I take the capsules already 2 to 3 weeks, directly together with c 1000ie a, mostly in the morning with OPC, for lunch I take D3 K3 a, I could still find no side effects, from left, take the other candidates got enough vitamin b with food on, or they lack other vitamins or zinc .... .... as already written, I can not explain why some respond so brutal to me. I think it's just a little sad that it is so cut down here, and the blame lies with a left himself. I take only one tablet, because as I said, other dietary supplements swallow, but I think this self-medication must each decide for themselves, and do not forget to inform themselves what vitamins you involve with this complex. Every body is individual. Everyone has different eating habits and a different metabolism, vl ransom and swallow not always plan but the interactions draw with other trace elements into consideration, and these perform well, otherwise I find the product ok. I have no chemistry lab to disassemble it, but I think it's good that we are (still?) Gets such Präperate.
