Vitamin B12 (Cobalamin)

Vitamin B12 fulfils a number of important functions in the body. Among other things, 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 in our body to fulfil their tasks. The associated reactions are directly dependent on vitamin B12 and cannot take place without the vitamin.

Vitamin B12 MH3A® Formula

Vitamin B12 (cobalamin) occurs in a variety of different chemical structures, all of which perform different tasks in the body. The natural forms of vitamin B12, which can exert a direct effect on the body, are considered bioactive coenzymes. Synthetic forms of vitamin B12, such as cyanocobalamin, must first be converted into a natural form by the body in order to be effective.

Methylcobalamin and adenosylcobalamin are the bioactive coenzyme forms of vitamin B12. Because they each have different areas of action and take part in completely different reactions, the body is able to convert these forms from one to the other. Methylcobalamin plays a role in the methylation cycle within the cell plasma, a far-reaching function influencing various body processes from blood cell synthesis to the functioning of the nervous system. Adenosylcobalamin, on the other hand, takes effect in the mitochondria, the powerhouse of the cell. There it plays a role in the citrate cycle, the central metabolic cycle for energy production. The third natural form of vitamin B12 is hydroxocobalamin, a form which can be found in many foods. It makes up a significant amount of the total B12 in the blood and binds particularly well to vitamin B12 transport molecules. It is thus not excreted as quickly; hydroxocobalamin is the form of B12 with the highest capacity for building long-term stores in the body and can be easily converted into either of the two active coenzyme forms as needed.

Health Benefits of Vitamin B12

According to the European Food Safety Authority (EFSA), vitamin B12 contributes to:

• Normal energy metabolism
• Normal nervous system functioning
• Normal homocysteine metabolism
• Normal cognitive function
• Normal erythropoiesis
• Normal immune system functioning
• The reduction of tiredness and fatigue
• Cell division

Recommended Dosage

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

European legislation concerning food supplements prohibits the marketing of products which provide more than 1000µg of B12 per day. We therefore suggest taking our Sunday Natural High-Dose Vitamin B12 5000µg on a weekly basis

Daily Requirements

The German Nutrition Society (DGE) recommends a minimum intake of 3µg 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.

In the case of Sunday Natural MH3A® 5000µg, intake can be estimated at approx. 7µg of vitamin B12 per day when taken on a weekly basis, or 50–52µg per capsule.

Food Supplement

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

All eight essential B vitamins work together. Numerous metabolic processes in the body require them; they can only achieve optimal functionality if each vitamin is in sufficient supply. Therefore, in many cases, it makes sense to supplement these vitamins together.

The purity of our formulas is important to us. This is why we have both our raw ingredients as well as our finished products extensively tested by independent laboratories to confirm purity and active ingredient content. Here, we have provided the results of some of the tests carried out on this product.
