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 are excellently tolerated and also 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.

Vitamin B12 MH3A® Formula
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.
Dosage
Dosage
Directions
Take 1 capsule with 200ml water daily, 30 minutes before a meal.
Sunday Natural Vitamin B12 MH3A® for Children 15µg comes in easy-to-swallow mini capsules. For small children, break open the capsule and mix the ingredients into liquid or soft foods.
Daily Requirements
The German Nutrition Society (DGE) recommends a minimum intake of 2µg of vitamin B12 per day for children aged 4 to 7; for children aged 1 to 4, a daily dose of 1.5µg is recommended
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 MH3A® 15µg corresponds to an intake of 2–2.15µg per capsule.
Contraindications
Not suitable for children under the age of 3.
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.

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.
