    Vitamin B12 – why are deficiencies so common?

    Vitamin B12 deficiencies are among the most common micronutrient deficiencies. A plant-based diet may cause them, as may low gastric acid levels, impaired secretion of intrinsic factor (IF), and long-term use of certain medications such as metformin or proton pump inhibitors. An additional factor is stimulants – especially coffee and tea – which may affect nutrient bioavailability. For this reason, vitamin B12 supplementation is often an important element of a modern nutritional strategy.

    Expert Opinion

    "Vitamin B12 is one of those nutrients whose deficiency may remain unnoticed for a long time. Meanwhile, it is responsible for many key processes – from the functioning of the nervous system, through energy metabolism, to the production of red blood cells. In clinical practice, we very often encounter people who require conscious, long-term supplementation of this vitamin, especially with plant-based diets and absorption disorders."

    Vitamin B12 (hydroxocobalamin)

    Vitamin B12 is a water-soluble vitamin from the B group that naturally occurs only in products of animal origin. For this reason, its adequate intake is an important element of a nutritional strategy for people following plant-based or elimination diets, or diets with limited diversity of animal-derived products. In the human body, vitamin B12 acts as a coenzyme in several metabolic reactions, and its presence is essential for the proper course of many physiological processes.

    Hydroxocobalamin is one of the biologically active forms of vitamin B12, often chosen in supplementation due to its good tolerance and chemical stability. Unlike popular synthetic forms such as cyanocobalamin, hydroxocobalamin is a naturally occurring form of vitamin B12 and is widely used in long-term supplementation. This form can be used by the body flexibly both in metabolic processes and as a source for further conversion into other active forms of vitamin B12.

    Vitamin B12 participates in normal energy metabolism, helps reduce tiredness and fatigue, and supports normal psychological function. It also plays an important role in the functioning of the nervous system, including processes related to nerve conduction and maintaining cognitive performance. Additionally, it participates in red blood cell production and helps maintain normal homocysteine metabolism, which is important for the body’s metabolic balance.

    The use of hydroxocobalamin in liquid form allows precise dosing and easy adjustment to individual needs. The liquid form with a dropper makes it easier to incorporate the supplement into a daily routine, especially for people who prefer flexible dosing or have difficulty swallowing capsules. Thanks to this, vitamin B12 supplementation can be carried out in an organised, convenient way and in line with the principles of a conscious approach to nutrition and supplementation.

    Summary:

    BestB12 is a dietary supplement based on a single, well-thought-out active substance – vitamin B12 in the form of hydroxocobalamin. The liquid form, high per-serving content, and clean composition make it a convenient component of daily supplementation for people who care about diet quality and a conscious approach to micronutrition.

Additionally, each batch is tested for the presence of gluten and lactose to ensure safe use, even for people with the most sensitive digestive systems.
    • 4. Can the BestB12 product be used during pregnancy?

      The vast majority of BestLab supplements are safe to use during pregnancy, except for InsuBest and BestBody products. Supplementation during this special time can support the mothers health and the childs development; however, for your safety, we always recommend consulting a doctor before starting any dietary supplement.

    • 5. Can BestB12 be used while breastfeeding?

      Similarly to pregnancy, most BestLab supplements can be safely used by breastfeeding women, except for InsuBest and BestBody products. Breastfeeding is an important time when the demand for certain nutrients increases, so supplementation may be helpful. However, given your and your childs health, we always recommend consulting a doctor before starting supplementation.

    • 6. Can I supplement BestB12 while using Best B-Complex?
      In most cases, simultaneous use of BestB12 and Best B-Complex is not necessary, because a B-complex supplement already contains vitamin B12. However, in cases of confirmed, significant vitamin B12 deficiency, especially when a higher intake of this vitamin is required, combining both preparations may be justified. This strategy allows, on the one hand, to increase vitamin B12 intake and, on the other hand, to ensure the presence of other B vitamins that participate in metabolic processes and the methylation cycle. In case of doubts regarding the dosage or duration of supplementation, it is advisable to consult a specialist and base the decision on laboratory test results.

