Immunity Booster

Hello, Yes, it is possible, but short-term. Immunity booster is based on plant-extract compounds (with vitamin C and D3, Zn, Se). The performance multivitamin has plate of vitamins B, vit E, vit A, vit K, vit C, some metals like Fe, Mg, Zn+Se (Zn and Se are also in immunity booster), Mn, Cu, Cr, I, Mo, D3+K2 (you have only D3 in immunity booster for its imunity power), Maca, Alfa-lipooic acid, Co Q10, cholin and inositol. So, if you are acutelly struggling with some "feeling of flu", you could use both, but do not supplement them permanently (long-term) together. Multivitamin is multi-functional:) And if you want to help yourself acutelly, you can also use additionally to multivitamin the liposomal vitamin C, Zn in chelate form, add D3. And, do not forget to hydrate properly!
