C vitamini haplar\u0131na dikkat!<\/b><\/p>\n

C vitamini tablet, kaps\u00fcl, pastil, \u015furup ve toz halinde al\u0131nabilir. En iyi C vitamini i\u00e7inde biyoflavonoid, hesperidin, rutin gibi di\u011fer bile\u015fikleri de bar\u0131nd\u0131ran kompleks C vitaminidir. C vitamini haplar\u0131 \u00e7o\u011funlukla m\u0131s\u0131rdan elde edilmektedir. M\u0131s\u0131r ve soya alerjik \u00f6zellikleri olduk\u00e7a y\u00fcksek ve GDO’lu \u00fcr\u00fcnlerdir.
