Osavi Vitamin D3 + K2 - 4000IU + 150mcg - 120 softgels

Are you looking for a way to improve your immunity? Or are you worried about weak muscles and bones? You are probably missing the sunshine vitamin. Receiving vitamin D3 with vitamin K2 can improve your overall condition and prevent many diseases. Convince yourself of its effectiveness.

Vitamin D participates in the process of cell division and is significant for proper functioning of the immune system and improving the condition of the locomotor system. In combination with vitamin K contributes to the assurance of muscle and bone health. The sunshine vitamin helps in maintaining optimal levels of calcium in the blood, and affects the proper absorption of calcium and phosphorus (the right amount of vitamin D increases the absorption of calcium by about 30-40%, and phosphorus by about 80% [1]). It has been proven that vitamin K in combination with vitamin D increases total bone mineral density (BMD) [2] and that K2 MK-7 (menachinon-7) affects the production of collagen, which has a positive effect on the quality and strength of the skeleton [3]. K2 also contributes to normal blood clotting. Vitamins D3 and K2 work in harmony to ensure optimal functioning of the body.

Vitamin D is a fat-soluble vitamin. Among its most important types are ergocalciferol (D2) and cholecalciferol (D3) – the latter is supplied mainly by skin synthesise. Substance deficiency is common across all age and ethnic groups. It is assumed that its insufficient amount may affect even half of the population. This is mainly due to the modern lifestyle, which is associated with limiting access to the main source of this vitamin, i.e exposure to natural sunlight. Vitamin D is called the sunshine vitamin for a reason, as humans synthesise D3when exposed to UVB light on the skin. It can also be obtained from the diet by eating fatty fish - e.g. mackerel, salmon and herring [1].

Vitamin K occurs naturally in the form of K1 (phylloquinone) and K2 (menaquinone). There are many subtypes of vitamin K2, however the menachinon-7 (marked as MK-7) is the most absorbable form of vitamin K2 with confirmed stability and activity. It plays a key role in regulation of calcium metabolism– thanks to this, calcium reaches where it is most needed in the body and does not cause damage by accumulating in undesirable places. K2 is found in fermented foods and of animal origin [4].

Deficiency of vitamins D3 and K2 is associated with decrease in bone mineral density, which increases the risk of osteoporosis and osteopenia, as well as skeletal deformities. Not getting enough of the sunshine vitamin also causes muscle weakness, which makes daily functioning difficult and puts you at risk of frequent falls that can lead to fractures. Due to the fact that the supply of an adequate supply of vitamin D3 diet is not easy, the use of dietary supplements may prove helpful [1, 5].

Our supplement is a combination of vitamin D3 (Quali®-D) of natural origin and highly bioavailable vitamin K2 (K2VITAL® – K2 MK-7 identical to the K2 molecule found in nature). OSAVI Vitamin D3 + K2, 4000 IU + 150 μg is in the form of soft and easy to swallow capsules filled with MCT oil obtained only from oil produced from the fruit of the coconut palm Cocos nucifera L. One portion contains up to 4000 IU of vitamin D3, which corresponds to 100 μg (2000% NRV) and 150 μg of vitamin K2 (200% RWS)
