Can I intake Stressstab (multivitamins) and cecon (ascorbic acid) at once? Everyday once a day?

No. I do not recommend multivits at all = filled wi crap like only 1 form of Vit E, too little D3, and B complex = methyl donors to promote cancer. Take No suppl more than 5 days a week to give the body a break. HRS, MD, FACC
