SunDevit®, a new product with a special complex of vitamins D3 and K2, enters the Russian market

The biotech company Petrovax Pharm, one of the leading Russian manufacturers of innovative immunobiological products and vaccines, has announced the launch of its new product SunDevit in the Russian market. This complex contains a special combination of vitamins D3 and K2.

SunDevit is a latest generation complex. The main advantage of the product is a specially selected dosage of vitamin D3 in combination with vitamin K2 for the support of immune system and health of muscles, bones and joints.

Vitamin K2 (menaquinone) enhances the beneficial properties of vitamin D3 (cholecalciferol) and contributes to better distribution of calcium, increases the efficiency of bone mineralization, and prevents calcium deposition in the walls of blood vessels, in kidneys, joints and soft tissues.

Our bodies require vitamin D to absorb calcium and phosphorus, reinforce the immune system, regulate metabolism as well as maintain the health of the reproductive system. A lack of sunlight, an unbalanced diet, and problems with vitamin D intake from food can result in vitamin D deficiency, which sometimes leads to serious consequences such as impaired bone mineralization, rickets in children and osteomalacia in adults, osteoporosis, chronic fatigue, difficulty sleeping, concentrating, and remembering.

A person can get vitamin D, for example, by sunbathing for 5 to 15 minutes three times a week[1]. However, it may be not enough to correct vitamin D deficiency by sunlight alone. Natural sources of the vitamin such as fatty fish, egg yolks, butter and hard cheeses should be regularly included in the diet. When combined with a balanced diet, dietary food supplements can also help correct vitamin D deficiency by the optimal dosage required for the body.

Vitamin K2, in turn, allows you to maintain a balance of calcium by promoting proper distribution of the mineral in the body. The fact is that prolonged intake of vitamin D3 may require monitoring of blood calcium levels. Once absorbed, calcium can be deposited in vascular walls and does not necessarily reach the bone. This is fraught with adverse effects. By activating matrix Gla protein (MGP) and osteocalcin, vitamin K2 (menaquinone) contributes not only to reduced risk of calcium deposition in blood vessels, kidneys, joints and soft tissues, but also to more effective bone mineralization.

Vitamin K2 has been clinically proven to significantly inhibit calcium deposition in vascular walls[2]. Calcium and vitamin D3 cannot provide a complete bone building process without vitamin K2[3][4].

The SunDevit formula allows you to maintain physical endurance, performance, cognitive function, and cellular energy production, contributes to the immune system reinforcement and mitigates the risk of infection, including ARVI.

The product contains the optimum dosage 2000 IU to maintain normal levels of vitamin D in the body, according to the clinical recommendations of the Russian Association of[5] One pack of the vitamin complex SunDevit may be enough for two courses. The product is indicated for adults aged 18 years and older.
