How are we different?

Hydroxocobalamin is a natural form of vitamin B12 found in the human body and many food products. This vitamin has a particularly high bioavailability, a long-lasting repository effect, and detoxification properties.

Hydroxocobalamin can be easily converted into active B12 coenzymes, which makes it a particularly good form of B12 with which to supply the body. A large percentage of the vitamin B12 in the human body is stored in the form of hydroxocobalamin.

Another advantage of hydroxocobalamin is that it circulates in the body for a relatively long time and thus can ensure a lasting, constant supply of vitamin B12. Although other forms of B12, such as the synthetic cyanocobalamin, cannot be retained within the body for long, hydroxocobalamin can effectively remain in the body for longer periods of time, which is why this form of B12 is described as having good "depository" effects. This characteristic has furthermore made hydroxocobalamin a crucial component in therapies for acute vitamin B12 deficiency, such as in vitamin B injections in clinics.

Although hydroxocobalamin is not a coenzyme, it can be easily converted into the B12 coenzyme forms methylcobalamin and adenocobalamin. It is advantageous as a supplement because it is much easier for the body to convert it into one of the two coenzymes than to convert the coenzymes into hydroxocobalamin.

The only additional ingredient is premium acacia fibre from pesticide-free cultivation, used as a natural bulking agent. In contrast to conventional synthetic fillers such as microcrystalline cellulose, which is mixed with nano-particles, we use a natural, fibre-rich foodstuff. Our acacia fibre comes from climate-neutral, sustainable, resource-conserving, fair cultivation.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

Effects

Vitamin B12 (Cobalamin)

Vitamin B12 fulfils a number of important functions in the body: it can help to reduce tiredness and fatigue and maintain a normal energy metabolism; it contributes to the normal functioning of the psyche, immune and nervous systems; supports the formation of red blood cells; and is beneficial for normal homocysteine metabolism. The body also needs vitamin B12 for cell division.

Vitamin B12 acts as a so-called coenzyme in the body, meaning it is necessary for certain enzymes to fulfil their tasks. The associated reactions are directly dependent on vitamin B12 and cannot take place without it.

Natural, Bioactive Vitamin B12

Vitamin B12 (cobalamin) exists in various forms, each with different roles in the body. The natural forms of vitamin B12 that are directly active in the body are referred to as "bioactive coenzymes." Synthetic forms of vitamin B12, such as the commonly used cyanocobalamin, do not have direct vitamin activity and must be converted by the body into a usable form.

Hydroxocobalamin

Hydroxocobalamin is a natural form of vitamin B12 found in many foods. Hydroxocobalamin can effectively remain in the body for longer periods of time, which is why this form of B12 is described as having good "repository" effects. Hydroxocobalamin can be easily converted by the body into the active coenzyme forms when needed.

According to the European Food Safety Authority (EFSA):

Vitamin B12 contributes to:

  • normal energy metabolism
  • normal functioning of the nervous system
  • normal homocysteine metabolism
  • normal mental function
  • normal formation of red blood cells
  • normal function of the immune system
  • reduction of tiredness and fatigue
  • cell division

Dosage

Directions

Take 1 capsule (5000µg vitamin B12) every 5 days with 200ml water, 30 minutes before a meal.

European Union law prohibits the sale of vitamin B12 products in excess of more than 1000µg per day, which is why we offer this product as a weekly dose of 5000µg.

Daily Requirements

The German Nutrition Society (DGE) recommends a minimum intake of 4µg vitamin B12 per day for adults.

B12 Intake

The human body can only absorb a portion of the vitamin B12 found in food and supplements: only about 1–2µg of vitamin B12 can be absorbed at a time via the intrinsic factor, a special protein, with a further 1% absorbed via passive diffusion through the intestine. Calculating total B12 absorption therefore requires taking both of these factors into account. Note: By distributing intake of B12 throughout the day, absorption via the intrinsic factor can be maximised.

According to this formula, our Vitamin B12 5000µg corresponds to an intake of approximately 7µg per day when taken on a weekly basis, or 50µg per capsule.

Food Supplement

Do not exceed the recommended daily intake. Food supplements are not a substitute for a balanced, varied diet and healthy lifestyle. Keep out of reach of young children.

Storage

Store in a cool, dry place away from direct sunlight and heat.

Cofactors

All eight essential B vitamins work very closely together in numerous metabolic processes in the body. In many cases it therefore makes sense to take the vitamins together.
