VITAMIN D3 & K2 is a food supplement, in liquid form, containing vitamins D3 and K2. This combination contributes to the maintenance of normal blood calcium levels and the normal condition of bones. The liposomal formulation technology results in greater absorption of the vitamins compared to other forms of intake such as tablets.

Vitamin D3

Vitamin D3, or sunshine vitamin, is one of the forms of vitamin D that can be absorbed by our body. Vitamin D is synthesized in the skin with the help of the sun, but it is also found in certain foods, mainly fish and eggs. It is necessary to regulate the functioning of calcium and phosphorus, which are involved in bone health.

Vitamin D has an effect:

• In the bones: increases the absorption of calcium, the main component of bones. It is used to prevent the development of osteoporosis and reduce bone loss.
• In the immune system: in recent years, its contribution to strengthening the immune system has been proven. High levels of vitamin D protect against infections and reduce the symptoms and severity of viruses and the common cold. In addition, it can protect against autoimmune diseases, and even against several forms of cancer.
• In the cardiovascular system: Studies have shown that vitamin D deficiency increases the risk of developing cardiovascular disease. Healthy levels of the vitamin in the blood can contribute to normal blood pressure and vascular health.
• In the respiratory system: prevents the development of respiratory infections and helps to improve asthma. 

Deficiency of vitamin D is quite easy to create. People who are not often exposed to sunlight and who do not receive exogenous amounts of vitamin D, have an increased risk of developing a deficiency or deficiency. This can result in bone degeneration and the development of osteomalacia, rickets or osteoporosis. Older people in particular are at greater risk of vitamin D deficiency and are recommended to take D3 supplements to maintain healthy blood levels.

Vitamin K2

Vitamin K is also one of the fat-soluble vitamins, like vitamin D. We find it in green leafy vegetables, yellow cheeses and egg yolks, but it can also be produced by the intestinal microflora. Vitamin K includes two classes, phylloquinone (K1) and menaquinones (K2). Menaquinones exist in several forms, of which MK-7 is the most active. 

K1 plays an important role in the blood clotting mechanism. On the other hand, K2 has an effect on the health of bones and teeth, but it also prevents the precipitation of calcium in the vessels. Thus, it prevents the creation of calcifications in the vessels, keeping the cardiovascular system healthy. Its administration, mainly in women with reduced bone density, seems to significantly improve the situation and prevent the creation of fractures.

Coadministration of D3 with K2

Vitamins D3 and K2 are critical for healthy calcium metabolism as they play an essential role in the deposition of calcium in skeletal tissue. The administration of vitamin D3 for long periods of time activates the production of some proteins that are activated in the presence of K2. Their activation helps to "guide" calcium to the bones, so that it is not deposited in the vessels. Therefore, the combination of these two vitamins offers the maximum absorption of calcium from the bones and effectively leads to the improvement of bone density, without burdening the health of the vessels.

Liposomal technology and benefits

Liposomes are man-made particles in a spherical shape, in the center of which amounts of plant or chemical nutrients can be placed. They act as transport vehicles for the active substances in our body, presenting important advantages:

1. protect the active substance from oxidation and degradation at acidic pH of the stomach
2. increase absorption and bioavailability compared to free and other conventional pharmaceutical carriers (tablets, suspensions and capsules).

The dimensions of liposomes, depending on the method of their preparation and the physicochemical characteristics of their structural units, are of the order of nanometers up to the order of a few micrometers.

Liposomes are made from building materials like those of our cells (phospholipids). Because of this, they have advantages related to 'friendliness' to human tissues. They have the ability to transport lipophilic bioactive molecules, which do not dissolve easily in aqueous media and therefore have absorption and bioavailability problems, e.g. vitamins, curcumin, etc. But also water-soluble or amphiphilic molecules, improve their dissolution rate and absorption through the gastrointestinal tract.

Liposomal technology can improve the therapeutic efficacy of dietary supplements. They are an innovation in this area, giving high added value to the final dosage form.