    BestB12 – vitamin B12 drops (hydroxocobalamin)

    BestB12 is a dietary supplement intended to supplement the daily diet with vitamin B12 in the form of hydroxocobalamin. It is a solution for people looking for high-quality, simple, and convenient supplementation – without unnecessary additives, in liquid form with a precise pipette. One serving (5 drops) provides 100 µg of vitamin B12 (4000% RI), which helps maintain a consistent intake in a daily routine.

    itamin B12 is one of those vitamins whose deficiency may remain unnoticed for a long time. This is because the body can store it, and the first symptoms are often nonspecific and confused with fatigue, stress, or a “worse period.” At the same time, B12 plays a key role in proper energy metabolism, the functioning of the nervous system, the production of red blood cells, homocysteine metabolism, and the maintenance of normal psychological functions – therefore, it is worth treating it as one of the foundations of conscious supplementation.

    Vitamin B12 – what does it help with?

    Vitamin B12 helps reduce tiredness and fatigue, which is particularly important for people working intensively, living under stress, with irregular sleep, and under high mental load. It also helps maintain normal energy metabolism, i.e., the processes through which the body “obtains energy” from daily nutrition.

    B12 also supports key areas of bodily function: it helps the proper functioning of the nervous system, helps maintain normal psychological functions, and supports the proper production of red blood cells. Additionally, it participates in an important metabolic process by helping maintain normal homocysteine metabolism – a parameter often assessed in lifestyle diagnostics and diet quality assessments.

    Which form of vitamin B12 is best? Hydroxocobalamin vs other forms

    Various forms of vitamin B12 are available on the market – most commonly cyanocobalamin, methylcobalamin, adenosylcobalamin, and hydroxocobalamin. Hydroxocobalamin is a well-tolerated form and is often chosen for long-term supplementation, among other reasons, due to its stability and practical usability in everyday use. It is a form that fits well with the philosophy of “conscious supplementation”: simple, consistent, and free of unnecessary complications.

    BestB12 uses hydroxocobalamin in drop form, allowing convenient intake of vitamin B12 without capsules while maintaining precision in the daily dose.

    Vitamin B12 in drops – why does the liquid form matter?

    Vitamin B12 in drops is a particularly convenient solution for people who do not like capsules, have difficulty swallowing tablets, or simply value simplicity. BestB12 has a liquid form with a dropper, making supplementation quick, repeatable, and easy to incorporate into a morning routine.

    An additional advantage of the liquid form is transparency – you know exactly how much you are taking (5 drops = daily serving), and the product itself has a simple composition: water, glycerine, vitamin B12 (hydroxocobalamin), and a preservative.

    Vitamin B12 deficiency – why does it occur so often?

    Vitamin B12 deficiencies are among the most common micronutrient deficiencies. The cause may be a plant-based diet (B12 naturally occurs in animal-derived products), low gastric acid levels, impaired secretion of intrinsic factor (IF), as well as long-term use of certain medications such as metformin or proton pump inhibitors. An additional lifestyle factor is stimulants (especially coffee and tea), which may affect the overall bioavailability of nutrients in the diet. That is why vitamin B12 often becomes the foundation of a modern, conscious nutritional strategy.

    Who is the BestB12 supplement for?

    BestB12 is a particularly good choice for people on a vegan and plant-based diet, for whom vitamin B12 supplementation is a permanent element of daily nutrition. The product may also interest people who drink large amounts of coffee and tea, as well as those who pay attention to diet quality during periods of increased load. In practice, it is also a solution for people who suspect reduced vitamin B12 absorption (e.g., due to gastrointestinal issues), as well as for those who care about concentration, the nervous system, and overall cognitive performance.

    How to use BestB12? (practical tips)

    The recommended intake is 5 drops dissolved in water and drunk. The preparation should be used in the morning, after a meal, and shaken before use. The package contains 114 servings, which corresponds to 114 days of use. Due to the ingredients used, sediment may appear at the bottom – this does not affect the quality of the product.

    Is vitamin B12 safe? (B12 supplementation in drops)

    BestB12 is a dietary supplement and, when used according to the manufacturer’s recommendations, is intended for daily dietary supplementation. As always, the recommended daily dose should not be exceeded, and the supplement should not be treated as a substitute for a varied diet. Pregnant and breastfeeding women should consult a doctor before using the product, and people with hypersensitivity to any ingredient should not use it.
