How are we different?
Adenosylcobalamin is one of the 2 natural bioactive coenzymes of vitamin B12, which can be utilised directly by the body without conversion and therefore has excellent bioavailability. It is the dominant form of vitamin B12 in our organs and tissues; it is also the form through which vitamin B12 is stored in our liver. Adenosylcobalamin is a particularly natural source of vitamin B12 for humans because it is the most common form of B12 found in food and it is also produced by bacteria in our intestinal flora.
Adenosylcobalamin acts in the mitochondria – the "powerhouse" of our cells – as part of the citric acid cycle, which is the essential metabolic cycle process of producing energy. The citric acid cycle supplies not only energy, but also substances necessary for many other functions in our bodies.
Adenosylcobalamin is said to have a special effect on energy metabolism, which is why it is popular with athletes and for treating fatigue. It is also suitable for daily supplementation.
The only additional ingredient is premium gum arabic 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 gum arabic 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
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.
Natural and Bioactive Vitamin B12
Vitamin B12 (Cobalamin) exists in various chemical 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.
Adenosylcobalamin
Adenosylcobalamin is one of the 2 natural bioactive coenzymes of vitamin B12, which can be utilised directly by the body without conversion and therefore has excellent bioavailability.
Adenosylcobalamin is the dominant form of vitamin B12 in our organs and tissues; it is also the form through which vitamin B12 is stored in our liver. It is a particularly natural source of vitamin B12 for humans because it is the most common form of B12 found in food and it is also produced by bacteria in our intestinal flora.
Adenosylcobalamin acts in the mitochondria – the "powerhouse" of our cells – as part of the citric acid cycle, which is the essential metabolic cycle process of producing energy. The citric acid cycle supplies not only energy, but also substances necessary for many other functions in our bodies.
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
Dosage
Directions
Take 1 capsule with 200ml water daily 30 minutes before a meal.
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.
According to this calculation, Sunday Natural Adenosylcobalamin Vitamin B12 1000µg enables an intake of 10–12µg vitamin B12 per day.
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.
