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 only other ingredient is premium gum arabic, cultivated without the use of plant protection products. In contrast to microcrystalline cellulose, a widely used synthetic filler often mixed with nanoparticles, gum arabic is a natural, fibre-rich food. The soluble dietary fibres serve as a food source for bifidobacteria and lactobacilli in the intestine. Our fair trade gum arabic is climate neutral and is sustainably cultivated to conserve resources.

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. 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

Dosage

Recommended Dosage

Take 1 capsule with 200ml water daily, 30 minutes before a meal.

Daily Requirements

Vitamin B12

The National Health Service (NHS) recommends a daily intake of 1.5μg of vitamin B12 (cobalamin). However, it is important to note that individual vitamin B12 needs may vary according to age, dietary habits, genetics and other factors.

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.

According to this calculation, Sunday Natural B12 MH3A-D® 1000µg in drops enables an intake of 10-12µg Vitamin B12 per drop.

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

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.
