How are we different?

Not all forms of vitamin B12 show the same level of efficacy. Conventional supplements often contain only synthetic forms of vitamin B12, which must first be converted into biologically active forms by the body before they can be utilised. Sunday Natural Vitamin B12 MH3A® provides the full spectrum of natural and bioactive forms of vitamin B12.

Conventional vitamin B12 supplements usually contain only one active ingredient. However, several active forms of B12 occur in our bodies and in natural foods. All forms exhibit different effects and are metabolised in part via different pathways, resulting in absorption rates unique to every individual.

Although standard practice to supply vitamin B12 in an isolated, synthetic context, our pioneering MH3A® formula offers the vitamin in the same way as it occurs in food: as a mixture of all three natural and bioactive forms, which allows the natural synergistic effects between them to occur (they each fulfil completely different tasks in the body and have different focal points of action). Our MH3A® formula contains these three forms of vitamin B12 in an equal ratio, spread across a total of five active forms of B12. This formula thus provides a foundational supply of vitamin B12 as found in nature, where all three forms are always found in a harmonious combination, both in our bodies and in the foods we eat. In contrast, the majority of products available on the market contain only one of the three B12 active ingredients: either methylcobalamin, hydroxocobalamin or adenosylcobalamin.

The advantage of lozenges is their ability to be directly absorbed through the mucous membrane of the mouth by means of passive diffusion. The citamins can then enter the bloodstream directly, without first passing through the liver—as would be the case with intestinal absorption. As a result, any potential digestive difficulties in the gut can be completely avoided, significantly increasing bioavailability.

Our high-quality lozenges are based on non-GMO guar gum, allowing us to completely omit the controversial yet common additives in conventional lozenges, including magnesium stearate, sweeteners, colourings and animal products such as gelatine.

Effects

Vitamin B12 (Cobalamin)

Vitamin B12 performs a variety of important functions in the body: it can help to reduce tiredness and fatigue and to maintain normal energy metabolism, it contributes to the normal functioning of the psyche as well as the immune and nervous systems, it plays a role in the formation of red blood cells (also known as erythropoiesis) and it supports normal homocysteine metabolism, as well as being required in the process of cell division. Vitamin B12 also acts as a coenzyme in the body. This means that certain enzymes in our body require B12 in order to fulfil their tasks. In other words, many enzymatic reactions are directly dependent on vitamin B12 and cannot take place without it.

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

Dosage

Recommended Dosage

Take 1 lozenge (1,000µg B12) daily. Allow to dissolve in the mouth and drink plenty of water.

We recommend placing the lozenge under the tongue or in the cheek and allowing it to dissolve for as long as possible without swallowing.

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® 1,000µg, intake can be estimated at 10 to 12µg of vitamin B12 per lozenge.

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.

Cofactors

Vitamin B12 and folate work together closely in the body and can only unleash their full potential when both are available in sufficient quantities. Both cofactors are necessary to convert harmful homocysteine into methionine.

In many cases it is therefore advantageous to take both vitamins at once. An imbalance between B12 and folate can lead to a functional deficiency, while proper efficiency is only guaranteed with a sufficient supply of both.

In cases of a B12 deficiency, abnormal folate metabolism can lead to methylfolate build up, which in turn can cause negative side effects including irritability and soreness.
