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)

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.

NATURAL, BIOACTIVE VITAMIN B12

Vitamin B12 exists in different chemical forms, each with different functions within the body. The natural forms of vitamin B12 that can be readily absorbed by the body are described as "bioactive coenzymes". Synthetic forms of Vitamin B12 such as cyanocobalamin must be first converted into a natural form by the body in order to be effective, which is why we use naturally bioactive forms of Vitamin B12 that the body can directly use.

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 "depository" effects. Hydroxocobalamin can be easily converted by the body into the active coenzyme forms when needed.

Health Benefits of Vitamin B12 According to the European Food Safety Authority (EFSA):

Vitamin B12 contributes to:

  • Normal energy-yielding metabolism
  • Normal functioning of the nervous system
  • Normal homocysteine metabolism
  • Normal psychological function
  • Normal red blood cell formation
  • The normal function of the immune system
  • The reduction of tiredness and fatigue
  • Vitamin B12 has a role in the process of cell division

Dosage

Recommended Dosage

Dosage Take 1 capsule with 200ml water once every 5 days, 30 minutes before a meal.

European Union law prohibits the sale of vitamin B12 products in excess of 1,000µg per day, which is why this product is offered as a weekly dose.

Daily Requirements

The German Nutrition Society (DGE) recommends a minimum of 3µg vitamin B12 per day for adults.

B12 absorption

The human body can only absorb small quantities of vitamin B12 through food and supplements. Only approximately 1-2µg vitamin B12 per dosage can be actively absorbed through the special "intrinsic factor" protein and a further 1% of the dosage is absorbed through passive diffusion. The total supplement intake is estimated based on the combination of these two factors. Due to the time-shifted intake, the active uptake via the intrinsic factor can be utilised several times.

According to this calculation, Sunday Natural Vitamin B12 5,000µg enables an intake of 50µg per capsule as weekly dosis, i.e. 7µg Vitamin B12 per day.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.

Storage

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