming animal products, it is essential to supplement with B12 to avoid deficiencies.
• Older adults: With age, the ability to absorb B12 from food decreases due to reduced gastric acidity.
• People with digestive disorders: Diseases such as Crohn's disease, celiac disease, or atrophic gastritis affect absorption.
• Individuals who have undergone gastrointestinal surgery: such as gastric bypass or intestinal resection.
• Pregnant and lactating women: Requirements increase during pregnancy and lactation, especially if the mother follows a vegan diet.

Even people without risk factors can benefit from supplementation, especially if they experience fatigue, lack of energy, or mild neurological symptoms. It is always advisable to perform a blood test to determine levels before starting any supplement.

How to take B12 1000 mcg correctly?

The recommended dose is one sublingual tablet daily, or as directed by a healthcare professional. Place the tablet under the tongue and allow it to dissolve completely, without chewing or swallowing. Hold it for approximately 30-60 seconds for optimal absorption.

It can be taken with or without food, at any time of the day. As it is a water-soluble vitamin, excess is excreted in urine, so the risk of toxicity is very low. However, the recommended dose should not be exceeded without medical supervision.

This supplement is suitable for vegans, does not contain gluten, lactose, or other common allergens. Store in a cool, dry place, out of reach of children.

Frequently asked questions

How much vitamin B12 do I need per day?

The reference intake for adults in the European Union is 2.5 mcg per day. However, supplements usually contain much higher doses (500-1000 mcg) because absorption is limited: only a small fraction is absorbed orally. Sublingual doses of 1000 mcg guarantee adequate bioavailability even in people with reduced absorption.

Does vitamin B12 help with tiredness?

Yes, vitamin B12 contributes to the reduction of tiredness and fatigue, according to the EFSA. If fatigue is related to low B12 levels, supplementation can help regain energy. However, if tiredness persists, a healthcare professional should be consulted.

Can I take B12 with other medications?

In general, vitamin B12 is safe and rarely interacts with medications. However, some drugs such as metformin, proton pump inhibitors, and anticonvulsants can reduce absorption. If you are taking any treatment, consult your doctor before starting supplementation.

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.
