This potent and innovative formula can support immune, cardiovascular and musculoskeletal health. Using specialised technology, Medlab produces vitamin D3 and K2 in ‘nano particles’, which are easily absorbed. Delivery of the spray to the inner cheek optimises absorption, as the lining of the mouth is much more permeable than the gut. Vitamin D3 is a vital nutrient for immunity, yet 60% of Hong Kongers are believed to be deficient. This vitamin raises levels of secretory IgA, an essential antibody which plays a key role in your body's immune response.  NanoCelle D3+K2 is also an extremely supportive formula for bone health. Vitamin D3 assists the absorption of calcium and phosphorus, which are both crucial nutrients for building and maintaining bone health. Vitamin K2 promotes the binding of calcium to the bone. Both nutrients support healthy bone metabolism and density. Vitamin K2 also assists the process of wound healing.
