The reason K2 and calcium are not included is purely due to the fact that the Smart Supplement is a braincare formula first and foremost. Therefore, all the ingredients have been included by our experts with regard to taking care of your brain.
K2, D3 and calcium work together for optimum bone health, so you are more than welcome to take a bone care supplement alongside our formula. However, we would just encourage you to track the vitamin D you are getting if you do so. We are not encouraged to take more than 100mcg per day and we include 45mcg.
Vitamin D only needs K2 for the absorption of calcium rather than the absorption of vitamin D itself and it is only necessary where K2 deficiency is present which is very rare.
